As one of the effective uses, there has been a culture soil for agricultural crops using raw garbage, human waste sludge, terminal sludge, and animal manure, which have been conventionally discarded as industrial waste.

[0003]

However, in a conventional culture apparatus used for producing a culture soil using garbage as a raw material, a completed culture soil is taken out of the culture apparatus every time the culture soil is produced. In this case, the raw material must be supplied every time the culture soil is manufactured, which not only requires a lot of work, but also the processing capacity itself of the culture device for manufacturing the culture soil is low and is not practical. There was a problem.

[0004] Further, when human waste sludge, terminal sludge, or animal manure is used as a raw material for the production of culture soil, a peculiar unpleasant odor is drifted around during the production of the culture soil, thereby causing the worker to have an unpleasant smell. This problem has harmed the working environment of the residents and worsened the living environment for residents who live near the manufacturing plant.

To conclude. Although not shown, the receiving portion 22 is connected to the upwardly connecting tube 7 of the first empty cylindrical tube 2.
And the structure is such that the mixture 12 fed from the second case conveyor 21 can be efficiently carried into the cylindrical tube 2.

On the other hand, the open downward connecting pipe 7 of the second cylindrical pipe 2 is inclined at the same angle as that of the first cylindrical pipe 3.
When the fourth to twentieth cylindrical pipes 2 are mounted on the upward connecting pipe 7 of the second cylindrical pipe 2, the same procedures as those of the first to third cylindrical pipes 2, 2, 2 described above are performed. The attachment is repeatedly performed to form the culture apparatus 1 having a structure in which the 20 tubular tubes 2 are connected efficiently using the installation space efficiently.
The downward connecting pipe 7 of the twentieth cylindrical pipe 2 serves as a final outlet for the culture soil 13 manufactured in the present embodiment, and therefore a final receiving box 26 is provided.

In the present embodiment, the number of the cylindrical tubes 2 is 20. In the present embodiment, the culturing apparatus 1 is formed by connecting 20 machines, but when the cultivation soil 13 finally produced has a water content of less than 18%. The number of the cylindrical tubes 2 to be installed is not particularly limited, as long as it is in a state suitable for the activity conditions of the yeast and there is a balance with the moving speed of the cylindrical tubes 2. In addition, each tube 2
The inclination angle at the time of installation is not particularly limited, and the setting of the inclination plays an auxiliary role in moving the mixture 12 in the case tube 3.

The cultivation soil 13 formed by the cultivation apparatus 1 as described above produces a cultivation soil 13 of high product value in which the activity of yeast mixed with a water content of less than 18% is active.

Using the cut-out conveyor 17, the chicken manure 32 is sent to the second case conveyor 21 while being subdivided. However, since the chicken dung 32 generates an unpleasant odor peculiar to manure in the vicinity, simply carrying out the drying step dissipates a stronger odor. The mixture 33 with the yeast is cultivated by the culture device 1
The mixture 33 is fed into the rotary drier 14 after passing through the culture apparatus 1 and dried until the water content becomes about 18%, which is desirable as a product. As a result, the mixture 33
Is dried slowly, so that a comfortable working environment can be constructed without causing unpleasant odor during production of the culture soil 34. The chicken dung 32 used as a raw material for the culture soil 34 was used.
It is also possible to use other animal manure, human waste sludge, or terminal sludge as an alternative raw material.
