According to different capacity and edible oil refining technology, the peanut oil refinery plant can be divided into batch type peanut oil refinery plant and continuous peanut oil refinery plant. Basic process of peanut oil refinery plant is same in both batch & continuous peanut oil refinery. They all includes degumming/neutralizing, bleaching & deodorizing.

Batch type peanut oil refinery plant introduction:

In batch peanut oil refinery process or vegetable oil refinery process, a measured quantity of oils is processed in sequence of neutralizing, bleaching & deodorizing. For peanut oil refinery plants capacity from 1 to 20 tons per day, batch type peanut oil refinery process is recommended being low cost and easy to operate.

Crude peanut oil obtained from peanut oil expellers or peanut oil solvent extraction plant contains foreign impurities such as mucilage, gums, coloured & unfiltered matter from the seed. Also Free Fatty Acids (F.F.A.) which tend to deteriorate the oil on storage, thus making it unfit for peanut purpose.

The batch type peanut oil refinery process consists of following section :
Neutralizing / Degumming
Bleaching
Deodorizing

First Stage of peanut oil refinery process is to Remove Free Fatty Acids(F.F.A.) wih caustic Soda Treatment called Neutralizing Process Thereafter further processed in the bleaching section under vacuum and treated with bleaching earth and activated carbon for removing colour .Finally it will be Deodorized under high vacuum and high temperature to remove the odour from the oil. The Peanut obtained in a batch type peanut oil refinery plant is of good quality meeting all requirement of International Standard. However in case of Sunflower and rice bran oil, there is one more process of Dewaxing after bleaching Process. The equipment involved are Neutralizer, Bleacher, Deodorizer, Heat Exchanger, High & low vacuum equipment & Filters. Henan Doing Company peanut oil refinery plant with batch type peanut oil refinery process have been operating at number of places, processing variety of vegetable oils.

Basic process of peanut oil refinery plant is same in both batch & continuous peanut oil refinery. Only difference is instead of a measured batch, crude peanut oil is processed continuously with constant stream of flow. In between required utilities & chemicals are added continuously in measured quantity. Crude peanut oil from obtained from cooking oil expellers, peanut oil solvent extraction plant contains foreign impurities such as mucilage, gums and unfiltered proteinous matter from the seed. It also contains gums which making it unfit for peanut purpose.

Basic stages of the continuous peanut oil refinery process are as below:
Neutralizing
Bleaching
Dewaxing & Deodorizing

Degumming and neutralization process:
The crude peanut oil is pumped to Neutraliser from peanut oil mill plant or storage tank & first it is treated with weak solution of phosphoric acid or other suitable degumming agent for removing gums.
Thereafter oil is further treated with measured quantity of alkali (NaoH) depending upon free fatty acid (F.F.A.) in crude oil. In this process soap will be separated.
Next process is hot water wash to the oil to remove traces of soap particle &free alkali.
The oil obtained will be light in colour, free from soap stock & called as washed Neutralised Oil.

Bleaching process:
In this process excess colour from the oil is removed. The neutralized washed oil is pumped into the Bleacher vessel operating under vacuum.
The oil is first heated to remove excess moisture and thereafter it will be treated with predetermined quantity of bleaching earth & activated carbon.
Thereafter the oil will pass through a filter media (Pressure leaf / Filter press) to separate spent bleach earth and bleached oil.
The oil will pass obtained after bleaching process is light in colour & appearance of oil will be clear golden in colour

Dewaxing and winterizing (fractionation) process:
A very simple requirement of this process is to produce Clear, Brilliant refined peanut oil and to meet certain specifications of Cloud Point.
Sunflower oil,  corn oil and Rice Bran oil normally contain waxes compared to other oil. Therefore these oils are subjected to de-waxing process called Winterization Plant, to remove waxes from oil and to produce sparkling good quality peanut oils.
To remove the wax, the oil is first processed in Crystaliser where it is cooled by Chilled water circulation. Where the wax is converted into crystal form and there after this will be pass through the filteration process. Now, the wax is separated and the de-waxed oil is collected.

Decolorizing process:
This process in continuous peanut oil refinery plant removes odour from the oil to improve the quality and self-life of oil.
The bleached oil is charged to deodorizer directly or through heat exchanger and is heated at high temperature and also under high vacuum in deodorizer vessel to obtain odourless clear oil.
Once the decolorization process cycle is complete the oil obtained will be odourless & light in colour.
After cooling it will pass through polishing filter to obtained sparkling light colour & odourless oil for packing, which will be used as peanut oil.
