呼称、脱湿乾燥機の発生露点の‐40℃~‐30℃では 露点‐70℃の乾燥機と比較して 3000倍乾燥(真空度)速度が遅いです。さらに50年前の乾燥HOPPERの構造内でのchipの変流を加えると、乾燥時間は4時間ではなくて3000*4=12000時間 /2時間が必要。ハニカムローターで低露点を出すには拡散理論をはじめ計算能力が必要ですが、外気への吸着筒の漏れを少し減らして-40℃出たとはしゃいでいる文科系は日本の恥です。 脱湿乾燥機の機能は通常の熱風乾燥機より劣ると考えるが、まともな技術を持つ会社は恥ずかしくて機器の名前を加湿乾燥機と変えるか、遠い他国の安い乾燥機に変えると考えられます。
The dehumidifying dryer has a dew point of -40°C to -30°C, and compared to a dryer with a dew point of -70°C, the drying (vacuum degree) speed is 3000 times slower. If you add in the current change of the chips in the drying HOPPER structure from 50 years ago, the drying time is not 4 hours but 3000 * 4 = 12000 hours / 2 hours. Achieving a low dew point with a honeycomb rotor requires calculation skills, including diffusion theory, but liberal arts students are a disgrace to Japan for being so excited that they achieved -40 degrees Celsius by slightly reducing the leakage of the adsorption cylinder to the outside air. I think the functionality of a dehumidifying dryer is inferior to a normal hot air dryer, but I think a company with decent technology would be embarrassed and change the name of the device to a humidifying dryer, or replace it with a cheaper dryer from a faraway country.
