The Working Theory of Twesix Tobacco Leaves Dryer The air source heat pump dehydrator for tobacco leaves is the latest generation of environmentally friendly and energy- saving products.The unitis based on the reverse Carnot cycle and the principle ofalr energyheat pump;it uses electrical energy todrive the system,uses high-temperature refrigerants circulation to do work,and absorbs energy fromthe alr by the heat exchanger.Direct output of high-temperature hot air,that is,1 electric energy input,and 3-5 heat can be obtained to dry tobacco leaves.Efficient and energy-saving and the unit system works without pollution and zero emissions,in line with environmental standards
