Belt dryer is a common drying equipment. Its working principle is to send the high humidity material into the dryer through the conveyor belt. After heating, the water gradually evaporates, and then the moisture is discharged through the exhaust fan, so as to achieve the purpose of drying.
Specifically, the belt dryer is mainly composed of conveyor belt, heater, fan and so on. The material is transmitted to the heater through the conveyor belt, and the water on the surface of the material begins to evaporate after being heated by the hot air in the heater. As the material moves, the water gradually evaporates until the material is completely dry. The exhaust fan pulls the air with water vapor out of the dryer, so as to ensure that the relative humidity inside the dryer is lower than the ambient humidity and ensure the drying effect of the material. Finally, the material is exported from the outlet of the dryer and the whole drying process is completed.
Belt dryer has the advantages of fast drying speed, high efficiency and good drying quality, which is widely used in food, chemical, pharmaceutical and other industries. At the same time, when using the belt dryer, it is necessary to pay attention to the input amount of materials, temperature, humidity and other factors to ensure the stability of the drying process and the drying effect of materials.
