The principle of Apple crushing juicer is that the crushed pulp, juice and skin enter the screw Juicer through the feed hopper, because the screw gradually increases the bottom diameter along the direction of the slag outlet and the screw pitch gradually decreases. When the material is pushed by the screw, the volume of the screw cavity is reduced, forming the pressing of the material. The rolling direction of the screw spindle is counter clockwise from the hopper to the slag groove. The material enters into the feeding hopper and is pressed under the push of the screw. The squeezed juice flows into the juice container at the bottom through the filter screen, while the waste material is discharged through the annular space formed between the screw and the pressure regulating conical part. The size of the space can be adjusted by moving the pressure regulating head along the axial direction. The size of the empty space between the pressure regulator and the spiral cone surface can be changed by rolling the hand wheel bearing seat hand wheel, that is, the resistance of slag discharge can be adjusted, and the slag discharge rate can be changed. However, if the empty space is too small, under strong extrusion, some slag particles and juice will be extruded through the filter screen together. Although the juice is added, the quality of the juice is relatively reduced. The size of the empty space should depend on the user's detailed process requirements It's settled. And then reach the intention that juice and dregs take the initiative to leave.
