Edible Oil Refining Line:
Refining Process Flow and the Descriptions:
Degumming: Remove solubility impurity in the crude oil is degumming. Because phospholipid in a great part of solubility impurity in the crude oil.In industry, degumming also calls get rid of phospholipid. Before alkali refining, remove solubility impurity is a very useful way, it can reduce loss in the oil, increase oil quanlity, save alkali, and phospholipid can be got. Crude oil is pumped out from the Buffer Tank. Passing through dosing system, the oil enters into the Heat Exchanger to recover part of heat. Decolorer: The aim of decolor is improve the color of oil, and supply the eligible oil to deodorizer. So the standard of oil should be made according to the demand of oil.Through decolorer, we should get the most change in the color, at the same time, keeping the lowest loss. Deodorizing Section: Deodorizer not only remove the fetid impurity, increase oil smoke point, make better taste, but also improve oil stability, quanlity and chroma.At the same time,we can get rid of free fatty acid, peroxide, heat-sensitive coloring matter, protein in the mucid oil cake, polycyclic aromatic hydrocarbon, and residual pesticide residue. In the oil process, we always emphasized deodorizer. |
