Research and Development of Hypoxia-Heat Pump Drying Technology
The hypoxia-heat pump drying technology can dry the air in a closed circulation system by using other gases such as carbon dioxide and nitrogen instead of conventional air.This drying method can improve the drying quality,save energy and raise dry efficiency.It is also an effective way to solve the drying problem of some materials sensitive to heat and oxygen.This technology has a wider application prospect.The research and development of hypoxia-heat pump drying technology were reviewed,including the characteristics of drying medium,the quality of dried products and its related devices.
