Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention ferments raw garbage discharged from general households and dining rooms with enzymes and bacteria,
The present invention relates to a food waste processing machine for decomposing.

[0002]

2. Description of the Related Art A conventional food waste disposer is actually Kaikaihei 5-278.
As shown in Japanese Patent Publication No. 8 (see FIG. 3), in order to ferment and decompose organic matter such as food waste with microorganisms, etc., a medium (scraps) and bacteria are mixed in the processing tank, and the garbage is put into the processing tank After throwing in more, by rotating the handle by rotating the handle and then leaving it to stand, while taking in fresh air from the upper and lower air inlets, the garbage is treated by enzymes and bacteria such as water and carbon dioxide. Was fermented and decomposed.

[0003]

However, in the above-mentioned conventional example, every time the processing tank is rotated, fine media and food waste are spilled from the upper and lower air intakes of the processing tank, and There was a problem of getting dirty around.

Further, since the malodor of food waste during fermentation decomposition in the treatment tank is directly discharged to the outside of the treatment tank, there is a problem that not only the malodor is plagued but also insects gather.

In winter, the functions of enzymes and bacteria are reduced,
There is also a problem that the amount of raw garbage to be processed decreases.

Therefore, the object is to prevent spillage and offensive odor, and to secure a throughput even in winter.

[0007]

The present invention has been made in order to solve the above-mentioned problems, and a treatment tank for receiving food waste and a food waste introduction for receiving food waste into the treatment tank are provided. In a food waste processing machine provided with a mouth, a stirring means for stirring the food waste in the processing tank, and a ventilation passage for ventilating the air in the processing tank, the processing tank is configured to rotate about a fixed shaft, The ventilation passage is provided on both side surfaces of the processing tank through which the fixed shaft passes, and one end is opened inside the processing tank and the other end is opened outside the processing tank with the fixed shaft of the processing tank interposed therebetween. The inside and the outside of the processing tank are communicated with each other.

Further, a heating means for receiving a fermentation accelerating material composed of bio-bacteria or the like in the treatment tank and heating the inside of the treatment tank is provided,
The mixture of food waste and fermentation accelerator was heated to a predetermined temperature.

Further, a honeycomb-shaped low temperature deodorizing catalyst is provided on the outside air side of the ventilation passage to prevent odors from being emitted to the outside air side through the ventilation passage, and a stirring means composed of fixed blades is fixed to the fixed shaft. The mixture of food waste and fermentation accelerator was agitated when the treatment tank was rotated around a fixed shaft.

[0010]

With this structure, the stirring means, which is composed of the fixed blades fixed to the fixed shaft, stirs and cuts the mixture of food waste and the fermentation accelerator when the processing tank is rotated. When rotating around the fixed shaft, even if the opening of the ventilation passage on the treatment tank side sinks in the mixture of finely cut food waste and the fermentation accelerator, the opening of the ventilation passage on the outside air side does not move the fixed shaft. The mixture does not spill because it is above the mixture. At this time, the mixture that has entered the ventilation passage from the opening on the side of the processing tank returns to the inside of the processing tank by its own weight while rotating, so it rotates 180 ° on the contrary and the opening on the outside air side of the ventilation passage becomes downward. But the mixture does not spill.

When the mixture that has entered the opening of the ventilation passage on the processing tank side returns to the processing tank by its own weight due to the rotation of the processing tank, fresh air is sucked from the outside air side of the ventilation passage. When the mixture enters the opening of the ventilation passage on the processing tank side, the air in the processing tank is pushed out to the outside air side, and by repeating this, the air in the processing tank is automatically ventilated. Therefore, the aerobic reaction of food waste can be carried out in the entire processing tank, and the generation of bad odor is reduced.

Further, the fermentation accelerating material composed of bio-bacteria or the like accelerates the fermentation decomposition treatment of the garbage, and the heating means provided in the treatment tank heats and maintains the mixture of the garbage and the fermentation accelerating material at a predetermined temperature. It has the function of fermenting and decomposing enough even in the winter season to secure the processing amount.

The honeycomb-shaped low-temperature deodorizing catalyst provided on the outside air side of the ventilation passage deodorizes the offensive odor of food waste during fermentation and decomposition so that no odor is emitted to the outside air side through the ventilation passage.
