Screw Press | Fish Squeezing Machine

This fish squeezing machine is the common type of screw press for dewatering of the cooked fish pieces and separating the fish meal and the fish oil liquid. The screw-type fish dewatering machine is a very important piece of equipment for making the fish meal in the fishmeal production line. This fish processing machine is common used in the wet processing method for fishmeal making.

Brief description of fish squeezing machine

The cooked fish juicer machine also named screw press juicer machine or the dewatering machine, except using in the fish powder production line, it can also be widely used in many fields, such as vegetables and fruits juice making, kitchen waste and sludge dewatering, sawdust and vinasse dewatering and so on.

During the fish processing line, the purpose of the fish press machine is to squeeze out as much liquid as possible from the stewed fish. This is important not only to improve the fish oil yield and the quality of the fish meal but also to reduce the moisture content of the wet fishmeal as far as possible, thereby reducing the fuel consumption of the fishmeal dryer machine and increasing its capacity.

Main structure of screw press for cooked fish dewatering

With the reasonable and compact structure, this screw press is mainly composed of the fish pieces inlet, the inner twin-screw structure, the screen mesh, the frame body, the stainless steel outer shell, geared motor, and the electrical control system. All these parts can be made of the high-quality SUS 304 stainless steel to ensure its long service life. The screen mesh for sieving out the liquids can be replaced with different specifications of the sieve holes. Besides, it can be set with a forced feed plate device for fast feeding, which can move the spiral forward, speed up the feeding, and prevent the counter and spiral from slipping.

How does the fish squeezing machine work?

When this fish press machine working, we can put the fish pieces into its inlet manually or by using a screw conveyor for feeding. Then the small inner screw structure will push the materials forward for squeezing. The extrusion structure of the machine is a series of two helices on a shaft, which runs in opposite directions when pressing the materials.

Amount of the liquids will flow out from the screen holes quickly and can be collected by the special container, which is rich in fish oil and fish protein so that can be further processed with the fish oil production line. The wet fish slags will be delivered forward and discharged from the outlet.

Main features of the automatic fish dewatering machine

1. The performance of the screw press is largely determined by the profile and the compression ratio of the screws, that is, the ratio between the flight volumes of the inlet and outlet flights. The pressing speed and pressing pressure of this fish dewatering machine can be adjusted for deep pressing of the fishmeal.
2. The screw press juicer machine uses a double-screw extrusion structure, and the press dewatering and degreasing effect is very good in the fishmeal production.
3. This equipment is a one-piece construction that is easy to install, use and move. In addition, the material of the machine is made of 304 stainless steel, which has good corrosion resistance.
4. The screw press adopts brand-name speed-regulating motor and has a wide speed range, which can be applied to the pressing of different kinds of fish. When the machine is working, it has low noise and long service life.
