According to a tenth aspect of the present invention, a plurality of processing tanks are provided, and one traveling stirrer is moved between the processing tanks to perform stirring. 8
Or it is an organic waste compost manufacturing apparatus according to a ninth invention.

Since commercially available inoculum is not always in an active state, fermentation often takes a long time even when mixed with organic waste, and a long period of time is required for composting. However, in the case of the method according to the present invention, the organic waste containing actinomycetes in the active state after acclimation has a pH of 6.5 to 9.5.
Since the water content is 45 to 60% and the product temperature is 20 to 70 ° C., and the mixing ratio with the treated material is high, the organic waste to be treated starts fermentation immediately after mixing. For this reason, fermentation does not take much time, and low-temperature (including below freezing) organic waste in winter can be treated in a short period of time.

The processing tank may be provided in a straight line direction or in a U-shape. In addition, it can be provided in an endless circular, oval, or elliptical shape. The track may have a protruding rail shape or a groove shape, and its structure is not limited as long as it can guide the traveling stirrer. The number and arrangement in the case of providing a plurality of treatment tanks are not particularly limited, and are appropriately set in accordance with the scale and capacity for treating organic waste. Also,
The processing tanks may be arranged side by side in the horizontal direction, or may be provided in multiple stages vertically, and they may be used in combination.

The main stirrer of the traveling stirrer mainly stirs and moves the organic waste. When the organic waste is moved, it is rotated in a direction in which the organic waste is scraped up, so that the organic waste is deposited at a high level. Can be done. Further, by rotating in a direction in which the organic waste is scraped up toward the opposite side to the traveling direction, organic waste can be deposited at a low level. In this way, the organic waste can be leveled substantially flat. The type of the conveyor used in the take-out device, the mixing and crushing device, the input device, the discharge device, and the like is not particularly limited. For example, a belt conveyor or the like can be used in addition to the screw conveyor.

The main stirring member is for stirring the organic waste normally deposited at a height of 40 to 80 cm.
An extremely narrow gap is provided between the bottom of the processing tank and the upper surface of the processing tank so that most of the organic waste in the processing tank can be conveyed while scraping by repeating the stirring.
The tip of the sub-stirring member of the sub-stirrer is provided with a gap of, for example, about 20 to 40 cm from the upper surface of the bottom so that a part of the upper portion of the deposited organic waste can be stirred.

The conventional traveling stirrer only has the same stirrer as the main stirrer described above, and the stirring and transport are performed for all the accumulated organic waste. On the other hand, since the traveling stirrer according to the present invention includes the sub-stirrer, it can stir and transport a part of the organic waste on the upper side. Therefore, for example, in the case of an organic waste which emits a bad smell such as blood or hair generated in a slaughterhouse, a spraying device is used to spray actinomycetes on the organic waste in an active state, and further a sub-stirrer Thus, by transporting and accumulating the organic waste in which the actinomycetes are in an active state, it is possible to treat the organic waste in a short period of time without releasing a bad odor.

The smaller the organic waste and the larger the surface area per unit weight, the faster the fermentation and the better the processing efficiency. For this reason, garbage, bark, slaughterhouse clots, etc. can be treated in a short period of time by crushing small (eg, about 1 to 3 mm in external dimensions) with a crushing device such as a mincing machine in the pretreatment.

(Operation) The compost production apparatus according to the present invention operates as follows. As in the compost production apparatuses according to the seventh, ninth and tenth aspects, those in which the traveling stirrer is provided with a blower for blowing air to the organic waste in the treatment tank are included in the organic waste during fermentation. Since the evaporation of water can be promoted, the water content of the organic waste can be reduced in a short time. This speeds up the activation of actinomycetes and consequently makes it possible to compost organic waste in a short period of time.

In the case of a compost manufacturing apparatus according to the eighth, ninth and tenth aspects, which includes a take-out device, a mixing and crushing device, and a charging device, first, the mixing and crushing device (mixing and crushing device) is used. Or the mixed and pulverized) organic waste is charged into a treatment tank by a charging device in a required amount (for example, 1 to 2 tons), and inoculated with an inoculum including actinomycetes (for example, 20%, 200 kg in the case of 1 ton). I do. Then, the mixture is stirred by the main stirrer of the traveling stirrer and deposited at a required height. In this state, the organic waste starts fermenting.

