Twin screw press

Discription:

For pressing liquids from cooked fish or meat in a wet rendering process.
The twin screw press ensures eficient mechanical dewatering and reduction of the oilfat content, which improves processing and increases the energy saving potential. The twin screw press attains a condition of high compression resulting ina low moisture and oilfat content in the press cake.

The press consists of two interlocking screws enclosed by a strainer shell and surrounded by a cover. The flights’ geometry can be cylindrical or biconical depending on the performance required and the type of material being processed. The screws rotate in opposite directions, preventing the material from rotating with the screws. The strainer cage consists of perforated stainless steel plates surrounded by mild steel supporting plates, which are supported by heavy steel bridges.The strainer plate holes vary in size of the press from inlet to the outlet from 5 to 1.

The twin screwpress can be dlivered as a conical or a cyindrica press
One of the advantages of the conical type is that the flights of one screwreaches almostinto the core of the other screw.The result is minimum slip in the press and a more uniform press cake.
