Patent Application
20200156125
The present disclosure relates generally to the field of recycling and waste processing, including organic waste processing and byproducts thereof.
Various systems, methods, and products relate to recycling and/or organic waste processing, including byproducts that can be obtained using methods related to processing, recycling and/or disposal of organic waste and/or green waste. Some problems exist with regard to processing, recycling, and/or disposing of organic material and/or green waste. The present application overcomes historical challenges and improves processing, recycling, disposal, and production of useful byproducts in the context of waste processing.
Waste products have been filling landfills across the world for decades. In recent years, cities and countries have struggled to deal with the increased waste. Attempts at waste management have involved various programs, including recycling programs. How the waste material is treated often depends on the content and/or makeup of the waste material. For example, inorganic waste material, such as plastics, can often be transformed into other products or reused for other purposes. Similarly, some organic waste material can be turned into compost or fertilizer. Yet some organic waste material does not biodegrade very quickly and may require additional processing. For example, certain types of organic waste material may be too fibrous and therefore may take years to decompose or degrade on its own. Due to this, in many instances when these waste materials are taken to a landfill a stopgap solution may be to simply cut the waste material into smaller fragments before disposal. However, these stopgap solutions are often insufficient. An example of these types of organic waste material includes palm fronds.
Current approaches of sending certain types of organic matter into landfills are problematic, in part because landfills themselves cause many problems. For example, landfills produce toxic liquids that can get into groundwater and other waterways. This is particularly true for nonbiodegradable waste materials. Moreover, landfills are where many products go to decompose, yet not all of even these waste materials are exposed to oxygen and therefore are not able to decompose aerobically. Therefore, landfills produce high volumes of greenhouse gases that are emitted into the atmosphere.
The build-up of waste materials that are slow to decompose or do not decompose at all can be expensive for cities and countries. The waste material can build up on itself and avoid natural creation of useful byproducts. For example, in Phoenix Ariz., it is estimated that 34,000 tons of palm fronds are collected each year. This accounts for up to 3.4% of the city's waste and may cost the city half a million dollars or more to place in a landfill. Moreover, the fibrous nature of the palm fronds creates a unique challenge for processing them. The palm fronds can clog green waste processing facility machinery and may take up large amounts of city resources, including time and money.
To combat these and other challenges associated with the recycling and/or disposal (e.g., repurposing) of organic waste material, this application describes a variety of systems, methods and products, including byproducts of organic waste material that can be obtained through improved methods of their processing, recycling, and/or disposal. This application also describes various methods for recycling and/or disposing of these organic materials, including methods for obtaining byproducts associated with the processing of these organic materials.
In some cases it can be advantageous to dispose of these organic waste materials by converting them into useful products. For example, organic materials can be turned into fuels, fertilizers, structural components, and/or animal feeds, etc. Yet with certain organic materials, the production of these byproducts has proven challenging. In particular, it can be challenging to adequately process organic and other waste products, such as palm fronds. Because of their toughness, disposing of palm fronds or forming them into a usable product has presented various difficulties. Various embodiments described herein relate to methods of preparing and processing palm fronds for convenient disposal, recycling, repurposing, transport, storage, mixing with additional components, and/or consumption. This can make it much more efficient and productive to generate an animal feed based on palm fronds, rather than discarding them as is frequently done.
In some embodiments, systems and methods for processing organic waste into a bio-friendly byproduct can include introducing a first waste material comprising palm frond particles into a first grinder configured to expel particles having a diameter no greater than three inches, the first waste material having a moisture content below 20% by weight. The first grinder can be configured to grind the first waste material into first particles having a length less than three inches. The first particles of the first waste material can be introduced into a second grinder configured to expel particles having a length and/or diameter no greater than one inch. The second grinder is used to grind the first particles into second particles having a length less than 1 inch. A second waste material comprises palm dates that can be introduced into a third grinder configured to expel particles having a length and/or diameter no greater than one inch, the second waste material having a moisture content below 15% by weight. A third grinder is used to grind the second waste material into grinds and/or crumbles having a length and/or diameter less than one inch. The first waste material and the second waste material can be introduced into a mixer at a ratio of between 5:3 and 4:1. In some embodiments, the ratio can be 1:1. In some embodiments the ratio can be 2:1. Other ratios and various mixtures are contemplated as described in more detail herein. A mixer can be used to mix the first waste material and the second waste material into a mixture. In some embodiments, nutritional additives can be added. Ratios and types of nutritional additives are described further herein. Additional grinders may also be used before and/or after mixing. Byproducts can be extruded, bagged and/or otherwise packaged for transport and/or delivery. In some aspects, methods include arranging for a first waste material comprising palm fronds to dry until the first waste material reaches a moisture content below 20% by weight. In some aspects, arranging for the first waste material comprises palm fronds to dry comprises using a tumble dryer. In some aspects a second waste material comprising palm dates is arranged to dry until the second waste material reaches a moisture content below 15% by weight. The second waste material comprising palm dates can dry using a tumble dryer. Some aspects include the step of mixing a binding agent comprising oil configured for consumption into the mixture. In some embodiments, the mixture comprises between 25% and 65% binding agent by weight. The binding agent comprises canola oil in some embodiments. In some aspects, the method includes the step of mixing a cereal additive into the mixture, wherein the mixture comprises between 3% and 16% cereal additive by weight. The cereal additive may have a substantial fiber content. For example, the cereal additive may include a fiber content of at least 1% by weight. In some designs, the cereal additive used (e.g., certain low-grade wheats) may have a fiber content greater than about 5% by weight. Certain cereal additives (e.g., whole wheat) may have fiber content between about 5% and 15%. One or more of such cereal additives may be used to supply a target amount of edible fiber to the resulting extrusion.
Some aspects include the step of using an extruding machine, extruding the mixture into pellets having a diameter less than 0.8 inches. Other sizes are also contemplated. In some embodiments, the first waste material has a moisture content of between 5% and 15% by weight. In some embodiments, a first waste material is arranged to dry until the first waste material reaches a moisture content of between 5% and 15% by weight. In some systems and methods, the mixture is introduced into a fourth grinder. Some applications include mixing a roughening additive into the mixture. A roughening additive can be selected from the group consisting of wheat, buckwheat, milo, alfalfa, soy, corn, hay, oats, rice, barley, rye, millet, sorghum, quinoa, or grass. A calcium additive can be added into the mixture in some embodiments. The calcium additive can be selected from the group consisting of oyster shell, a salt comprising calcium or a calcium derivative, calcium carbonate, limestone, calcium monophosphate, calcium diphosphate, and egg shells.
One byproduct that can be produced from waste material is animal feed. World demand for animals and animal products is tremendous and continually growing. The U.S. cattle and dairy industries alone are billion dollar industries. They involve millions of head of cattle that consume billions of dollars of feed annually. Simultaneously, as described above, disposing of palm fronds and waste products that include palm fronds and other palm products has created its own source of challenges. Yet, the disposal of palm-based waste products as a means for feeding animals can provide two concurrent benefits. Animal feeds can come from a variety of sources, but they typically involve a significant component that is from crops grown specifically purposed for animal feed. Many such feed components are susceptible to drought and may struggle in arid conditions. For example, alfalfa, which is regularly found in cattle feed, struggles during dry and hot seasons. The tremendous demand for cattle feed can strain resources.
Various waste byproducts that can be converted into, for example, animal feeds described herein can be based on palm fronds. Palm trees are found throughout the world in arid locations and palm fronds are frequently viewed as a source of waste or trash. Palm fronds are commonly burned or chopped up to be dispersed. However, palm fronds have a variety of nutrients.
