The raw material of rice bran oil is rice bran, a byproduct of rice processing. Most of the trace nutrients in rice are lost in the process of rice processing as the rice bran falls off. Rice bran oil is extracted from fresh rice bran.
As a byproduct of processing, there are a large number of highly active enzymes in rice bran, which quickly decompose the fat in rice bran into free fatty acids and water, causing the rice bran to become rancid and deteriorate. If not processed in time, the quality of rice bran will deteriorate, the oil content will decrease, the acid value will increase, the color will become darker, and the oil yield and quality will be seriously affected. Therefore, fresh rice bran needs to be processed in time, otherwise preservation measures should be taken to inhibit enzyme activity and store the rice bran in a centralized manner for processing.
Common rice bran oil extraction processes include pressing and extraction. Rice bran has a low oil content and is prone to rancidity and deterioration. Although the rice bran oil processed by the pressing process is of good quality, for rice bran oil mills with large output, the use of rice bran oil extraction equipment to produce rice bran oil is a better choice.
Rice bran oil is usually extracted by puffing extraction process. After cleaning and screening, the rice bran is extruded, dried, and powdered by the rice bran extruder machine before entering the rice bran oil extraction equipment to extract the mixed oil. The solvent and oil have different melting points, and the solvent is recovered by evaporation, stripping, and condensation for repeated use to obtain the crude rice bran oil and enter the rice bran oil refining section.
The rice bran oil refining section uses a series of process treatments such as degumming, deacidification, decolorization, deodorization, and dewaxing on the crude rice bran oil by rice bran refining equipment. After removing the phospholipids, free fatty acids, pigments, gums, waxes, moisture, and odor substances in the crude rice bran oil, it is refined into edible high-grade edible rice bran oil, which can also be called rice oil.
The location of the rice bran oil processing plant can be selected close to the rice processing plant. This can save time, reduce the transportation time of rice bran, and timely extrude and preserve the rice bran to improve the quality of raw materials. On the other hand, it can also reduce the cost during the transportation of raw materials. The fresh rice bran obtained by the rice workshop is promptly sent to the rice bran oil processing workshop for pre-treatment and extrusion, and then the crude rice bran oil is extracted through the rice bran oil extraction machine, and then the edible rice bran oil is obtained after refining and removing impurities through the rice bran oil refining machine.
