With rich experience and advanced rice bran oil mill machinery technology in this field, KMEC is your reliable rice bran oil machinery manufacturer and supplier. The output rate of rice bran oil mill machinery is between 8-11% and the capacity is from 5t to 100t per day.
In order to obtain high quality refined rice bran oil, the refining process begins by reducing excess free fatty acid and then decreasing the color with activated clay. After decreasing color, the oil is forwarded to the crystallization process before filtering the wax through a filter press machine. The next process is to remove the odor by using high-pressure steam deodorizer at a temperature of 230-240 degrees Celsius. The heating medium used in this process is high pressure steam. No thermal oil or PCB (Polychlorinated Biphenyl) involved in the rice bran production process at all. The result is a high quality and safe rice bran oil.
Rice Bran Oil Machinery
There are three sections in rice bran oil production process. They are oil pressing section, solvent extraction section, and oil refining section.
1. Oil Pressing Section
Rice bran should be drying and frying for fresh rice bran , storeage time is less than 3 days before pressing or the quaility will be reduced and effect the final oil quality. The oil pressing plant is composed of cleaning process, drying units, pressing unit, conveyor, electrical cabinet box,etc. It's complete set of oil pressing equipment, which is automatically operated to save more labor and cost.
2. Solvent Extraction Section
This process is for more than 50t oil mills. Certainly if the capacity is less than 50 tons, or it is high rate of output oil , this process could be saved . The second way to extract oil for using chemical solvent to dissolve oil content contained in cake or direct oil seeds, only for lower oil seeds, for example soybean. Then oil is separated from solvent by vaporizing solvent out. In configuring the solvent extraction plant, pre-pressing may be involved in which case seeds are lightly pressed, and which leaves about 14% to 18% oil in the pressed cake. Solvent extraction will further process these cakes and leave less than 1% oil in the final cake. This method results in higher yields, more oil; lower power consumption, lower wear & tear / maintenance and high extract efficiency. Thus it could be used as complementary equipment to extract the oil remained in cake, which yields are extra profits.
3. Oil Refining Section
The crude vegetable oil from above mentioned two ways of extracting,
oil pressing and
solvent extraction will be pumped into oil refinery units to produce rice bran oil at various grades.
The main equipment of rice bran oil refinery is various kinds of vessels and tanks carrying on different tasks. These tasks may include filtering, neutralization, degumming, decolorization, deodorization, dewax, etc. Different combination of steps and the treating degree of each step result in different grade rice bran oil.
