AN APPARATUS FOR QUANTITATIVELY EXTRUDING FOOD MATERIAL

摘要

Apparatus for extruding food material whereby the material is introduced into a space (27) formed between the periphery of a drum (9) and the side wall of a housing (7). The drum has an inner chamber (31) between its inner wall and the periphery of a cam (19). Blades (15) are inserted into slits (13) in the drum (9) periphery, and adjacent pairs of blades (15) form compartments in the sections in the outside of the drum (19) as well as in the inner chamber (31). Since the dimensions of the compartments in each section decrease toward the exit ports (23) while the dimensions of the compartment in the inner chamber (31) increases, the pressure in the outer compartments becomes higher than that of the inner chamber. Thus the air in the material is drawn out of the outer compartments via a path formed between the recess (17) on the trailing surface of each blade (15) and the wall of each slit (13).
