[0038] Furthermore, the stirring mechanism 6 uses the stirring motion of the first blade 64 and the second blade 65, which are respectively installed on the outside of the rotating rod 62 and the inside of the annular rod 63. The unique design of the second blade 65 stirs the raw material deposited on the bottom wall of the tank 1 and lifts it upward, thereby achieving a uniform state that is difficult to achieve during the stirring process and avoiding problems such as excessively high or low concentration in some areas.

This effectively prevents the mixing of air and the contamination of impurities, thereby avoiding the negative impact of these factors on the transparency and smoothness of the gel, and thus reducing the problem of reduced gel appearance quality. The outlet 53 is located at one end of the tank 1. The gel that needs to be stirred enters through the inlet 55 installed on the top surface of the cover 51 and connected to the output end of the external equipment.

[0049] The stirring mechanism 6 uses the stirring motion of the first blade 64 and the second blade 65, which are respectively installed on the outside of the rotating rod 62 and the inside of the annular rod 63.
