1. Fishmeal Processing Line consists of Cooking-Pressing-Decanting-Drying-Cooling-Grindering and Packing;
2.The fish passes through a electrical magnet to remove iron like fish hooks.The raw material is cooked in a steam cooker where the protein of the mass is coagulated, the fish oil is liberated.The mass from the cooker goes to twim screw press to squeeze out as much liquid as possible from the solid phase.
3.After pressing, we get press cake and press liquor.The sludge is recovered in a decanter and then dryed in dryer after mixed with press cake.The liquid after decanter is treated in a oil separator. In the high speed centrifuge, fish oil is separated. the stickwater goes to evaporator.
4. The stickwater is good for fishmeal,in Fishmeal Processing Line , the stickwater after evaporator,its concentrate continously by the waste vapor from the dryer and cooker.The press cake, sludge and stickwater concentrate is mixed together and is dryed in the disc dryer.
5.After drying process, the fish meal have to be cooled to room temperature by a cooler.
Usually the fish meal shall be grindered to fine particles before packing. After grinding, the fish meal shall be transported by an air-cooling screw conveyor before it is packed in a packing tank.
