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.
