BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste processing apparatus for decomposing food waste.

[0002]

2. Description of the Related Art Conventionally, sludge containing organic matter and water has been decomposed (fermented) to the extent that it does not affect the environment by utilizing microorganisms. Are known. This food waste treatment device is a porous wood particle as a food waste treatment material in which microorganisms called horror agents live in the treatment tank (for example, Japanese Patent Publication No. 2-1.
0398, Tokuhei 2-30760, Actual Fair 3-22
No. 385). Then, the garbage is put into the treatment tank through the inlet provided in the treatment tank, and the garbage processing material in which microorganisms inhabit and the garbage are mixed and the air is brought into contact to inhabit the garbage processing material. The microorganisms are decomposed and water is evaporated at the same time. Japanese Utility Model Publication No. 5-88683 has been proposed as an apparatus for treating such garbage.

Further, in the garbage processing apparatus, one in which a stirring blade is provided in the processing tank has been proposed by Japanese Patent Laid-Open No. 4-4084. Further, there is a garbage container that only contains raw garbage (that is, one that simply puts the raw garbage without decomposing it) and deodorizes it by generating ozone from an ozone generator. It is known from Japanese Patent No. 48701. In addition, a garbage container that only stores garbage (that is, one that is simply stored without decomposing the garbage) is provided with a deodorant spraying device for spraying the deodorant. No. 172505.

Further, in a food waste processing apparatus provided with a processing tank 1 containing a food waste processing material for decomposing food waste, and a stirring means 2 arranged in the processing tank 1, during stirring of the stirring means 2 and It is also preferable to automatically supply a malodor eliminating agent such as a deodorant or an aromatic agent into the processing tank 1 immediately after the end of stirring.

It is also preferable to reduce the amount of exhaust air when stirring by the stirring means 2.

[0010]

According to the present invention having the above-mentioned structure, the odor accumulated and adsorbed by the raw food waste treating material which is the carrier when the agitating means 2 is agitated is temporarily agitated in the raw food waste treating tank 1. Since a large amount is released to the upper space of, the odor eliminating agents such as deodorants and fragrances should be treated as raw garbage at the same time as this, at the time of stirring, immediately after the stirring is completed, or during and immediately after the stirring. By automatically supplying into the processing tank 1, the odor generated by stirring can be efficiently eliminated by the malodor eliminating agent.

By reducing the amount of exhaust air during stirring by the stirring means 2, a large amount of odor generated during stirring is not exhausted to the outside and the surrounding environment is not deteriorated, and the malodor is eliminated in the processing tank 1. The agent can effectively eliminate the bad odor.
