The SEW Fat Screw Press provides highly effective mechanical extraction of the fat content from cooked and dried animal and poultry by-products, in a continuous flow. This enables you to achieve a hard cake with a low fat content. As the fat pass along the single conical screw, the fat is pressed out into the surrounding chamber, and the greaves are discharged as press cake. The fat  comes out into a collector trough, chamber strips to collection dish.
