Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste disposer for decomposing food waste with microorganisms, and more particularly to a food waste disposer capable of easily uniformizing the temperature of food waste in a tank.

[0002]

2. Description of the Related Art In order to treat food waste with a food waste disposer, it is necessary to blow air into a processing tank in order to supply oxygen to microorganisms. In addition, it is necessary to evaporate the water generated by the decomposition of raw garbage. In addition, the food waste is heated to accelerate the decomposition of the food waste, or conversely, the heat of decomposition of the food waste raises the temperature in the processing tank.
It is necessary to cool the garbage in order to keep the inside of the tank at an appropriate temperature of about 60 ° C.

In order to meet such needs, a heater for heating raw dust is provided in the treatment tank, and air is forcedly supplied to the bottom of the treatment tank by a pump.

[0004]

The above-mentioned conventional examples have the following problems (1) to (3). It is not easy to heat food waste uniformly. Since the air pressure loss when passing through the garbage layer is large, the power cost increases. Excessive aeration lowers the temperature in the tank and reduces the activity of microorganisms. Air tends to flow unevenly.

[0005]

According to a first aspect of the present invention, there is provided a garbage disposal machine comprising a stirring shaft and a stirring blade projecting from the stirring shaft in a garbage disposal tank. The stirring blade is provided with a heater.

According to a second aspect of the present invention, there is provided a garbage disposal device in which a stirring shaft and a stirring blade protruding from the stirring shaft are installed in a garbage disposal tank. The inside of the stirring blade is made hollow, an air outlet is provided in the stirring blade, and an air supply device is connected to the stirring shaft.

According to a third aspect of the present invention, there is provided the garbage disposal according to the second aspect, further comprising a heater for heating the air from the air supplier.

[0008]

In the garbage disposal according to the first aspect of the present invention, the stirring blade is heated by the heater, and the heated stirring blade rotates in the processing tank and comes into contact with the garbage. The raw garbage is heated uniformly.

In the garbage disposal according to the second aspect, air is blown out from the outlet of the stirring blade, and the stirring blade rotates in the treatment tank to come into contact with the garbage. The air will come to hit you.

According to the third aspect of the present invention, since the air is heated, it is possible to uniformly apply the heated air to the whole raw garbage.

[Embodiment] FIG. 1 is a cross-sectional view of a garbage disposal according to the embodiment,
FIG. 2 is an enlarged sectional view taken along the line II-II of FIG.

A porous plate 2 is arranged at the bottom of the processing tank 1, an air receiving chamber 3 is provided below the porous plate 2, and air is introduced into the air receiving chamber 3 by an air pump 4. An agitating shaft 6 and an agitating blade 7 projecting from the agitating shaft 6 are supported and supported by bearings 8 in the garbage collecting chamber 5 on the upper side of the porous plate 2. One end of the agitating shaft 6 is It is connected to the motor 9. The agitation shaft 6 and the agitation blade 7 are hollow, and their interiors are in communication with each other.

The other end of the stirring shaft 6 is open to the air introducing chamber 10, and the air introducing chamber 10 communicates with the air receiving chamber 3. A heater 11 is installed in the stirring shaft 6 and the stirring blade 7. The agitation shaft 6 and the agitation blade 7 are provided with air outlets 6a and 7a, respectively.

At the upper part of the processing tank 1, there are provided a garbage introduction port 13 with a lid 12 and an exhaust port 14. An air heater 15 is provided along the lower surface of the porous plate 2.

The lid 12 is opened, and the garbage is put into the garbage storage chamber 5, the stirring blade 7 stirs the garbage, and the pump 4 supplies air into the air receiving chamber 3 to heat the heaters 11, 1.
Energize 5. As a result, warm air is blown out from the air outlets 6a and 7a and the perforated plate 2 to heat raw garbage and remove excess moisture. When the temperature in the processing tank 1 becomes 60 ° C. or higher, the energization of the heaters 11 and 15 is stopped, and air at room temperature is blown to remove heat from the garbage.

When the humidity in the processing tank 1 is low,
Make the air blowout very weak or, in some cases, stop it. In this state, when the temperature inside the processing tank 1 is low, the heater 11 is energized while rotating the blades 7, and the heat of the heater 11 heats the garbage in the processing tank 1.

With this, the necessary and sufficient oxygen is supplied to the microorganisms, and the inside temperature of the garbage layer is maintained at an appropriate temperature of about 60 ° C. to sufficiently enhance the microbial activity and to perform the microbial treatment of the garbage. You can

[0018]

As described above, according to the garbage disposal of the present invention, it is possible to blow air from the impeller or to heat the blown air while rotating the impeller. Further, it is possible to heat the stirring blades with a heater and heat the garbage with the heat of the heater while stirring the garbage. Therefore, according to the present invention, it is possible to uniformly heat the raw garbage and to uniformly remove the humidity, and the raw garbage can be efficiently treated with highly active microorganisms.
