(1) The heat transfer effect is good, the temperature inside the bed is relatively uniform, and the heat capacity coefficient (or volume heat transfer coefficient) is high, and the production capacity is large;
 
(2) Due to the uniform temperature distribution in the fluidized bed, any local overheating of the product can be avoided, so it is especially suitable for the drying of certain heat sensitive materials (such as grinding, polyacrylamide, etc.);
 
(3) Continuous operation can be performed in the same equipment, and intermittent operation can also be performed;
 
(4) The residence time of the material in the dryer can be adjusted as needed, so the moisture content of the product is stable;
 
(5) Independent electrical cabinet and PLC human-computer interaction operation control, integrated all drying parameter settings, safe and convenient operation;
 
(6) The drying device has few mechanical transmission components, the investment cost of the equipment is low, and the maintenance workload is small.
 
What are the factors affecting large microwave dryer dryers?
 
The dryer has many heating methods, and the common heating method is convection heating. There are many factors affecting the dryer dryer during the drying process. The following is a simple analysis:
 
Convection heating is the most versatile way of drying granules, radial or paste materials. Heat is supplied by hot air or other gas flowing through the surface of the stream or through the layer of material, while the evaporated moisture is carried away by the drying medium. Air (the most common medium), inert gas, direct combustion gas or superheated steam (or solvent vapor) can be used as a heating medium for convection drying systems. The direct (heating) dryer is in the initial constant-speed drying stage, and the surface temperature of the material is the wet bulb temperature corresponding to the heating medium. During the slow drying phase, the temperature of the material gradually approaches the dry bulb temperature of the medium, and these factors must be taken into consideration when drying the heat sensitive material. When the dryer is dried by superheated steam, the maximum temperature of the material corresponds to the saturation temperature at the operating pressure.