Generally, palm fronds have an estimated Total Digestible Nutrient (TDN) content that can be greater than or equal to approximately 40% and/or less than or equal to approximately 60%. For example, palm fronds from Mexican Fan Palms (Washingtonia Robustas) have an estimated TDN content of approximately 51.8% on a dry matter basis. Similarly, Deglet Noor palm fronds can have a TDN content of approximately 52.1% on a dry matter basis. Oil palm fronds have been estimated to have a metabolizable energy (ME) content of approximately 5.65 MJ/kg. Palm fronds harvested during the spring, such as during and between March and May, can have higher energy and TDN contents than they do during other times during the year. Rather than being discarded, such palm fronds can be used in animal feed, helping generate an animal feed that is based on recycled products. Palm-based animal feeds can be used to feed a variety of animals, including horses or ruminants such as cattle, sheep, goats, pigs, or camels.
Many varieties of palms grow palm fruit, such as dates, which are also very nutritious. Generally, dates can have a TDN content that is greater than or equal to approximately 65% and/or less than or equal to approximately 90%. For example, dates from a Deglet Noor Palm tree can have a TDN content of approximately 87.9% on a dry basis. Dates from Canary Palms can have a TDN content of approximately 86.7% on a dry basis. In various embodiments described herein, dates and palm fronds can be combined in different forms and quantities in order to create a nutritious, effective, and sustainable animal feed from what was previously considered largely waste. Additionally, the main products of this feed can be grown in hot and dry conditions. In fact, these sources can thrive in conditions that might destroy products currently used in cattle feed.
According to some aspects, a palm frond and date based animal feed comprises about a 50:50 by weight mixture of palm fronds and dates, wherein the palm frond and date based animal feed comprises larger palm frond-date particles and smaller palm frond-date particles, wherein the larger palm frond-date particles and smaller palm frond-date particles are prepared by the process of: obtaining raw palm fronds with a moisture content of between about 1-15%; obtaining raw dates with a moisture content of less than about 10%; combining four parts by volume raw palm fronds with one part by volume raw dates and grinding the palm and dates together using about a ¼ inch to a 2 inch grinder; sorting the palm frond-date mixture in a trommel equipped with openings from about a ¼ inch to about a ½ inch in diameter; collecting the larger palm-date hay particles; collecting the smaller palm-date fine particles which pass through the screen of the trommel; mixing the palm frond-date hay particles and the palm frond-date fine particles in a ratio of between about 2:1 and 1.5:1 by volume to obtain palm frond and date based animal feed.
In some other aspects obtaining raw palm fronds with a moisture content of less than about 10% and/or less than about 15% are also contemplated. In some aspects, the raw dates contain the skin, the flesh, and/or pits of the fruit.

In some aspects, the raw dates contain the skin, the flesh, and/or pits of the fruit. In some aspects, the sweet palm hay has a total digestible nutrient (TDN) of greater than 50%, 55%, 60%, 65%, 70% or 75% of the dry matter basis. In some aspects, the sweet palm hay has a relative feed value (RFV) of greater than 170, 185, 200, 215, 230, 245 or 260. In some aspects, the raw palm fronds comprise palm fronds selected from the group consisting of Washingtonia Robusta palms, Washingtonia Filifera palms, and Phoenix Canariensis palms. In some designs, the palm fronds are selected from the group consisting of oil palms, fan palms (e.g., Borassus palm), date palms, and coconut palms. In some aspects, the raw dates comprise dates from a Deglet Noor palm or a Canary Palm. Some aspects further comprise the step of introducing the packaging the sweet palm hay into a bag. Some aspects further comprise the step of storing the sweet palm hay.
According to some aspects, a palm frond and date based animal feed comprises a mixture of palm frond component and a date component, wherein the palm frond component has a moisture content of between approximately 1% and approximately 15%; wherein the palm frond component comprises (i) palm fronds of approximately less than or equal to 2 inches in length and (ii) palm frond powder; wherein the date component has a moisture content of approximately 10% or less; and wherein the palm frond and date based animal feed comprising between 40-60% by weight palm frond component and 40-60% by weight date component.

In some aspects, the raw palm fronds comprises palm fronds selected from the group consisting of Washingtonia Robusta palms, Washingtonia Filifera palms, and Phoenix Canariensis palms. In some aspects, the raw dates comprises dates from a Deglet Noor palm or a Canary Palm.
According to some aspects an about 50:50 ratio by weight of a ground palm frond and ground date mixture is advantageous as a base feed for animals. For example, in one aspect, a double grind process for obtaining an approximately 50:50 ratio by weight of a ground palm frond and ground date mixture is advantageous as a base feed for a dairy cow. Additional nutritional components can be added to the palm frond and date base, including, for example, protein additives. In some aspects roughage can be added. In some aspects, a fruit/vegetable component can be added. In some aspects a sugar component can be added. In some aspects a roughening component can be added. In some aspects the feed mixture can be bagged. According to some aspects the double grind process and preferred ratios are advantageous to achieve a sweet palm hay that has a total digestible nutrient (TDN) of greater than 50%, 55%, 60%, 65%, 70% or 75% of the dry matter basis. In some aspects, the sweet palm hay has a relative feed value (RFV) of greater than 170, 185, 200, 215, 230, 245 or 260. Additional aspects and alternative combinations are described further herein for various animal feeds, the teachings of which may be relied upon individually or collectively in other advantageous combinations.
In some embodiments, additional additives can be combined with palm fruit and palm fronds in order to adjust nutritional content. For example, nutritional additives, such as urea, can be included to increase the available levels of nutritional content, such as protein, within the animal feed. In some embodiments, nutritional additives, such as wheat, corn, or other components described herein can be included to increase the available levels of nutritional content, such as protein, within the animal feed. Various ratios of palm fronds, palm fruit, and nutritional additives are described herein.
In some embodiments, feeds with palm fronds, palm fruits, and additives such as urea, wheat, sorghum, milo, and/or other suitable additives including varieties of grains, can serve as an independent animal feed. The various benefits of palm and palm fruit, however, make them desirable for use together or independently in different combinations with different types of animal feeds. Thus, in some embodiments, feeds with palm fronds, palm fruits, and additives such as urea, wheat, and/or other suitable additives, can serve as a base feed to be combined with additional components depending on the desired characteristics of a final feed. In some embodiments, palm fronds themselves can serve as a base feed to be mixed with additional components. In some embodiments, palm fruit and/or seeds can be combined with general base feeds, such as alfalfa, soy, corn, hay, or grass, which can also be mixed with a portion of palm fronds.
According to various embodiments described herein, an animal feed can include a processed palm frond component, a palm fruit component, and a nutritional additive. The palm fruit component and the nutritional additive can have a ratio by weight between 5:1 and 7:1. In some embodiments, the palm fruit can be dates. In some embodiments, the nutritional additive can be urea. In some embodiments, the nutritional additive can be wheat. In some embodiments, palm fruit component and the nutritional additive have a ratio by weight of approximately 6:1.

In some embodiments, shredding, chopping, or grinding the palm fronds includes shredding the palm fronds. In some embodiments, the palm fronds can be chopped after they are shredded. In some embodiments, the palm fronds can be ground after they are chopped.
According to various embodiments described herein, a method of making an animal feed can include collecting palm fronds and drying the palm fronds in wind rows. The palm fronds can be shredded, chopped, and/or ground when dried to a desired moisture content. The palm fronds can be combined with a palm fruit component, such as dates, to the palm fronds. The dates can be combined, for example, in a ratio of 8 units by volume of palm fronds for every unit by volume of dates. In some embodiments, the dates can be combined in a ratio of 8 pounds of date for every 50 pounds of palm fronds. In some embodiments, the palm frond and date mixture can be chopped and/or ground. This mixture can be fed through a mill to collect mill run, such as wheat or other grain or material. In some embodiments, the resulting mixture can have approximately 30% mill run by weight. In some embodiments it can have more or less.

