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. 

Main feature:

1. Two motor, two frequency inverter drive system, realize differential speed stepless regulation and energy return.
2. Spiral stoker blades: Surfacing welding tungsten carbide grinding.
3. Drum cone cylinder material outlet: Replaceable wear resistant, corrosion resistant ceramic alloy bushing.
4. Main bearing: ABB 
5. Main sealing parts: Taiwan SOG, material is Nitrile butadiene rubber
6. Electrical protection: overload, phase loss, torque protection
7. Main and vice inverter use common DC bus, vice motor's function is generating electricity ( save electricity)
8. PLC remote control.

Working Principle:

Two Phases Separation Principle:
The feed suspension is introduced through an inlet pipe into the feed zone of the conveyor where it is accelerated and directed into the interior of the bowl. The settled solids are conveyed axially towards the small end of the bowl by means of the screw conveyor, which rotates at a slightly different speed than the bowl. On the way to the discharge ports the solids are lifted out of the pond up along the dry beach. The solids are finally discharged from the bowl through the discharge ports into the collecting chamber of the casing that surrounds the bowl. From there the solids are removed by gravity through the outlet funnel. The liquid phase forming a hollow cylinder due to the centrifugal force, and flows towards the large end of the bowl. There the liquid overflows adjustable plate dams into the centrate chamber of the casing and is discharged by gravity.
Three Phases Separation Principle:
The light liquid phase is discharged into the casing through radial holes in the large end hub. The heavy liquid phase is discharged through axial holes in the large end hub. The liquid radius for the light liquid phase is smaller than the radius for the heavy liquid phase. The liquid level is controlled by plate dams. In order to prevent the light liquid phase from leaving the bowl through the heavy liquid phase outlet, a separating plate is placed on the inside of the large end hub. The heavy liquid phase has to pass under the separating plate before being discharged into the casing. The liquid radius for the heavy liquid phase is controlled by plate dams. The solids are discharged in the normal way.
