Three-Phase Horizontal Decanter Centrifuge for Extraction of Fish Oil in Fishmeal Industry

Technology of Extraction of Fish Oil in Fishmeal Industry

Fresh fish are sent by spiral conveyer into the cooking machine for stewing, and then delivered to the rolling mill after thoroughly stewed, and the fishmeal is produced after rolled fish are dried in a dryer. There are oil water and fish scraps in the fish soup, after being extracted, if the fish oil and fish scraps are sent back to the dryer, it is called through-dewatering, if they are not sent back to be evaporated, it is called half-dewatering. As normal fishmeal plants do not have sewage treatment device, considering the environmental requirement, most of them adopts the through-dewatering method. There are various technologies in extracting fish scraps and fish oil from the fish soup, among which a relatively traditional one is to extract fish oil by several settling ponds, another one is to extract fish scraps by two-phase Horizontal Decanter Centrifuge and then extract the fish oil by disc stack centrifuge, another one is to extract the fish scraps and fish oil for one time by three-phase Horizontal Decanter Centrifuge. 

Separation takes place in a horizontal cylindrical bowl equipped with a scroll conveyor. 

The processing material is fed into the bowl through a stationery inlet tube and is smoothly 

accelerated in the accelerate chamber. Centrifugal forces cause instant sedimentation of the solids 

on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different 

speed, thus moving the solids towards the conical end of the bowl.
