The juice in the heating tank 1 is stirred by the first stirring blade group and the second stirring blade group.

[0018] The first stirring blade assembly includes multiple first stirring elements 6 spaced apart on the annular outer periphery of the stirring shaft 5, such as two, three, four, etc.; the first stirring element 6 includes a first stirring body 7, two first vertical stirring blocks 8, and two second vertical stirring blocks 9; the inner end of the first stirring body 7 is welded and fixed to the outer peripheral surface of the stirring shaft 5. All the inner ends of the first stirring bodies 7 can be directly welded and fixed to the stirring shaft 5, or they can be first fixed and welded to a mounting ring, and then the mounting ring is fitted or welded to the stirring shaft 5. The outer end of the first stirring body 7 extends toward the inner wall of the heating tank 1, and the outer end forms an upward-curved arc-shaped outer end 10; the two first vertical stirring blocks 8 are vertically spaced and fixed above the first stirring body 7; the two second vertical stirring blocks 9 are vertically spaced and fixed below the first stirring body 7; the vertical stirring blocks on adjacent first stirring elements 6 are not on the same rotational circumference.

[0019] The first stirring element 6 agitates the liquid within the heating tank 1 by employing a first vertical stirring block 8, a second vertical stirring block 9, an arc-shaped outer end, and vertical stirring blocks rotating on different trajectories. This increases the stirring capacity of the first stirring element 6 within the heating tank 1, allowing the liquid in the heating tank 1 to heat up rapidly and evenly, achieving efficient sterilization.
