Decoloring Process

The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions.

Under negative pressure, the mechanical mixing method combined with steam mixing will improve the

decoloring effect.The degummed oil firstly enters into the heater to be heated to the appropriate temperature

(110°C), and then goes to the bleaching earth mixing tank. The bleaching earth is delivered from the low

bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is

interlockingly controlled with the oil.

Decoloring Process Features

1. The oil fully contacting with the decolorant can improve the decolorization efficiency and reduce the usage

of decolorant;

2. The continuous and uniform material flows will balance the decoloring time and avoid the recovery of grease

oxidation and acid value.

3. The special mixing structure of decoloring tower won't cause the material dead area, which can avoid the

adsorbent sedimentation and pipe blockage.

4. The continuous airtight efficient filtration equipment has realized the automation of cake discharge and reduced

the labor intensity.

5. The advanced drying technology can reduce the oil content in filter cake

Deodorizing Process

The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, and next

goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C)

and then enters the deodorization tower. The upper layer of combined deodorization tower is the packing

structure which is mainly used to remove the odor producing components such as free fatty acid (FFA);

the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the

peroxide value of the oil to zero.
