炭酸ガス（Ｃｏ２）濃度が増加してくる。Due to the reaction of C+O+N -+0020N2, the exhaust gas becomes only carbon dioxide gas (Co2) and nitrogen (N2), which is sent to the cooler 15.
After cooling, it is circulated into the storage 1 through the discharge pipe 11. Regarding the gas composition in the storage 1, the concentration of oxygen (02) decreases and the concentration of carbon dioxide (Co2) increases.

will be introduced to. At the same time as the pulp 44 is closed, the valves 29 and 30 are opened and introduced into the adsorber 24 by the blower 28. Only ethylene and carbon dioxide (C02) are adsorbed by the adsorbent 38 and 37, and only nitrogen (N2) is discharged through the exhaust pipe. 2
7 and returned to storage 1. The adsorbers 24 and 25 alternately repeat adsorption and desorption functions, and either adsorber continuously adsorbs ethylene and carbon dioxide (Co2). Therefore, the carbon dioxide concentration in the storage 1 is maintained at the S level. On the other hand, the oxygen (O2) degree decreases as it is being used for combustion during that time and reaches the predetermined level of 5 degrees after 16 hours. The gas monitor 49 detects this and stops the carbon dioxide gas generator 8. Now the concentration of gas in storage 1 is at the predetermined gas concentration N2: 90%

Thereafter, when the carbon dioxide (Co2) generated by the respiration of fresh food stored in the storage room 1 exceeds a predetermined value of 6, the gas monitor 49 detects it and activates the carbon dioxide adsorption device 9 to absorb carbon dioxide to a predetermined level. Absorb until the value is reached.
