Screw shafts are widely used in today’s juicers, not only for juicers, but also for stick making machines, quick freezers, rinsing machines, feeders, etc. Screw shafts have many applications in juicers. It can be said that whether it is a domestic juicer or a large juicer, the design of the screw shaft is a key component of the juicer, and the design of the screw shaft is also an important factor affecting the juice output.

In the screw juicer, the left end of the screw shaft is supported on the rolling bearing seat, and the right end is supported on the handwheel bearing seat. The motor is driven by a pair of pulleys to drive the screw shaft. The screw shaft rotates clockwise in the direction of the slag outlet, the diameter of the furnace bottom gradually increases, and the screw pitch gradually decreases. When the material is pushed by the screw shaft, the screw cavity gradually narrows, thereby forming a squeeze of the material. This is the role of the screw shaft in the screw juicer.
