Continuous Stainless Steel Decanter Centrifugal Fish Oil Separator Processing Machine

Product Description:

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.

We have more than 30 customers in Gambia, Mauritania and Senegal for fish oil and fish meal .

Tenchical parameters

working principle

Basic principle of horizontalscroll discharge centrifuges (namely decanter centrifuges): the light liquid, heavy liquid and solid (dregs) in the mixed

liquid (suspension) have different densities and are immiscible, and any two or three phases therein are then under different centrifugal forces in

the centrifugal force field, resulting in different settling velocities, then achieving thepurpose of separation, layering or settling the

solid-phase particles in the liquid.
 

After entering into the high-speed turning drum,the solid-phase particles in the mixed liquid run and settle  on the drum wallunder the action of

greatest centrifugal force; the light liquid settles at the innermost  place of the drum under minimum centrifugal force; and the heavy liquid settles

in the middle (this phase exists in case of three-phase separation or does not exists in case of two phases); same as the drum’s

turning direction, a screw feeder also turns at a high speed, and a constant speed difference is generated by the differential mechanism; the solid-

phase particles settled on the drum wall are then fed by the screw feeder to the solid outletof the drum, and the light phase and heavy phase (this

phase exists in case of three-phase separation or does not exists in case of two phases) are then separated out of different outlets.

When used for two-phase separation, the machine is called two-phase decanter centrifuge (also called horizontal scroll centrifuge), and the

machine used for three-phase separation is called three-phase decanter centrifuge. In our decanter centrifuges, the light liquid is exhausted by

gravity force, and the heavy liquid is discharged by the centrifugal force

Technical Parameters

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.
