         [0043]    The working process of the efficiency enhancement field induction based electromagnetic wave energy conducting equipment of the utility model is illustrated below with examples. Bottled water is taken as the object to be irradiated, and the area close to the main emission source on each conveyor belt is called an irradiation area. The specific working process is as follows: 
         [0044]    1. According to the size of the bottle to be irradiated, the channel width, the rotational speed of the conveyor belt, the number of bottles to be irradiated each time, the irradiation time, the stop delay time of the conveyor belt and other parameters are set; the channel width is set through the PLC; upon the setting is completed, the PLC sends a control signal to the second stepping motor, and then the second stepping motor rotates to drive a movable guardrail B to move so as to adjust the horizontal distance between the movable guardrail B and a fixed guardrail A. 
         [0045]    2. The conveyor belt is started, and at this time, a first limit rod retracts back, and a second limit rod stretches out; bottles to be irradiated are placed on the conveyor belt and driven forward by the conveyor belt. 
         [0046]    3. The infrared induction counter installed at the front of the conveyor belt starts counting. When the number of bottles passing reaches a set value, the first limit rod stretches out under the action of the first stepping motor to prevent following bottles from entering the irradiation area; the conveyor belt conducts delayed working for a certain time after the first limit rod stretches out, so as to ensure that the bottles in the irradiation area are close to the main emission source to the greatest extent. 
         [0047]    4. After the delay time is up, the conveyor belt stops working, and the irradiation timing begins; after the timing begins, the remaining time is shown on the front panel, and the LED progress lamp is on from low to high. 
         [0048]    5. After the irradiation is completed, the first and second limit rods retract simultaneously; the conveyor belt is started to transport out the bottles that have already been irradiated and transport in the bottles to be irradiated at the same time. Meanwhile, the infrared induction counter starts counting. 
         [0049]    6. When the quantity counted by the infrared induction counter reaches a set quantity, the first and second limit rods stretch out simultaneously, and the conveyor belt delays stopping to transport out the bottles that have already been irradiated and ensure that the bottles to be irradiated are close to the second limit rod to the greatest extent; for irradiated objects which have special requirements, such as brittle articles, the working time of the conveyor belt can be set to make it stop working immediately after it transports out irradiated objects, and the further processing can&#39;t be continued before articles are removed manually. 
         [0050]    7. During the subsequent work, repeat Steps 5 and 6 around and around till completing the whole processing course. 
         [0051]    8. After the irradiation of the last batch is complete, the first and second limit rods retract simultaneously; the conveyor belt rotates until all bottles are transported out, and then it can be shut down. 
         [0052]    It&#39;s important to note that in the above embodiments and drawings, each set of equipment has three main emission sources. Two conveyor belts are set respectively on both sides of every emission source, and there are six conveyor belts in total; each conveyor belt can work independently so that different articles can be processed or different irradiation time can be set as needed.