This application describes a variety of systems, methods and products, including byproducts of organic waste material that can be obtained through improved methods of their processing, recycling, and/or disposal. This application also describes various methods for recycling and/or disposing of these organic materials, including methods for obtaining byproducts associated with the processing of these organic materials. In some cases it can be advantageous to dispose of these organic waste materials by converting them into useful products. For example, organic materials can be turned into fuels, fertilizers, structural components, and/or animal feeds, etc. Yet with certain organic materials, the production of these byproducts has proven challenging. In particular, it can be challenging to adequately process organic and other waste products, such as palm fronds.
In some embodiments, systems and methods for processing organic waste into a bio-friendly byproduct can include introducing a first waste material comprising palm frond particles into a first grinder configured to expel particles having a length and/or diameter no greater than three inches, the first waste material having a moisture content below 20% by weight. The first grinder can be configured to grind the first waste material into first particles having a length less than three inches. The first particles of the first waste material can be introduced into a second grinder configured to expel particles having a length and/or diameter no greater than one inch. The second grinder is used to grind the first particles into second particles having a length less than 1 inch. A second waste material comprises palm dates that can be introduced into a third grinder configured to expel particles having a length and/or diameter no greater than one inch, the second waste material having a moisture content below 15% by weight. A third grinder is used to grind the second waste material into grinds and/or crumbles having a length and/or diameter less than one inch. The first waste material and the second waste material can be introduced into a mixer at a ratio of between 5:3 and 4:1. In some embodiments, the ratio can be 1:1. In some embodiments the ratio can be 2:1. Other ratios and various mixtures are contemplated as described in more detail herein. A mixer can be used to mix the first waste material and the second waste material into a mixture. In some embodiments, nutritional additives can be added. Ratios and types of nutritional additives are described further herein. Additional grinders may also be used before and/or after mixing. Byproducts can be extruded, bagged and/or otherwise packaged for transport and/or delivery.
One category of useful byproducts is animal feeds. In certain embodiments, waste material comprises palm fronds. Byproducts formed with a base of palm fronds and combined with flesh of fruit, such as palm fruit (e.g., dates), can be a sustainable and affordable feed product that can be developed in hot climates or anywhere the disposal of palm waste takes place. Palm fronds with less than a threshold moisture content are shredded, chopped and/or ground, and mixed with palm fruit. Additives such as urea can increase the nutritional content. Waste byproducts that include palm fronds, palm fruit, and/or additives can serve as a base feed for other components. Palm fronds can also serve as a base feed for other components. Animal feeds with a variety of bases can have palm fruit added. Animal feeds with a variety of bases, including palm fronds, can include a variety of other components added.
Processed palm fronds and palm fruit, such as dates, can be combined according to a variety of different ratios. For example, in some embodiments palm fronds and palm fruit can be combined according to a ratio by weight of approximately 80 pounds of processed palm fronds for each pound of palm fruit. In some embodiments, the ratio by weight of processed palm fronds to palm fruit can be greater than or equal to approximately 70 and/or less than or equal to approximately 90. In some embodiments, smaller ratios may be desired. For example, in some embodiments palm fronds and palm fruit can be combined according to a ratio by weight of approximately 8 pounds of processed palms fronds for each pound of palm fruit. In some embodiments, the ratio can be approximately 5 to 1, or even lower, such as approximately 2.5 to 1, 1 to 1, or less than 1 to 1. In some embodiments, palm fronds and palm fruit can be combined according to a ratio by weight of approximately 8 pounds of processed palm fronds for each 10 pounds of palm fruit. In some embodiments, this ratio can be approximately 5 pounds of processed palm fronds for each 10 pounds of palm fruit. In some embodiments, the ratio can be approximately 1 pound of processed palm fronds for each 10 pounds of palm fruit.
It may be desirable to express the ratio of a waste material (e.g., palm frond) to a binding agent (e.g., palm dates, grapes, raisins, apples, honey, etc.) as percentages of the total amount of waste material and binding agent. In some embodiments, the total amount of waste material and binding agent is about 90% waste material and about 10% binding agent by weight. In some embodiments, the proportion of waste material is between about 30% and 95% while the proportion of binding agent is between about 5% and 70% by weight. In some embodiments the proportion of waste material is between about 55% and 93% while the proportion of binding agent is between about 7% and 45% by weight. In some embodiments, the proportion of waste material is between about 75% and 91% of the proportion of binding agent is between about 9% and 25% by weight. These proportions may only describe the relationship between the waste material and binding agent. For example, if the proportion of waste material is 90% of the combination and proportion of binding agent is 10% by weight, the addition of other ingredients to the final byproduct (e.g., trophic additives, nutritional supplements, fill materials, fiber components, protein components, vegetable components, processing additives, scratch) may reduce the total proportion of waste material to be less than 90% and the total proportion of the binding agent to be less than 10%. However, it can be helpful to describe the proportions between the waste material and binding agent since this proportion may be influenced by the type of grinder available, the size of the screens used, the availability of waste materials and/or binding agent, the desired consistency, the desired palatability/taste of the waste byproduct, and/or any nutritional requirements of the waste byproduct.
In some embodiments, larger ratios may be desired. For example, in some embodiments palm fronds and palm fruit can be combined according to a ratio by weight of approximately 10 pounds of processed palms fronds for each pound of palm fruit. In some embodiments, the ratio can be approximately 12 to 1. In some embodiments, the ratio can be approximately 15 to 1, 20 to 1, or even larger, such as approximately 25 to 1 or greater in some embodiments.
In some embodiments, these ratios can be by volume instead of by weight. For example, a ratio by volume of 8 to 1 would indicate that a mixture of processed palm fronds and palm fruit was formed by mixing 8 scoops of processed palm fronds with 1 scoop of palm fruit. Preferably, in embodiments where processing machines are used, such as described further below, the ratio is such that the mixture is not too sticky to gum up or block the processing machine. In other embodiments, stickiness of the mixture is desirable and advantageous to produce a desired feed consistency and composition.
In some embodiments, nutritional additives can be added to the mixture to modify the desired nutritional content. For example, in some embodiments, urea can be combined with palm fronds and dates.

For example, in some embodiments an animal feed can include approximately 33% palm frond by weight, approximately 33% date or other fruit or sugar component by weight, and approximately 33% wheat or other grain component by weight. Thus, in some embodiments an animal feed can include weight-based ratios of palm frond to date to wheat of 1 to 1 to 1. In some embodiments, an animal feed can include weight-based ratios of palm frond to date to wheat of 0.8 to 1 to 0.8.

In some embodiments, the weight-based ratio of the combined weight of dates and wheat to palm frond can be between approximately 1:1 and approximately 3:1.
Dates and/or other palm fruit can be added to the palm fronds according to a variety of methods. In some embodiments, the dates can be diced, chopped, or crumbled and mixed in as such. In some embodiments the dates can be chopped into fine crystals, having a consistency roughly equivalent to sugar. In some embodiments, the dates can be liquefied and poured or sprayed onto the palm fronds. In some embodiments, a liquid, such as water, can be added to the dates to make them easier to pour, spray, and/or mix with the palm fronds. In some embodiments additional additives, such as the urea and/or wheat, can be mixed with the dates before being mixed with the palm fronds. In some embodiments, additional additives can be added to the palm fronds before or after the dates. In some embodiments, date (or other additive) and palm frond can be chopped and/or ground after the dates (or other additive) and palm fronds have been mixed together.
