ことによりかびの育成条件を押えると共に、大気圧と略
同じレベルにすることで高真空を維持する容器は不要と
なり、装置を小型且つ簡易にできる。Furthermore, the air in the storage room is sucked in, and the floating mold components, moisture, and oxygen are discharged from the storage room, thereby eliminating a mold generation source. By keeping the growth conditions at the same level as the atmospheric pressure, a container for maintaining a high vacuum is not required, and the apparatus can be made compact and simple.
更に、第１、第２の開閉弁を用いることで、真空ポン
プは１個ですみ、装置の小型化が図れる。Further, by using the first and second on-off valves, only one vacuum pump is required, and the size of the apparatus can be reduced.
