Poultry chiller with multi-blade long-pitch auger
An auger-type poultry chiller having an auger with multiple long-pitch auger blades. The blades of the auger create pockets that spiral around the auger shaft and extend the length of the auger. While the product in the chiller is locked into a certain pocket, it is not locked into a certain spot lengthwise in the chiller. The product, therefore, is able to distribute evenly along the length of the chiller within its pocket even if there are gaps in loading time or if unloading stops momentarily.
1. A poultry chiller, comprising:
a tank for receiving poultry carcasses and holding chilled water, wherein said tank comprises an inner wall surface and an outer wall surface, wherein said tank comprises an inlet end and an outlet end; and
an auger mounted in said tank, wherein said auger is comprised of a shaft and a first auger blade, a second auger blade, and a third auger blade attached to said shaft,
wherein said first auger blade, said second auger blade, and said inner wall surface of said tank forms a first spiral pocket that extends from said inlet end of said tank, wherein said second auger blade, said third auger blade, and said inner wall surface of said tank forms a second spiral pocket that extends from said inlet end of said tank, wherein said third auger blade, said first auger blade, and said inner wall surface of said tank forms a third spiral pocket that extends from said inlet end of said tank.
2. The poultry chiller of claim 1 , wherein said first auger blade has a long pitch, wherein said long pitch of said first auger blade urges poultry carcasses forward from said inlet end of said tank when said auger rotates and causes poultry carcasses to rotate around said shaft when said auger rotates.
3. The poultry chiller of claim 2 , wherein said long pitch of said first auger blade is in the range of 15-40 feet.
4. The poultry chiller of claim 1 , wherein said tank comprises an auger section and an unloader section.
5. The poultry chiller of claim 4 , wherein said auger section of said tank comprises said auger.
6. The poultry chiller of claim 4 , wherein said unloader section of said tank comprises a plurality of unload paddles.
7. The poultry chiller of claim 4 , wherein said unloader section of said tank comprises an unload chute.
8. The poultry chiller of claim 4 , further comprising a baffle plate, wherein said baffle plate separates said auger section and said unloader section of said tank.
9. The poultry chiller of claim 4 , wherein said unloader section of said tank is raised from said auger section of said tank.
10. The poultry chiller of claim 1 , wherein said tank comprises a volume of chilled water, wherein said tank is filled with said volume of chilled water to a top of said tank.
11. A poultry chiller, comprising:
a tank for receiving poultry carcasses and holding chilled water, wherein said tank comprises an inner wall surface and an outer wall surface, wherein said tank comprises an inlet end and an outlet end; and
an auger mounted in said tank, wherein said auger comprises a plurality of long pitch auger blades, wherein said auger urges poultry carcasses forward from said inlet end of said tank when said auger rotates and causes poultry carcasses to rotate around said shaft when said auger rotates;
wherein said plurality of long pitch auger blades forms a plurality of spiral pockets between said plurality of auger blades and said inner wall surface of said tank.
12. The poultry chiller of claim 11 , wherein said plurality of long pitch auger blades have a pitch in the range of 15-40 feet.
13. The poultry chiller of claim 11 , wherein said plurality of auger blades comprises three auger blades.
14. The poultry chiller of claim 11 , wherein said tank comprises an unloader section.
15. The poultry chiller of claim 14 , wherein said unloader section of said tank comprises a plurality of unload paddles and an unload chute.
16. The poultry chiller of claim 11 , wherein said tank comprises a volume of chilled water, wherein said tank is filled with said volume of chilled water to a top of said tank.
17. A poultry chiller, comprising:
a tank; and
an auger mounted in said tank, wherein said auger comprises a shaft and a first blade, a second blade, and a third blade, wherein said shaft has a first end and a second end, wherein said first blade spirals around said shaft from said first end to said second end, wherein said second blade spirals around said shaft from said first end to said second end, wherein said third blade spirals around said shaft from said first end to said second end.
18. The poultry chiller of claim 17 , wherein said tank comprises an auger section and an unloader section.
19. The poultry chiller of claim 18 , wherein said auger section of said tank has a first end and a second end, wherein said auger section of said tank comprises an inner wall surface, wherein said auger section of said tank comprises said auger, wherein said first blade, said second blade, and said inner wall surface of said tank forms a first spiral pocket that extends from said first end of said auger section to said second end of said auger section, wherein said second blade, said third blade, and said inner wall surface of said tank forms a second spiral pocket that extends from said first end of said auger section to said second end of said auger section, wherein said third blade, said first blade, and said inner wall surface of said tank forms a third spiral pocket that extends from said first end of said auger section to said second end of said auger section.
20. The poultry chiller of claim 19 , wherein a poultry carcass in said first pocket is blocked from passing from said first pocket to said second pocket.
21. The poultry chiller of claim 19 , wherein a poultry carcass in said first pocket is blocked from passing from said first pocket to said third pocket.
22. The poultry chiller of claim 18 , wherein said poultry chiller is in communication with a control system, wherein said control system determines the amount of poultry carcasses to be removed from said poultry chiller by an unloader in said unloader section of said tank.
23. The poultry chiller of claim 17 , wherein said first blade has a long pitch, wherein said long pitch is operable to force a poultry carcass to rotate around said shaft when said auger rotates.
24. The poultry chiller of claim 17 , wherein said first blade, said second blade, and said third blade are substantially equally distant from one another around said shaft.
25. The poultry chiller of claim 17 , wherein said first blade spirals at least one full revolution around said shaft, wherein said second blade spirals at least one full revolution around said shaft, wherein said third blade spirals at least one full revolution around said shaft.
