CONTINUOUS VEGETABLE OIL REFINERY PLANT

Basic process of refining is same in both batch & continuous refinery. Only difference is instead of a measured batch, crude oil is processed continuously with constant stream of flow. In between required utilities & chemicals are added continuously in measured quantity. Crude oil from obtained from expellers, 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 edible
purpose. Basic stages of the process are as below:

• Nutralizing

• Bleaching

• Dewaxing & Deodorizing.

DEGUMMING AND NEUTRALIZATION SECTION:-

• The crude oil is pumped to Neutraliser from oil mill 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 SECTION:- 

• 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
