[0002] Fish oil is a type of oil extracted from fatty fish. It is rich in eicosapentaenoic acid, docosahexaenoic acid and various n-3 polyunsaturated fatty acids. The raw materials for making fish oil preparations are common in mackerel, herring, tuna, flounder, salmon, cod liver, whale fat, seal oil, etc. A small amount of vitamin E is usually added to play an antioxidant role.

[0003] During the production of fish oil, it is necessary to continuously provide fish paste through a feeding device to facilitate the subsequent squeezing of oil.
