What is leaching oil?

September 24, 2021

The leaching oil refers to the edible oil made by the leaching process. Most of the leaching oil is colorless and tasteless, and various nutrients and material composition meet the national standards, so you can eat it with confidence.

The production process of leaching oil mainly includes two parts: leaching and refining. Soak or rinse the pretreated oil or pressed cake with a solvent (namely No. 6 light gasoline) to dissolve the oil in the solvent, and filter to obtain a mixed oil containing solvent and oil. After the mixed oil is evaporated and stripped, crude oil is obtained. The crude oil contains various trace impurities and cannot be eaten directly. The impurities in the crude oil must be removed by refining. Refining generally includes four parts: degumming, deacidification, decolorization and deodorization. After refining, the crude oil becomes edible oil that meets national standards and can be sold on the market. According to the characteristics of the oil and the market demand, the edible oil can be further processed to obtain high-quality edible oil.

The production process of leaching oil has a high degree of automation and low labor costs. After leaching, the residual oil ratio in the cake is less than 1%, and the loss of edible oil is small. In addition, the quality of the cake can also be controlled through the process to obtain additional economic benefits. Oils with low oil content are generally processed into leaching oil by leaching, such as rice bran, soybeans and so on. The leaching method can reduce oil loss and ensure production efficiency. If you have an edible oil production plant with an output of more than 20 tons/day, Henan Zhongxing’s engineers suggest choosing the leaching method to produce edible oil, which has high oil output efficiency and will also increase economic profits.
