A method such as that described in Publication No. 68348 has been proposed, and in this method, after a large amount of persimmons to be treated to remove astringency are accumulated in a place configured to allow the removal of astringency, the entire surface of the persimmons is
The astringent removal chamber is kept airtight with curtains, etc. After that, carbon dioxide gas is continuously injected from the bottom of the astringent removal chamber to create a carbon dioxide layer, and the carbon dioxide layer is gradually increased (by continuing to inject carbon dioxide gas, ), and due to the difference in specific gravity with the air, the air in the deastringent chamber is exhausted with a layer of carbon dioxide gas, and the inside of the deastringent chamber is replaced with carbon dioxide gas, in a highly concentrated (almost 100%) carbon dioxide atmosphere.
The astringency is removed by holding astringent persimmons for the required time (there is no circulation of carbon dioxide gas in the astringent removal chamber).

2...Cover the top surface and, if necessary, the door side end surface,
Then, by operating the circulation fan 9 of the circulation path 6, the carbon dioxide gas-containing air, or the carbon dioxide gas-containing air containing an alcohol component as necessary, is supplied to the supply port 7.
It is supplied into the sealed chamber 1 from. The main air flow A formed by the carbon dioxide gas-containing air supplied into the sealed chamber 1 is caused by the main air flow A on the ceiling side by the blocking sheet 20, the rectifying means 16, and the suction action of the exhaust ducts 15, 15. The airflow is divided into sub-airflows B, B, etc. in a direction almost perpendicular to the airflow A, and the exhaust duct 1
5, 15, passes through the circulation path 6 again, increases the carbon dioxide content, and then enters the sealed chamber 1 from the supply port 7.
The astringent persimmons are then supplied to the persimmons and used to remove astringency from the astringent persimmons through the same route as mentioned above. In this case, since the carbon dioxide content of the carbon dioxide gas-containing air increases with circulation, the excess air is discharged from the relief valve 25, for example, until approximately 80% to 90% of the excess air is finally usable. Moreover, when an alcohol component is included, the alcohol content is 2 to 3%.

(See Figure 5). In this case, the supply port 7 may be extended into a supply duct 7', and a supply hole may be formed in the indoor side surface of the supply duct 7'.

There is no problem even if the air flows into the cargo boxes 2, 2, . Of course, if the rectifying means 16 is applied to both the supply side and exhaust side duct sections, it goes without saying that the rectification effect will be further improved.

As explained above, according to the astringency removal method and its device of the present invention, the atmosphere in the astringency removal chamber is made into carbon dioxide gas-containing air (alcohol component is added as necessary), and the atmospheric air is circulated. In addition, a rectifying means is used to flow the atmospheric air so that each persimmon that is to be de-astringent is evenly exposed to the large amount of atmospheric air.By rectifying the flow in this way, Therefore, the amount of carbon dioxide consumed (low concentration) is small, and running costs can be reduced.
イ） 炭酸ガスの濃度が極く低い初期（時間の経

なる。b) Since the air in the astringent removal chamber can be circulated from the initial stage when the concentration of carbon dioxide gas is extremely low (the CO 2 concentration increases as time passes), the astringent removal time is shortened.
ハ） 炭酸ガスと空気との混合ガスを循環使用す
