US Patent 9271509 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.
