2. Principle of Simultaneous heating of MW and NIR



3. Electric Components of MW and NIR Drying PlantMW Wavelength: 1mm ~ 1m (300MHz ~300GHz)NIR Wavelength: 0.75 ~ 3



4. Advantages of MW-NIR Simultaneous using MW and NIR is world-first proven by Korea Institute of Patent Information Supreme Energy Efficiency across the world. Agitators in the Multi-screws guarantee deep penetration of Microwave and Near Infrared Rays Using only Electricity, not Fossil Fuels Reduction of processing cost through highly efficient energy use Destroys 100% of pathogens (Momentary Reflective Heat amounts to 150~900) Integrates easily with all dewatering machinery Reduction in emissions and foul odors Easy to maintain with simplified facility with the use of PLC (Programmable Logic Control) Immediate warm up and cool down -no waiting time Multiple-phase integrated installations, small sites possible and scalable depending on volume



5. Mechanism of MW-NIR

Combination of Microwave- NIR(Near Infrared Rays) makes uniform heating and hard-to-dry object possibleSaves energy because not the atmosphere but the object itself is heated i.e., Direct heating, not heat conduction Achieved the top efficiency of heating amounting to 80% aboveSterilization of micro-organism by destroying and evaporating internal water by MW-NIRReliable with an intelligent service and maintenance
