2. Description of the Related Art For example, water-containing wastes (eg, waste foods with expired dates, leftover foods, vegetable scraps, fish roe, etc.) from households, commercial food processing plants, supermarkets, restaurants, etc., from livestock farmers. Since organic waste such as sludge and sludge generated at the terminal treatment plants of administrative bodies such as local public bodies cannot be incinerated as it is because of high water content, first dry it with a dryer and then incinerate it with an incinerator. Was there. Recently, a method has been proposed in which such an organic waste is subjected to a fermentation treatment and used as an organic fertilizer. In a conventional fermentation treatment apparatus, organic waste is put into a treatment tank having a single treatment chamber or a treatment tank having two treatment chambers to perform fermentation treatment by a batch method.

[0003]

With this batch method, organic waste having a high water content (water content of 85% for garbage is obtained).
In order to carry out fermentation treatment, the dry matter (sawdust etc.) must be added together to make the water content of the treated material 50% to 60%.
Fermentation process is performed after lowering the water content to about%. This is because when the water content is high, the action of microorganisms is bad. The amount of dry material to be added is 30 for the material to be processed.
% -40% dry material is required. And the input and removal of organic waste from the treatment tank is from 24 hours to 48 hours.

Next, a method of fermenting an organic waste by using this apparatus will be described. The fermentation treatment of the organic waste is performed by moving the organic waste in the first to fifth processing chambers 6 to 10 using the stirring bodies 22 to 26 of the rotating shafts 20 and 21. The transfer process of organic waste includes a transfer process and a post-transfer process. During the transfer process,
Both rotary shafts 20 and 21 are simultaneously rotated in the same direction (normal rotation) as shown by the arrow in FIG.
Are all rotated normally. Organic waste is agitator 22-2
By the normal rotation of 6, in other words, from the left side to the right side in FIG. 7A, the process chamber is transferred from the front process chamber to the rear process chamber.
During the post-delivery process, both rotary shafts 20 and 21 are shown in FIG. 7 (B).
At the same time, the stirring bodies 22 to 26 are all reversed as indicated by the arrow. Stirrers 22-26 for organic waste
7B, in other words, from the right side to the left side in FIG. 7B, in other words, the post-processing chamber is post-transferred (moved in the reverse direction) from the post-processing chamber. However, from the second processing chamber 7 to the first processing chamber 6
The post-delivery to is not performed due to the presence of the partition wall 5a. In the processing method of the present invention, both rotary shafts 20 and 21 are simultaneously rotated in the same direction and rotation in the opposite direction, that is, forward rotation and reverse rotation, to transfer and post-transfer (forward) the organic waste through the stirring members 22 to 26. And organic waste is second.
Rather than moving linearly from the treatment chamber 7 to the fifth treatment chamber 10, by incorporating a process of returning to the previous treatment chamber in the movement process, the stirring and movement time of the organic waste in the treatment chamber can be lengthened and fermentation can be performed. It is an organic fertilizer that can be matured, matured and dried. Organic waste is
From the second processing chamber 7 to the fifth processing chamber 10 until the processing is completed and exits from the fifth processing chamber 10 after being input to the first processing chamber 6.
Fermentation treatment is performed while repeating forward and backward movements up to. Here, the processing of the organic waste accompanying the operation of the rotary shafts 20 and 21 (stirring bodies 22 to 26) will be described. First, the process in the forward rotation process of the rotary shafts 20 and 21 will be described. When the rotating shafts 20 and 21 are rotating in the normal direction, the stirring bodies 22 to 26 rotate in the directions of the arrows in FIGS. Therefore, the organic waste in the first processing chamber 6 is crushed while being heated by the heater 18, and the water content is adjusted. The organic waste is reduced in amount by the treatment in the first treatment chamber 6 and is crushed into fine pieces. The organic waste in the first processing chamber 6 is overflowed by the amount of organic waste newly input from the input port 11 in an amount exceeding the volume in the first processing chamber 6, and the second processing is performed from the transfer opening 5a1. Transferred into the chamber 7. The organic waste in the second processing chamber 7 is crushed while being heated by the agitator 23, the water content is adjusted, the amount is further reduced as compared with the processing in the first processing chamber 6, and the organic waste is finely crushed and fermented. It is processed. At the same time, organic waste in the second processing chamber 7 is transferred little by little from the through hole 5b1 formed in the partition wall 5b by 攪拌体23 into the third process chamber 8. Also, the third to fifth processing chambers 8 to 10
Each while being heated also organic waste inner 攪拌体24
It is stirred at ~ 26, further reduced in volume while adjusting the water content, and subjected to fermentation treatment, and the organic waste in the third treatment chamber 8 is transferred from the through hole 5c1 provided in the partition wall 5c to the fourth treatment chamber 9 to the fourth treatment chamber 9.
The organic waste in the processing chamber 9 is transferred little by little from the through hole 5d1 provided in the partition wall 5d to the fifth processing chamber 10. Thus, at the time of normal rotation, the organic waste already stored in the first to fifth processing chambers 6 to 10
The organic waste that has been input or transferred from the adjacent chamber is agitated and processed. Next, the process in the reverse rotation process of the rotary shafts 20 and 21 will be described. Rotating shaft 20,2
1 is reversed, the agitators 22-26 are shown in FIG.
