In the rice bran oil production process, the crude rice bran oil extracted by the rice bran oil extraction machine contains some impurities and residual extraction solvents, so it is necessary to use rice bran oil refining machine to remove impurities and harmful substances in the oil. In the rice bran oil processing, in addition to rice bran oil, a series of by-products such as rice bran meal and rice bran wax can also be obtained.
Rice bran wax is an ester formed by fatty acids and fatty alcohols in rice bran oil, and also includes some free fatty acids. These waxes exist in the oil and crystallize when cooled to a suitable temperature, making the oil turbid and affecting the quality and appearance of the oil. At the same time, the chemical properties of bran wax are relatively stable, generally not easy to hydrolyze, and not easy to be digested and absorbed by the human body. Therefore, rice bran oil dewaxing process needs to be added in the rice bran oil refining process. Rice bran wax has a high utilization value and is widely used in food processing, daily chemical processing, chemical production and other aspects.
1. Industrial use
Rice bran wax has a wide range of uses in industrial production. It can replace industrial products such as tantalum and palm wax and is used in the production of various industries. In addition, rice bran wax is an important raw material for extracting high-carbon fatty alcohols. It has a particularly high application value in industry.
2. Uses in the cosmetics industry
Rice bran wax is also a common raw material for the production of cosmetics. Various cosmetics made from it are relatively mild in nature and can be directly applied to the surface of human skin. Frequent use can make the skin delicate and slow down skin aging. In addition, cosmetics added with rice bran wax can also enhance human resistance to ultraviolet rays. Applying in summer can prevent the skin from being sunburned.
3. Fiber manufacturing
Fiber manufacturing is also an important use of rice bran wax. After adding it, it can improve the flexibility, smoothness and glossiness of fiber products, allowing people to produce high-quality fiber products. In addition to these uses, rice bran wax can also be used as a stabilizer or lubricant, and can also be used as an excellent heat-resistant thickener in grease.
As an extension of the rice industry chain, rice bran oil processing can greatly improve the utilization rate of rice. In addition to the main product rice bran oil, rice bran meal can also be obtained during the extraction process of rice bran oil, and rice bran wax can be obtained during the rice bran oil refining process. Lecithin, oryzanol, etc. can also be extracted from rice bran oil soap stock and can be used in industries such as medicine. These by-products have also brought considerable economic benefits to enterprises.
