Microwave Belt Type Drying and Sterilization equipmentWDG series microwave belt drying machine is a new style drying and sterilizing equipment researched and manufactured by our company. WDG1 is single layer belt type and WDG3 is three layers belt type. Working principle Use microwave produced by microwave generator to carry out heating material selectively and active water molecule in material or menstruum that can receive energy and makes it to heat and evaporate to the purpose of drying material and sterilization.
main usage:This equipment can be used in many fields, such as foodstuff, pharmaceutical, chemical industry, building material, latex, during the process of drying processing technic.
Operating principal:This microwave source adopts continuous microwave magnetron as its microwave oscillation source. The continuous magnetron is a kind of cross-field microwave radio tube, the direct current field and the stationary magnetic field are vertical. The anode of the magnetron is a complex system of resonance. The anode block consists of many little resonant cavity. Between them there is inductance coupling, so the anode block is the crossover network of microwave. The electron eradiated from the cathode of the magnetron will firstly be affected by the direct current field and curl like an angle. While the electrons are moving from the cathode to the anode, the contrail of their movement is like a swing vibration. Under the condition of synchronism between high frequency field and electron cloud, the electron contrail will rise toward the anode direction and form electron spoke. Among the spoke, while the electrons are carrying through synchronistically, they will change the potential energy into high frequency energy and increase the high frequency breadth. After the magnetron is started, the direct current which is instored in the resonance cavity will be changed into super-high frequency energy, finally, microwave source of enough power will exported through wave-guide.
Characteristics 1. Quick heating speed, good uniformity; 2. Energy saving, high effective; 3. Easy to control, flexible and convenient operation 4. Without powder dust pollution, easy to clean; 5. High recovery of material; Application Suitable for drying and sterilizing powder, granule, flake, Strip, cream. Etc material in pharmaceutical, chemical and foodstuff industry. Safety Before delivery, each machine should be tested strictly and the leakage amount of microwave is lower than the requirement of GB The Main Technical Parametersis for reference. We also produce and design product as per customers' requirements.
