For realizing above-mentioned task, the technical solution of the utility model is: a kind of microwave-heating drier of adjustable power, at least two microwave raddiating circuit unit are installed in the drying machine, each microwave raddiating circuit unit is by a contactor, a high-tension transformer and one group of corresponding three magnetron constitute, three input coils of high-tension transformer and the corresponding connection of three outputs of contactor, above-mentioned three magnetrons of corresponding connection on three output windings of high-tension transformer, in each microwave raddiating circuit unit, has the power controller circuit that is connected with intermittent power supply on the solenoid of contactor of one road microwave raddiating circuit unit at least.
Each power of organizing magnetron equates.
The power controller circuit is made of the auxiliary reclay that square wave generation circuit and output thereof connect, and the contact of auxiliary reclay is serially connected on the power supply line of solenoid of contactor, and the dutycycle of square wave generation circuit is adjustable continuously.
The square-wave cycle of square wave generation circuit is at 20-30 between second.
Each is organized magnetron and evenly distributes in hothouse, and each magnetron of respectively organizing magnetron is in staggered distribution each other.
Because in each microwave raddiating circuit unit, has the power regulating switch circuit that is connected with intermittent power supply on the solenoid of contactor of one road microwave raddiating circuit unit at least, can effectively improve the reasonable coupling between microwave output power and load, improve the dry quality of energy utilization ratio and (heating); Be convenient to the control of realization simultaneously, the reasonable operation that is beneficial to process different types of material and under different disposal amount situation, makes microwave (heating) drying machine to (heating) dry general power.
