However, there is a problem that the food waste treatment material and the food waste are easily clogged.

Further, in the conventional example, when the air ejection port is clogged with deposits, in order to eliminate the clogged deposits, the garbage processing material contained in the garbage disposal tank is removed. ,
Not only is there a problem that it takes time and labor to clean the air jets and remove the clogged deposits by hand, it also gets inside the hollow part of the stirring shaft or spiral stirring blade and hardens. There is a problem that the accumulated deposits cannot be removed.

Further, in any of the conventional examples, it is not possible to detect that the air outlet is clogged, and the operation is continued as it is in a state where the air outlet is clogged and sufficient air is not supplied, and sufficient garbage There is a problem that the next garbage will be put in without being processed, and the capacity of the garbage processing material will decrease due to overload, and the effective use period of the garbage processing material will be shortened. is there.

In the conventional example disclosed in Japanese Patent Laid-Open No. 8-84980, a heater wire is inserted in the hollow portion of the spiral stirring blade to heat the air jetted from the air jet port. As described above, since the food waste treating material enters the hollow portion inside the spiral stirring blade from the air ejection port, if the food waste treating material touches the heater wire, there is a possibility that a problem such as fire may occur. Further, in the conventional example, the waste heat of the high-temperature exhaust gas exhausted from the food waste treatment tank and the waste heat generated from the power unit for rotating the stirring shaft have not been effectively used.

As described above, by performing the operation of switching to the high-pressure jet mode in which the high-pressure air is jetted from the air jet 6 at regular intervals, the air passages from the air jet 6 to the stirring blades 4 and the stirring shaft 3 are formed. Even if the garbage processing material 15 or the garbage is contained in the hollow portion 14, the hollow portion becomes the air passage of the stirring blade 4 and the stirring shaft 3 by supplying high-pressure air having a pressure higher than the air pressure in the normal air ejection mode. The food waste treatment material 15 and the food waste accumulated on 14 can be forcibly blown out and discharged from the air ejection port 6 for cleaning. Further, since high-pressure air is supplied for cleaning in this manner, air can be supplied to microorganisms inhabiting the food waste processing material 15 by blowing air for cleaning into the food waste processing material 15. Therefore, it is possible to clean without waste while saving energy.

Another embodiment is shown in FIGS. In the present embodiment, a pressure detection unit 9 that detects the pressure of the air ejected from the air ejection port 6 is provided, the detection data of the air pressure detected by the pressure detection unit 9 is sent to the control unit 18, and the foreign matter is determined beforehand by the determination unit 10.
