How does a screw press press the fruit and vegetable?

The screw press mainly uses the pressing of the juice of the fruit and vegetable juice. When the material is pushed forward, the volume of the spiral cavity is reduced, and the material is pressed.

The raw material is added to the feed hopper and pressed under the spiral propulsion. The pressing occupation is filtered through the juicer flowing into the bottom, and the fertilizer flows through the filter into the bottom of the juicer, and the fertilizer is passed through the screw of the screw machine. The replacement gap formed between the shaped portions is eliminated, and the movement of the pressure regulating head in the axial direction can adjust the size of the gap and adjust the juice rate.

The broken pulp, juice and skin enter the spiral juicer through the feeding hopper. The pitch of the bottom diameter decreases gradually as the spiral increases along the direction of the slag outlet. When the material is spirally advanced, the volume of the spiral cavity is reduced. , open the pressing of the material.

The direction of rotation of the spiral is seen from the direction of the slag tank of the feed hopper, which is counterclockwise.

The raw material is added to the feed hopper, pressed under the advancement of the spiral, and the pressed juice flows through the filter into the bottom of the juicer, and the waste is discharged through the loop space formed between the spiral and the tapered portion of the pressure regulation. The pressure head moves axially and is directly controlled by the hydraulic system. Adjusting the pressure of the hydraulic system, that is, adjusting the resistance of the slag discharge, the juice rate can be changed. However, if the hydraulic system pressure is too large, under strong extrusion, some of the slag particles will be squeezed out together with the juice through the small filter screen. Although the juice is increased, the quality of the juice is relatively reduced, and the pressure of the hydraulic system should be determined according to the specific process requirements of the user, so as to achieve the purpose of automatic separation of the juice and the slag.