6 to 6 rotate in the direction opposite to the arrow direction. The organic waste in the first and second processing chambers 6 and 7 is crushed while being heated by the heater 18 as in the normal rotation,
The water content is adjusted and the weight is reduced. The organic waste that has been fermented in the second processing chamber 7 is not sent to the first processing chamber 6 later.
Further, the fermentation-treated organic wastes in the third to fifth processing chambers 8 to 10 are partially returned (post-sent) to the preceding processing chambers by reversing. That is,
The organic waste in the third processing chamber 8 is discharged from the through hole 5b1 to the second
The organic waste in the fourth processing chamber 9 is transferred from the through hole 5c1 to the third processing chamber 7 and the organic waste in the fifth processing chamber 10 is transferred through the through hole 5d1 in the same manner. To 4th
A small amount of each is sent to the processing chamber 9 later. Thus, in reverse rotation, in the first and second processing chambers 6 and 7, the organic waste inside is removed by heating the heater 18 and stirring the stirring members 22 and 23 as in the normal rotation. Weight loss and crushing are performed. However, in the second processing chamber 7,
The treatment is performed in a state where the organic waste sent back from the third treatment chamber 8 in the latter stage is added. Also, the third to fifth processing chambers 8
In Nos. 10 to 10, while agitating the organic waste, a part of the organic waste is returned to the former treatment chamber on one side, and the organic waste flowing from the latter treatment chamber is mixed on the other side. A specific example will be described. By heating the heater 18, the room temperature in the first to fifth treatment chambers 6 to 10 of the waste fermentation treatment tank 1 is increased to about 60 to 70.
Keep it at about ° C. First, for example, 10 t of organic waste is introduced into the first treatment chamber 6 of the waste fermentation treatment tank 1 through the inlet 11. Introduced organic matter waste, while being heated by the heater 18 in the first treatment chamber 6, disrupted by repeated reverse and forward rotation of 攪拌体22 to 24 hours after the addition, about one-third water Adjusted and reduced. After the lapse of 24 hours from the charging, when the same amount of the organic waste as above is again charged into the first processing chamber 6 from the charging port 11, the amount of the organic waste exceeding the processing volume in the first processing chamber 6 overflows. And is transferred into the second processing chamber 7 from the transfer opening 5a1 provided in the upper portion of the partition wall 5a. While being heated by the organic waste as well as the heater 18 of the organic waste also within the first process chamber 6 in the second processing chamber 7, it is crushed to a granular by repeated reverse and forward rotation of 攪拌体23,
The water content is adjusted, the amount is reduced, and the fermentation treatment with bacterial cells is performed. Organic waste in the second processing chamber 7 is transferred in portions to the third process chamber 8 from the through hole 5b1 by the forward rotation of 攪拌体22. While it is heated by the organic waste as well as the heater 18 in the third processing chamber organic waste also within the second processing chamber 7 in 8, by the repetition of reverse and normal rotation of 攪拌体24 of the rotary shaft 21, the moisture adjustment It is, is reduced, both the further fermentation process is achieved, is transferred little by little from the through hole 5c1 by the forward rotation of the 攪拌体24 to fourth processing chamber 9, through-hole 5 by reversing
It is sent to the third processing chamber 8 little by little from b1. For even fourth through organic waste fifth treatment chamber 9, by the repetition of reverse and normal rotation of 攪拌体24 of the rotary shaft 21,
Is moisture control, is reduced, fermentation can be transported further together is promoted becomes more finely divided or powdered, portionwise than the through hole 5c1 by the forward rotation of the 攪拌体24 to fourth processing chamber 9,
By the reverse rotation, the toner is sent from the through hole 5b1 to the third processing chamber 8 little by little. Organic wastes in the fermentation condition that the fine granular or powdered fifth treatment chamber 10 which have been processed is discharged from the discharge port 12 by the forward rotation of the 攪拌体24 of the rotary shaft 21. Twenty-four hours after the input, the discharge amount is reduced to 1/3 of the input amount, the water content is also about 25%, and the fermentation, ripening, and drying of the organic waste can be continuously performed, and the organic fertilizer is Production is now possible. Since this organic fertilizer contains bacteria, the bacteria act effectively in the soil when used, and become an effective fertilizer. The heated organic wastes in the second to fifth processing chambers 7 to 10 are stirred and moved by the rotation of the stirring members 23 to 26, and the fermentation of bacteria is promoted by the rotation of the stirring members 23 to 26. Since the work of long stirring and moving is continued, aging, complete ripening and drying can be effectively performed. In the above example, the fermentation treatment of the organic waste having a daily dose of 50 kg to 30 t could be continuously performed in a 24-day cycle. When the amount of the organic waste flowing into the third to fifth processing chambers 8 to 10 is larger than the amount of the organic waste flowing out, the overflow transfer opening 5b2 provided at the upper portion of the partition walls 5b, 5c, 5d. Transferred from 5c2, 5d2 to the adjacent processing chamber. The odor from the organic waste in each processing chamber 6-10 and the steam generated by heating are exhaust pipes 15a, 1
It is discharged to the exhaust port 16 through 5b and 15c.

In the above example, the second to fifth processing chambers 7 to 10 are fermentation processing chambers, but all the processing chambers including the first processing chamber 6 may be fermentation processing chambers. Although the rotating shaft used in FIG. 1 has two, it may have a single rotating shaft. Although five processing chambers are provided, the middle processing chambers of the second to fourth chambers may be added, and the number of chambers is not limited to the example.