On the next day, the organic waste from the previous day is moved to the discharge side to be deposited, and a place for charging the organic waste is secured. Here, a required amount (for example, 1 ton) of the organic waste newly mixed and crushed in the same manner as above is charged, and the inoculum is inoculated (for example, 20 tons).
0 kg). Stir with the main stirrer of the traveling stirrer and deposit at the required height. At this point, the first time of the organic waste charged is not yet active in the actinic fungi. Then, the same operation as described above is performed for about 3 to 5 days until the amount of the practical seed bacteria described below becomes an amount effective for treating the organic waste.

Several days after the inoculation of the inoculum, the actinomycetes in the organic waste which was first introduced are activated, and the number of actinomycetes in the organic waste is 2 × 10 ⁵ / g to 1 × 10 ^10. When the amount reaches about / g, the mixture is scraped by the main stirrer onto the organic waste charged in the second, third,.... And
The traveling stirrer is moved to the inlet side of the treatment tank, and a part (for example, 1/2) of the organic waste containing the actinomycetes in the active state is moved.
Is moved to the inlet side of the treatment tank through the organic waste charged in the second, third,... While being stirred by the auxiliary stirrer of the traveling stirrer. This organic waste in which actinomycetes are in an active state is defined as a practical seed fungus.

A part of the practical seed bacteria is taken out of the treatment tank by a take-out device, and is mixed and crushed by a newly crushed organic waste and a mixing and crushing device. The organic waste mixed and crushed with the practical seed bacteria is charged into the treatment tank by the charging device. At this time, if there is any practical seed bacteria remaining in the treatment tank without being taken out of the treatment tank by the take-out device, the mixed and crushed organic waste is thrown into it by the throwing device. Then, the traveling stirrer is reciprocated within the range where the organic waste is charged, and is stirred by the main stirrer to further mix the organic waste and the practical seed bacteria. At this time, the temperature of the product reaches 40 to 60 ° C. from, for example, about 20 ° C. after several hours. This is moved to the discharge side of the processing tank by the main stirrer and deposited. After that, return the practical seed bacteria to the entrance side,
Take-out, mixing and crushing, charging, and stirring and conveying are repeated, and the organic waste is sequentially composted while moving to the discharge side of the treatment tank.

As in the case of the compost manufacturing apparatus according to the tenth aspect of the present invention, a plurality of processing tanks are provided, and one traveling stirrer is moved between the processing tanks to perform stirring. By taking it widely, it becomes possible to treat a large amount of organic waste. In addition, since only one traveling stirrer is required, maintenance costs such as equipment costs and electricity costs can be reduced.

The operation of the compost manufacturing apparatus A will be described with reference to FIGS. In the following description, the movement of animal waste, which is organic waste, in the treatment tank 1 is performed once a day. (1) A required amount of raw manure F0 is charged from the charging device 6 to the inlet side of the processing tank 1. Since the livestock dung F0 is crushed into mince by the mixing and crushing device 5 and the cells are destroyed, nutrients are obtained, and fermentation by actinomycetes is efficiently performed.
The livestock dung F0 is inoculated with an appropriate amount of a progenitor fungus prepared by cultivating actinomycetes in advance by using oil cake or the like as a bacterial bed, and stirring once or several times daily by the main stirrer 22 of the traveling stirrer 2 to remove actinomycetes. Culture (see FIG. 10).

(2) The traveling stirrer 2 is driven slowly while rotating the main stirring member 222 of the main stirrer 22 in the counterclockwise direction without driving the auxiliary stirrer 23. As a result, the animal dung F0 moves to the discharge side of the processing tank 1 by a predetermined distance, and rises in a layer having a gentle slope on the inlet side of the processing tank 1 (see FIG. 11). In addition, the traveling stirrer 2
Is provided with a fan 28, so that evaporation of water contained in the animal dung during fermentation can be promoted, and the water content of the animal dung can be reduced in a short period of time. by this,
Activation of actinomycetes is accelerated.

(3) The next raw livestock dung F0 is fed from the feeding device 6 to the vacant portion after the fermented livestock dung F1 has moved (a part of the livestock dung F1 has a thin layer at the bottom). An appropriate amount of the seed strain produced by culturing the actinomycetes is injected and inoculated, and the main stirrer 22 of the traveling stirrer 2 is stirred once or several times a day to culture the actinomycetes.

(4) In this way, the animal dung F0 is added in order, and when the animal dung F1 becomes an appropriate amount, the traveling stirrer 2 is appropriately moved from the discharge side to the inlet side, and
Is not driven, and the main stirring member 222 of the main stirrer 22 is rotated counterclockwise in the figure. Thus, the animal dung F1 is raised to form a large number of mountain parts (see FIG. 12). In each mountain, air is efficiently supplied from the slope,