The mixtures described herein can produce a product that rivals or surpasses the nutritional content of current feeds. For example, in some embodiments a mixture can have a TDN content of approximately 55%. It can have an a crude protein content of approximately 15%, a crude fat content of approximately 2.7%, a crude fiber content of approximately 25%, and an ash content of approximately 12%. In some embodiments, additional minerals can be included, either through the urea or other additive, and the final result can have approximately 0.5% of minerals.
In some embodiments a mixture can have varying levels of a crude protein content. For example, in some embodiments a mixture can have a crude protein content that is greater than or equal to approximately 1% and/or less than or equal to approximately 10%. In some embodiments a mixture can have a crude protein content that is greater than or equal to approximately 2% and/or less than or equal to approximately 6%. In some aspects, one or more nutritional additives can be added such that the mixture can have a crude protein content that is greater than or equal to approximately 5% and/or less than or equal to approximately 30%. In some embodiments, a mixture can have a crude protein content that is greater than or equal to approximately 8% and/or less than or equal to approximately 15%. In some embodiments, a mixture can have a crude protein content that is greater than or equal to approximately 12% and/or less than or equal to approximately 15%. In some embodiments, a desired protein content can depend on the type of animal expected to eat the feed. For example, in some embodiments feed prepared for dairy cattle can have a crude protein content that is greater than or equal to approximately 10% and/or less than or equal to approximately 20%. In some embodiments, feed prepared for beef cattle can have a crude protein content that is greater than or equal to approximately 20% and/or less than or equal to approximately 30%.
Other nutritional content of mixtures described herein can similarly vary. For example, in some embodiments a mixture can have a TDN that is greater than or equal to approximately 45% and/or less than or equal to approximately 65%. In some embodiments a mixture can have a TDN that is greater than or equal to approximately 50% and/or less than or equal to approximately 60%. In some embodiments a mixture can have a TDN that is greater than or equal to approximately 60% and/or less than or equal to approximately 70%. In some embodiments a mixture can have a TDN that is greater than or equal to approximately 70% and/or less than or equal to approximately 80%. The unexpectedly high value of the TDN of the sweet palm hay is easy to digest, results in fast weight gain and imparts glossy coats. Another unexpected result is that animals fed a diet of sweet palm hay produce a limited-odor and/or odorless manure because the sweet palm hay is thoroughly digested in the gut of the animal. The limited-odor and/or odorless manure produced by animals fed upon sweet palm hay limits and/or does not attract flies or other insects or pests.
In some embodiments a mixture can have a crude fat content that can be greater than or equal to approximately 2% and/or less than or equal to approximately 8%. In some embodiments a mixture can have a crude fat content that can be greater than or equal to approximately 2% and/or less than or equal to approximately 5%.
Similarly, in some embodiments a mixture can have a fiber content that can be greater than or equal to approximately 15% and/or less than or equal to approximately 45%. In some embodiments, a mixture can have a fiber content that can be greater than or equal to approximately 20% and/or less than or equal to approximately 30%.
The ash content in some embodiments can be greater than or equal to 4% and/or less than or equal to 17%. In some embodiments, the ash content can be greater than or equal to approximately 8% and/or less than or equal to approximately 12%. In some embodiments laws may limit the ash content that can be in the feed, and the ash content can be capped at a legal limit, for example at 12%. The amount of minerals and/or additives can in some embodiments be greater than or equal to approximately 0.2% and/or less than or equal to approximately 1%.
The use of any type of palm frond is contemplated. For example, Washington Robustas (Mexican Fan Palms), Washingtonia Filiferas (California Fan Palms), Phoenix Canariensis (Canary Island Date Palms), Phoenix Dactylifera (Date Palms), or any other date or oil palm can be used. Similarly, any type of date can be used. For example, a Deglet Noor palm, or a Canary Palm can be used. The dates may include the skin, the flesh, and/or pits of the fruit. Preferably, the dates are allowed to dry until they have a moisture content less than or equal to approximately 10%. In some embodiments, a moisture content of the dates is greater than or equal to approximately 5% and/or less than or equal to approximately 12%. In some embodiments, a moisture content greater than or equal to approximately 3% and/or less than or equal to approximately 15% can be used. In some embodiments, a moisture content greater than or equal to approximately 4% and/or less than or equal to approximately 8% can be used. In some embodiments the moisture content can exceed 10%. In some embodiments, the dates are dried to a moisture content of less than about 11%. In some embodiments, other fruits or materials besides dates can be used. For example, palm seeds or other types of palm fruit, such as oil palm berries, can be used instead of or in addition to dates. These alternative fruit or fruit mixtures can be combined with palm fronds and/or other additives such as urea and/or wheat according to the various ratios described herein.
Palm fronds can be tough, and general processing used for other types of feed bases, such as alfalfa, to prepare for use in feeds may be insufficient or too expensive for palm fronds. For example, placing raw palm fronds into a tub grinder may not produce palm fronds that are sufficiently chopped to be used in feeds. Additionally, raw palm fronds are generally too wet to be thrown directly into a tub grinder or other grinding or chopping machine. A variety of processes can be used to put the palm fronds into a form suitable for feed before combining them with dates or other products.
Preferably, the fronds are allowed to dry until they have a moisture content greater than or equal to approximately 1% and/or less than or equal to approximately 15% In some embodiments, palm fronds with a moisture content greater than or equal to approximately 10% and/or less than or equal to approximately 20% can be used. In some embodiments, a moisture content greater than or equal to approximately 5% and/or less than or equal to approximately 15% can be used. In some embodiments, a moisture content greater than or equal to approximately 1% and/or less than or equal to approximately 10% can be used. In some embodiments, a moisture content greater than or equal to approximately 1% and/or less than or equal to approximately 25% can be used. In some embodiments the moisture content can exceed 25%.
Once the palm fronds have reached a desired moisture content, for example between about 1% and 15%, they can be mixed with the raw dates and processed according to a variety of methods. In some embodiments, the palm fronds and date mixture can be fed through a grinder. As an example, a grinder sold under the brand name Vermeer can be used to grind the palm fronds and date mixture. In some embodiments, the grinder is equipped with a screen having openings greater than or equal to approximately 0.1 inch and/or less than or equal to approximately 2 inches. In some embodiments, the screen has openings of less than approximately 1 inch. In some embodiments, the openings are of less than approximately 0.8 inch. In some embodiments, the openings are of less than approximately 0.6 inch. In some embodiments, the grinder is equipped with a screen having openings greater than or equal to approximately 0.2 inch and/or less than or equal to approximately 0.7 inch. In some embodiments, the screen has openings of less than approximately 0.5 inch. In some embodiments, the openings are of less than approximately 0.4 inch. In some embodiments, the openings are of less than approximately 0.3 inch.
Once the palm fronds and date mixture have been ground and screened, a trommel screen can be used to sort the palm fronds and date mixture into two piles: finer pieces and longer pieces. As an example, a trommel sold under the brand name Vermeer can be used. One embodiment of this method of processing palm fronds and dates with a grinder is illustrated in
The processed palm fronds and date sweet palm hay can form a base product that can be combined according to the various mixtures described herein, forming an animal feed. In some embodiments, various mixtures, such as mixtures described herein, can be formed within a grinder. Thus, for example, in some embodiments palm fruit and/or other additives can be added with the palm fronds into the grinder.
