Product Description
The introduction of rice bran oil processing machine:
Rice bran oil processing machine includes three important parts: oil material pretreatment process, oil solvent extracting process and oil refining process.
1. Rice bran pretreatment of rice bran oil processing machine:
The section mainly use cleaning machines, cooking machine, puffing machine and drying machine.
2. Solvent extraction section of rice bran oil processing machine
Oil extraction is an advanced oil production craft, now widely applied to oil plants,and it's an organic solvent extraction method,oil is extracted from rice bran by contact(soaking or spraying) of solvent and rice bran.
Rice bran oil extraction process:
A. Desolventizing-toasting section
The meal from extractor contains 25-35% solvent, for recovering solvent and getting better meal, solvent can be toasted by heating.High material layer toaster is usually applied to remove solvent from meal as well as dry extracted meal; DTDC desolventizer should be used for extracted rice bran meal.
B. Evaporation and steam-stripping section
The mixed oil will pass through two evaporators to make solvent inside transform into gas , and solvent will be recovered through condensers and reused. These two evaporators are not with same size , the first evaporator is bigger than the second one because there are more solvent inside mixed oil in the beginning . After evaporating, the oil will be pump into the stripping tower. Finally, we will get crude rice bran oil ready for oil refining.
Purpose of rice bran oil processing machine:
(1) Adopting negative pressure evaporation can ensure excellent oil quality;
(2) Extraction system is highly adaptable,and can adapt to different oilseeds;
(3) Unique exhaust gas absorption systems ensure good absorption effect;
(4) Energy saving design utilize heat energy for many times and saves steam consumption.
The advantages of rice bran oil processing machine:
(1) high oil yield, low residual oil rate of meal;
(2) low labor intensity;
(3) good working environment;
(4) good meal quality.
3. Refining section of rice bran oil processing machine:
Rice bran oil refining process:
Crude rice bran oil→degumming section→deacidification section→Decolorization section→Deodorization section → Dewaxing & defatting section
A.Crude oil degumming section
Hydrated degumming, mainly is to remove phosphatide inside crude sunflower oil in order to reduce oil loss and improve quality of oil.
B.Alkali refining deacidification section
Alkali refining, using alkali to neutralize free fatty acid with by-product of soapstock, which is used for making soap.
C.Decolorization section
Decoloration using bleaching clay to absorb darker colorant inside crude oil.
D.Deodorization section
Deodorization is using high temperature to remove the impurities with bad smell .
E.Dewaxing & defatting section
Dewaxing is using low temperature to freeze wax inside refined oil and then separate wax with vibrating screen.
