Working Principle
The single-screw press dehydrator is characterized by a solitary screw, which provides continuous dewatering and efficient shredding capabilities.The raw material is fed into the screw press machine,and then the machine starts to work.As the screw rotates, it moves the material from the feeding hopper to the discharge end.During the process, the space gradually decreases while the pressure is increasing. The increasing pressure compresses the material against the screen, forcing the liquid to be separated from the solid particles.

How dose the screw press dewatering machine work?
This screw-type press dewatering machine is used for solid-liquid separation ,dehydration and reduction of waste material, which is a physical squeezing method. The raw material is fed into the screw press dewatering machine, and then the machine starts to work.As the screw rotates,it moves the material from the feeding hopper to the discharge end.During the process, the space gradually decreases while the pressure is increasing. The liquid is then squeezed out through the screen and drain though the drain pipe.The discharge speed and moisture content can be adjusted by the adjustment device in the front of the screw press dewatering machine to meet your specific needs.
Single screw press VS Twin screw press
Single screw press-The single screw press,also know as the continuous screw press,consist of a single helical screw rotating within a cylindrical barrel.This design is simple and suitable for a variety of fiber-rich vegetables and fruits in various industries，such as grapes,gingers,herbal residue，sugarcane and pulp.Additionally,it provides customers with cost-effective solutions for waste treatment and the dehydration of waste materials such as spent grains,agricultural waste,and more.
Twin screw press-When two parallel screws rotate in opposite directions, one screw pushes the material forward, while the other screw exerts pressure on the material against the screen, thereby facilitating the separation of the liquid from the solid particles.In general,we have found that a double screw press has two times the throughput capacity of a single screw press with the same screw diameter.However,a double screw press is more costly,but it has a higher capacity.On the other hand, a single screw press is cheaper,but it has a lower capacity and sieving efficiency.
