Twin Screw Press for Meat Bone Meal Plant / Pet Food Production Plant

Press Structure and Working Principle

The twin screw press is an important role in wet pressing method of fishmeal production. It consists of main body, double-screw, screen holder and power devicet. It squeezes after cooker cooking the fish material ,and turn out  is fish cake  and fish liquid.

The twin screw press is carried out in a press chamber consisting of two hollow interlocked cylinders. The cylinder wall is made of heavily supported strainer plates made from stainless steel. The two press screws have tapered shafts and the screw pitch varies so that the pitch, and thus the flight distance, is greatest at the thin end of the shafts. The screws rotate in opposite senses. The material is fed in at the end where the shafts are thinner, and is carried towards the end where they are thicker. As can be seen, the space for the material gradually reduces and, to compensate, liquid is pressed out through the strainer plates surrounding the screws.
 

Twin Screw Operation

The twin screw presses are easy to operate, and the performance is easy to monitor. The closed design ensures effective deodorisation, the combination of electronic control and instrumentation enables automatic safeguarding against overload. The variable screw speed provides for the flexibility necessary to cope with various raw materials and capacities.
