Existing technology usually uses low-temperature sealing to can fish oil for storage.

[0003] For example, the Chinese patent application number CN202220375126.7 discloses a low-temperature storage device for fish oil processing, comprising a fixed box, the front end face of which is provided with a door panel, the inner bottom end face of which is fixedly provided with a base, the upper end face of which is provided with a placement groove, the interior of which is provided with a drain pipe, and nitrogen is used to cool the storage tank body to achieve the effect of low-temperature storage of the fish oil to prevent it from deteriorating. However, in actual use, it was found that the low-temperature sealed storage method, although it can suppress the formation of trans fatty acids in fish oil to a certain extent in a short period of time, still exceeds the standard when tested again after a period of storage, resulting in substandard fish oil products. Utility Model Content

[0006] A solvent chamber, the solvent chamber being mounted on the upper end of the storage tank body via a fixed shaft, and having an opening at a side end thereof;

[0007] a partition plate inserted into the opening to separate the communicating area between the solvent chamber and the inner cavity of the storage tank body;

[0008] an upper stirring blade, wherein the upper stirring blade is installed in the solvent chamber;

[0009] A lower stirring blade, wherein the lower stirring blade is installed in the inner cavity of the storage tank body;

[0010] A driving mechanism for driving the upper stirring blade and the lower stirring blade to rotate is installed at the upper end of the solvent chamber.

[0011] Furthermore, the driving mechanism includes:

[0012] a drive motor, the drive motor being mounted at the upper end of the solvent chamber;

[0013] A rotating shaft is coaxially mounted on the output end of the driving motor, and the upper stirring blade and the lower stirring blade are respectively fixedly mounted on the rotating shaft.
