Sunflower oil refining description
After the crude oil is preheated, add light alkali to make the gum and some free fatty acids in the oil from soapstock, and then separate the soapstock, then add hot salt water to the oil to wash, and separate the soap water. Degumming is completed by the same washing once or twice. The degummed oil enters the decolorization process, adds activated clay to decolorize in the decolorization tower, and then is pumped into the leaf filter for filtration. After polishing, the filtrate enters the next process. After the leaf filter is blown dry, the waste clay is discharged through vibration. The decolorized oil is pumped into the gas separator for vacuum deoxygenation, and then the oil is pumped into the oil heat exchanger and deodorized oil for heat exchange preheating, and then it enters the heater and enters the combined deacidification and deodorization tower when it is heated to about 250 ℃. Deacidification and deodorization are carried out in the state to maximize the removal of fatty acids, odors and other volatile substances in the oil. The fatty acid mixed steam is discharged from the top of the tower into the fatty acid trapping system and sold. The oil is drawn from the bottom and pumped into the heat exchanger to exchange heat with the oil to be deodorized, and then cooled to obtain the deodorized oil. The deodorized oil is cooled and crystallized in a crystallization tank and then transferred to the crystallization stage. The oil after crystallization and crystallization is pumped into a filter to separate wax and grease to obtain refined oil.
