Choosing the suitable rice bran oil processing machine depends on several factors, such as your budget, production capacity, raw material quality, and desired oil quality. Here are some general guidelines to help you make a decision:
If you have a large budget and want to produce high-quality rice bran oil with high oil yield, you can choose the solvent extraction method. This method uses edible-grade solvents to extract oil from rice bran, which is a by-product of the rice milling process. The solvent extraction method is recognized as the most advanced vegetable oil production technology internationally. However, the investment cost is relatively higher and the capacity is larger, usually 100 tons per day and above. You will need rice bran oil solvent extraction equipment, such as rice bran extruder, rice bran oil solvent extraction machine, and rice bran oil refining equipment.
If you have a limited budget and want to produce rice bran oil with moderate quality and oil yield, you can choose the physical pressing method. This method uses mechanical pressure to extract crude oil from rice bran. It is more flexible for the production capacity, from small scale to large scale, and its equipment requires less investment cost. You will need rice bran oil pressing equipment, such as rice bran oil press machine, rice bran oil filter machine, and rice bran oil refining equipment.
No matter which method you choose, you will need to pretreat the rice bran before extracting oil. The pretreatment process includes cleaning, drying, conditioning, expanding, and cooling. The purpose of pretreatment is to improve the quality and efficiency of oil extraction.
After extracting crude oil from rice bran, you will need to refine it to remove the impurities, such as gums, pigments, free fatty acids, odors, and wax. The refining process includes degumming, deacidification, decolorization, deodorization, and dewaxing. The refined rice bran oil has a mild nutty flavor and a high smoke point. It is suitable for cooking and frying.
