The drying process consumes a lot of heat energy. The three-in-one filter, washing and drying machine, in order to save energy, some materials with high moisture content, suspensions or solutions containing solid substances are generally dehydrated mechanically or evaporated by heating, and then dried in the dryer. , filter the washing and drying machine three-in-one plant to get dry solids.
During the drying process, the transfer of heat and mass (moisture) needs to be completed at the same time. The three-in-one filter, washing and drying machine ensures that the partial pressure (concentration) of the moisture vapor on the surface of the material is higher than that of the moisture vapor in the external space, ensuring that the heat source The temperature is higher than the material temperature.
The heat is transferred from the high-temperature heat source to the wet material in various ways, so that the moisture on the surface of the material is vaporized and dissipated to the external space, so that there is a difference in the moisture content between the surface and the inside of the material.
The internal moisture diffuses to the surface and vaporizes, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed.
