Super centrifuge for Virgin coconut oil Production

[Guest guest]

Separation of virgin coconut oil form coconut milk.

Separation of Oil from coconut emulsion (milk) is

certainly feasible, as the emulsion would resolve

itself under a high centrifugal force of 20000-x g in

the HG-16 Tubular Bowl Centrifuge into a free oil

phase, an aqueous phase and the protein phase.

We take this opportunity to brief you on the design

and working of the super centrifuge offered by us:

The Super Centrifuge is vertical model tubular bowl

centrifuge, which rotates up o 17000 rpm and thereby

generating centrifugal force 20000 times gravity

force.

The mixture of two immiscible liquid (say oil and

water) having difference in specific gravity is feed

into the rotating bowl through stationery feed nozzle

at the bottom. Due to extremely high centrifugal

force, the two liquids will get separated and will

form the concentric cylindrical layers of liquid.

Heavy liquid (water) held near to the wall of

centrifuge bowl and lighter liquid (oil) forming the

inner concentric layer.

These two layers gets continuously get displace by

incoming liquid and then comes out separately through

suitably designed covers.

Suspended solids if present get settled against the

bowl wall under the high centrifugal force. The solid

holding volume of our HG-16 model Super Centrifuge is

5.25 liters. It means that once this much volume of

solids is deposited inside the bowl of centrifuge the

solids are to be removed manually after stopping the

machine. Stopping the machine, cleaning the bowl and

restarting takes about 20-25 minutes

The process conditions such as emulsion temperature,

pH etc upstream of the HG-16 centrifuge would however,

determine the ultimate moisture content in the free

oil. Our machines can guarantee a moisture level below

0.1%

Model HG-16 Tubular Bowl Centrifuge would be expected

to operate satisfactorily at ~100 liters /hr.

But its rated Capacity for coconut milk is 200 LPH,

emulsion feed rate to give, a practically acceptable

performance.

As such HG-16 model super centrifuge is a continuous

separator of the two liquid phases.

We trust the information given is in line with your

requirement.
