再生する貯蔵庫内雰囲気調整方法に関する。Detailed Description of the Invention [Industrial Application Field] The present invention supplies atmospheric gas in a storage to a carbon dioxide adsorption device filled with activated carbon, and removes the atmospheric gas by adsorption and removal of carbon dioxide by the activated carbon. The content of carbon dioxide in the carbon dioxide adsorption device is adjusted, and the adjusted atmospheric gas from the carbon dioxide adsorption device is returned to the storage, and when the carbon dioxide adsorption capacity of the carbon dioxide adsorption device has decreased, the carbon dioxide adsorption device The present invention relates to a method for adjusting the atmosphere in a storage warehouse, in which the activated carbon is regenerated by stopping the supply of the atmospheric gas to the carbon dioxide adsorption device and circulating air into the carbon dioxide adsorption device.
従来の上記の貯蔵庫内雰囲気調整方法は、炭酸ガス吸着
装置に対する再生工程完了後、すぐに雰囲気ガスの供給
を開始して循環させていた。In the above-described conventional method for adjusting the atmosphere in a storage, the supply of atmospheric gas is started and circulated immediately after the regeneration process for the carbon dioxide adsorption device is completed.
しかし、再生工程完了時には、炭酸ガス吸着装置内に、

Since there is still air to be circulated for activated carbon regeneration, the residual air in the carbon dioxide adsorption device is introduced into the storage by circulating the atmospheric gas, thereby reducing the amount of oxygen contained in the atmospheric gas in the storage. If the amount increases or fluctuates greatly, there is a risk that the stored contents will deteriorate due to reaction with oxygen and will be difficult to store for a long period of time.
本発明の目的は、炭酸ガス吸着装置内の残存空気が貯蔵
庫内に入りに（くする点にある。An object of the present invention is to allow residual air in the carbon dioxide adsorption device to enter the storage.

、次の通りである。The characteristic means of the storage atmosphere adjustment method of the present invention is that after the regeneration process for the carbon dioxide adsorption device is completed, and before starting the supply of atmospheric gas and circulating it, residual air in the carbon dioxide adsorption device is removed under reduced pressure. In particular, its functions and effects are as follows.

合を防止できる。In other words, after the regeneration process is completed, the air remaining in the carbon dioxide adsorption device is removed under reduced pressure by starting the supply of atmospheric gas and circulating it, creating a controlled atmosphere with an adjusted carbon dioxide content. Only the gas is returned to the storage, and it is possible to prevent the inconvenience that the amount of oxygen contained in the atmospheric gas increases or fluctuates due to the intrusion of air into the storage.

を構成しである。As shown in the diagram, fresh foods such as vegetables, fruits, fish, meat, raw noodles, grains, flowers, microorganisms, etc. are stored at a constant temperature so that the content of nitrogen, oxygen, and carbon dioxide gas is maintained at appropriate levels. By adjusting the storage atmosphere, we have installed a storage (1) that can maintain freshness for a long period of time. The storage device is constructed by providing a carbon dioxide adsorption device (3) that adjusts and maintains the content of carbon dioxide (C(h)) in the atmospheric gas at a constant level by adsorbing and removing carbon dioxide (C(h)) on activated carbon (2). .

It can promote the respiratory inhibitory effect and at the same time suppress the activation of bacteria.

圧除去する。When the supply of atmospheric gas is started immediately after the regeneration process for the carbon dioxide adsorption device (3) is completed, the adjusted atmospheric gas returned to the storage (1) contains the inside of the carbon dioxide adsorption device (3). As a result of the air remaining in the space being mixed in, the atmosphere inside the refrigerator contained 93% nitrogen (N), 5% oxygen (0□), and 2% carbon dioxide (CO□), which was significantly different from the initial adjustment. In order to achieve a high carbon dioxide gas adsorption rate, after the regeneration process for the carbon dioxide adsorption device (3) is completed, the residual air in the carbon dioxide adsorption device (3) is removed under reduced pressure before the supply of atmospheric gas is started and circulated.
