The main working principle of the Box Dryer is to dry the wet material with hot air to achieve the evaporation and drying of the moisture in the material. Its working principle can be elaborated as follows:
Heating process:
The Box Dryer first heats the air to a set high temperature state through a heater. This process is the basis for the operation of the dryer, and high-temperature air is the key factor in achieving material drying.
Hot air circulation:
The heated hot air enters the drying chamber through a specific pipe driven by the fan. In this process, the temperature and flow rate of the hot air can be adjusted as needed to meet the drying needs of different materials.
The hot air contacts the wet material in the drying chamber, transfers heat to the material through heat conduction and convection, and gradually evaporates the moisture in the material.
Material drying:
The wet material is placed on a tray or conveyor belt in the drying chamber. As the hot air flows, the moisture on the surface of the material begins to evaporate.
During the drying process, the hot air will continuously pass through the material layer, gradually bringing out the moisture inside the material, thereby achieving overall drying of the material.
Dehumidification and cooling:
As the moisture evaporates, a large amount of humid air will be generated in the drying chamber. These humid air needs to be discharged in time through the dehumidification system to prevent excessive humidity from affecting the drying effect.
When the material is dried to a certain degree, it needs to be cooled to prevent the material from continuing to release moisture or undergoing other changes in a hot state. The cooling process is usually achieved by adjusting the temperature of the air entering the drying chamber.
Control system:
Box Dryer is usually equipped with an advanced control system, which can automatically adjust parameters such as heating temperature, wind speed, humidity, etc. according to the characteristics of the material and drying requirements to achieve the best drying effect.
The control system can also monitor and record the drying process in real time, which is convenient for users to analyze and optimize the drying process.
In summary, Box Dryer achieves fast and efficient drying of wet materials through the synergy of multiple links such as heating, hot air circulation, material drying, dehumidification and cooling, and control system.
