Introduction of main equipment:
1.Degumming, water washing,alkali refining and drying
Crude oil through the filter into the refining pot,added at a concentration of 85% phosphoric acid when oil rose to a certain temperature,after thorough mixing, so thoroughly transformed into a hydrophilic phospholipid lecithin, dissolved at the same time a large number of complex production process high acid value oil iron ions, then still natural precipitation. Cassia Cassia pumped into the lower part of the release of the pot, heated saponins residual oil separation. Pump water into the upper portion of the pot, with the addition of 10% warm water, after well mixed, and then precipitated static nature, oil and water layers were separated. Soap water into the lower part of the oil-water separator, the upper part of the pump to the dryer off moisture in oil, the oil after dehydration into dewaxing section.
2.Dewaxing
Drying oil and dewaxing refined oil to process hot exchange,into the precooling storage,send to crystallizing tank,to adopt the frequency adjust speed,to low the temperature slowly,then separate out wax to form crystal.Through pump go into the filter to press,decease oil connect in the wax.
3.Decolorization
Remove the pigment and residual gum,to avoid producing return oil state when high temperature physical deacidification.
4.Physical deacidification, deodorization
In order to remove the free fatty acid and small molecule volatile.Selection of efficient high acid value packed tower flashed rice bran oil deacidification, plate tower with a combination of low acid value to delay rice bran oil deacidification, deodorization, thermal bleaching, advanced technology and reliable for different grades of oil refining
5. Degreasing
Deodorized oil with defatted oil into the pre-cooling heat exchange tank, followed by crystallization feed tank. Crystal frequency control tank, slowly and evenly cooling, the precipitated lipids