Once a desired formulation has been achieved, the products can be prepared for use according to a variety of manners. In some embodiments, the feed can be left loose as initially mixed. In some embodiments, the feed can be baled or packaged. In some embodiments, baling or packaging can be done after feed has been processed. One advantage of mixing dates into the palm fronds is that the palm frond powder can help provide a binding function, making it easier to grind the sticky dates. It is understood that “hay” is a broad term and are used in its ordinary sense in this application, including, for example, to refer broadly to a dried and cut herbage which is used for fodder. Similarly, “cube” is a broad term and is used in its ordinary sense in this application, including, for example, to refer broadly to a compressed feed mixture. References to a cubed shape can refer to a generally square or rectangular shape or to having a generally square or rectangular shaped cross section, but other shapes and cross sections are possible and contemplated, such as, for example, pellets and/or generally cylindrical shapes and/or shapes with a circular or rounded cross section. Cubed feed may have one or more sides or dimensions that are longer than one or more of the other sides or dimensions. In some embodiments, different cubes within a batch of cubed feed may have different dimensions from other cubes within the batch. Additionally, the cubes do not necessarily have defined shapes, sides, edges or corners.
In some embodiments cubes or other forms of compressed feed can be formed with a feed compressing machine, such as a cubing machine or an extruder (e.g., pelletizer). In some embodiments, the machine can include a grinder that can mix and/or grind the components. In such embodiments, the grinder of the feed compressing machine can be used in addition to or instead of a grinder during the process described with respect to
In some embodiments, a mixture can be passed through a filter, such as a screen or strainer, after it goes through a grinder, whether a first grinder and/or a grinder associated with a feed compressing machine. This can help remove large pieces and hard pieces that might not grind up, such as pits of dates. In some embodiments, a mixture can pass through multiple filters. For example, a grinder may include a filter, and it may be desirable to pass the ground material through a second filter before it goes into the grinder or after it comes out of the grinder.
Cubing the feed can present a variety of advantages. For example, cubed feed can be generally easier and more efficient to ship and/or store. As a further example, because cubes can be compressed when formed, they can have a greater density than loose feed allowing for more feed by mass to fit within the same volume. In some embodiments, cubes can be shipped and/or stored in large containers, such as sacks, boxes, or other containers. In some embodiments, containers can be sized to hold 1000 lbs of cubed feed. In some embodiments they can hold more or less. In some embodiments, cubes can be stored and/or shipped loosely.
Cubing the feed can also extend the shelf life of the feed. For example, in some embodiments loose feed might be good for about a year. Cubed feed can be good for significantly longer. In some embodiments, packaging loose feed or cubed feed can also extend the shelf life of the feed.
In some embodiments, a base feed can be passed through a mill to collect scrap material left in the mill that can be added to the feed. For example, in some embodiments a base feed including a mixture of palm fronds and palm fruit, such as dates, can be fed through a mill that had previously been used to process or transport a first, different feed product. The scraps of the first feed product that remain within the mill (referred to as the “mill run”) can be picked up by the base feed and mixed in with it as an additive. For example, a palm frond and palm fruit mixture can be passed through a mill that had previously had wheat or other grains pass through, such as sorghum, milo, corn, etc. The mill run can act as an additive to the palm frond and palm fruit mixture and can add a protein component to the mixture. In some embodiments, this can provide a desired nutritional content for the resulting feed and can also serve to clean the mill run from the various components of the mill, such as tanks, flues, and/or chutes. This can help minimize and/or eliminate cleaning costs that would otherwise be incurred. In some embodiments, the addition of a palm fruit to a base feed passed through the mill can help collect mill run by helping the base feed to adhere to the mill run.

Systems and methods for processing, recycling, repurposing, and/or disposing of organic waste material can take on a number of forms. In some embodiments, the systems and methods can include introducing a combination of waste material and flesh of fruits into a grinder. This combination can be ground into chunks having a first diameter. In some embodiments these chunks can be introduced into a grinder to be ground into chunks having a second diameter. In some embodiments the waste material has a moisture content below the first maximum moisture content. In some embodiments the flesh of fruits has a moisture content below a second maximum moisture content. Ensuring that the waste material has a moisture content below the first maximum moisture content can support the efficient grinding of the waste material. For example, if the moisture content of the waste material is too high, attempting to grind the waste material may slow down the grinding process, damage the grinder, and/or create undesired consistency. The moisture content of the waste material can also support a desired consistency and/or nutritional content of the byproduct. Similarly, maintaining a moisture content of the flesh of fruits below the second maximum moisture content can provide the proper consistency of the ground chunk byproduct. In some embodiments, the flesh of fruits serves as a binding agent that provides the desired consistency of byproduct.
In some embodiments the flesh of fruits comprises one or more sweet fruits and/or vegetables, such as, for example, dates, peaches, apples, strawberries, citrus fruits, oranges, grapefruits, lemons, grapes, raisins, etc. In some embodiments the waste material comprises palm fronds.
The ratio of waste material to the flesh of fruits can be helpful in creating a desired consistency and/or maintaining the speed of production. The ratio may also be influenced, for example, by the availability of the waste material and or flesh of fruits, the geographic region, the cost of supplies, the availability of transportation or other resources, the desired nutritional content, etc.
In some embodiments, the combination of the waste material in the flesh of the fruits is introduced into the grinder at a ratio of between about 6:1 and 14:1 by volume. In some embodiments this ratio can be between about 5:3 and 4:1 by volume. In certain embodiments, this ratio is between about 15:1 and 20:1 by volume.
The ratios of waste material to the flesh of fruits can also be measured by weight. For example, in some embodiments, combination of the waste material and flesh of fruits is introduced into the grinder at a ratio between about 5:1 and 10:1 by weight. In some embodiments this ratio can be between about 3:2 and 3:1 by volume. In certain embodiments, this ratio is between about 12:1 and 18:1 by volume.
In some embodiments, the method of disposing of green waste further comprises arranging for the waste material to dry until the waste material reaches a moisture content below the first maximum moisture content. Arranging for the waste material to dry to a certain level of moisture content can take a number of different forms. For example, in some embodiments arranging for the waste material to dry includes allowing the waste material to dry for a period of time. The period of time can range from five hours to five weeks. In some embodiments, the period of time is between about one day and 15 days. Arranging for the waste material to dry can include allowing the waste material to dry in a windy area, in a dry climate, and/or in an oven. In such embodiments, the period of time to dry the waste material may be reduced. In some embodiments, arranging for the waste material to dry includes allowing and/or directing a third party to dry the waste material. In some embodiments, arranging for the waste material to dry occurs before the waste material is combined with the flesh of fruits. In other embodiments, the step occurs after the waste material is combined with the flesh of fruits but before being introduced into the grinder. In yet other embodiments, the step occurs after being ground a first time.
The method of processing and/or disposing of green waste can also comprise arranging for flesh of the fruits to dry until the flesh of the fruit reaches a moisture content below the second maximum moisture content. Arranging for the flesh of fruits to try can also take a number of different forms. In some embodiments, arranging for the flesh of fruits to dry includes allowing the flesh of fruits to dry for a period of time. The period of time can range from 2 hours to 5 weeks or longer. In some embodiments, the period of time is between about 2 days and 18 days. In some embodiments, the period of time to dry the flesh of fruits can be reduced by, for example, using a heater, oven, and/or fan.
Various types of preprocessing may take place before the waste material and/or flesh of fruits is introduced into the grinder. Preprocessing can include chopping, shredding, grinding, and/or any other processing or significant alteration of the waste material and/or flesh of fruits. Preprocessing can refer to processing that occurs while the waste material contains a moisture content below the first maximum moisture content and/or while the flesh of fruits contains a moisture content below the second maximum moisture content. In some embodiments preprocessing comprises chopping the waste material to a length shorter than a maximum length. In some embodiments the maximum length is about 8 inches. In some embodiments, the maximum length is between about 3 inches and 7 inches. In some embodiments, the maximum length is between 6 inches and 12 inches.
