Working principle and structure:

Screw press, the working process is: the conveying screw pushes the material entering the tank to the pressing screw, the pitch of the pressing screw is reduced and the shaft diameter is increased, and under the action of the screen wall and the cone resistance, the material is contained The liquid (fruit juice) is squeezed out. The extruded liquid flows out of the mesh and is concentrated in the juice hopper.

The pomace after pressing is discharged outside the machine through the end of the sieve cylinder and the cone, and a spring is arranged at the rear of the cone. By adjusting the preloading force and position of the spring, the displacement resistance and the size of the slag opening can be changed. Adjust the dryness and wetness of the press.

The feeding box, sieve cylinder and spiral of the machine are made of high quality acid and alkali resistant 304 stainless steel.

Equipment composition:

The equipment mainly consists of a frame, a feeding part, a pressing part, a transmission part and an electric control part. In addition to the powerful feeding device and the anti-backing device, the single screw press is divided into three parts: the feeding screw, the pressing screw and the pressing screw.

Equipment advantages:

It has the characteristics of high strength, large bearing pressure, no deformation, no clogging, corrosion resistance, wear resistance, no slippage, convenient maintenance and long service life. The slag outlet can change the pressure exerted on the material by adjusting the spring pressure or the oil pressure, thereby adjusting the dryness and wetness of the slag discharge, and the pressing effect thereof may have a certain difference depending on the materials.

Compared with the horizontal screw machine, plate and frame filter press and vacuum suction filter, the equipment has a high cost performance. The water content of the material after dewatering by the machine is about 60% (depending on the material).
