There are two methods in rice bran oil manufacturing process. One is rice bran oil press process, and another is expansion leaching process for rice bran oil production.
But because of the low oil content, expansion leaching process is most popular in rice bran oil manufacturing process. This article mainly explain the effect of puffing machine in rice bran oil manufacturing process.
Oil content of rice bran is 14%-24%, it is a low oil content oilseeds. Compared with other oilseeds, rice bran has the following characteristics:
1. High starch content, variety of enzymes, easy to rancidity;
2. Containing lecithin, bran wax and other colloidal substance;
3. Small density, fine grain, high powder, many varieties.
Rice bran puffing machine can make the rice bran powder become columnar structure of porous with good permeability, and can increase the density of rice bran, improve the seepage velocity of solvent, reduce residual oil of cake.
After puffing, the refreshing time of rice bran is extended, the acid value of rice bran is greatly reduced, and the quality of crude oil is also effectively improve.
