It is intended to provide microbial material (aged soil) that improves the soil so that organisms according to the providence of nature can grow.

  An aged soil generating apparatus for charging an organic waste mixed with a return material into a closed and openable and openable fermenter and fermenting the organic waste in a sealed state to generate an organic fertilizer is, for example, Patent Documents 1, 2 and the like.

  FIG. 2 is a diagram for explaining an example of an aged soil generating device disclosed in the patent document, and this aged soil generating device includes a roof 2 provided with an inclination on the upper part of a closed fermenter 1 and The bottom 4 of the roof 2 and along the side wall 3, and the air supply pipe 5 provided at the bottom of the fermenter 1.

  For example, in FIG. 2 (A), the fermenter 1 is configured such that the front door is movable up and down, and when the organic waste is carried in, the front door is opened and the organic waste 6 is charged. Subsequently, the front door is closed and the fermented organic waste 6 is put in a closed state with the fermenter 1 sealed, and then the front door is opened and fermented and decomposed to generate aged soil. However, the specific configuration is not limited to the illustrated example.

  The organic waste 6 charged in the fermenter 1 is propagated by the fermented bacteria contained in the organic waste by the air supplied through the air supply pipe 5 from the lower part of the fermenter 1, While the fermentation decomposition of the organic waste is promoted, the temperature rises and the water contained in the organic waste 6 evaporates.

  On the inner side of the upper part of the side wall 3 of the fermenter 1 (the side wall when the fermenter 1 is viewed from the surface), a basket 4 is provided, and the whole fermenter 1 is longitudinally (in the case of illustration, the front-rear direction with respect to the paper surface). ). And by the fermentation process of the organic waste 6 in the fermenter 1, water vapor | steam adheres to the inner side of the roof 2, and it is comprised so that this condensed water may flow through the inner side of the roof 2 to the eaves 4. The jar 4 is inclined downward toward the rear of the fermenter 1, and the dew condensation water flows rearward through the jar 4 and is drained to a tank 13 provided outside the fermenter 1. Condensed water adhering to the roof 2 is surplus water that delays the fermentation process, and contains a large amount of impurities, so draining the condensed water out of the fermenter 1 generates a high-quality aged soil. be able to.

  In the case of the illustrated example, a plurality of air supply pipes 5 are extended on the bottom wall of the fermenter 1 over the longitudinal direction of the fermenter 1. Each air supply pipe 5 is provided with a plurality of holes in the lower part, and the air sent downward from the holes collides with the bottom surface and flows upward, and is sent into the fermenter 1. Thereby, the fermentation process of the organic waste 6 is accelerated | stimulated. In addition, the air supply pipe 5 is covered with a cover member capable of supplying air so as not to be embedded with organic waste.

  As shown in FIG. 2B, the fermenter 1 has a rear wall 3 ′ (in FIG. 2, 3 is a side wall when the fermenter 1 is viewed from the front, 3 ′ is a side view of the fermenter 1 from the side. The intake pipe 7 passing through the air supply pipe 8 and the air supply pipe 8 connected to each of the air supply pipes 5 described above, the intake pipe 7 and the air supply pipe 8 being a passage tank. 9, a suction unit 10 is provided in the air supply pipe 8. By driving the suction unit 10, air is sent from each air supply pipe 5 into the fermenter 1 through the air supply pipe 8, and further, the air sent into the fermenter 1 is sent through the intake pipe 7 and the passage tank 9. Although it is sent to the air pipe 8 and circulated, outside air (oxygen) is supplied from the air supply blower 11 into the air supply pipe 8 of this air circulation circuit, and the fermenter 1 has an aerobic atmosphere rich in oxygen. Aged soil that is retained and contains aerobic bacteria is produced.

  A filter 9 a is provided in the passage tank 9, and a collection tank 12 is provided below the passage tank 9. The air taken in from the fermenter 1 through the intake pipe 7 passes through the filter 9 a in the passage tank 9, so that the water contained in the air is separated and collected in the collection tank 12. The recovered water recovered in the recovery tank 12 contains a large amount of effective bacterial cells, and can be effectively used as liquid fertilizer, inoculum (reverting agent) and the like.

