A drier apparatus includes a cylindrical chamber in which a pair of screw conveyers each including a tubular shaft in which heat medium is able to flow, and carrier blades arranged on an outer surface of the tubular shaft is housed, a motor for rotating the screw conveyers, an input path connected to the cylindrical chamber at a proximal end of each of the screw conveyers, and an output path connected to the cylindrical chamber at a distal end of each of the screw conveyers. The input path and the output path include a device for opening and closing a path. Each of the screw conveyers includes a pair of tubular shafts arranged substantially in parallel with each other, and a plurality of semicircular carrier blades such that the carrier blades form a part of an imaginary spiral plane about the tubular shaft on an outer surface of the tubular shaft, the carrier blade being partially made of a material having a resistance to abrasion.

A poultry chiller includes a tank and an auger rotatably held in the tank. The auger includes a first auger section and a second auger section. The first auger section includes a first auger shaft and a first auger flight. The first auger flight includes a first helical portion on the first auger shaft and a first flight extension that extends away from the first helical portion. The second auger section includes a second auger shaft coupled to the first auger shaft and a second auger flight. The second auger flight includes a second helical portion on the second auger shaft and a second flight extension that extends away from the second helical portion. The chiller includes a hanger bearing assembly between the first and second auger sections and extending to an upper portion of the tank.
