Rice bran oil refining machine
    Rice bran oil refining machine
    Main equipment of rice bran oil refining machine:
    Mixer, centrifuge, heat exchanger, gas separator, heater, decolorizing tower, vibration filter, combined deodorization tower, fatty acid catcher, cooler, four-stage steam jet pump, heat conduction oil furnace, etc. The combination of rice bran oil refining machine is also suitable for the following varieties: rice bran oil, tea seed oil, corn germ, animal oil and other high acid value, more impurities oil.
    The main features of the rice bran oil refining machine are as follows: the physical refining process is adopted without deacidification by alkali refining, which avoids the loss of neutral oil and greatly reduces the production cost. The dewaxing process is arranged before decolorization by the rice bran oil refining equipment manufacturer. Due to the high content of fatty acids in the oil, the high melting point of fatty acids and the decrease of temperature, some fatty acids take the lead in solidifying, which leads to the sharp rise of viscosity of the oil. For the furfural oil with an acid value of 30 (KOH) / (mg / g), the temperature drops to 20. C has become very viscous, which makes dewaxing and filtration difficult. Therefore, the filtration temperature should not be lower than 20. C.
    The dewaxing process of the rice bran oil refining machine is as follows: the vacuum dehydrated bran oil is put into the crystallizing tank and cooled under slow stirring, so that the oil temperature is about 24 hours, from 70. C slowly and evenly down to 25. C. continue to mix slowly and keep the oil temperature unchanged, and carry out crystal nourishing for more than 48h. After crystal nourishing, use the blade filter to precoat the silicon bath soil for filtration. The oil quality should be kept at 25 during filtration. C remains unchanged. The increase of filter temperature can speed up the filtration efficiency and reduce the oil content of wax paste, but the wax content in the dewaxed oil will increase, the cloud point will increase, and the transparency will become worse; the decrease of filter temperature can reduce the wax content in the oil, reduce the cloud point, and improve the transparency, but it will significantly reduce the filtration oil rate and increase the oil content of wax paste. In practice, the dewaxing temperature of rice bran oil with acid value of 20-30 (KOH) / (mg / g) is controlled at 20-25. C. good comprehensive effect
