Industrial Scale Decanter Fish Oil And Fish Meal Separator ISO
Certification
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.
The technological procedure of Three-phase Solid-bowl Centrifuge:
The fish water after fish rolling flows into the temporary storage
tank, charged by pump or high level tank, before which the fish
water shall be
heated to 85-90 degrees by steam heater or electric heater, and
then enters to the three-phase solid-bowel scroll centrifuge to be
separated; The
fish scraps, fish oil and waste water are separated for one time.
Fish oil is canned through steam or other heating approaches, and
the waste
water is sent to the dryer for evaporation through pumps, while the
fish scraps are also sent to the dryer, processing into fishmeal by
the
conveyer.
We have more than 30 customers in Gambia, Mauritania and Senegal
for fish oil and fish meal .

Application:
Currently, our three-phase decanter centrifuges are used in the
separation of olive oil , soybean oil , oils,
water and slags / dregs in the coal tar industry, the petrochemical
industry, the fish powder industry, the swill
oil industry, the electrolytic copper industry, and the waste
scraps in the slaughter houses.
