Description
FIELD OF THE TECHNOLOGY

The technology disclosed herein generally relates to animal feed. More particularly, the technology disclosed herein related to an animal feed products and methods.


BACKGROUND

The wild and domestic animal feed industry has evolved to provide foods that can diverge from the natural or preferred diets of the target animals. For example, various types of bird feed incorporates a binding agent to prevent the particulates, such as seeds and insects, from dispersing in response to environmental elements such as rain and wind. Some bird feed incorporates gelatin as a binding agent to bind seeds (and other constituents) together, even though gelatin is not a natural food for wild or domesticated birds. Furthermore, the use of gelatin can slow down the manufacturing process for such feed because many hours are needed to wait for the gelatin in the product to dry. And within that drying period, water has hydrated the otherwise dehydrated constituents, which can become a breeding ground for contamination like bacteria and insects.


Some other types of animal feed incorporate suet as a binding agent for seed and other constituents. Suet is rendered fat that is frequently from cattle, and is not necessarily a desirable ingredient for some animals to consume at least in part because of its high fat content and low nutritional value.


SUMMARY

Some embodiments of the current technology relate to an animal feed product. The animal feed product has a container defining a cavity. A feed mixture is disposed in the cavity. The feed mixture is a plurality of animal feed particles and seed butter coating each of the plurality of animal feed particles. The animal feed particles is at least a plurality of seeds. The seed butter coating each of the plurality of animal feed particles is no more than 20% of the feed mixture by weight. A removable cover is coupled to the container over the cavity to encase the feed mixture.


In some embodiments, the animal feed particles also include a plurality of dehydrated invertebrates and/or a plurality of dehydrated insects. The plurality of dehydrated invertebrates can include mealworms and/or black soldier fly larvae. Additionally or alternatively, the plurality of seeds can include sunflower, grain, legume, and/or grass seeds. Additionally or alternatively, the seed butter includes sunflower seed butter. Additionally or alternatively, the seed butter contains peanuts, tree nuts, soybeans and/or pulses. Additionally or alternatively, the container is paper.

DETAILED DESCRIPTION


FIG. 1 depicts a perspective view of one example animal feed product 100 consistent with the technology disclosed herein, and FIG. 2 depicts a cross-sectional view of the animal feed product depicted in FIG. 1. The animal feed product 100 generally has a container 110 defining a cavity 120, a feed mixture 130 disposed in the cavity 120, and a removable cover 140 coupled to the container 110 over the cavity 120 to encase the feed mixture 130.


The feed mixture 130 generally is a plurality of animal feed particles 132 and a seed butter 134 coating each of the plurality of animal feed particles 132. The animal feed particles 132 are generally particles of food for a particular animal, such as birds. The animal feed particles 132 can have a number of different constituents, but generally will at least have a plurality of seeds. The plurality of seeds can be whole seeds and/or partial seeds. In some embodiments the plurality of seeds is a mixture of whole seeds and partial seeds. The plurality of seeds can have kernels, shells and/or partial kernels and shells. A variety of types of seeds can be included in the animal feed particles such as sunflower seeds, cereals, pseudocereals, grains, legumes, grasses, and the like.


The animal feed particles 132 of the feed mixture 130 can also have additional constituents that are consistent with the diet of the particular animal to be fed. In some embodiments the animal feed particles 132 has a plurality of dehydrated invertebrates and/or a plurality of dehydrated insects. The plurality of dehydrated invertebrates can be mealworms, black soldier fly larvae, and/or other types of worms or larvae in various embodiments. The plurality of dehydrated insects can be grasshoppers, crickets, beetles, and/or flies, as examples. Further, in some embodiments the animal feed particles 132 can have dehydrated vegetables, dehydrated fruit, and/or dehydrated herbs. In some embodiments, the animal feed particles can include grit, such as shell grit.


The term “dehydrated” is used herein to refer to moisture having been removed from the referenced product, and should not be interpreted as limiting the particular method used to remove the moisture. Generally the moisture content of each of the types of particles in the animal feed particles 132 will be sufficiently low to be rendered shelf stable for at least a year. The type of particle will generally dictate the maximum acceptable moisture content. For example, each type of dehydrated invertebrate, insect, seed, and other plant matter used as animal feed particles 132 can have a moisture content of less than 12%, 10%, 8%, 6%, 4%, or even 3%, which can be similar to or different than the moisture content of other types of animal feed particles 132 in the feed mixture 130.


The seed butter 134 coating each of the plurality of animal feed particles 132 generally is in the form of a puree or paste such that the seed butter 134 can provide a slight binding force on the animal feed particles 132. The seed butter 134 is generally no more than 20% of the feed mixture 130 by weight. In some embodiments the seed butter 134 is no more than 15% or even 10% of the feed mixture 130 by weight. In various embodiments the seed butter 134 is at least 3% or at least 5% of the feed mixture 130 by weight. The seed butter 134 generally has a moisture content of less than 6%, 4% or even 2%. In some embodiments the seed butter 134 has a moisture content of less than 1%.


