The whole process mainly includes the following processes:

1). Degumming and Water Washing, Drying Process

2). Bleaching Process

3). Deacidification and Deodorization Process

Process Description of Palm Oil Refinery Plant:

1). Degumming and Water Washing, Drying Process

The crude oil of palm oil refining machine is filtered by bag type filter to remove the impurity. The filtered oil , metered by flowmeter, is pumped to degumming section.After heating to the required temperature, the oil is mixed with phosphoric acid. Then sent to the condition tank. The reaction time is around 20-90 minutes according to the quality of oil.

This processing section of edible oil refinery plant adopts high effective mixer which can divide the phosphoric acid into particle(10um). This improves the contact area between phosphoric acid and non-hydratable phospholipids which improve the transform from non-hydratable phospholipids to hydratable phospholipids.
The process of heat exchange between dryed oil and crude oil saves the energy.The drying processing is reaction in vacuum device which protect the oil from the air(oxidation)
The whole degumming process is controllable in controlling room (such as temperature and flow meter).

2). Bleaching Process of Palm Oil Refining Machine

The bleaching earth is fed by oil flow meter,time and ration. Which can ignore the missing feeding situation.The bleaching time is adjustable which is advanced than traditional processing. This can calculate the time of bleaching.
The heated degummed oil is sent to mixer. The mixed bleaching earth is also sent to mixer. the mixed oil is sent to bleacher from mixer. The bleaching time is about 30-60 minutes. The oil is sent to filter (double filter) to remove the spent earth. The oil is pumped to drying tank to remove the moisture. The temperature during whole bleaching processing is adjustable.The filter system can realize automatic oil inlet , oil circle, filtering, spent earth discharge etc.

The bleaching section of edible oil refinery plant adopts the device which can catch the odor (using recycle water). This way can ignore the odor pollution.
