Hydraulic press of the cake: Due to limitations hydraulic press itself squeezed closed bore , the piston -cylinder extrusion pressure by squeezing oil, a disc-shaped cake , and oil crops , depending on the different models of the diameter pie vary with the thickness of the disc .
????Screw press of machine pellet and row of the press , regardless of the kind of crushing multi- way press the bread into the shape of a palm-sized sheet , the thickness of the price adjustment based on the user's own needs , that is, if you want a high rate of oil cake can adjusted 1 ~ 3mm, pellet press user needs is cake, then the cake thickness can be adjusted a little thick . But the oil yield would be reduced accordingly . This is a screw press cake and regulation of the principle .
