Oil is a mixture of various triglycerides. At a certain temperature, the process of separating oil into different triglyceride components is fractionation. The extraction equipment can be used to process vegetable oils such as palm oil, palm kernel oil, cottonseed oil and animal oils such as fish oil, butter and lard, thus greatly improving the added value of oil products.
    
According to the characteristics of cooling crystallization and separation process, dry fractionation is an economical and effective method, which means that oil in the dissolved state is slowly cooled to a certain extent without adding any solvent, and then filtered to separate crystallization and precipitate solid esters.
