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.

1. Refining Process about Professional refinery equipment for cooking oil,Cooking oil refining equipment,Cooking oil refining project machine
2. Main refining process introduction about Professional refinery equipment for cooking oil,Cooking oil refining equipment,Cooking oil refining project machine
(1).P-acid degumming operation:
Drawing the filtered or settled crude oil into the neutral pot, control oil te-
mperature 40 ÃÂ° C, liquid level cover the neutral pot volume about 80 %.Add
into the neutral pot P-acid with 85% concentration, 0.1-0.2% oil weigLD.Start
up neutral pot, make main shalf stirring at 60-70 r/min, finish de-gumming
in 30 min.
(2).Alkali de-acid operation:
After finish de-gumming process, at once add into lye carrying alkali refini-ng de-acid, lye concentration 16 ÃÂ° Be super alkali is 0.1-0.3% oil weigLD, after finish adding, continuous stirring 30min, when soap particles accumulated
condensing, should reduce stirring speed, 30r/min avoid emulsion. After adding alkali, gradually rising temp to the
end temp 65 ÃÂ° C, see to that the rising temp speed should control at 1 degree per minute, not too fast. Shut off neutral pot drive part, the oil settled in the pot 6-8 hours, make oil separate from soap.
(3).Water rinse operation:
Adjust the neutral pot oil temp to about 85 ÃÂ° C, add into hot water whose te-mp higher oil temp 10-15ÃÂ° C, the water use
amount each time is 10-15% oil weigLD.
Start neutral pot drive part, make the main shalf stirring washing at 30r/min, make the oil and water fully contact, stirring
time 5-10 min.If oil/soap separate not ideal, the oil contains relative high left soap, the fir-st time washing,
better to use thin salt water evenly spray into oil.
After dehydrate, inhale 3-5% oil weigLD active clay into the de-color pot to carry absorb de-coloring.
Decolor pot main axis stirring speed 60r/min, time 20 min, vacuum degree 750mmHg, is the whole absorb de-color craft process requirement.
Shut off vacuum valve, open vacuum break valve, stirring non-stop, reduce the oil temp down to 70 ÃÂ° C, the de-color finished.
Continuous stirring, open oil outlet valve, press the de-color oil into the press filter,filter away waste clay,
the last use air compressor blow clean and dry
Open the vacuum valve, make the pot inside vacuum degree gradually reach above 750mmHg.Inhale the de-color oil after
filter into the de-odor pot, see to that oil amount should cover the pot volume 60% Control oil temp at 240 ÃÂ° C - 260 ÃÂ° C
use the direct steam under 0.1 -0.3Mpa to distillate 3-4 hours.Shut off steam, shut off heat source, when the oil
temp cooling to below 80 ÃÂ° C, shut off vacuum, release de-odor oil , the de-odor process has finished.
3. Characteristics about Professional refinery equipment for cooking oil,Cooking oil refining equipment,Cooking oil refining project machine
This units belongs to intermittent refining oil equipment, has all functions of large, small scale intermittent refining
equipment, and better than them. This equipment can produce high-cooking oil or salad oil. This units complete set
combined, self-prepare heat source, gas source, elect-rics control. LigLD weigLD, save electricity , convenient use,
this machine do not need special basis, either indoor or outdoor is OK, just need to make up power source, water,
prepare coal, alkali, Pacid, active clay, edible salt and other consume materials.
