2. Description of the Related Art Conventionally, maturation of compost often depends on human intuition, and in most cases, compost is produced by judging from the experience of skilled workers. In recent years, various studies have been made on the maturation of compost, but it is a reality that there was no system for efficiently maturating compost.

SUMMARY OF THE INVENTION As described above, a compost ripening system which cannot be continuously managed in spite of the fact that it was costly and depended on manual labor is automatically collected and automatically operated as necessary. Therefore, a system for controlling the fermentation conditions of compost has been long-awaited.

[0004] The temperature inside the pile of compost piles rises because microorganisms aerobically decompose organic matter and the respiratory heat generated at that time accumulates without dissipating to the outside. This is partly due to the low thermal conductivity of the organic matter used as the compost material.
Since there is a risk of occurrence of ignition or the like due to the temperature rise, it is necessary to perform switching back in accordance with the temperature rise. Turning back is agitating the accumulated compost material.
And this switching must be repeated several times instead of once. However, the reality was that there was no system for instructing the timing of this switching, and it relied on human intuition.

[0005]