The seed butter 134 is formed from ground, crushed, pressed, macerated, or puréed seed. A variety of types of seeds can be used to make the seed butter such as sunflower seeds, peanuts, soybeans, flax, pulses, tree nuts, and the like. In some embodiments the seed butter is SunButter®, which is manufactured by SunButter LLC based in Fargo, N. Dak. In some other embodiments the seed butter is peanut butter or almond butter. In a number of embodiments the seed butter is a mixture of multiple types of seed butters.


The seed butter 134 is generally at least 30% fat content by weight and generally no more than 55% fat content by weight. In some embodiments, the fat content of the seeds used to create the seed butter is about equal to the fat content of the seed butter. In other embodiments, particularly if the fat content of the seeds used to make the seed butter is less than 30% by weight, supplemental fat can be added during manufacturing of the seed butter to achieve the 30%-55% fat content by weight. The supplemental fat can be seed oil, suet, or shortening, as examples. In such embodiments it can be desirable to homogenize the seeds and the supplemental fat to achieve a substantially homogenous seed butter 134. Furthermore, if the fat content of the seed butter 134 is above 55% by weight, the seed butter 134 would need to be homogenized to prevent the oils from separating.


In a variety of embodiments the seeds used to manufacture the seed butter 134 can be roasted before forming the seed butter 134. Roasting the seeds can enhance, as examples, the smell, flavor, and color of the seed butter 134 and, therefore, the resultant animal feed mixture 130 incorporating such seed butter 134. As an example, the relatively pleasant smell of a seed butter 134 formed from roasting the constituent seeds can counteract relatively unpleasant smells associated with animal feed particles such as dehydrated invertebrates and/or insects. Roasting can also reduce the amount of moisture in the seed butter 134.


As mentioned above, the container 110 generally defines a cavity 120 that contains the feed mixture 130. The container 110 can have a variety of different configurations and can be constructed of a variety of different materials and combinations of materials. In some embodiments, the container 110 is constructed of paper or cardboard. The paper can be recycled, recyclable, and/or compostable paper or cardboard. In some embodiments, the container 110 is constructed of a plastic such as a recycled, recyclable or/or compostable plastic. In some embodiments the container 110 is constructed of peat or other vegetable matter. While the container 110 is depicted as having a bowl shape in the current figures, the container can be molded or otherwise formed to have alternate shapes, including ornamental shapes. The container 110 defines a rim region 114 around an opening 112 in communication with the cavity 120. The removable cover 140 is coupled to the rim region 114 to isolate the opening 112 and the cavity 120 from the environment outside the container 110.


The removable cover 140 can be constructed of a variety of different materials and combinations of materials. In some embodiments, the removable cover 140 is a heat-shrink film. In some embodiments, the removable cover 140 is a sheet of paper or cardboard. The removable cover 140 can be coupled to the container 110 with an adhesive, such as an adhesive film/web or an adhesive paste. The adhesive can be a pressure-sensitive adhesive, heat activated adhesive, chemically-activated adhesive, and the like. In some embodiments, including the one depicted, the removable cover 140 can define a tab 142 that extends outward from the rim region 114. The tab 142 can be configured to be grasped by a user for removing the removable cover 140.


There are a variety of different manufacturing methods and processing steps that are consistent with embodiments of the technology disclosed herein. FIG. 3 is one example flow chart. In this example embodiment the seed butter is heated 310 and animal feed particles are coated with seed butter 320. The feed mixture is deposited in a container cavity 330 and the feed mixture is compressed in the container cavity 340.


The seed butter can be consistent with seed butters described above in the discussions of FIGS. 1 and 2. The seed butter is generally heated 310 to reduce the viscosity of the seed butter to properly coat the animal feed particles 320. The particular temperature that the seed butter is heated to can depend on the type of seeds in the seed butter, the type of fats in the seed butter, and the particular manufacturing equipment used for coating the animal feed particles 320. The seed butter is generally heated 310 above ambient temperature until it forms a liquid and then the animal feed particles are coated with the seed butter 320.


The animal feed particles can be consistent with animal feed particles discussed above with reference to FIGS. 1 and 2. The animal feed particles can be coated with the seed butter 320 through a variety of different approaches and combinations of approaches. In embodiments, the heated seed butter is drizzled on the animal feed particles and mixed thoroughly with a mixer. The heated seed butter and the animal feed particles can be layered and then mixed. In some embodiments, some constituents of the animal feed particles, such as dehydrated invertebrates and/or insects, can be added after mixing some other of the constituents of the animal feed particles and heated seed butter. Such a step can be desirable to limit fragmenting and/or disintegration of the later-added constituents under the forces of the mixer.


Another example approach to coating the animal feed particles with the seed butter 320 is depicted in FIG. 4. In this example, the animal feed particles are translated through a spraying region 322, the seed butter is sprayed on the animal feed particles 324 in the spraying region to form a feed mixture, and the feed mixture is mixed 326.


