Description

technical field [0001] The invention relates to the technical field of drying machinery, in particular to a belt dryer combined with microwave and electromagnetic heat source convection. Background technique [0002] Convection drying refers to a drying method in which the heat transfer method is mainly convective heat transfer. There are many dryers of this type, such as belt dryers, airflow dryers, flash dryers, spray dryers, fluidized bed dryers and ovens. Their common feature is that air is used as the heat carrier of the drying medium, and it is in contact with wet materials for heat transfer, and the transfer method is mainly convective transfer. When the temperature of the wet material rises, the moisture in it will turn into steam and be taken away by the air, that is, the mass transfer process. Wet materials can achieve the purpose of drying after heat and mass transfer. [0003] The investment and operating costs of microwave drying are relatively high, so it is...
