The oil content of rice bran is low, so the rice bran oil is usually extracted by extraction process. The development of rice bran oil extraction machine in my country has been very mature. From raw material pretreatment to refined finished oil, a full set of equipment can be purchased in one stop. Rice bran oil is soaked in solvent in the extraction equipment to extract oil, and then the solvent is evaporated, desolventized, condensed and recycled by different melting points to obtain rice bran oil extraction crude oil.
The refining of rice bran oil can be divided into chemical refining and physical refining. Chemical refining is a process that is widely used in oil mills, but chemically refined rice bran oil uses the principle of acid-base neutralization to deacidify, and the deacidification is relatively sufficient. The oryzanol and other physiologically active substances in rice bran oil are less retained, the neutral oil loss is large, and there is a lot of wastewater, which is easy to cause environmental pollution. Therefore, Huatai refined oil equipment manufacturers usually choose physical refining process to refine rice bran oil.
The physical refining process is a process of deacidification by high-temperature distillation process, in which free fatty acids and low-molecular odor substances in the oil with much lower volatility than triglycerides are discharged along with steam. It can also be called “stripping deacidification” or “distillation deacidification” method. The physical refining method has low neutral oil consumption and high oil yield. It reduces the use of alkali solution in production, significantly reduces wastewater and refining consumption in production, and is more economical and environmentally friendly. The loss of oryzanol in oil is small, but the physical refining process has strict requirements on the pretreatment of raw oil, generally requiring the phosphorus content to be below 15mg/kg.
In addition to process factors, the quality of rice bran oil refining machine should also be considered when refining rice bran oil. The combination of good quality refining equipment and process can create higher benefits for the oil mill, and the quality of refining equipment also determines the quality of oil, which can directly affect the output value and income of the oil mill. The purchase of refining equipment should also be investigated from many aspects such as quality, price, brand, service, and manufacturer. If you want to buy refined oil equipment, you can visit Huatai Cereals and Oil Machinery Co., Ltd.
