Abstract

PROBLEM TO BE SOLVED: To lessen the deterioration of the indoor environment. SOLUTION: When starting operation of drying treatment is done, a stop valve 61 is opened and also a disposal tank 21 is heated by a heater 31. As a result, the temperature of the inside of the disposal tank 21 and a heating chamber 30 is raised so that moisture begins to evaporate from garbage A in the disposal tank 21. At a point of time when the steam is in the condition where the heating chamber 30 and a condensing chamber 40 are filled with it, the stop valve 61 is closed to shut them tightly, and a fan 50 is operated to cool and condense the steam in the condensing chamber 40. Consequently the steam generated in the heating chamber 30 flows in the condensing chamber 40 to make the inside of heating chamber 30 vacuum and lower the boiling point of water, allowing the moisture to be evaporated at a lower temperature. Almost all malodorous components generated from the garbage are dissolved into the condensed water, which is drained to a drainpipe 1 during drying treatment or after drying treatment.

A condenser for cooling and condensing steam, a discharge path for discharging water condensed in the condenser to the outside, an opening / closing means for opening and closing the discharge path, a heating section and a condenser for closing the opening / closing means. The gist of the present invention is to perform a drying process in which the kitchen is heated by the heating unit to evaporate water while condensing water vapor in the condensing unit in a state where the space communicating with the airtight is sealed.

According to a second aspect of the present invention, there is provided a kitchen waste treatment machine according to the second aspect of the present invention, wherein the heating unit heats the kitchen waste to evaporate water with the opening / closing means opened before the drying process. The gist of the present invention is to perform a pretreatment for replacing air in a closed space with steam.

In the kitchen waste treatment machine according to the first aspect of the present invention having the above structure, the heating unit heats the kitchen waste in a state where the opening / closing means is closed and the space communicating the heating unit and the condensation unit is sealed. The water vapor is cooled and condensed in the condensing section while evaporating the water. And since most of the odor generated from the kitchen garbage dissolves in the condensed water, by opening the opening and closing means at a predetermined timing and discharging the condensed water to the outside (for example, a sewer pipe),
The odor component is discharged together with the condensed water, so that a deodorizing device is not required. Moreover, it is possible to prevent a large amount of water vapor that is not condensed from being discharged by sealing and drying.

Further, the present invention has the above-mentioned structure.
The garbage processing machine described performs a pre-treatment of discharging air by heating the garbage in a heating unit in a state where the opening / closing means is opened, evaporating moisture, and filling with steam. Then, when the drying process is performed by closing the on-off valve, a negative pressure can be obtained by condensing water vapor in the condensing section in a state where the space communicating with the heating section and the condensing section is sealed. Therefore, odor leakage can be prevented, and the boiling point is reduced, so that the drying treatment can be performed at a low temperature. Here, the pretreatment is not limited to the one performed at the start of the drying operation. For example, even during the drying operation, it may be appropriately performed when a negative pressure is required.
