  • the reverse rotation as described above is part of a driving method to maximize the stirring action, and the load applied to the impeller increases more than when carrying out the forward rotation. Therefore, there exist side blades to withstand the load acting on the circular-arc blade during the reverse rotation.

  • the blade 300 can direct the biologics and food waste toward the inner side of the stirring tank while rotating, whereas if designed in the way as depicted in (B) of Fig. 7, the biologics and food waste are directed toward the wall of the stirring tank, and thus, biologics and food waste may be compressed on the blade surface and the walls of the stirring tank. If the food waste or the like is compressed as described above, an excessive load is generated within the machine to thereby cause vibration therein, and as a result, a trembling phenomenon occurs and a fatigue phenomenon due to vibration is caused in the impeller and the blade, which may be a cause of damage.
  • the ⁇ 4 is preferably designed to be 24 to 70 and the ⁇ 5 to be 120 to 150, and the ratio of ⁇ 4: ⁇ 5 is preferably 1: 2 to 1: 5.

In contrast, if the ratio exceeds 1.3: 1, a phenomenon of turning food waste and biologics into masses may occur even if certain angles are formed between adjacent stirring vanes, which is not desirable.
