With the above configuration, organic waste generated in the agriculture and livestock industry, the food industry, the sludge center, and the like is introduced from the inlet 37 of the container 1 for treating organic waste. That is, by operating the air cylinder 41 to open the opening / closing lid 45 via the piston rod 43, organic waste is collected in the container 3 from the charging port 37.

The organic waste collected in the container 3 is mixed by driving the rotation motor 17 to rotate the rotor 9 and perform, for example, drainage as preliminary fermentation. In addition, water generated from the organic waste is drained to the outside through the drain port 23 through the opening 25. Coarse compost (returned compost) is used as a moisture adjusting material for moisture adjustment when mixed. Here, the C / N ratio is adjusted as an appropriate ratio simultaneously with the water adjustment.

In the container 3, primary fermentation is performed. That is, the concentration of carbon dioxide (CO ₂ ) is kept high, and the growth of composted microorganisms is promoted under anaerobic conditions. As the management of the primary fermentation state, for example, dehumidification is performed with the condensation 33 of the dehumidifier in order to maintain the concentration of carbon dioxide at 10 to 20% and the humidity at 70 to 90% under 5 to 10 days.

It can be touched with the air, and can be promoted to obtain good compost by being comminuted and preventing the compost temperature from rising too high. Then, at the time of this switching, a soil culture solution is sprayed to suppress odor, promote fermentation, and supply water.

Next, after the primary fermentation, the secondary fermentation is performed in the container 3 under anaerobic and aerobic mixed conditions. At this time, the damper 57 is opened and oxygen is supplied from the outside into the container 3 in a required amount. This secondary fermentation state management is performed, for example, under 14 to 30 days while maintaining the concentration of carbon dioxide at 0 to 2% and the humidity at 50 to 70%. In the case of this secondary fermentation, the cutback is performed at a rate of about four times / month, similarly to the primary fermentation.

Upon completion of the secondary fermentation, aging is performed under aerobic conditions. Also at this time, the damper 57 is opened as necessary, and a required amount of oxygen is supplied into the container 3. As for the management of the fermentation state of this ripening, for example, ripening is performed for 30 to 90 days while maintaining the concentration of carbon dioxide at 0 to 2% and the humidity at 50 to 70%. During this ripening,
Switching is performed about twice / month. In addition, since the water tends to be insufficient, the culture solution is sprayed.

When the maturation is completed, the air cylinder 47 is operated to open the opening / closing lid 51 via the piston rod 49 and take out the compost having a good smell and a good ripe quality without a bad smell from the discharge outlet 39 to the outside. Can be
