China professional supplier cooking oil processing machine

The main processing of oil refining machine

Crude oil → Degumming→ Deacidification → Bleaching→ Frame filter→ Deodorization →Dewaxing →Leaf filter

Detailed instruction of main process:

1. Dedumming section :The system is designed to degum crude oil.

The Degumming System will generally produce oil with lower levels of residual phosphatides

and less residual pigments and therefore require less bleaching earth in bleaching as well as help

generate finished deodorized oil with a lighter color and longer shelf life.

2.Bleaching Section

The feed oil (acid conditioned, degummed / neutralized & washed) enters the Bleaching Section

via a Bleaching heater where the oil is heated up to Bleaching temperature and discharged into

the slurry mixer. A valve dosing system proportions Bleaching Section. The earth is introduced

under the oil spray in the mixing chamber for improved mixing so that earth does not enter the

Bleaching Section. The earth adsorbs any residual gums and soap as well as trace metals, color

bodies and other polar impurities. The Bleaching Section has multiple agitated compartments and

operates under vacuum to ensure complete moisture and air removal.

3.Deodorisation section

Deodorisation Oil Mill Machinery is continuously pumped from the Feed Tank by the Deareator

Feed Pump. The Deodorisation Oil Mill Machinery is pre-heated in the Deaerating Economizer by outgoing deodorized oil followed by the Deaerating

Heater (if necessary) before entering the Deaerator. The vessel is under full vacuum, so that

residual air is reduced to an absolute minimum. The Deodorisation Oil Mill Machinery is heated

to full processing temperature in the Vacuum Heater by thermal fluid from the Thermal Oil Heater.

A portion of the free fatty acids in the oil will be flashed off as the oil temperature increases.

The oil quality outcome:

1. Grade one for salad oil

2. Grade two for high quality cooking oil

3. Mixture and volatile≤0.25%.

4. Impurity≤0.2%.

5. AV (mgKOH/g)≤7

6. FFA≤3.5%.
