Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for promoting the fermentation of organic matter, and more particularly, it can accelerate fermentation of organic matter by utilizing the heat of fermentation when fermenting organic matter such as food waste and animal excrement. The present invention relates to a fermentation promoting device for organic matter.

[0002]

2. Description of the Related Art Food waste such as raw garbage produced from homes and residual materials produced from food factories are collected by a cleaning bureau or a prescribed company and disposed of by incineration or landfill.

Also, animal excrements such as animal excrement are collected by a cleaning bureau or a predetermined trader and treated by incineration or landfill, like food waste.

Furthermore, the branches and leaves of plants such as street trees that have been cut down by pruning are buried in the ground for incineration or as compost.

[0005]

By the way, as a conventional treatment method for food waste, animal excrement, branches and leaves of plants such as street trees, there are incineration and burial as described above.

[0006] However, incineration has the disadvantages that the cost is high, it is economically disadvantageous, the treatment of ash after incineration becomes a problem, and there is a risk of causing air pollution. Further, in the case of burial, it takes a long time to change to soil, and there is an inconvenience such as giving off a strange odor. Further, due to such inconvenience, illegal dumping may be caused and natural destruction may be caused.

Therefore, it is conceivable that fermenting bacteria are allowed to act on such organic substances such as food wastes to ferment them into fermented products and reused as culture soil.

However, when the organic matter is fermented, there is a problem that a long fermentation time is required until the organic matter is completely ripened, and the fermentation time is long, which is disadvantageous in terms of cost. , Improvement was desired.

[0009]

Therefore, according to the present invention, in order to eliminate the above-mentioned inconvenience, food waste, animal excrement, which is an organic matter, and branches and leaves crushed into small pieces are mixed to form a mixture. The mixture is provided with an aerobic fermenting bacterium, and a fermentation heat receiving means for collecting the fermentation heat generated when the mixture is fermented by the aerobic fermenting bacterium and supplying the mixture to the mixture is provided. Characterize.

[0010]

According to the structure of the present invention, when aerobically fermenting bacteria are mixed in a mixture of organic matter such as food waste to ferment it into a fermented product, fermentation heat is generated. This fermentation heat is received by the fermentation heat receiving means and supplied to the mixture. Thereby, the activity of the aerobic fermenting bacteria mixed by heating the mixture can be activated.
