Referring to the operation of the food waste drying weight reduction apparatus that can be applied to the embodiment of the present invention made as described above are as follows.

The user opens the lid 13 provided in the case 1, puts food waste in and closes the lid 13. And the user operates the switch (not shown) to operate the food waste drying weight reduction device.

Then, the control unit C drives the drive source (not shown), the rod heater 27, the blower 39, and the cooling fan 33 of the stirring unit 5.

 As the rotating shaft 15 of the stirring unit 5 rotates, the first connecting member 17, the second connecting member 19, and the stirring blade 21 are rotated. 1 The connecting member 17, the second connecting member 19 and the stirring blade 21 is rotated to mix the food waste evenly in the treatment tank (3).

As described above, the first connecting member 17 and the second connecting member 19 may be formed when the metal stick, such as a cutlery included in the food waste, is caught on the inner wall of the treatment tank 3 and the tip of the stirring blade 21. Agitation can be continued by moving relative to each other.

And the temperature-humidifier (溫濕 臭氣) in the inside of the processing tank 3 is transmitted to the condenser 31 through a pipeline. At this time, inside the condenser 31, condensate is generated by a temperature difference from the outside of the condenser 31, and flows downward along the inner conduit of the condenser 31.

At this time, the condensate flowing along the inner conduit 31 prevents foreign substances such as dust and corrosive gas particles from being attached to the inner wall of the condenser 31. Therefore, it is possible to prevent corrosion of the inner conduit of the condenser 31.

The dry air passing through the condenser 31 is supplied to the dry air supply unit 29 through a pipe line.

The dry air supplied to the dry air supply unit 29 is warmed by the heat of oil contained in the oil jacket 23 while passing through the air passage line 29b through the inlet 29d.

The embodiment of the present invention does not require a separate air heating device because the heat source for heating the treatment tank 3 is used as it is without using a separate heat source when supplying the dry air to the treatment tank 3. Therefore, it is possible to continuously supply the warmed air into the treatment tank (3) through a simpler configuration.

While repeating this process, it is possible to dry the food waste inside the treatment tank (3).

Such an embodiment of the present invention can maximize the food waste disposal efficiency while increasing the durability while preventing the odor smell in the treatment process because the hot and humid odor (온) in the treatment tank is not exposed to the outside It can reduce the cost of maintenance and increase the utilization rate.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
