The present disclosure relates to the field of gravity-fed granulated matter treatment apparatuses, and in particular to a treatment apparatus including baffles that are shaped and arranged to generate a spiral flow in the granulated matter, like seeds, whereby dispersion of treatment additives in the granulated matter is enhanced.
Certain granulated agricultural products, such as seeds, grains, and fertilizers, are often treated with additives to protect them or produce desired qualities therein. For example, seed can be treated with biological agents and/or pesticides that protect the seeds from pests and disease. Indeed, protracted storage of grains and seeds can provide an ideal environment for growth of molds, some of which are toxic to people and animals, such as grain-fed swine, calves, rabbits, pheasants, chickens, turkeys and ducks. Likewise, it is common for fertilizer to be impregnated with additives to enhance desired qualities or produce desired results, such as enhanced flowability, shelf stability, or bioavailability.
However, treatment methods and additives can vary greatly. For example, additives can often be dry products designed to be mixed with granulated agricultural products or fluid solutions designed to coat granulated agricultural products. While there are a great number of apparatuses on the market to provide treatment of these products, they are often bulky, complex, invariable, and/or energy intensive. In fact, these characteristics are often necessary side effects of to ensure sufficient treatment. For example, certain “portable” treatment devices are often so large that they require a trailer for transport and require power to operate a mechanical mixing device. In contrast, another treatment method involves passing granulated agricultural products through a vertical treatment chamber into which both a flow of additive and granulated matters is passed and having baffles to deflect the matter and additive as it is pulled by gravity from top to bottom so that the additive and granulated matter mix. Although these vertical treatment chamber devices are desirable due to their reliance on gravity, lacking a mechanical mixing device and not requiring power to operate such, they often are bulky. Moreover, each of these vertical treatment chamber devices often focus only on a single type of granulated matter and additive.
Therefore, an unmet need remains for a treatment apparatus which incorporates design features allowing the apparatus to be smaller and more mobile, user-friendly, and more versatile in use while remaining efficient and effective in their treatment of a variety of granulated agricultural products with liquid or dry additives.
This summary is provided to introduce in a simplified form concepts that are further described in the following detailed descriptions. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it to be construed as limiting the scope of the claimed subject matter.
In view of the above, the present disclosure provides, in aspects, a gravity-fed treatment apparatus for granulated agricultural matter that is smaller, more mobile, user-friendly, and more versatile in use while remaining efficient in treatment due to its incorporation of various design features.
According to one or more embodiments, a gravity-fed treatment apparatus for the dispersion of an additive into a flow of granulated matter comprises a vertical treatment chamber having an inlet, at a top, and an outlet at a bottom, two U-shaped channel members having arms abutting one another so they define the periphery of an interior of the chamber between the top and bottom, a plurality of vortex baffles extending from the periphery into the interior of the chamber where each vortex baffle has a flat portion and a flaring portion curving up and away from a plane encompassing the first surface, and a first feed port disposed through one of the U-shaped channel members to deposit additive into the flow of granulated matter. In embodiments, some of the granulated matter flow from the inlet spirals around an axis passing through the top and bottom of the chamber as it is pulled by gravity towards the outlet due to the deflection of the baffles enhancing dispersion of the additive through the flow of granulated matter.
According to embodiments, the gravity-fed treatment apparatus further has a frustoconical-shaped hopper affixed to the inlet, through which granulated matter is passed.
In embodiments, the vortex baffles are serially disposed from opposed portions of the periphery, to enhance the spiral flow and, thereby, the dispersion of additive relative to the granulated matter.
In further embodiments, each of the vortex baffles are affixed to portions of the periphery so that the angle they are disposed at relative to the periphery is fixed. In other embodiments, one or more of the vortex baffles are pivotally affixed to the periphery so that the respective angle of the vortex baffle relative to the periphery is alterable. In certain embodiments, the pivotally affixed vortex baffle is operably connected to an adjustment bar configure to allow for infinite adjustment of the respective angle of the pivotally affixed vortex baffle. In embodiments, the adjustment bar is disposed on an opposed side of the periphery from the interior of the chamber. In other embodiments, the pivotally affixed vortex baffle contacts a protrusion from the periphery to secure the vortex baffle at a set respective angle. In additional embodiments, the location of the protrusion is adjustable relative to the periphery and the location is related to the set respective angle.
