What are the characteristics of a convection dryer?
The quality of water vaporization units with energy conduction type dryer high end products, especially when moisture content is low
When using low temperature air flow, the airflow must be treated by dehumidifying first
The humidity of the airflow has an effect on the drying rate and the final moisture content of the product
The temperature of the hot gas stream can be increased to the maximum temperature (about 730 DEG C) that the common metal material can tolerate. The radiation heat transfer will become the main mode of heat transfer at high temperature, and can achieve a high utilization rate of heat
The hot gas flows in direct contact with the solid, and the heat is passed from the heat to the wet solid by convection heat transfer, and the water vapor is carried away by the airflow
