Many people feel very strange about oil refining equipment. Our edible oil is obtained in two ways. One is the chemical leaching method, which uses chemical solvents to soak oil crops so that the oil in the oil crops is completely leached out, and then it can be marketed after being refined and desolventized. Sales. There is also a physical pressing method, which uses an oil press to squeeze most of the fat in the oil crops, and then enter the market after refining. These two processes, no matter which one is used, must be processed by oil refining equipment before they can meet national standards before they are allowed to be marketed. The edible oil that we usually come into contact with more often is the edible oil that has been simply filtered after being pressed by the oil press in the rural oil mills. This can only be called "crude oil." The national supervision of processing and trading in the private sector is not too strict, but it does not meet the food standards required by the country.
There are three types of impurities in crude edible oil-solid impurities (that is, oil residue), suspended impurities (phospholipids, acidic substances, moisture, etc.), and pigments (some crude oils are black and red in color). The role of oil refining equipment is to remove these impurities through physical methods to meet national requirements. Oil refining equipment adopts physical refining process. The whole process requires degumming (phospholipid), dehydration (drying, extending shelf life), deacidification (reducing peroxide value), decolorization, and deodorization. Some types of edible oil also need dewaxing and so on. Only after these treatments can the standards required by the country be met. The entire refining process takes 8-12 hours (different oil types and refining grades require different time). Then the difference between the refinery equipment produced by different manufacturers is that the material is different, the process is different, the refining consumption (loss during the refining process) is different, the quality is different, and the advanced level of the equipment is also different, which leads to The price of refined oil equipment is different. Now that the state’s laws and regulations on private oil mills have been promulgated, small private oil mills
