Abstract
An apparatus for quantatively extruding food material is provided. In this apparatus the material is introduced into a space formed between the periphery of a drum and the side wall of a housing. The space is divided into sections defined by flanges, and thus the material is divided into portions and introduced into each section. The drum has an inner chamber between its inner wall and the periphery of a cam. Blades are inserted into slits in the drum periphery, and adjacent pairs of blades form compartments in the sections in the outside of the drum as well as in the inner chamber. The apparatus has a plurality of exit ports communicating with the respective sections. Since the dimensions of the compartments in each section decrease toward the exit ports, while the dimensions of the compartment in the inner chamber increased, 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 on the trailing surface of each blade and the wall of each slit. As a result, material of a uniform quantity is extruded from each exit port.
