In batch oil refinery process or cooking oil refinery process, a measured amount of oils is processed in sequence of neutralizing, bleaching & deodorizing.

For plants capability from 5 to 25 tons per day, batch process is advisable being low cost and straightforward to function.

Crude oil obtained from expellers or solvent extraction plant contains overseas impurities corresponding to mucilage, gums, coloured & unfiltered matter from the seed. Also Free Fatty Acids (F.F.A.) which are likely to deteriorate the oil on storage, thus making it unfit for edible function. The batch refining course of consists of following section :

– Neutralizing / Degumming
– Bleaching Part
– Deodorizing Section.

First Stage of Refining is to Remove Free Fatty Acids(F.F.A.) wih caustic Soda Treatment referred to as Neutralizing Process Thereafter further processed in the bleaching part beneath vacuum and handled with bleaching earth and activated carbon for eradicating colour .Lastly will probably be Deodorized below excessive vacuum and high temperature to remove the odour from the oil. The Edible obtained in a batch refinery is of fine quality meeting all requirement
of International Customary. However in case of Sunflower and rice bran oil, there is one more technique of Dewaxing after bleaching Process.

The tools concerned are Neutralizer, Bleacher, Deodorizer, Heat Exchanger, Excessive & low vacuum tools & Filters. Shreeji plant with batch process have been operating at number of locations, processing number of vegetable oils.


Fundamental strategy of refining is same in each batch & continuous refinery. Only difference is as a substitute of a measured batch, crude oil is processed continuously with constant stream of move. In between required utilities & chemicals are added continuously in measured amount. Crude oil from obtained from expellers, solvent extraction plant comprises foreign impurities resembling mucilage, gums and unfiltered proteinous matter from the seed. It also comprises gums which making it unfit for edible
purpose. Fundamental phases of the method are as below:

– Nutralizing
– Bleaching
– Dewaxing & Deodorizing.


The crude oil is pumped to Neutraliser from oil mill or storage tank & first it’s handled with weak answer of phosphoric acid or different appropriate degumming agent for removing gums.
– Thereafter oil is additional treated with measured amount of alkali (NaoH) relying upon free fatty acid (F.F.A.) in crude oil. On this course of cleaning soap will probably be separated.
– Next course of is scorching water wash to the oil to take away traces of cleaning soap particle &
free alkali.
– The oil obtained shall be mild in colour, free from soap inventory & known as as washed
Neutralised Oil.


On this course of excess color from the oil is eliminated. The neutralized washed oil is pumped into the Bleacher vessel working under vacuum.
– The oil is first heated to take away excess moisture and thereafter will probably be handled with predetermined amount of bleaching earth & activated carbon.
– Thereafter the oil will move by means of a filter media (Strain leaf / Filter press) to separate spent bleach earth and bleached oil.
– The oil will cross obtained after bleaching course of is light in colour & look of oil might be clear golden in colour


A very simple requirement of this process is to supply Clear, Brilliant refined oil and to fulfill certain specs of Cloud Point.

Sunflower and Rice Bran oil normally contain waxes compared to different oil. Due to this fact these oils are subjected to de-waxing course of referred to as Winterisation Plant, to take away waxes from oil and to produce sparkling good quality edible oils.

To take away the wax, the oil is first processed in Crystaliser the place it is cooled by Chilled water circulation. Where the wax is converted into crystal form and there after this will likely be cross via the filteration course of. Now, the wax is separated and the de-waxed oil is collected

SHREEJI know-how gives you an arrangement; you have been looking for since lengthy. Our Crystalliser is Geometrically Designed for Uniform Cooling and effective Nuclei progress of particle.


This course of removes odour from the oil to improve the standard and self-life of oil.
– The bleached oil is charged to deodorizer straight or by way of heat exchanger and is heated at high temperature and in addition underneath high vacuum in deodorizer vessel to acquire odourless clear oil.
– As soon as the method cycle is full the oil obtained might be odourless & mild in color.
– After cooling it should move by means of polishing filter to obtained sparkling light colour & odourless oil for packing, which will be used as edible oil.


SHREEJI’s know-how offers a Low Operating Value Fractionation Plant which supplies excessive olien / mushy stearin yields at established control i.e. PLC (automation) for efficient working and reliability of the plant.

The separation of Stearin and Olien is constantly accomplished on Rotary Vacuum Drum Filter and its principle is simple, whereas Crystallization course of involves an ideal approach to develop and develop the particles measurement for easy clean separation of Stearin and Olien.


Hydrogenation which is also known as Fat Modification is exclusive three phase process system: Solid (Nickel Catalyst), Liquid (Oil) and Gasoline (Hydrogen). Additional a selective response, by bringing gas—hydrogen, liquid—oil to the solid—Ni Catalyst and this technological concept formalised an Engineering Design.