In some embodiments the ground chunk comprises a greater proportion of waste material then flesh of fruits by weight. Some considerations for what proportion of waste material is used within the ground chunk are already described above, such as the desired consistency. As a further example, in certain circumstances it is advantageous to create a byproduct that has a certain nutritional content for humans and/or other animals. In some embodiments, the ground chunk comprises between about 60% and 80% waste material by weight. In certain embodiments, the ground chunk comprises between about 45% and 75% waste material by weight. In some embodiments, the ground chunk comprises more than 80% waste material by weight.
Some embodiments of the method include further processing or post-processing. Such post-processing may result in turning the ground chunk into a resulting byproduct. In some embodiments, post-processing comprises mixing in one or more additives. Such additives may include, for example, roughening additives, calcium additives, “scratch”, protein additives, fat additives, nutritional additives, mineral additives, vitamin additives, emulsifiers, sweetening additives, grain and/or cereal additives, binding agents, flavor additives, and/or preservatives may be added during post-processing. In some embodiments, these additives may be introduced into the grinder before and/or with the waste material and/or the flesh of fruits.
Post-processing may include shaping the resulting byproduct. In some embodiments, post-processing includes forming the resulting byproduct into the pellet. Pellet can refer to a variety of shapes and sizes, including those mentioned above. For example, pellets can comprise cubes, clumps, balls, chunks, and/or bits. In some embodiments, post-processing comprises forming the resulting byproduct into wafers, crumbles, sludge, briquettes, and/or blocks. The type of post-processing that is used may be determined by the desired use of the resulting byproduct. For example, in some embodiments the resulting byproduct is used as an animal feed, including feed for livestock, poultry, cattle, etc. Certain embodiments allow for the resulting byproduct to serve as a biofuel, structural support, fertilizer, mulch, cleaning agent, lubricant, and/or roughage.
A variety of systems, methods, and products, including byproducts from processing, recycling, and/or disposal of waste materials can be obtained through a number of methods and/or systems disclosed herein. For example, some methods, products, and systems can be found in U.S. Patent Publication No. 2014/0234524, filed Mar. 11, 2013, U.S. Patent Publication No. 2016/0007630, filed Aug. 9, 2015, and International Patent Application No. PCT/US2017/024011, filed on Mar. 24, 2017, the entire contents of each of which are incorporated by reference herein and made a part of this specification.
In some embodiments, a byproduct comprises a ground chunk having a diameter less than a maximum diameter. In some embodiments, the maximum diameter is between about 1 inch and 5 inches. In other embodiments the maximum diameter is between about 0.2 inches and 1 inch. In some embodiments, the maximum diameter is less than 0.2 inches. In some embodiments, the maximum diameter is between about 2 inches and 8 inches. As used herein, in some embodiments, the term diameter can be used with reference to a length dimension, a width dimension, and/or a thickness dimension as would be understood by one of skill in the art in view of the entire disclosure relied upon herein. The ground chunk can be comprised of waste material and of flesh of fruits. In some embodiments the waste material comprises palm fronds. The types of fruits used can include sweet fruits, for example, palm dates, peaches, apples, strawberries, citrus fruits, oranges, grapefruits, lemons, grapes, raisins, etc. The flesh of the fruits can provide a binding function with the waste material. In certain embodiments the waste material has a moisture content below the first maximum moisture content. In some embodiments the flesh of the fruits has a moisture content below a second maximum moisture content. In some embodiments the first maximum moisture content is between about 5% and 15% by weight. In some embodiments the first maximum moisture content is between about 10% and 20% by weight. In certain embodiments, it is advantageous to maintain a low moisture content of the waste material to increase the ease of and/or reduce the energy used for chopping, shredding, grinding, and or otherwise processing the waste material.
In some embodiments the second maximum moisture content is between about 5% 15% by weight. In certain embodiments the second maximum moisture content is between about 10% and 20% by weight. In some embodiments the second maximum moisture content is between about 18% and 34%. The second maximum moisture content may depend at least in part on a variety of factors, including, for example, the available power output of the machine, the ratio of waste material to the flesh of fruits, the desired consistency of the ground chunk, the desired nutritional content of the ground chunk, the shape and/or size of the screen openings through which the ground chunks are moved during, for example, the grinding process, and/or the volume of waste material and/or flesh of fruits to be processed. The term “processing” may include chopping, shredding, grinding, adding or removing ingredients, and/or any other significant alteration of the waste material, flesh of fruits, and/or ground chunk.
The ground chunk can further comprise various additives. The additive(s) used may depend at least in part on the availability, desired nutritional content, taste characteristics, and/or cost of the additive. In some embodiments, an additive is added after the ground chunk has been ground at least once. In some embodiments, the additive is added together into a grinder with the waste material and flesh of fruits before being ground.
For example a roughening additive can be added to the ground chunk. The roughening additive can comprise one or more grains. For example the roughening additive may comprise wheat, buckwheat, milo, alfalfa, soy, corn, hay, oats, rice, barley, rye, millet, sorghum, quinoa, grass, etc.
Some embodiments include other additives, such as a calcium additive. The calcium additive comprises calcium but may include other nutritional and or functional properties as well. The calcium additive may comprise one or more ingredients, such as, for example, oyster shell, a salt comprising calcium or a calcium derivative, calcium carbonate, limestone, calcium monophosphate, calcium diphosphate, and/or egg shells.
Other additives are included in some embodiments. For example, one or more nutritional additives are added to the byproducts in certain embodiments to create a resulting byproduct. Some examples of nutritional embodiments include almond shells, walnut husks, peanut shells, fruit pits, cotton seed, corn, brewer's grain, distiller's grain, potatoes, lettuce, tomatoes, soy, turnips, fruit rind, and beet pulp. In some embodiments, sugar beets, sugar cane, peaches, apples, strawberries, citrus fruits, oranges, grapefruit, lemons, grapes, and/or raisins are added.
After the palm fronds have been collected and optionally dried, palm fronds are placed in a first grinder 1108 to be ground to a first length and/or diameter. The first grinder 1108 is outfitted with a first screen having holes with a first diameter. These holes will help ensure that only palm fronds having a first maximum length and/or diameter pass through the grinder 1108. Because palm fronds can be difficult to grind using traditional methods, grinding the palm fronds the first time at a larger first length and/or diameter before grinding them a second time at a smaller length and/or diameter has proven to be effective. The diameter of the holes in the first screen 1108 may be between about 1 to 3 inches, preferably around 2 inches. In some embodiments the first grinder is manufactured by Vermeer. Optionally the first screen may be outfitted with a baffle to help minimize the number of particles (e.g., fibers) of palm frond with a length and/or diameter greater than the first maximum length and/or diameter that pass through the first screen 1108. The baffles are discussed in more detail below.
Once the palm fronds have been ground a first time, they may a second grinder 1112. The second grinder 1112 may be different from the first grinder 1108. Alternatively, the second grinder 1112 is the same as the first grinder 1112 except that the first screen has been replaced with a second screen. The second screen, regardless if it is on the first grinder or on the second grinder, has holes having a second length and/or diameter. The holes in the second screen will help ensure that only palm frond particles having a second maximum length and/or diameter will pass through the second grinder 1112. The second screen may be outfitted with a baffle, as with the first screen, to help ensure that no particles having a length and/or diameter greater than the second maximum length and/or diameter pass through the second grinder 1112. The second maximum length and/or diameter may be between about ⅛ inch and about 1½ inches and is preferably between about ¼ inch and about ¾ inch. While smaller particle sizes help in later parts of the system (e.g., with mixing, pelletizing), it also creates challenges in throughput and/or efficiency of the grinder 1112. In particular, too small of a second maximum length and/or diameter can create clogging and/or backlog problems in the disposal system, as more fully described below. In some embodiments, a suitable second maximum length and/or diameter is ½ inch. Other lengths and/or diameters are also workable. The first and/or second screen may be curved and/or flat but are preferably curved.
