ABSTRACT:
Baker's dough moves from feed hopper (21) through dough inlet opening (25) into auger housing (19). Reduced pressure is maintained in the auger housing by gas exhaust port (28) and vacuum pump (27). The depth and amplitude of the helical cavity (31) in the pumping section (34) of the auger (20) is greater than the depth and amplitude of the helical cavity (33) in the gas exhaust section (35) of the auger, so that more resistance is applied by the interior cylindrical surface (29) of the auger housing to the dough in the gas exhaust section (35) than in the pumping section (34). Therefore, the dough does not clog the gas exhaust port, allowing increased vacuum to be applied to the housing, thereby firmly drawing dough to the auger. Additionally, transverse dough feed and transverse dough exhaust with respect to length of the auger tends to reduce the tendency of the dough to move circumferentially with the rotation of the auger, thereby enhancing the pumping efficiency of the auger.
