Takeffax is an important part of improving the quality of edible oil.

The existence of waxy mainly affects the palatability of oil and fat, so the main purpose of dewaxing is to improve the palatability of oil and fat, and improve the sensitivity of fats such as transparency and brightness.Different oil products have different waxy content. For the following oil products (such as: corn oil, rice bran oil, sunflower seed oil, cottonseed oil, etc.) are almost necessary.
Under a certain temperature, the melting point differences and solubility of various glycuts and fats that make up the grease of grease are divided into two parts: solid and liquid.

Sunflower Seed Oil

Waxing ingredients oil: sunflower seed oil, corn oil, rice bran oil, cottonseed oil, etc. Commonly provided raw oil: Palm oil, palm oil, palm kernel oil, hydrogenated soybean oil and special oils such as Sharow Shuang resin, butter resin, mango resin, etc. Animal oil: milk fat, cod fat, lard oil, fish oil, etc. 1.Brief map of process flow cooling → crystallization → crystal → filter → dewaxing oil Craft description 2.1 Before the wax is dewaxed, it is generally stored in large cans. The oil temperature basically does not exceed 10 ° C, so some waxes have been made in oil.If the crystals and crystals are directly performed, it will affect the precipitation and crystallization of the entire process of wax, so the oil of the waxed wax must be heated at the beginning to dissolve the wax in the oil.In order to ensure the increase in the collision between the precipitated wax molecules, and at the same time, the waxy oil is cooled evenly, and it is necessary to stir properly.But the speed should not be too fast, otherwise it will break the crystallized particles, which is not conducive to crystallization. 2.4 Smooth oil continuously cools down and crystals to a certain temperature, stop stirring, keep it for a long time, so that the undeorned waxy texture will continue to crystallize, so that the small grains will continue to grow, which will be kept crystal.In the process of crystallizing crystal, with the precipitation of most waxes, and at the same time, it is accompanied by more solid -lipid precipitation. Generally, the analysis of the output accounts for 1 to 2%of the oil.This process fully considers this feature, and the two -unloaded winter filter with a large area is selected. When a filter is filtered, a wax removal is maintained to keep the production continuity. The filtered oil pump into the plate into the plate heat exchanger with the heat exchanges without dewaxing oil.
