Abstract
A method of manufacturing coated feed pellets comprises wetting the feed pellets with a mist of unheated water and then enclosing the wet feed pellets in a coating material. The feed pellets are initially separated by a rotating disk and then passed through a mist of unheated water generated by dripping water onto a concave disk rotating in the opposite direction of the first rotating disk. The wet feed pellets are then enclosed in a mixture comprising of a mixture of milk sugars, icing sugars and flavors. This coating material not only increases the palatability of the feed pellet, it also crystalizes upon drying, thereby forming a protective casing around the feed pellet. This prevents breakdown of the feed pellet during shipping and handling. As a consequence, feed pellets with a fat content that is higher than currently possible can be manufactured.
Description
C ~ 4 1 39 IMPROVED METHOD FOR MANUFACTURING COATED FEED PELLETS
The present invention relates to an apparatus and a process for the manufacture of coated feed pellets.
5 BACKGROUND OF THE INVENTION:
The pelleting of feed for livestock is a well known process that enhances palatability and thereby increases the growth rate for livestock. The problem with pelleting feed for some livestock, such as baby pigs, is that the addition of high fat levels to the ration causes the feed pellet to become soft.10 Consequently, transportation and handling of the feed pellet will lead to thebreakdown of the feed pellet. This in turn results in too many fine particles, which has the consequence of reducing palatability and thus feed intake.
These soft feed pellets are also heat labile, as moist heat can lead to not onlybreakdown of the feed pellets but may also denature the nutritional 15 components of the feed pellets.
US Patent No. 5,132,142 discloses an apparatus for producing coated pellets by layering powder onto particles. The apparatus comprises a vessel and a rotor supported for rotation around a vertical axis and having a supporting surface for supporting particles. The apparatus comprises 20 furthermore a feeding means for introducing a powder and a liquid into a processing space inside said vessel and adjacent to the supporting surface of said rotor. The feeding means comprises an introducing member which consists of a liquid outlet and a powder outlet, wherein one of the outlets encompasses the other. The process comprises introducing particles into the 25 vessel and subjecting them to an atomized spray of liquid and powder. At room temperature, the ratio of powder to liquid is approximately 1:1 or 1.5:1.
This ratio can be increased at higher temperature which in turn decreases the time required for the coating process and drying of the pellets.
CA21 84~. 39 While US Patent No. 5,132,142 represents an advance over the prior art in that there is little loss of coatin~ material and the pellets produced are of uniform size and shape, the described process is not ideally suited for the manufacture of coated feed pellets containin~ hi~h fat content. Specifically, 5 use of the apparatus described therein would subject the feed pellets to rotational forces during the coating process which would cause breakdown.
Furthermore, the coatin~ process described therein is most efficient at hi~her temperature, which, as stated above, would result in breakdown of the feed pellet. While the coatin~ process can be carried out at room temperature, 10 doin~ so si~nificantly increases dryin~ time, durin~ which time the apparatus cannot be used.
SUMMARY OF THE INVENTION:
It is one object of the present invention, therefore, to provide an 15 improved process for manufacturin~ coated feed pellets.
Accordin~ to one aspect of the invention, there is provided a method for manufacturin~ coated feed pellets, comprisin~:
wettin~ the feed pellets via a spray consisting of liquid droplets; and directin~ the wet feed pellets into a bed of powder material, such that 20 the wet feed pellets become enclosed within the powder material, producing coated feed pellets.

DETAILED DESCRIPTION:
In Figure 1 is shown an overview of the apparatus for manufacturing coated feed pellets.
The invention comprises a mist generating system, a pellet separator, a 15 mist chamber, a coating system, a coated feed pellet separator and a powder recycling system.
In Figure 2, the mist generating system and the pellet separator are shown in cross-section. The mist generating system comprises a water pipe 1, having a vertical and a horizontal component. The horizontal component is 20 attached to an outside water source. Water pressure can be controlled at a first valve 2 or, alternately, the water can be shut off completely at a second valve 3. Both valves are located on the horizontal component of the water pipe 1. The vertical component of the water pipe 1 enters the mist chamber through a 1.5" hollow shaft 4. At the end of the vertical component of the 25 water pipe 1 is a nozzle 5 situated approximately 12 cm above a concave rotating disk 6 revolving at 1800 RPM which is located within the mist chamber. The concave rotating disk 6 is driven by a 1" shaft 7 located below ~ A ~ 4 ~ ~ 9 the plane of the concave rotating disk 6. The 1" shaft is connected via a belt and pulley system 8 to a 1 horsepower motor 9.
