The switching valve 91 is held at the neutral position by the signal of the temperature sensor in the process of (1). In this process, the dust of the processed material floats in the tank 51 due to the temperature rise and the stirring of the tank 51, and the dust is introduced into the cyclone 81 together with the hot air (exhaust gas), and the dust is collected and placed in the dust box 92. The accumulated hot air is sucked into the circulation fan 86 from the air outlet 81b of the cyclone 81, and
A part of the hot air blown out from the duct 6 is transferred into the tank 51 by the switching valve 91, and the other part is discharged as the exhaust gas.

The duct 90 is in a state of being stored at substantially the same temperature because it is horizontally laid in the high temperature range T1 of 0 ° C., so that the offensive odor in the exhaust gas is directly contacted with this high temperature and deodorized.
It is released to the atmosphere via the duct 90.

とがない。As described above, in the deodorizing fermentation drying apparatus 50 of the present embodiment, the organic waste is fermented and dried at a high speed to obtain a finished product as in the prior art. In particular, a circulation / discharge path 87 is provided between the drying tank 51 and the cyclone 81 to circulate hot air until the temperature atmosphere in the drying tank 51 substantially reaches the predetermined high temperature range T1 and low temperature range T2. Since it is supplied, energy can be saved, and the exhaust gas passes through a heat storage deodorizing duct 90 which is separated from the circulation path and extends in the discharge path in a high temperature range T1 of 700 to 850 ° C. Therefore, the inside of the duct 90 is in a state where heat is stored at substantially the same temperature, so that the odor in the exhaust gas is directly contacted with this high temperature and is deodorized, and is released to the atmosphere through the duct 90, so that the odor is More is not to affect the environment of the surrounding area.

とがない。As described above, the deodorizing fermentation drying apparatus of the present invention is constructed as described above, so that the organic waste can be fermented and dried at a high speed in the same manner as in the prior art to obtain a finished product. In particular, a circulation / discharge path is provided between the fermentation drying tank and the cyclone, and hot air is circulated and supplied until the temperature atmosphere in the drying tank almost reaches the predetermined high and low temperature ranges. It can be separated from this circulation path to 700-
Since the exhaust gas passes through a thermal storage deodorizing duct that spans a high temperature range of 850 ° C, heat is stored in the duct at almost the same temperature, so that the odor in the exhaust gas directly contacts this high temperature. It is deodorized and released into the atmosphere through the duct, so that the odor does not affect the surrounding environment.
