Fish Meal & Oil Process

The fish is first cleaned with fresh water in a tank and are put into a hopper of the first conveyor, which carries the fish to a continuous cooker. The fish is steam cooked in the cooker. The cooker then empties the cooked fish into a Double Screw Press, which squeezes the steamed fish. The discharged sticky fluid and its solids come out through two different outlets. The sticky liquid is pumped to a tank for settling. The water content settles down due to its higher specific gravity and oil that floats above is pumped out. The settled oil is thereafter pumped into barrels. The fish cake is then carried to the Steam Tube Dryer through the second conveyor to the Lump brake then carries to the Dryer with third Conveyor and it is dried through Steam Tube Drier. The dried fish meal is then carried through the fourth conveyor to the Screener. After Screening dried fish meal is carried to the Hammer Mill through the Fifth conveyor. The cake is hammered to the required size and then it is packed in polythene lined jute bags. Since the manufacturing process is automatic it’s very simple to operate. The entire plant can be managed by seven labour force and one office staff per shift.

Fish meal is a valuable feeding material with high contents of digestible proteins. Fish meal is given as supplementary food to increase production of meat or eggs. Since the diet of domestic and poultry animals is often deficient in proteins and vitamins, fish meal has become very popular as it provides important nutrients for poultry, cattle and prawns. The Fishmeal output is 2 tons for an input of 10 tons of fresh fish.

It is very much used in soap, leather and paint industry and also in steel plants. The out put is one ton for an input of 10 tons of fresh fish.