In various embodiments the animal feed particles are translated through the spraying region 322 and the seed butter is sprayed on such particles 324 in the spraying region generally simultaneously. The spraying region is generally an area in space that receives the spraying heated seed butter and that the animal feed particles translate through. In some embodiments the animal feed particles are dropped such that the force of gravity translates the animal feed particles through the spraying region 322. In another example embodiment, the animal feed particles translate through a spraying region on a conveyor belt. Other approaches can also be used to translate the animal feed particles through the spraying region 322.


The heated seed butter can be sprayed on the animal feed particles 324 in the spraying region using a variety of different types of equipment and combinations of equipment. In one embodiment the heated seed butter is sprayed through a spray nozzle, a spin spray coater, and/or using an ultrasonic spray coater. In one example, a Mistcoater Liquid Applicator manufactured by Automated Process Equipment Corporation based in Lake Odessa, Mich. is used to spray the heated seed butter on the animal feed particles 324. In some embodiments the spray coater is also configured to heat the seed butter 310 (FIG. 3) prior to spraying the seed butter on the animal feed particles 324 (FIG. 4). In such embodiments, the seed butter will have been heated 310 to achieve a viscosity sufficient to pass through spraying equipment to be sprayed onto the animal feed particles 324.


Generally the heated seed butter is sprayed such that each of the animal feed particles are coated with seed butter. The animal feed particles can be coated with seed butter at least on one side of each of the particles. The seed butter-coated animal feed particles can be referred to as a feed mixture. The amount of seed butter sprayed on the animal feed particles is generally consistent with the amounts described above in the discussion of FIGS. 1 and 2.


In some, but not all embodiments, the feed mixture is mixed 326 after the animal feed particles have been sprayed with seed butter 324. Mixing the feed mixture 326 can further distribute the seed butter coating over the surfaces of the animal feed particles. Mixing the feed mixture 326 can create a homogenous seed butter coating over a substantial portion of the animal feed particles. In one example the feed mixture is passed through a mixer that mixes the feed mixture 326. The mixer can be a ribbon mixer, a paddle mixer, a tumbler, or other types of mixers. In some embodiments mixing the feed mixture 326 can be omitted, however. In other embodiments, the mixing 326 is executed before depositing the feed mixture in the container cavity 330 (FIG. 3).


Returning again to FIG. 3, the feed mixture is generally deposited into a container defining a cavity 330. The container can be consistent with containers discussed above with reference to FIGS. 1 and 2. The feed mixture can be deposited into a container cavity with depositor equipment, in various embodiments. Once the feed mixture is deposited in the container cavity 330, the feed mixture can be compressed in the cavity 340. The feed mixture is compressed in the cavity 340 with sufficient pressure to cause the feed mixture to substantially conform to the shape of the cavity. Further, the feed mixture is compressed in the cavity 340 with sufficient pressure to bind coated animal feed particles to abutting animal feed particles in the cavity. Generally the pressure applied to the feed mixture in the cavity is no more than 10 psi. In various embodiments the pressure applied to the feed mixture in the cavity is no more than 7 psi. In some embodiments the pressure applied is less than or equal to 3 psi, 4 psi, or even 5 psi. In some embodiments the pressure applied is greater than or equal to 0.25 psi, 0.5 psi, or even 1 psi.


In some embodiments, a removable cover is adhered to the container 350. Adhering the removable cover to the container 350 encases the feed mixture between the container and the removable cover. The removable cover can be adhered to a rim region defined by the container, which is described above with reference to FIGS. 1 and 2. The removable cover can be constructed of materials described above with reference to FIGS. 1 and 2.


The technology disclosed herein can have a variety of advantages. For example, in manufacturing, there is generally a relatively short period of time between depositing the feed mixture in the container cavity 330, compressing the feed mixture in the container cavity 340 and adhering the removable cover to the container 350. Generally the removable cover can be adhered to the container 350 as soon as the seed butter sufficiently cools. In some embodiments the seed butter is sufficiently cooled when it reaches a temperature of 75° F. or less, or 70° F. or less. Little to no drying time is required to allow moisture to evaporate from the feed mixture because moisture is not added to the feed mixture during the manufacturing process.


It should also be noted that, as used in this specification and the appended claims, the phrase “configured” describes a system, apparatus, or other structure that is constructed or configured to perform a particular task or adopt a particular configuration. The phrase “configured” can be used interchangeably with other similar phrases such as “arranged”, “arranged and configured”, “constructed and arranged”, “constructed”, “manufactured and arranged”, and the like.


All publications and patent applications in this specification are indicative of the level of ordinary skill in the art to which the present technology pertains. All publications and patent applications are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated by reference.


This application is intended to cover adaptations or variations of the present subject matter. It is to be understood that the above description is intended to be illustrative, and not restrictive.
