What is the drying principle and process?

2019/12/10 15:06:16      c
The drying process is the heat exchange and humidity exchange between the green body and the drying medium during tunnel drying. The heat medium transfers its own heat to the green body and absorbs the moisture diffused from the green body. The temperature itself decreases and the humidity increases. The gas with low moisture content becomes low temperature and high humidity gas with lower temperature and larger moisture content.

   The sintered brick body absorbs the heat transferred from the heat medium and the temperature rises, and the moisture contained in it is discharged, and the weight is reduced. From the low temperature, high temperature, and heavy wet billet, it gradually becomes higher in temperature, lower in moisture content and lighter in weight. High temperature and low water content body.

In the drying and heating stage, the heat transferred from the heat medium to the body is used to evaporate the water in the body, and there is a certain amount of heat surplus. Due to the lower body temperature and the higher heat medium temperature, Under the action, the surplus heat is used to heat the green body and increase the temperature of the green body.
