Background
Drying generally refers to the process of heating heat above a wet material and removing the moisture from the material side by side to obtain a solid product with a lower moisture content. In thermal drying, the following two processes occur sequentially, with the drying rate being controlled sequentially. Process 1, the transfer of energy from the surrounding environment to the surface of the material, causing the surface moisture of the material to evaporate and the liquid to be discharged from the surface of the material in vapour form, the rate of which depends on the conditions of temperature, air humidity, air flow rate, heat transfer area and pressure of the material, also known as the constant drop drying process. And (2) a process: the internal moisture is transferred to the surface of the material, and surface evaporation occurs; the migration of moisture within the material is a function of the material properties, temperature and humidity, and this process is also known as the falling rate drying process.
State of moisture: under the condition of certain temperature and water content, the surface of the material has certain water vapor pressure P1, and the size of the material is different with the temperature and the water content. The material has higher water content, the water vapor pressure on the surface of the material is higher, if the water vapor pressure on the surface of the material P1 is higher than the water vapor pressure in the air P2, namely P1 is more than P2, the material is dehydrated and dried, and the process is called analytic drying; if P1 < P2, the material will absorb water vapour from the surrounding air, called adsorption. When the air pressure of the moisture content of the surface of the material is equal to the water vapor pressure of the surrounding air, namely P1= P2, the moisture content in the material is not changed any more, a dynamic equilibrium state appears, the moisture content is called equilibrium moisture, the moisture content of the material exceeds the equilibrium to be free moisture, and the moisture can be removed by a drying method.
