DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for decomposing garbage using the power of microorganisms.

[0002]

2. Description of the Related Art Conventionally, sludge containing organic matter and water has been decomposed (fermented) using microorganisms so as not to affect the environment. Are known. In this garbage disposal apparatus, wood chips (for example, Japanese Patent Publication No. Hei 2-30760) filled with biochips are filled in a garbage disposal tank as a garbage disposal material. The garbage is introduced into the garbage processing tank from an input port provided in the garbage processing tank, and the garbage is fermented by the action of microorganisms living in the garbage processing material to be decomposed. When the microorganisms are fermented and decomposed by the action of microorganisms, the stirring means is rotated to supply oxygen to the garbage disposal material.

SUMMARY OF THE INVENTION In the above-mentioned conventional garbage processing apparatus, the garbage processing material 2 after the garbage is charged.
As a result, a result as shown in the graph of FIG. 5 was obtained. In this measurement, as shown in FIG. 6, the temperature of the lower point A in the garbage processing tank 1 was measured, and the garbage processing material 2 was uniformly stirred by the stirring means 4. The outside air temperature at this time was 25 ° C.

As is clear from the graph of FIG. 5, the temperature of the garbage is 25 ° C. at the time of input, and then the garbage is decomposed by the action of microorganisms inhabiting the garbage processing material. Eight hours after the introduction, the temperature of the food waste treatment material reached a peak due to the heat of reaction, and this temperature was 45 ° C. Then, after the peak temperature of 45 ° C., the temperature of the garbage disposal material gradually decreases,
It will be 5 ° C. When the garbage is put in again, the same temperature change as above is repeated.

However, as described above, only the heat generated by the decomposition of garbage by microorganisms inhabiting the garbage disposal material reaches only 45 ° C. after 8 hours, so that the organic matter decomposition rate is 70% on average. There was only. Therefore,
The remaining 30% has a problem that it remains as an undecomposed product, resulting in poor processing efficiency and a long processing time. Furthermore, food poisoning bacteria such as Salmonella and Staphylococcus could not be sterilized at 45 ° C.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and can speed up the decomposition rate of garbage disposal, increase the decomposition efficiency, and can surely sterilize food poisoning bacteria. It is an object to provide a garbage processing device.