It may be desirable to create a usable and/or appetizing byproduct from the organic waste that has been collected. The palm fronds that have been ground a second time to a second maximum length and/or diameter are mixed with other materials in a mixer 1116. These materials may include grains, nutritional supplements, roughening additives, fruits (e.g., dates), binding agents (e.g., canola), fill material, and/or other additives. The mixer 1116 may stir, shake, knead, compress, rotate, and/or blend the ingredients together to form a mixture. The mixture may be as described elsewhere herein. In some embodiments, the mixture comprises a base feed. Ingredients may be added according to prescribed ratios and/or percentages (e.g., by weight, by volume) described elsewhere herein. Additionally, the ingredients and their proportions may be selected in such a way as to achieve a target nutritional content. For example, the waste byproduct may be used as an animal feed for certain types of animals with particular nutritional needs. These nutritional needs may vary by animal.
With continued reference to
The pelletizer (e.g., pellet mill) 1120 heats the mixture up to a minimum temperature in order to pass the mixture through the holes. The minimum temperature may depend on the formulation of the mixture that is used. In some embodiments, the pelletizer uses steam to achieve the minimum temperature and/or to serve as a binding agent for the mixture. The steam may also be used to lubricate the mixture as it passes through the holes. To prevent overheating of the pelletizer 1120 or pelletizer parts, some embodiments include a cooler that reduces the temperature of the plate. The cooler may also be used to cool down the mixture after it has exited the holes. In some embodiments, the plate comprises a thermally insulating material (e.g., wood, plastic) that does not require a cooler for its operation. The plate may also comprise a layer of metal having a thickness configured to dissipate heat rapidly enough to minimize or negate the need for a cooler. Optionally, the pelletizer cuts the mixture into particular lengths of pellets. However, in some embodiments, the mixture is allowed to freely exit the plate and break off due to its own weight, thus creating a range of pellet lengths.
The palm material 1204 is sent to a first palm grinder 1212. The palm may be allowed and/or forced to pass through one or more first screens having holes with a first length and/or diameter. Thus, the resulting first palm particles may have a first maximum length and/or diameter determined by the diameter of the holes in the first screens. The first maximum length and/or diameter of the first palm particles may be between 0.8 inches and 4.5 inches. The maximum length and/or diameter may be about 3 inches. In some embodiments, the first maximum length and/or diameter of the first palm particles is between 1.4 inches and 2.7 inches. In some embodiments, the first maximum length and/or diameter is about 2 inches. In some embodiments the first palm grinder is manufactured by Vermeer. The first screen may be outfitted with a baffle to help ensure that palm frond particles with a length and/or diameter greater than the first maximum length and/or diameter do not pass through the first screen. Such a screen with a baffle is described in more detail below.
The resulting first palm particles may be sorted by a trommel screen 1216. The trommel screen may include a rotor to move particles from one end of the trommel screen to another. As the particles move to the end of the trommel screen 1216, some of the smaller palm grinding's may be filtered out. The trommel screen 1216 may comprise a screen having openings with a maximum size smaller than the diameter of the holes in the first screens. This will permit relatively larger palm particles to pass through to a second grinding while the smaller palm particles can bypass the second grinding. This improves efficiency of the system 1200 because only the particles that need to be ground a second time will go through the second grinding, thus freeing up space, power, and other resources for use in the system 1200. In some embodiments, the maximum size of the openings in the trommel screen 1216 may be comparable to the size of the holes in the second palm grinder 1228. For example, the openings may be between 0.1 inches and about 0.9 inches in diameter. In certain embodiments, some of the resulting palm particles may later be used for palm hay 1224. The palm hay may undergo further processing and/or treatment in the system 1200. Alternatively, it may undergo different processing not shown here.
The trommel screen 1216 may be physically situated between the first palm grinder and the second palm grinder so that the first grinder 1212, first sorting 1216, and second grinding 1228 may automatically and smoothly move palm particles from one system element to the next without significant human intervention. For example, conveyor belts, rotors, and/or hoppers may be included to facilitate the movement of the palm particles.
Some of the resulting particles can be useful for various aspects. For example, some particles may be somewhat larger and may be useful in the creation of palm hay, as described in more detail herein. Relatively larger palm particles that do not exit the trommel screen 1216 as smaller palm grindings 1220 or palm hay 1224 may be referred to as the first sorted palm particles. The first sorted palm particles may enter a second grinder 1228. A second grinder different 1228 from the first palm grinder 1212 may be used. Alternatively, the second palm grinder 1228 may comprise the first palm grinder 1212 where the first screens have been switched out with different screens. The second screens (e.g., the screens of the second palm grinder), regardless if they are on the first grinder or on a separate second grinder, have holes having a second diameter. The holes in the second screen will help ensure that only palm frond particles having a second maximum length and/or diameter pass through the second palm grinder 1228. The second screens may be outfitted with baffles, as with the first screens, to help ensure that no particles having a length and/or diameter greater than the second maximum length and/or diameter pass through the second grinder. The diameter of the holes in the second screens may be between about 1/16 inch and about 15/16 inch and is preferably between about ¼ inch and about ¾ inch. In some embodiments, the diameter is about ½ inch. Holes of ½ inch can help prevent clogging and/or backlog problems in the disposal system 1200 while allowing proper mixing of the palm with other additives, as more fully described below.
The resulting second palm particles may optionally gather in a storage bin 1232. The storage bin may comprise a hopper. The storage bin may simply be an area on the floor. The storage bin 1232 also includes any particles 1220 that bypassed the second palm grinder 1232. The palm particles are sent into a mixer 1264. The mixer 1264 also receives other ingredients, such as a grain (or cereal) 1236, a roughening additive 1240, a binding agent 1244, and/or any other additive as described herein. Also added to the mixer are the ground dates.
As part of the example waste disposal system 1200, dates 1248 are dried in a date dryer 1252. The dryer 1252 may comprise sun-drying, wind drying, spin drying, tumble drying, heat drying, and/or air drying. In some cases, the dates are allowed to air dry and/or sun dry for at least a day, preferably at least a week. The dates are dried to a moisture content below a second maximum moisture content by weight. In some embodiments the second maximum moisture content is between about 0.5% and 35% by weight. In certain embodiments the second maximum moisture content is between about 3% and 20% by weight. Preferably, the second maximum moisture content is between about 5% and 16%. The second maximum moisture content may depend at least in part on a variety of factors, including, for example, the available power output of the system and system components, the ratio of waste material to the flesh of fruits, the desired consistency of the dates, the desired nutritional content of the finished byproduct 1296, the shape and/or size of the screen openings through which the date particles are moved during, for example, the milling process, and/or the volume of waste material and/or flesh of fruits to be processed.
Once the dates 1248 reach a moisture content of at most the second maximum moisture content, the dates are moved into a hammer mill 1256. The hammer mill 1256 grinds the dates into smaller particles. The hammer mill 1256 may alternately be referred to as a grinder. In some embodiments, the dates are pulverized by the hammer mill. The dates may include the skin, the flesh, and/or pits of the fruit. The hammer mill may be equipped with screens with optional baffles. The screens and/or baffles may be similar to those in the first palm grinder and/or second palm grinder. The screens may have holes with a maximum diameter. The maximum diameter may be between about 0.05 inch and about 1 inch and is preferably between about 0.2 inch and about 0.6 inch. The resulting date particles may be stored in a storage bin 1260 or other storage area until needed. The date particles may then be mixed with the palm material 1204 and, optionally, other ingredients described herein.
