Recently, a dry-type garbage disposal machine has been proposed to treat garbage such as cooking scraps. The dry type garbage processing machine is provided with a treatment tank for stirring the garbage, provided with a moisture removing means for removing the moisture generated by the garbage, and provided with an air feeding means for feeding the air from which moisture has been removed, An air heating means for heating the supplied air and feeding it into the treatment tank is provided, and the garbage in the treatment tank is heated by stirring with the heated air to remove moisture to dry.
[0003]
As such a garbage processing machine, there are a drying unit having a stirring means for stirring the soot and a discharge port for discharging the treated soot, a deodorizing device having a catalyst and a heater, and steam when drying the soot. Is provided with a condensing device and a blower, and these are connected via a circulation path (for example, see Patent Document 1).
[0004]
In addition, as a garbage processing machine, the garbage in the heating tank is heated and air is supplied, and the steam generated from the garbage is introduced into the condenser together with the exhaust air to condense and reduce the volume of the garbage. (For example, refer to Patent Document 2).

[Problems to be solved by the invention]
By the way, in order to heat the garbage in a processing tank, the conventional dry type garbage processing machine heats air with an air heating means and sends it to the processing tank. The air heating means heats the air sent to the processing tank by a heater provided in the box. Since the box body has a problem of heat leaking to the outside when the heat of the heater is transmitted to the surface, a heat insulating material is provided inside.
[0007]
However, the box provided with the heat insulating material only slows the time during which the inner heat is transmitted to the surface and lowers the temperature rise rate of the surface, and cannot lower the surface temperature.
[0008]
For this reason, the conventional dry-type garbage disposal machine cannot reduce heat leakage to the outside, and heat escapes, resulting in a disadvantage that energy consumption increases.
[0009]
[Means for Solving the Problems]
Therefore, in order to eliminate the inconvenience described above, the present invention provides a treatment tank for stirring the garbage, a moisture removing means for removing the moisture generated by the garbage, and supplying the air from which moisture has been removed. Air supply means is provided, air heating means is provided to heat the supplied air and send it to the treatment tank, and the garbage in the treatment tank is stirred while heating with heated air to remove moisture. In the type garbage disposal apparatus, the air heating means is provided with an outer box that communicates with the air feeding means and an inner box that is disposed within the outer box and communicates with the treatment tank. A communication hole communicating with the inside of the box is provided, and a heater for heating air is provided in the inner box.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The dry type garbage processing machine of the present invention is for removing moisture by stirring while heating the garbage in the treatment tank with heated air, and the air heating means for heating the air and feeding it to the treatment tank, An outer box that communicates with the air supply means is provided, and an inner box that is disposed in the outer box and communicates with the treatment tank is provided, and a communication hole that communicates with the inside of the outer box is provided in the inner box, By providing a heater that heats the air, the air supplied by the air supply means flows between the outer box and the inner box, enters the inner box through the communication hole, and is heated by the heater in the inner box for processing. Since it is sent to the tank, the heat leaking from the inner box can be absorbed by the air flowing between the outer box and the inner box, and the air before entering the inner box between the outer box and the inner box can be absorbed. It can be preheated by heat leaking from the inner box.
