The cost of drying effectively improves the drying efficiency of agricultural product drying case.
3, the heating of hot-air and dehumidification work in drying box are converted using solenoid valve I and solenoid valve II, it is easy to operate, no
It needs to put into a large amount of manpower and materials, effectively improves the drying efficiency of agricultural product drying case.
4, the setting of air inlet pipe facilitates the supply of air in drying box, easy to operate, effectively improves agricultural product drying case
Drying efficiency.
5, the setting of throttle valve can be realized carries out current limliting to dry HAI Heated Air Intake amount, avoids dry hot-air random
It then enters in drying box, improves the service efficiency of hot-air in drying box, effectively improve the drying efficiency of agricultural product drying case.