In more embodiments, one or more of the vortex baffles are removably affixed to the periphery. In certain embodiments, a portion of the removably affixed vortex baffle is disposed into and in frictional engagement with a slot into a portion of one of the U-shaped channel members.
In embodiments, the first feed port is in communication with a first metering device to control the input rate of additive to the interior of the chamber. In certain embodiments, the additive comprises a fluid, the first metering device comprises a chemical metering pump in fluid communication with the first feed port, and the first feed port comprises a nozzle configured to spray the additive into the interior of the chamber where it contacts the flow of granulated matter. In various embodiments, the additive is non-fluid and the first metering device is one of a fluted feed type, internal double run type, cup feed type, cell feed type, brush feed type, auger feed type, picker wheel type, and star wheel type. In further embodiments, the chamber further comprises a second feed port disposed through one of the U-shaped channel members and a second metering device in communication with the second feed port, wherein the second metering device is configured to control the input rate of additive to the interior of the chamber. In certain embodiments, the first metering device and second metering device are operably linked through a calibration unit configured to control the input rate of additive to the interior through each of the first feed port and second feed port.
In additional embodiments, the flow through the inlet is through a first metering device configured to control the flow rate of granulated matter into the interior of the chamber. In certain embodiments, the apparatus further comprises a second metering device in communication with the first feed port, wherein the first metering device and second metering device are operably linked through a calibration unit configured to maintain a preset ratio of the additive to granulated material in the flow.
According to one or more embodiments, a gravity-fed treatment apparatus for the dispersion of an additive into a flow of granulated matter comprises a vertical treatment chamber having an inlet, at a top, and an outlet at a bottom, at least one wall defining the periphery of an interior of the chamber between the top and bottom, a plurality of vortex baffles extending from the periphery into the interior of the chamber where each vortex baffle has a flat portion and a flaring portion curving up and away from a plane encompassing the first surface, and a first feed port disposed through one of the U-shaped channel members to deposit additive into the flow of granulated matter. In embodiments, some of the granulated matter flow from the inlet spirals around an axis passing through the top and bottom of the chamber as it is pulled by gravity towards the outlet due to the deflection of the baffles enhancing dispersion of the additive through the flow of granulated matter.
In some aspects of the present disclosure, a method is provided for treating granulated matter with an additive, the method including transporting the granulated matter to an inlet of a chamber, introducing the granulated matter from the inlet into the chamber, establishing a spiral flow of granulated matter in the chamber by providing a plurality of vortex baffles extending angularly away from portions of at least one wall of the chamber for deflecting and influencing the granulated matter flowing through the chamber, introducing the additive into an upper portion of the chamber, contacting the granulated matter with additive during the spiral flow as granulated matter moves towards an outlet of the chamber so the granulated matter becomes treated, and receiving treated granulated matter from an outlet of the chamber. In one instance, each of the plurality of vortex baffles in the method have a flat plate portion with a first surface and a flaring portion curving up and away from a plane encompassing the first surface.
In certain instances, the additive of the method is a dry compound and introducing the additive into the upper portion of the chamber involves introducing the additive from the inlet into the chamber. In another instance, the additive of the method is a dry compound and introducing the additive into the upper portion of the chamber involves introducing the additive from a port in an upper portion of the chamber.
In other instances, the additive of the method is a fluid solution and introducing the additive into the upper portion of the chamber involves introducing the additive from a nozzle disposed in an upper portion of the chamber. In at least one instance, the additive is introduced at a rate that is controlled by a chemical metering pump.
In certain aspects, the vortex baffles are removably attached to portions of the one or more walls of the chamber.
In further aspects, the method includes the step of adjusting the angle at which some or all of the vortex baffles extend away from the one or more walls of the chamber to accommodate optimum angles for certain granulated matter. In particular aspects, the rate that at least one of the granulated matter and additive is introduced in the method is controlled by a metering device.
