Single screw continuous presses

All models are actioned by a threephase electric motor. The rotation speed of the screw, obtained by a gearbox, is between 11 and 12 Rpm for models 250 and 300, while for models 350 and 400 a speed variator reduces even more the rotation of the screw from 3 to 9 Rpm. All parts in contact with the product (cage cover, cage, screw conveyor, hopper) are made of stainless steel, except for the the screw and the maltese cross which are mode of antiacid bronze. The cage is made of longitudinal trapezoidal shaped bars with a minimun slot of 0.5 mm large. The pressure regulation of the outgoing mass of husk is made manually by a handwheel.