The pellet separator comprises a variable speed conveyor that terminates at a duct 10. The duct 10 is connected to a walled vessel 11 S which also contains the mist chamber. The entry point of this duct 10 into the walled vessel 11 is situated above a hollow tube of fixed height 12 located within the mist chamber. Surrounding the hollow tube of fixed height 12 is a hollow tube of variable height 13. Directly below the hollow tube of fixed height 12 and the hollow tube of variable height 13 is a flat rotating 10 disk 14, wherein the flat rotating disk 14 has a diameter equal to or greaterthan the diameter of the hollow tube of variable height 13. Furthermore, the flat rotating disk 14, revolving at 800 RPM, is driven by a 1.5" hollow shaft 4 located above the plane of the flat rotating disk 14. The 1.5" hollow shaft 4 is connected to a 1 horsepower motor 15 via a belt and pulley system 16.
The mist chamber comprises a nozzle 5 located at the lower base of the 1.5" hollow shaft 4 as described above as part of the mist generating system. Approximately 12 cm below the nozzle is the concave rotating disk 6 described above as a component of the mist generating system. The mist chamber is located within the walled vessel 11 described above as also 20 containing the pellet separator. Connected to the base of the walled vessel 1 1 is a sloped and tapered shaft 17 that is connected to the main chamber 18 of the coating system via a duct 19.
In Figure 3, the coating system, the coated feed pellet separator and the powder recycling system are shown in cross-section. The coating system 25 comprises a main chamber which is equipped with a sensing system for determining if the powder level is too high 20 or too low 21. Connected to the base of the main chamber 18, below the level of entry of the duct 19 from the walled vessel 11 is a baffled vibrating tank 22. The opening at the ~A21 ~4t 39 base of the baffled vibrating tank 22 is regulated by a sliding gate 23. This opening is situated directly above a declined agitating conveyor with a perforated floor 24 that is part of the coated feed pellet separator.
The coated feed pellet separator comprises a declined agitated 5 conveyor with a perforated floor 24. Both the declined conveyor with a perforated floor and the baffled vibrating tank 22 are agitated back and forth by a rocking platform 25 connected to a 2 horsepower motor 26 by a belt and pulley system 27. At the terminus of the declined agitating conveyor with a perforated floor 24 is a duct 33 for discharge of the coated feed pellets. A
10 feed pellet 34 encased in coating material 35 is shown in cross-section in Figure 4 and in side view in Figure 5.
The powder recycling system consists in part of an inclined screw conveyor belt 28 located directly below the declined agitating conveyor with the perforated floor 24. At the elevated terminus of the screw conveyor 28 is 15 a duct 29 into a narrow chamber 30, wherein the material is elevated via a vertical screw conveyer 31. At the apex of the vertical screw conveyor 31 is a duct 32 to the main chamber 18 of the coating system.
In operation, water dripped from the water pipe 1 onto the concave rotating disk 6 generates a spray of water droplets in the mist chamber. Feed 20 pellets enter the pellet separator from the variable speed conveyor via a duct 10. Said duct 10 directs the feed pellets into the hollow tube of fixed height 12 situated above the flat rotating disk 14. The hollow tube of variable height 13 serves as a collar so as to restrict access of the feed pellets to the flat rotating disk 14. Raising the height of the hollow tube of variable height 13 25 will increase the flow rate of the feed pellets into the mist chamber. Upon encountering the flat rotating disk 14, the feed pellets are separated into individual units by centrifugal force and dropped down into the mist chamber.
Therein, the feed pellets pass through the spray of water droplets and are directed into the main chamber 18 of the coating system, which contains a quantity of the coating material that is in at least four fold excess of the amount required to coat the feed pellets. The mixture of powder material and feed pellets passes into the baffled vibrating tank 22. The combination of 5 agitation and the baffles promotes coatin~ of the feed pellets. The mixture ofcoatin~q material and coated feed pellets exits the baffled vibrating tank via an opening with a sliding gate 23. Openin~q the sliding gate 23 will increase the rate of flow of the mixture out of the baffled vibrating tank 22. Next, the mixture of feed pellets and coating material is deposited onto the declined 10 agitating conveyor with a perforated floor 24. Shaking of this conveyor system separates the coated feed pellets from the unused powder. At the terminus of the declined ayitating conveyor with the perforated floor is a duct for discharge of the coated feed pellets 33. The unused powder passes through the perforated floor to an inclined screw conveyor 28. The inclined 15 screw conveyor carries the unused powder material to a vertical screw conveyor 31 via a duct 29. At the apex of the vertical screw conveyor 31 is another duct 32 which returns the unused powder material to the main chamber 18 of the coating system.
Since various modifications can be made in my invention as herein 20 above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