In at least one aspect, the rate that both the granulated matter and additive is introduced is calibrated through operative control of the metering device.

In general, the apparatus 10 comprises a vertical chamber 20, as in
The ability of the apparatus 10 to provide enhanced mixing, as compared with treatment devices having flat baffles, allows for a more energy efficient device (due to the use of gravity as part of the treatment process), which can be smaller, particularly in vertical height, and have fewer baffles. For example, an gravity fed apparatus design not producing a spiral flow based on the design and layout of flat baffles therein commonly needs to be up to 10.5 feet tall to provide sufficient treatment of granulated matter. However, an apparatus 10 according to the present embodiments having vortex baffles 46 disposed in the chamber 20 produces a spiral flow and only needs to be approximately 4 feet tall to produce a similar level of treatment. Indeed, in
While various features and elements have been described in reference to particular embodiments and variations above, it is to be understood that no limitation of the scope of this disclosure is hereby intended. Thereby, elements and features might be utilized in any combination and for any embodiment to which it is particularly useful. To further promote understanding of the principles of the present disclosure, additional discussion related to particular elements of the present discussion is provided below.
In embodiments, the vertical chamber 20 comprises one or more walls 30 which form the periphery for the interior 44 of the chamber 20. In embodiments, the number of walls 30 may facilitate a particular shape for chamber 20. For example, a cylindrical shape chamber 20 having a single circular wall 30, a triangular prism shaped chamber 20 having three walls 30, and a rectangular prism shaped chamber 20 having four walls, as in
In at least one embodiment, the vertical chamber 20 comprises two U-shaped channel members 32 having edges 42 that abut together to facilitate the formation of the walls 30 of the chamber 20 and define the interior 44 thereof as in
U-shaped channel members 32 provide several benefits including easy access to the interior 44 facing portions of the chamber 20, such as vortex baffles 46, and the convenient grouping of elements of the apparatus 10 to allow for simple assembly and maintenance. Such benefits are particularly apparent in embodiments where the U-shaped channel members 32 have portions removably affixed together as in
In another embodiment, a plurality of chambers 20 can be affixed together as in
In embodiments, the inlet 22 at the top 24 and outlet 26 at the bottom 28 might be the size of the entire respective top 24 or bottom 28, making the chamber 20 open on either respective end. In other embodiments, the inlet 22 and outlet 26 may be a smaller size, such as that of a portion of the top 24 or bottom 28, making the chamber 20 relatively more closed. The embodiments of
In embodiments, the apparatus 10 includes vortex baffles 36 affixed to the chamber 20 about the periphery of and extending angularly into the interior 44. In embodiments, each of the vortex baffles 46 has a shape that is different from a flat baffle. Indeed, in embodiments, each vortex baffle 46 includes a flat portion 48 and flaring portion 52. The flaring portion 52, in such embodiments, curves up and away from a plane passing through a surface 50 of the flat portion 48 as shown in
In embodiments, each vortex baffle 46 may be shaped and arranged within the chamber 20 to provide for a particular direction of the spiral flow. For example, the shape of each of the vortex baffles 46 in
While significant description has been provided herein regarding certain embodiments of the vortex baffle 46, it is also foreseen that other shapes might further be utilized. Indeed, the previously disclosed vortex baffle 46 may be only one shape capable of producing the desired spiral flow, rotation, and mixing under the influence of gravity. For example, one embodiment of a vortex baffle 46 could have a portion demonstrating a sinuous curve and a particular slope which, during deflection of granulated matter 12 and additive 14 generates similar desired motion and enhanced mixing. Accordingly, the term vortex baffle 46 utilized herein encompasses a baffle that is not flat and that due to its shape and its disposition within the chamber, produces the above-mentioned desired motion and enhanced mixing.
