An apparatus for quantitatively extruding food material.

摘要

Food material is introduced into a space (27) formed between the periphery of a drum (9) and the wall of a housing (7). The drum has an inner chamber (31) between its inner wall and the periphery of a cam (19). A pair of blades (15) is inserted into slits (13) formed on the drum so as to form a compartment on the outside of the drum and a compartment in the inner chamber (21). The dimensions of the outer compartment decrease towards the exit port (23), while those of the inner compartment increase, so a pressure differential is established and any air in the material is drawn into the inner chamber via a recess (17) on the trailing surface of the blade (15). Material of a uniform quantity and density, and that has no air entrainment, is thus extruded from the exit port.