The mixer 1264 mixes the palm material 1204 (e.g., resulting second palm particles) and the dates 1248 (e.g., the resulting date particles) and, optionally, other ingredients (e.g., grain 1236, roughening additive 1240, binding agent 1244). This creates an edible foodstuff that may undergo further processing. The mixer may mix ratios among palm, dates, grain (e.g., wheat, corn), and/or nutritional additive as described herein. The mixture may contain between about 7% and 88% palm by weight. In some embodiments, the mixture contains between about 18% and 70% palm by weight. In some embodiments, the mixture contains between about 25% and 45% palm by weight. In some embodiments, the mixture contains between about 36% and 92% palm by weight. The amount of palm may be determined by the amount of nutritional content desired, the amount of palm available, and/or other factors.
The mixer 1264 may mix dates into the mixture at a by-weight percentage of between about 4% and 59% date. In some embodiments, the mixture contains between about 12% and 27% dates by weight. In some embodiments, the mixture contains between about 8% and 22% dates by weight. In some embodiments, the mixture contains between about 15% and 45% dates by weight. It may be desirable to include at least 30% dates by weight.
One or more binding agents 1244 may be added to the mixture. Binding agents may include dates or other fruits, canola oil, peanut oil, corn syrup, soybean oil, palm oil, coconut oil, sunflower oil, water, egg, alcohol, gelatin, agar, flax meal, butter, tapioca, vegetable puree, honey, agave, xanthan gum, and/or any other edible binder. For example, in some embodiments the binding agent comprises canola oil and is included at about 22% by weight of the total mixture. The mixture may contain between about between about 15% and 92% binding agent by weight. In some embodiments, the mixture contains between about 19% and 78% binding agent by weight. In some embodiments, the mixture contains between about 25% and 65% binding agent by weight. In some embodiments, the mixture contains between about 20% and 35% binding agent by weight. A binding agent may not only help keep the ingredients together, but it can add nutritional content to the final product. The binding agent may add a particular flavor and/or texture that animals prefer. The amount of binding agent included in the mixture may depend in part on the proportion of palm included in the mixture, the proportion of dates in the mixture, and/or proportion of other ingredients.
A roughening additive 1240 may be included in the mixture. A roughening additive may provide an animal with appropriate fiber and other nutrients. The roughening additive 1240 can comprise palm but may include one or more grains. For example the roughening additive may include wheat, buckwheat, milo, alfalfa, soy, corn, hay, oats, rice, barley, rye, millet, sorghum, quinoa, and/or grass. The mixture may contain between about between about 2% and 57% roughening additive by weight. In some embodiments, the mixture contains between about 4% and 25% roughening additive by weight. In some embodiments, the mixture contains between about 1% and 15% roughening additive by weight. In some embodiments, the mixture contains between about 8% and 20% roughening additive by weight. A common roughening additive is wheat, but other additives may be used. For example, in some embodiments, the roughening additive comprises about 12% of the mixture by weight. The mixture may include a greater proportion of roughening additive for poultry feeds.
A grain 1236 may be included in the mixture as well. The grain 1236 may be included as part of the roughening additive 1240 or it may not be. A common grain 1236 for animal feeds is rice, but wheat and corn are also used in many embodiments. For example, in some embodiments, the mixture includes about 5% rice by weight. Other grains include buckwheat, milo, alfalfa, soy, hay, oats, barley, rye, millet, sorghum, quinoa, and/or grass. The mixture may contain between about between about 1% and 24% grains by weight. In some embodiments, the mixture contains between about 3% and 16% grains by weight. In some embodiments, the mixture contains between about 8% and 20% grains by weight. In some embodiments, the mixture contains between about 10% and 85% grains by weight.
Other additives (not shown) may be added to the mixture as well. For example, calcium additives, “scratch”, protein additives, fat additives, nutritional additives, mineral additives, vitamin additives, emulsifiers, sweetening additives, flavor additives, and/or preservatives can be added. For example, in some embodiments of chicken feed, scratch is added to the feed to improve feed effectiveness. Some embodiments of chicken feed, as another example, include calcium additives (e.g., oyster shell, a salt comprising calcium or a calcium derivative, calcium carbonate, limestone, calcium monophosphate, calcium diphosphate, and/or egg shells). The calcium additive may comprise calcium but may include other nutritional and or functional properties as well. This may apply to each of the ingredients above. In other words, a particular ingredient or additive may appropriately fall into more than one category.
The mixture may optionally pass from the mixer into a first hopper 1268. The hopper 1268 may be functionally designed to prevent logjams in the flow of the system 1200. For example, the first hopper 1268 may use curved chutes to prevent material from getting jammed in corners of the chutes.
In some embodiments, the first hopper feeds the mixture into a hammer mill 1272. The hammer mill 1272 grinds the mixture into smaller particles. The milled mixture may be referred to as crumbles, chunks, powder, fine particles, particulates, beads, cubes, and/or pellets (even before being “pelletized”). In some embodiments, the mixture is pulverized by the hammer mill 1272. Like the hammer mill 1256, the hammer mill 1272 may be equipped with screens with optional baffles. The screens and/or baffles may be similar to those in the hammer mill 1256. The screens may have holes with a maximum diameter. The maximum diameter may be between about 0.05 inch and about 1 inch and is preferably between about 0.2 inch and about 0.6 inch. The resulting mixture particles may be passed to a second hopper 1276. Like the first hopper 1268, the second hopper 1276 may be configured to facilitate the flow of material through it and to avoid a blockage.
Once the mixture particles exit the hopper, they enter the pelletizer 1280. The pelletizer can make the feed more accessible and/or appetizing to animals. The pelletizer may include a pellet mill and/or other machine. Generally, the mixture is heated and forced through a plate with holes Like the plate in
The pelletizer 1280 heats the mixture up to a minimum temperature in order to pass the mixture through the holes. The minimum temperature may depend on the formulation of the mixture that is used. Like the pelletizer in
The pelletizer 1280 may optionally send the finished pellets to a bagger 1288. The bagger 1288 fills one or more bags with the pellets and then sends the bagged pellets to a wrapper 1292, which separates the bagged pellets into separate packages of product. The finished byproduct 1296 can be used as animal feed, erosion protection, bait, fill material, and/or sandbagging.
With reference to
As mentioned above, the baffle 1424 may include one or more baffle strips (not shown in
In some embodiments, the baffle may include a piece (e.g., strip) of metal welded across the length of the back of the screen, so that the baffle covers a portion of one or more holes 1408. In some embodiments, the baffle does not cover a center of the hole 1408. The baffle strips may cover a certain percentage of the area of one or more of the plurality of holes 1408. For example, the baffle may cover between about 5% and 70% of each hole of at least one or more of the plurality of holes 1408. In some embodiments, the baffle may cover between about 10% and 55% of each hole of at least one or more of the plurality of holes 1408. Preferably, the baffle strips cover between about 15% and 45% of each hole of at least one or more of the plurality of holes 1408. The baffle strips may be welded parallel to an orientation of a row of adjacent holes such that the baffles trip may be able to cover approximately the same amount of each adjacent hole. The baffle strips may be disposed on an interior side (e.g., the grinding side) of the screens 1416. Additionally or alternatively, the baffle strips may be disposed on an exterior side (e.g., the exit side) of the screens 1416. In some embodiments, the baffles may be alternated on the interior side and the exterior side of the screens 1416. The baffles may be associated with screens on one or more of the first and second grinders disclosed herein (e.g., the first palm grinder 1212 and/or the second palm grinder 1228 of
