However, since the devices according to other conventional examples are operated by the manual switch devices by the analog method, the operation is inconvenient, and there is a problem that the drive by the automatic or manual mode can not be selected. In addition, since the hot water can not be injected into the shell case (stirring tank), there is a problem that the disposal processing ability of the food waste is deteriorated, and the inside of the shell case (stirrer) can not be cleaned, .

No. 10-0808132 filed by the present applicant and filed by the present applicant, a system for disposing food waste, a system for disposing food garbage, The apparatus disclosed in the Japanese Patent Application Laid-Open No. 2000-348999) is disadvantageous in that it takes a lot of time to disassemble, which leads to deterioration in efficiency, deterioration of noxious gas and extreme odor due to discharged food waste, And the automatic or manual mode can not be selected. In addition, since hot water can not be injected into the shell case (agitator), the disposal processing ability of the food waste is deteriorated, It is impossible to cleanly clean the stomach.

However, the patented food waste disposal device (or the disposal system device) of the present applicant has a problem in that, in discharging the residues generated after the biological decomposition process using microorganisms to the sewage, There is a problem. These problems may lead to inaccessibility in some countries, so additional equipment is required to improve the quality of the sewage.
