A first embodiment of the application provides a fish oil winterization, fractionation and crystallization reactor, as shown in fig. 1, the main body of which comprises an input assembly 100, a control assembly 200 and an output assembly 300, wherein the input assembly 100 comprises a nitrogen inlet 101, and the nitrogen inlet 101 is connected with a nitrogen replacement coil 102 inside the reactor. Nitrogen is introduced into the reaction tank through the nitrogen inlet 101, and the introduced nitrogen "replaces" the gas (e.g., oxygen) in the reaction tank, and the "replaced" gas is discharged from the gas outlet 301 of the output assembly 300 and the breather valve 400 connected thereto. Here, the meaning of "displacing" a gas is as follows: the fish oil is placed in an environment (for example, in air or a bottle tank) for a long time, oxidation occurs, and the oxygen in the environment can be replaced by introducing nitrogen into the reaction tank and discharged from the gas outlet 301. Referring to the schematic diagram of the cross-sectional view of the nitrogen-substituted coil 102 shown in fig. 2, the nitrogen-substituted coil 102 is fixed by a collar 102a and a baffle 102b, and a right-angle side of the triangular block 102c is connected to the collar 102a and a right-angle side is connected to the baffle 102b. Holes 102d are formed in the upper side and the lower side of the nitrogen replacement coil 102, nitrogen in the nitrogen replacement coil 102 is scattered into the reaction tank through the holes 102c to replace gas, so that an anaerobic environment for fish oil processing and storage is ensured, and residual volatile substances can be replaced to the outside of the tank through the gas outlet 301 and the breather valve 400 by nitrogen, thereby being beneficial to product quality.
