Comparing to conventional dryer, microwave dryer could fast and efficiently drive the waster form the center of cardboard to the surface under a short time.(1) Microwave works by sending electronic wave evenly excite the water molecule to reach uniformly heating result and powerful penetration.(2) For a multiple layers of cardboard with different density, microwave effectively dries all layers of paperboard to obtain a balanced drying result, also significantly reduce the drying time.(3) Combining with PLC automatic control and temperature sensor, microwave had better control drying process and drying result. There are some unique advantages like simple operation, less labor, easily installation and environmentally-friendly.