  However, in the aged soil generating apparatus described in the above-mentioned patent document, since the air fed into the fermenter 1 is unbalanced depending on the location, the fermentation process is not performed uniformly, and therefore, in the fermenter during the fermentation process. These organic wastes were once carried out of the fermenter and stirred, and then returned to the fermenter 1 to perform fermentation treatment. Moreover, since outside air (oxygen) is supplied to the circulating air supplied into the fermenter 1 through the blower 11, aged soil with many aerobic bacteria and few anaerobic bacteria is generated, and plants that prefer anaerobic bacteria. It was soil with low resistance to diseases.

It is a principal part block diagram for demonstrating one Example of the matured soil production | generation apparatus used for implementation of this invention. It is a figure for demonstrating an example of the conventional matured soil production | generation apparatus.

  FIG. 1 is a schematic configuration diagram of a main part for explaining an embodiment of an aged soil generating apparatus according to the present invention. The basic configuration of a fermenter 1 is basically the same as that of the conventional fermenter 1 shown in FIG. Although the same, it does not have the air supply blower 11 shown in FIG. 2, and the air flow rate measuring device 8a for detecting the total amount of circulating air supplied to the fermenter 1 and the air supply of each air supply pipe 5 It differs in having the air flow rate adjusting devices 5a to 5e at the mouth. In addition, in FIG. 1, FIG. 1 (A) has shown the bottom part of the fermenter 1 planarly, FIG. 1 (B) is the back side exterior of the fermenter 1 like FIG. 2 (B). The state is shown three-dimensionally.

  In the present invention, as shown in FIG. 1 (B), since it does not have an air supply blower for supplying external air that is required in the prior art, in other words, outside air is circulated in the air circulating in the fermenter 1. Since it is not injected, oxygen is sufficiently contained in the circulating air at the beginning of the fermentation process.Therefore, aerobic bacteria propagate in the early stage of the fermentation, but the oxygen in the circulating air decreases as the fermentation process proceeds. The growth of aerobic bacteria is reduced and the growth of anaerobic bacteria is increased. As a result, aged soil in which aerobic bacteria and anaerobic bacteria coexist can be generated.

  Further, in the present invention, as shown in FIG. 1A, a plurality of air supply pipes 5 are disposed under the floor of the fermenter 1 as in the prior art, but these air supply pipes 5 are substantially equal. Arranged in parallel at intervals, the air supply ports of the air supply pipes 5 have air flow rate adjusting devices 5a to 5e. In the fermentation process, the opening degree of each of the air flow rate adjusting devices 5a to 5e is adjusted so that the air flow rates flowing through the air supply pipes 5 are substantially equal. Therefore, the circulating air spreads and circulates in the fermenter 1 substantially uniformly, and the bacteria are not concentrated in a part of the fermenter 1. Therefore, as in the prior art, the fermentation is performed during the fermentation process. There is no trouble of taking out the fermentation waste from the tank and stirring it, and the fermentation treatment can be carried out effectively.

  In the above description, it is assumed that each air supply pipe 5 has a flow sensor and the air flow rate adjusting device is automatically adjusted so that the flow rate detected by each flow sensor becomes equal. Actually, it is preferable from the viewpoint of production and maintenance of the apparatus that an operator adjusts while watching the situation.

  In FIG. 1, 8a is a flow meter for measuring the total amount of air circulating in the fermenter 1, and the operator sees the total amount of air flowing through the fermenter 1 from the flow meter 8a and flows it to each air supply pipe 5. The air flow rate is calculated to adjust the valve opening of each air flow rate adjusting device. For example, assuming that the air flow rate of the flow meter 8a is 100 l / s, the worker reads the indicated value of the flow meter 8 and adjusts the valve opening of each air supply pipe to 20 l / s.
