After oil pressing process or oil extraction process, we get crude oil. However, the crude oil can’t eat and sell to the market. The crude oil must be processed with Vegetable Oil Refining Equipment.
Vegetable Oil Refinery Plant can remove the components of edible crude oil which may have negative effects on taste, stability, appearance or nutritional value. To the extent possible, processing should preserve tocopherols and prevent chemical changes in the triacyglycerols.
Crude oil obtained from Oil Expeller or oil solvent extraction machine 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 vegetable purpose.
The vegetable oil refinery process consists of following section
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 vegetable 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 bleaching process.
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.
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 of 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.
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.
Vegetable Oil Refinery Plant Refining Process Flow Chart:
Vegetable Oil Refinery Plant designed by Wintone Machinery has the follow features:
Our vegetable oil refinery plant makes the oil pure, edible, more palatable and stable against rancidity upon storage. Our neutralizers are equipped with coils provided for efficient heating of the oil along with stirrers inside it. The bleaching section consists of high quality vacuum bleacher which removes all the impurities. And the continuous type well designed tray type multi-stage deodorizer vessel is robustly constructed to give the excellent refining results.
We have installed and exported vegetable oil refinery plants all across the world in different countries. Understanding that vegetable oil refining is a delicate task, we design excellent oil refining equipments and plants as per high end technology and latest market research. We can provide vegetable oil refinery plant on turn-key basis. We offer a batch type vegetable oil refinery plant upto 30 TPD capacity and we offer continuous type vegetable oil refinery plant upto 500 TPD capacity. Our oil refinery plant finds an extensive application for almost all types of oil seeds.
