With the development of citrus processing industry, the problem of the treatment of citrus pomace has become increasingly prominent and has gradually attracted attention. Disposal of citrus peels not only causes waste of resources, but also pollutes and endangers the environment, which has become one of the important factors restricting the scale development of citrus industry. How to effectively deal with citrus peels has become an urgent problem to be solved.

The existing citrus peel residue mainly extracts essential oil when extracting essential oil. Essential oil is an oil-soluble component. The traditional citrus peel essential oil oil extraction process generally uses needle type, tooth type oil mill or screw type oil press. Or steam distillation to extract the crude oil, and then separated by disc centrifuge or plate separator to obtain essential oil. The extraction of essential oils by butterfly centrifuges or plate separators is relatively extensive, and it is difficult to extract all types of aromatic components and increase the extraction amount of aromatic components.
