Soybean Oil Refining Machine main section in the soybean oil refining process: from degumming acid to decolorization, deodorization and dewaxing.
Soybean Oil Refining Main Section and soybean oil refining process introduction:
Degumming
This progress adopts hydration by adding into hot water to remove the agglomerated and deposited hydrosol and phosphatide because of their water affinity. The separated gum (after being dried) can be made into lecithin or added into cakes or meals in the extraction workshop. Hydration degumming process can improve oil edibility, storage and do well to downstream neutralization section.
Neutralizing
Oil containing fatty acid is mixed mechanically with a slight excess of alkali to react with fatty acids present to form soaps. The mixture is centrifuged to separate oil from soap stock. After washing with water, the water is separated from the oil in a second centrifuge.
Bleaching
Degummed and neutralized oil are pumped into this system and mixed with by the use of bleaching earth, a special soap, gum, and pigment attracting adsorbent. The mixture enters the Pre-filtration Dryer where the moisture in the oil and adsorbent is evaporated. Then the oil is pumped through an automatic closed filter to remove clay.
Deodorization
The oil contains the disagreeable flavor and odors that are naturally present or created during processing. All odoriferous matter is distilled off by injecting high pressure steam through vacuum system. Then the product achieves the national standard.
Main Equipment
Refining Pot: remove the gum, phosphoric acid etc. (2 sets)
Decolorizing Pot: remove the color from neutralized oil (1 set)
Deodorizing Pot: remove the solvent, smell, water from decolorized oil (1 set)
Steam Generator: produce steam for the workshop (1 set)
Heat Conduction Furnace: offer enough heat for the refining sections (1 set)
Other Auxiliary Equipments: Air compressor, pumps, filters, etc.
We can provide cooking oil...
