Palm oil is the world's second largest edible vegetable oil. Palm oil refining machine can be divided into intermittent palm oil refining machine, semi-continuous palm oil refining machine and fully continuous palm oil refining machine.

 

According to palm oil refining process, palm oil refining machine can be divided into palm oil chemical refining machine and palm oil physical refining machine.

 

According to palm oil refining processing capacity, palm oil refining machine can be divided into small 5-10 tons/day palm oil refining machine, medium-sized 20-50 tons/day palm oil refining machine, large-scale palm oil refining machine with a capacity of more than 100 tons/day.

 

According to material, there are general carbon steel plus stainless steel palm oil refining machine and all-stainless steel palm oil refining machine.

 

The purpose of palm oil refining machine is to remove impurities, to achieve the finished product oil standard. Palm oil refining process main is: Crude palm oil ➞ degumming ➞ neutralization ➞ decoloration ➞deodorization➞ fractionation.

 

1.    Crude oil filter

Buy back crude oil should be filtered suspended particles impurities and other impurities to the following production.

 

2. Degumming

Pump crude palm oil in, stir quickly, and use direct steam or thermal oil to heat in a coil heater. It is necessary to control the amount of water added, the water temperature and the speed of adding water. During this period, the peptidic impurities will slowly turn into floc. Batch and semi-continuous palm oil refining machine use precipitation separation, while fully continuous palm oil refining machine requires a centrifugal separator.

 

3. Deacidification

Add alkali to neutralize free fatty acids. Intermittent palm oil refining machine still uses the precipitation separation method, while semi-continuous refining and fully continuous palm oil refining equipment use the distillation method together with deodorization.

 

4. Decolorization

Vacuum inhale a certain amount of decolorizing agent (activated clay/activated carbon), continue stirring and heating for 25 minutes, and then pump the mixture into the filter to separate the oil and decolorizing agent.

 

5. Deodorization

Pump in the decolorized oil and heat it. When the oil temperature reaches above 100℃, direct steam is introduced to take away the odorous substances.
