Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention decomposes general biological garbage discharged from food processing sites such as kitchens and food factories such as homes, and fields such as fields such as vegetables. The present invention relates to a method and an apparatus for treating garbage. In particular, the present invention relates to a configuration for effectively deodorizing a processed product.

[0002]

2. Description of the Related Art Various types of garbage disposal apparatuses for biodegrading garbage are already available on the market. For example, a garbage fermentation processing apparatus including a processing unit that ferments garbage, a collection unit that collects the fermented processed product, and a deodorizing exhaust unit that deodorizes and exhausts the odor from the processing unit is It is known. In this type of garbage processing apparatus, garbage is first charged into a fermentation treatment tank of a processing section together with a fermentation promoting material such as fermentation bacteria. The introduced garbage is stirred by a rotary stirring claw provided in the fermentation treatment tank, and fermentation aging is promoted. The processed product subjected to the fermentation process is stored in a processed product recovery device of the recovery unit. Then, the final product is reused as fertilizer or the like.

[0003] The deodorizing exhaust section is provided with a thermal catalyst contributing to deodorizing, a heater for heating the thermal catalyst, and an exhaust fan for exhausting. Conventionally, the heater for a thermal catalyst and the exhaust fan have always been operated at the same output. Then, when it is desired to raise the temperature of the thermal catalyst for the purpose of deodorization, the thermal catalyst may be cooled by wind from the exhaust fan. Conversely, if there is almost no need for deodorization and you want to ventilate and dry the processed material with the wind from the exhaust fan,
Electric power wasted without the need to raise the temperature of the thermal catalyst.

[0004] In general, during the fermentation and ripening of garbage, the concentration of odor is high. Therefore, if the lid of the fermentation treatment tank is opened or the operation of the rotary stirring claw is set to the discharge operation, the odor may be diffused. As described above, conventionally, there has been no configuration for minimizing the odor emitted outside the apparatus.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to effectively deodorize a processed material and minimize odors emitted outside the machine. It is an object of the present invention to provide a method for treating garbage and an apparatus for implementing the method.

In the garbage disposal apparatus, an odor sensor is provided in an odor guide duct that communicates between a processing tank of a processing unit that accommodates garbage and a deodorizing case of a deodorizing exhaust unit, and an odor concentration detected by the odor sensor. The operation of the heating means of the thermal catalyst provided in the deodorizing exhaust unit and the operation of the exhaust unit are controlled according to the magnitude of the exhaust gas.

Here, if the odor concentration is higher than a predetermined threshold, the heating of the thermal catalyst may be enhanced to contribute to the improvement of the deodorizing performance.

[0008] Further, the exhaust air volume may be reduced to contribute to the maintenance of the temperature rise of the thermal catalyst and power saving.

Conversely, if the odor concentration is smaller than a predetermined threshold, the heating of the thermal catalyst may be reduced to contribute to power saving.

[0010] The exhaust air volume may be increased to contribute to the improvement of drying performance.

If the odor concentration is higher than a predetermined threshold,
The rotary stirring claw provided in the processing tank is set to the stirring operation, and if the rotation stirring claw is smaller than a predetermined threshold, the rotation stirring claw is set to the discharge operation to prevent the odor from being emitted with the operation of the rotary stirring claw. Is also good.

If the odor concentration is greater than a predetermined threshold,
A display for stopping the input of the raw garbage may be displayed to prevent the odor from being diffused with the opening of the fermentation treatment tank.

An apparatus for realizing such a method for decomposing garbage includes a processing section for biodegrading and processing garbage, a recovery section for recovering the biodegraded processed material, a processing section or a recovery section. In a garbage disposal device equipped with a deodorizing exhaust unit that deodorizes and exhausts odors from the unit, the odor guide duct that connects the processing tank of the processing unit that stores the garbage and the deodorizing case of the deodorizing exhaust unit , An odor sensor, and using the odor concentration detected by the odor sensor as a parameter, a deodorizing exhaust control device that controls the operation of the heating means of the thermal catalyst provided in the deodorizing exhaust part and the operation of the exhaust means.

Packaging materials and containers formed of biodegradable plastics using these polymers as raw materials are also decomposed. for that reason,
The raw garbage can be put into the processing unit and decomposed without being separated from the packaging material and the container.
