Screw press

Screw press working principle is broken pulp, juice, skin through the hopper into the spiral juicer, because the spiral along the slag outlet direction of the bottom diameter gradually increased and the pitch gradually reduced, when the material is pushed forward by the spiral, because the volume of the spiral cavity is reduced, the formation of the material press.  The rotation direction of the spiral spindle is counterclockwise when viewed from the hopper to the slag trough.  The raw material is added into the hopper and pressed under the advance of the screw. The squeezed juice flows into the juice holder at the bottom through the filter, while the waste is discharged through the annular gap formed between the screw and the cone part of the pressure regulator. The size of the gap can be adjusted by the axial movement of the pressure regulator head.  Turn the handwheel by hand wheel bearing can change head and the clearance between the spiral cone voltage regulator, changing the resistance of slag discharge, can change the rate of slag, but if the gap is too small, the strong pressure, part of slag particles with juice by filter out, although the juice increased, but the quality of juice relative decline, the size of the gap should be depending on the user's specific technical requirements.  In order to achieve automatic separation of juice and slag.
