The types of air dryers include airflow dryers, rotary drum dryers and fluidized bed dryers.
Airflow dryers use high-speed airflow to transfer heat and mass through materials, and are suitable for drying, curing, baking and other processes of various materials and products.
The rotary drum dryer bakes the material in the rotating drum with hot air to evaporate the moisture in the material to achieve the purpose of drying. It is suitable for drying materials with high humidity, such as powder and granular materials.
The fluidized bed dryer is a device that uses multiple layers of continuously running hot air boxes and conveyor belts to place the material on the conveyor belt for drying. It is often used for drying flaky materials in the fields of food, chemical industry and agriculture.
In addition, the classification of convection drying also includes natural drying, box drying, tunnel drying, conveyor belt drying, fluidized bed drying, airflow drying and spray drying. These classifications are based on different drying conditions and material characteristics to meet the needs of various industrial production.
