Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for decomposing food waste, which decomposes and disposes food waste such as leftover food and cooking waste discharged from general households and restaurants by microorganisms.

[0002]

2. Description of the Related Art A conventional food waste decomposing apparatus for fermenting and decomposing food waste with microorganisms is a method of composting, in which food garbage is accumulated in a container for a long period of time, and then fermented and decomposed.
A device for composting is generally well known, but recently, as seen in Japanese Utility Model Publication No. 6-34784, a fermenting decomposition tank is filled with a microbial carrier such as sawdust, and mechanically stirred with raw garbage. However, there has been devised a device for decomposing food waste that fermenting and decomposing food waste at high speed. This type of food waste decomposition apparatus has a structure as shown in FIG. FIG.
In 1, a fermenting and decomposing tank 1 is filled with a living carrier 2 such as sawdust. 3 is a stirring blade provided in the fermentation decomposition tank 1, 4 is a motor for rotating the stirring blade 3, and 5 is a chain for transmitting the rotation of the motor 4 to the stirring blade 3. 6 is a fan for ventilating the air in the fermentation decomposition tank 1, 7 is an air supply port, and 8 is an exhaust port.

In the above structure, when food waste is put in from the food waste input port (not shown) provided on the front side of the upper surface and the lid of the input port is closed, the motor 4 rotates and the chain 5 causes the stirring blades. Rotate 3. By the rotation of the stirring blades 3, the introduced food waste is mixed and agitated with the habitation carrier 2 in the fermentation decomposition tank 1, and the food waste is crushed and used as a substrate for the assimilation and metabolism of microorganisms. When 6 operates, air is sent from the air supply port 7 into the fermentative decomposition tank 1 to activate the assimilation and metabolism of aerobic microorganisms. And the exhaust port 8 from the fermentation decomposition tank 1 to the atmosphere
The food waste will be reduced and the garbage will be reduced.

[0004]

However, in the above-mentioned conventional construction, it is difficult and excessive to perform the decomposition treatment of the garbage by the aerobic microorganism in the fermentation decomposition tank 1 under the optimum conditions. That is, since it is difficult to properly maintain the temperature and moisture content, which are the rate-determining conditions for the fermentation decomposition of aerobic microorganisms, it is difficult to secure an appropriate fermentation decomposition rate, and the capacity of the fermentation decomposition tank 1 is provided with a margin. . In addition, the inside of the fermentation decomposition tank 1 becomes anaerobic to prevent anaerobic microorganisms from breeding and the fermentation decomposition rate to decrease, to maintain aerobic conditions and to prevent discomfort when a bad odor occurs in the atmosphere. The ventilation air volume of the fan 6 was set to be excessive in order to perform the diffusion process. Therefore, the microorganisms start to decompose and decompose the garbage, and an excessive amount of air exceeding the oxygen amount required for assimilation and metabolism is supplied to the fermentation decomposition tank 1, and when the outside air temperature is low, the fermentation decomposition tank 1 There was a problem that the fermentation temperature in the inside did not rise easily, the decomposition rate slowed down, and the decomposition processing capacity of food waste was small for the size of the device. Further, since the ventilation air volume of the fan 6 is excessively large, the water from the habitation carrier 2 in the fermentation decomposition tank 1 is likely to evaporate, and the operation is often performed in a state where the water content is small, so that the water activity value of the microorganism is lowered. However, this also causes a problem that the fermentation decomposition rate decreases, and similarly, although the apparatus is large, the decomposition processing capacity of food waste is small.

The present invention is intended to solve the above-mentioned problems. While maintaining the aerobic state in the fermentation decomposition tank, the fermentation temperature is ensured to increase, the habitation carrier in the fermentation decomposition tank is prevented from drying, and the assimilation of microorganisms is performed. The purpose is to activate the action and metabolism, to improve the decomposition rate, and to reliably control the bad odor.

[0006]

The present invention has the following constitution in order to solve the above problems.

That is, air-blowing means for supplying and exhausting air to and from the fermentative decomposition tank, and heat radiation fins on both sides of the plate-like Peltier element are provided, and one side of the Peltier element is supplied into the fermentative decomposition tank. A heat control unit that exchanges heat with the air and exchanges heat with the exhaust gas from the inside of the fermentation decomposition tank on the other side of the Peltier element is provided in the ventilation passage of the fermentation decomposition tank. With this configuration, the heat radiation side of the Peltier element can be exchanged with the supply air which is the outside air having a lower temperature than the inside of the fermentation decomposition tank 1, whereby the supply air temperature can be raised, and the assimilation action of the microorganisms in the fermentation decomposition tank 1 can be achieved. It is possible to accelerate the metabolic action, improve the decomposition processing performance of food waste, and reduce the capacity of the fermentation decomposition tank.

(8) State quantity detecting means such as the outside air temperature outside the fermentation decomposition tank or the inside air temperature or humidity inside the fermentation decomposition tank, the DC power source of the Peltier element constituting the heat control unit, the Peltier element and the DC power source A switch for inverting the positive electrode and the negative electrode in the middle of the circuit for connecting the switch and a switch control section for instructing the switch of the switch according to the signal of the state quantity detection means. It is possible to switch between heating the supply air and cooling the exhaust gas from the fermentation decomposition tank, and conversely cooling the supply air and heating the exhaust gas, promoting fermentation by heating the supply air and cooling the supply air. The fermentation can be suppressed and the generation of bad odor can be automatically prevented.

(9) Since the deodorant adsorption mode and desorption mode selection switch are provided and the selection control section for instructing the changeover switch to be instructed by the selection switch is used, the Peltier element is placed in the fermentation decomposition tank in the adsorption mode. The stack space side through which the exhaust gas passes is used as the heat absorption side, and the adsorption of odorous components contained in the exhaust gas is used as a deodorant, and when in the desorption mode, the Peltier element releases heat to the stack space side through which the exhaust gas from the fermentation decomposition tank passes. On the other hand, the temperature of the deodorant can be raised and the odorous components can be desorbed, and the adsorption and desorption of the deodorant can be done by simple switch switching.

(10) A deodorant adsorption mode / desorption mode selection switch is provided, and a selection control unit for instructing the changeover switch to be switched by the selection switch, a blowing means capacity switching means, and a blowing means capacity in the desorption mode. Since it is composed of an air volume control unit that alternately changes the size, the Peltier element in the desorption mode is the stacking space side through which the exhaust gas from the fermentation decomposition tank passes, and the stacking space side is the heat radiating side. The temperature of the deodorant is greatly increased, and the odorous component is easily desorbed, and when the capacity of the blowing means is large, the deodorized component can be diffused, and the deodorant can be regenerated in a short time.
