Characteristics of microwave drying

1. Fast drying speed and short drying time. Because of the special microwave heating method, the temperature of the material increases rapidly in a short time, and the bulk heating makes the temperature gradient consistent with the direction of water evaporation, which improves the drying driving force, resulting in a very short drying time, which can be reduced by about 50% or more It is beneficial to the low temperature drying of temperature sensitive materials such as medicine and fertilizer, so as to maintain the properties of materials. In addition to the thermal effect, microwave can also excite polar molecules to change their orientations continuously with its high-speed molecular oscillation, resulting in non thermal effect and accelerating the drying process The product is of high quality, the microwave heating temperature is uniform, the surface and the inside are consistent, and the moisture distribution is uniform Microwave is energy saving, environmental protection and pollution-free. The microwave source can be used immediately, the power is continuously adjustable, the reaction is easy to control, the energy utilization rate is high, the heat energy almost all acts on the material, neither waste nor pollute the environment.
