PRESS-SEPARATING INEDIBLE PARTS FROM MEATS

摘要

A method and apparatus for separating the fat and protein constituents of the flesh of warm- blooded animals and fish from non- edible parts such as sinews, skin and bones comprises passing the flesh between an endlessly rotating, highly elastic pressure belt (4) and a rotating perforated drum (1), the pressure being varied during the passage as the studs (9) on the belt are narrower than the grooves (7) on pressure roller (5) causing increased pressure at back surface of the studs and decreased pressure at front of the grooves. Pressure between belt and drum can be varied by altering axis (6) of the rotating roller (5).
