There may be many ways to extract plant oil. Our common ones are low-temperature alcohol centrifugal extraction and supercritical co2 extraction. Plant oil is obtained from plants through extraction. No matter which extraction method you choose to use, it needs to be filtered, dewaxed, or winterized step after extraction. 



This is because the extracted oil obtained after extraction equipment contains many other ingredients. Such as include residual ethanol, residual water, vegetable oil (the main components are esters from linear higher fatty acids and glycerol), cellulose, lignin, sugars and inorganic salts, vitamins, chlorophyll, flavonoids, alkaloids, terpenes, hydrocarbons , Silver citrate, etc.

 

So we need to choose the right filter equipment to solve the filtration / dewaxing / winterization process. There are also many kinds of filtration equipment, two of which are widely favored by customers. Stainless steel two-stage filtration equipment, its first stage is a bag filter and the second stage is a cartridge filter, which can achieve high-efficiency and high-precision fine  filtration. It is commonly used after ethanol centrifuge extraction process. 



Another is a stainless steel quick-opening filter, which is commonly used after supercritical extraction to achieve dewaxing filtration effect, which can realize automatic feeding and large-volume customization.