In embodiments, the vortex baffles 46 are affixed to the interior surface of the walls 30 or U-shaped channel members 32 making up the chamber 20 and extend angularly therefrom. In embodiments, the angle at which the vortex baffle extends 46 into the interior 44 is a factor which directly influences the mixing efficiency by affecting the spiral flow and motion of the granules in a flow of granulated matter 12 with the additive 14. The angle is not alterable in certain embodiments, such as in
Indeed, in one embodiment the angle is alterable through the removal and replacement of removably attached vortex baffles with others which facilitate a different angle, such as in
In other embodiments, the angle is adjustable and user selectable through other means, such as that shown in
As shown in
In embodiments, the vortex baffles 46 are affixed to the interior surface of opposed walls 30 or U-shaped channel members 32 making up the chamber 20. In embodiments, the vortex baffles 46 are arranged serially along opposed walls 30, or portions of walls 30 or U-shaped channel members 32 as in
In embodiments, the apparatus 10 has one or more feed ports 58, as shown in
In embodiments, the apparatus 10 includes a metering device 84 for a liquid additive 14, as shown in
In further embodiments, the metering device 84, 88 may be selectively adjustable to control the rate of material being moved through the inlet 22 or feed port 58. Here, the rate is understood as the amount of material moved through the metering device 84, 88 per unit of time or per operative motion of the metering device 84, 88. For example, in an embodiment, a fluted feed roller metering device 84 may be adjustable to change the amount of material moved therethrough. Moreover, it is also foreseen that the metering device 84, 88 may have additional adjustable internal portions which limit the flow of material to control the standard rate of material therethrough.
In certain embodiments, multiple metering devices 84, 88 can be controlled through a calibration unit 90 in operative communication with each as in
In embodiments, the apparatus 10 can include a hopper 80 affixed to the top 24 of a chamber 20 so that granulated matter 12 passing into the inlet 22 must first pass through the hopper 80, as in
In embodiments, a hopper 80 may be constructed of materials such as metal, plastic, rubber, or other useful material. Indeed, in an embodiment, a hopper 80 might even be constructed of or with wood. In certain embodiments, the hopper 80 may have a selectively engageable cap or lid for one or more of its apertures to enclose or protect the chamber 20 when not in use. For example, a lid on an opening of the hopper 80 can prevent water or other material from entering the hopper 80 and/or to secure and make the apparatus 10 safer when not in use. In embodiments, an opening of the hopper 80 might be blocked by a cover, such as a flexible tarp or rigid panel.
In certain embodiments, the hopper 80 may have one or more sensors to determine conditions within the hopper 80, such as the level of material in the hopper 80 or the humidity level inside the hopper 80. In at least one embodiment, the hopper 80 has a level sensor to indicate the presence of granulated matter 12 up to a certain level in the hopper 80. The level sensor may be of a contact or non-contact variety. Information from one or more sensors can be utilized by a calibration unit in various embodiments to control a metering device 88, such as that for the granulated matter. In certain embodiments, the hopper 80 may include a light which is selectively operated based on information received from a sensor. For example, the hopper 80 may include a light which turns on when the hopper 80 is full, to provide an indication to a user of the device.
In embodiments, the apparatus 10 includes a conveyor 100, as in
In various embodiments, the present invention provides an apparatus for treating certain granulated matter 12, including agricultural products like seeds, with liquid or dry additives 14. Indeed, seed that can be treated with the apparatus 10 include that from soybean, peanut, corn, legume, cereal, grass, cotton, oil, or vegetable plants. Moreover, seed can include that from a combination of sources. Also, it is foreseen that other granulated matter 12 agricultural products might be coated or mixed with an additive 14 through the use of the apparatus 10 herein. For example, certain fertilizers, like pearled urea, might be treated with an additive 14 through the apparatus 10. Treatment herein is understood to mean the agricultural product is coated, impregnated, and/or mixed with the additive 14.
Further, the additives 14 can include any desired and suitable compound. For example, granulated matter 12 might be treated with a pesticide to protect such products or soil it is applied to from pests. Moreover, granulated matter 12 might be treated with microbial compounds to enhance plant growth and resilience or prevent mold. Further, granulated matter 12 might be treated with a cellulose fiber compound to enhance flowability. However, the above examples are not to be considered limiting in any way as a variety of compounds might be considered suitable additives 14 and such compounds are readily known and apparent to those of skill in the art.
