Abstract
A multi-purpose vacuum screw loader deaerates meat emulsions and meat chunk mixtures, and loads the deaerated product to a forming or casing station. A sealed vacuumized hopper has a lowermost auger for force-feeding processed product through an outlet in the bottom of the hopper to a positive displacement pump in communication with the next processing station. An agitator overlying the auger within the hopper serves to expose air pockets in the meat emulsion for more complete removal of entrained air. An inlet in the hopper positioned well above the normal product level is particularly sized to form a free-falling, film-like flow of product as the hopper is loaded whereby to expose maximum product surface area to the vacuum environment.
