The function of each device of the system of the present invention configured as described above will be described with reference to the drawings. The food waste transferred from the hopper 10 by the food waste moving means 16 is put into the stirring cylinder 20A of the stirrer 20 and the heating means mounted in the housing 20B is operated. The heat generated by the operation of the heating means heats the heat carrier oil stored in the housing 20B, and thereby the heat carrier oil heats the stirring cylinder 20A.

It is in. The steam whose temperature has risen in this way (in a state in which the malodorous component has been removed) is subsequently used in the space S formed on the outer wall of the stirring cylinder 20A.
After flowing through 20, it flows into the space S30 formed on the outer wall of the fermenter 30.

Space portion S3 formed on the outer wall of the fermenter 30
The high temperature steam flowing into 0 undergoes heat exchange with the food waste introduced into the fermenter 30 in the process of passing through the space S30, and in particular, the space S20 formed on the outer wall of the stirring cylinder 20A described above. As described above, since the path of the steam flow is maximized by the large number of extension pieces 31A and 32A, more effective heat exchange is performed.

As described above, according to the present invention, the energy source required for fermenting the food waste in the fermenter 30 is secured by utilizing the high temperature steam discharged from the stirrer 20, especially the deodorizing device 100, so that the energy saving effect is obtained. Of course it is excellent. On the other hand, the malodorous steam generated by the fermentation of the food waste inside the fermenter 30 passes through the steam inflow line L connected to the internal space of the fermenter 30 to remove the deodorizing device 1
It flows into 00. As a result, the malodorous vapor generated from the food waste fermented in the fermenter 30 flows along with the malodorous vapor generated inside the stirring tube 20A along the above-described route and is heated, so that the malodorous component contained in the vapor is generated. Burned.

On the other hand, in the line L2 connecting the discharge portion S30B of the space S30 formed on the outer wall of the fermenter 30 and the inlet S11 of the space S10 formed on the outer wall of the hopper 10, the first activated carbon is added. A heat exchanger 42 different from the casing 41 is provided. The steam discharged from the space S30 formed on the outer wall of the fermenter 30 contains foreign substances and malodorous components to some extent, so that the first activated carbon casing 41 removes foreign substances and malodorous components. The cleaner air will be discharged.
Fresh external air is introduced into the heat exchanger 42, and the new air exchanges heat with the relatively high temperature air introduced from the first activated carbon casing 41. The fresh air whose temperature has risen due to the heat exchange flows into the stirring cylinder 20A of the stirrer 20 and the fermentation tank 30, and the relatively high temperature air that has undergone the heat exchange is the space S formed on the outer wall of the hopper 10.
Inflow to 10.

The high temperature steam that has flowed into the space S10 formed on the outer wall of the hopper 10 through the above-described process exchanges heat with the food waste existing inside the hopper 10 while passing through the space S10. The stirring cylinder 20B
In the space S10 like the fermenter 30, the plurality of extension pieces 11A and 12A maximize the steam flow path, so that more effective heat exchange is performed. As a result, the food waste is preheated to a certain temperature in the hopper 10 and then put into the stirrer 20.
