Number, after being opened due to valve plate 42, temperature can need to increase power and keep constant temperature lower than the lower limit temperature of setting；Hereafter, the second temperature
Degree sensor 21 continues to monitor, and when temperature is higher than the ceiling temperature of setting in liner 2, then controls heater 3 by controller 5
The second gear is operated in, in emergency circumstances, controller 5 turns off heater 3；
4) when the moisture drying in Chinese medicine, there is no steam generation or only a small amount of steam generation, second point of valve plate 426
Condensed water on lower surface is greater than the amount that condensation converges on second point of valve plate 426 due to instilling the amount of water storage component 43, and second
The total weight of valve plate 426 and water storage component 43 is divided to be gradually reduced, until no larger than first point of valve plate 425, valve plate 42 is whole again
Secondary overturning, referring to Fig. 3, to overturn counterclockwise, first point of valve plate 425 is downwardly turned over as a result, returns to initial position,
Controller 5 controls heater 3 and turns off, and waits next heating evaporation circulation.
