Cooking Oil Refinery Plant
In batch oil refinery process or cooking oil refinery process, a measured quantity of oils is processed in sequence of neutralizing,
bleaching & deodorizing.
Crude oil obtained from expellers or solvent extraction plant contains
foreign impurities such as mucilage, gums, coloured & unfiltered
proteinous matter from the seed. Also Free Fatty Acids (F.F.A.) which
tend to deteriorate the oil on storage, thus making it unfit for edible
This is basically known as Vegetable Oil Refinery Plant.
The batch refining process consists of following section
- Neutralizing Section
- Bleaching Plant
- Deodorizing Section.
Continuous Edible Oil Refinery Plant
First stage of refining is to remove
Free Fatty Acids (F.F.A.) with caustic soda treatment called
Neutralizing Process, thereafter further processed in the bleaching
section under vacuum & treated with bleaching earth & activated
carbon for removing colour. Finally it will be deodorized under high
vacuum and high temperature to remove the odour from the oil.
The edible oil obtained in a batch refining 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 De- Waxing after
The refining of FATS and OILS is comprised of Degumming, Alkali
refining and Water Wash. There are few choices to choose, short / long
mixed process with Degumming or GUM Conditioning.
FATS and OILS containing gums and FFA (Free Fatty Acid) are required to
be removed by refining process for producing quality refined oil.
GOYUM provides a perfect process using Centrifuges from the best
The Oil received from previous stages contains traces of soap, iron and few ppm of Phospholipids and Carotenes. These contents are undesirable and required to be removed in Bleaching Operation, GOYUM's Steam Agitated Bleacher comprises an acid treatment, a separate Oil and Earth Mixing Device with Mechanical Mixer (this arrangement ensures no carryover of bleaching earth into vacuum system), main bleaching vessel and Hermetic Filters.
Dewaxing and Winterisation (Fractionation)
A very simple requirement of this

If your feedstock stems from palm oil or animal fats, there is a direct
natural way to modify it to ensure that it acquires greater value. By
separating the feedstock into liquid solid fractions, or by combining
different fractions, you can create the products that can match your's
customers exact specifications.
Fraction consists of gently cooling oils or fats in an accurately
controlled process, making it possible to crystalize the hard fat
In dry fractionation, the fat is kept at a temperature at which it is
in a partially liquid from. The crystals are then separated from the
liquid fraction by membrane filtration. The result is two distinct
products with different physical properties and melting points.
This can be achieved with absolutely no chemical modification, making
this the "natural" way to produce hard fats.
Physical Refining process is used to
remove FFA (Free Fatty Acid), using Steam Distillation method at high
temperature and under high vacuum and it is followed by Deodorisation
and an extra technical facility is added before deodorisation for
removal of free fatty acid.
Deodorisation process is used to remove unacceptable odour by Steam
Distillation, the Odoriferous Compound are strip off with the help of
live injected steam into heated oil under high vacuum.
GOYUM Deodorising tower has
- Maximum heat recovery
- Zero Percentage Contamination
- No Trans-Isomer generation
- Quick & Maximum flexibilities in feed material
- Large surface area exposure to vacuum
- Minimum carryover of oil with fatty acids
- Low Steam Consumption
- Suitable temperature for addition of anti-oxidant
- No packing / filling material inside
- No Short circuit of oil in process
- Practically no maintenance
Strategically design, combination of tower and fatty acid scrubber,
ensure practically no carryover of fatty acids into vacuum system.

Low Operating Cost Fractionation Plant which gives high Olein / soft
stearin yields at established control i.e. PLC (automation) for
efficient working and reliability of the plant.
The separation of Stearin and Olein is continuously done on Rotary
Vacuum Drum Filter and its principle is simple, whereas Crystallization
process involves a perfect technique to develop and grow the particles
size for easy smooth separation of Stearin and Olein.
Our technique ensures you a Perfect Technology.
