Vegetable Oil Refining Plant

Mectech is one of the leading manufacturers, Supplier & Exporter of Turnkey project plant & machinery of vegetable oil refinery. Vegetable oil refining can be done through physical & chemical process which, Mectech offers as per the customer’s requirement.

The inherent harmful factors for human consumption like free fatty acids (FFA), gums, sediments, odoriferous and colouring materials present in crude oils are removed completely to make the oil edible. MECTECH takes special care in all the stages and after undergoing the process of neutralisation, bleaching and deodorisation, the oil is safe and fit for human intake.

Degumming / Neutralization

Degumming is a process of removing phospholipids to improve its physical stability and facilitate further refining. Presence of phospholipids leads the oil colour rise in high temperature and they can also serve as precursors of oil off -flavor. Free fatty acids, pigments and other impurities are also partially removed by degumming. Mectech follows different types of degumming processes. These processes are (ie water degumming acid degumming Exzymatic degumming) being selected based on methods of processing, chemicals used and the content of phosphatides in the crude vegetable oil.

Continuous Bleaching

“Bleaching” is a process of selective removal of pigments and impurities by the physical and chemical interaction of an adsorbent with an oil or fat to improve its quality.

This process refers to the art of removing : Color pigments, Dirt, Trace metals, Removal of polycyclic Aromatic compounds & Phospholipids.

Salient features:

  • MECTECH's unique design of bleacher requires no mechanical agitation and bleaching is carried out under optimum conditions of moisture content to achieve perfect results. This gives saving in Bleaching clay & power consumption.
  • Mechanically agitated bleacher has a tendency to affect the quality of oil due to leakages from gland system. It also involves maintenance as well as wear and tear cost. Mectech bleacher being without mechanical agitation is maintenance free.
  • Mectech unique design of bleacher keeps bleaching earth under suspension thereby avoiding dead areas. This results in lower consumption of bleaching earth.
  • Since the bleaching process is carried out under controlled parameters, better and consistent quality of resultant oil is guaranteed.

Deodorization

Deodorization is a vacuum stripping process in which a given amount of a stripping agent (usually steam) is passed for a given period of time through hot oil at a low pressure. Hence, it is mainly a physical process in which various volatile components are removed.

Salient features:

  • Most efficiently designed oil to oil heat exchanger fitted in last tray of Deodorizer ensures minimum heat energy requirement.
  • Elaborate and efficient design of fatty acid scrubbing recovery system ensures virtually no carry over fatty acid into barometric condenser.
  • Most efficiently designed heating coil which prevents to charring of oil during the process.
