Drying of materials is a very important part of many production processes. The choice of drying method and drying equipment will have a great impact on the yield, quality of the target product, and human, material and energy consumption in the drying process. As a new drying method, microwave drying is based on the principle of selective absorption of microwaves by materials, which rapidly heats the water and finally achieves the purpose of evaporation and removal.

Advantages of rotary continuous microwave drying equipment:
Rotary Microwave Drying Equipment
Rotary continuous microwave drying device, in the drying process, the material rotates continuously with the main body of the container; its surface is constantly updated. The particle or powder of the material has the opportunity to be heated by microwave on its surface, avoiding the accumulation of water vapor inside the material, thus ensuring the uniformity of the quality of the dried materials. At the same time, during the rotation process, the material accumulation becomes loose, and the gas and the material can be in full contact, which is beneficial to increase the diffusion of water vapor and accelerate the drying rate of the microwave; especially for the heat-sensitive substance, due to the continuous renewal of the surface of the material, the airflow and the material in the reverse contact process, the airflow takes away part of the water vapor and heat, thereby avoiding the occurrence of overheating caused by the accumulation of water vapor and heat inside the material. Guarantee the quality of dry materials; for materials which are easily oxidized and decomposed by heat, nitrogen gas, argon gas and other inert gases may be introduced to provide gas protection to the dry materials, thereby reducing the possibility of side reactions of the materials; since the drying process is in a relatively closed container body At the same time, with the protection of high-speed airflow, the water vapor generated during the drying process is not easy to condense back to the drop; for materials with higher water content, since the evaporated water vapor is only limited to the inside of the container body, the short circuit caused by the moisture inside the microwave device is avoided, the service life of the drying device is prolonged, and the safety of the operation is improved; for materials that generate harmful gases during the drying process, the reverse gas flow can remove harmful gases from the drying system in time, reducing the occurrence of side reactions; the treatment amount of the dry material can be improved by adjusting the inclination angle of the container body, the rotation speed, and the ventilation amount of the drying gas, without causing overheating inside the material; the relatively closed container body is beneficial to waste gas recovery and reduces environmental pollution; the whole drying process is carried out in a continuous state, the pretreatment of dry materials is low, the degree of automation is high, and the labor consumption is small.
