1.Screening:Removing the chaff and broken rice in the rice bran, in case of they will influence the oil yield and the desolvent of wet meal in the next process. In the process of puffing section, the general requirement of impurity is less than 3%, and the requirement of crude fiber is about 8%.
2.Magnetic separation :Clearing the iron impurity which migLD be in the rice brain. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect. As the rice brain particles are small and poor liquidity, the iron impurities are always be wiped off by the magnetic barrels installed in the feeding port.
3.Quenching and tempering :it is the process of preheating so that to improve the temperature of the rice bran before puffing. After quenching and tempering the temperature will be controlled at 65--75 °C, and the moisture will be controlled at 10 ~12%. Thus, on the one side, it can increase the output of the extrusion machine, and on the other side, it can improve the quality of the puffed rice bran.
4.Puffing: the rice bran is injecting high pressure steam and high temperature water through the extrusion machine, so that it can improve the temperature and moisture in the extrusion machine,and can also form the high pressure to process the rice bran. All these can make the the rice bran become porous columnar structure from the original pulverized state.All these effectively passivate the activity of various of enzyme in the rice bran, and destroy the fat layer structure, so that it will be easier for the oil yield.
5.Drying:The moisture of puffed material comes from the extrusion machine is too big and the temperature is too high for direct leaching, the must be experience to process of drying and coo-ling, thus the moisture will reach 7%--9%, and temperature will reach 50-55°C. After puffing, the rice brain are usually dried and cooled by plat dryer.

Description of oil refining plant about 2016 newest paml oil refinery processing equipment,palm oil refining machine production line,paml oil refinery plant equipment
1.Edible / Vegetable oil refining is a step by step process. Refining of oil removes phospholipids, pigments, off-flavor, free fatty acids, and other impurities. The entire oil refining plant process comprises Degumming / Neutralization, Bleaching, Deoderization, and Winterization(Optional).
2.This system is batch type refining, itÃ¢ÂÂs the concentration of the big scale oil refining line, the capacity could be 1~10Ton per day.It could refine more than one kind of crude oil , such as salad oil, high cooking oil, first grade oil and second grade oil, also it could refine animal oil, such as the lard oil, fish oil. it's the idea choice of Medium and small scale oil mill plant.

(1)pump crude oil into refining tank and heat with conduction oil, and the temperature will reach about 70ÃÂ°C-80ÃÂ°C after one hour.
Add acid or alkali to separate according to the acid value. After one hour's processing and 4-6hours deposit, then convey soap stock to storage tank.
(2)Pump refined oil into decoloring tank. When it is up to 90-110ÃÂ°C after one hour's heating, add clay into tank for 20min's processing. Then separate clay and oil with filter.
(3)Put discolored oil into deodorization tank with vacuum pump. Heat and process with steam for odor removal. After filtering, you will get final oil product.
Functions of oil refining plant main parts about 2016 newest paml oil refinery processing equipment,palm oil refining machine production line,paml oil refinery plant equipment
(1) Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.
(2) Decoloring section: used to remove off pigments, bleaching oils and grease dehydrate.
(3) Deodorizing section: to remove off the odor components in oil.
(4) Dewax: used to remove off the wax in the oil, in order to get the high quality oil.
(5) Heat-transfer oil stove: supply each device production needing heat enerLD, temperature reach above 280ÃÂ°C.
(6) Steam generator: produce the needing steam for de-odoring and distillation.
(7) Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.
(8) Press filter: filter clay, filter out clear oil.
(9) Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.
