Physical Refining Plant Manufacturer & Supplier

This is employed mainly for high FFA oils like Palm Oil and Rice Bran Oil. Physical refining is carried out in two steps i.e.

  • Pre-treatment & Bleaching
  • Deacidification/Deodorization

Pre-treatment & Bleaching

The aim of Pre-treatment & Bleaching is to remove minor constituents namely phospodites, heavy metals and other oxidative components prior to Deacidification/ Deodorization.

Specially designed Pre-treatment & Bleaching by MECTECH is cost effective and ensures perfect results.Equipments designed by MECTECH ensures deacidification by distillation of free fatty acids combined with partial or complete deodorization.

Deacitification / Deodorization

Salient features:

  • The Deaeration and Pre-heating is gradual and methodical so that all the oil comes in contact with this sparging system at the free surface exposed to vacuum.
  • An additional top heating tray is provided in the Deacidifier/Deodorizer to compensate the unavoidable oil cooling of about 8'C due to evaporation of fatty acids.
  • Perfect deodorization is accomplished by providing large free surfacing area contact between oil and stripping steam at an absolute pressure of 2 m bar. This results in furnishing oil surface layer of numerous bubbles having 5-10 mm diameter.
  • These small bubbles burst and they discharge the water vapour saturated with distilled fatty acids and the odoriferous compounds. These ascending vapours are immediately and freely taken out into lateral ducts through large section opening provided in top of each stripping tray.
  • This ensures virtually no pressure drop from top to the bottom tray. Most efficiently designed oil to oil heat exchanger fitted in the last tray of Deodorizer ensures minimum heat energy requirement. Elaborate and efficient design of fatty acid scrabbling recovery system ensures virtually no carry over of fatty acids into barometric condenser water.
