A conveyor dryer is a type of drying equipment that utilizes a conveyor belt to transport materials through a heated chamber for drying. Here's how it works:

1. Conveyor Belt: The key component of a conveyor dryer is the conveyor belt. This belt is typically made of a heat-resistant material such as stainless steel mesh or Teflon-coated fiberglass. It moves continuously through the drying chamber, carrying the material being dried.
2. Heated Chamber: The conveyor belt passes through a heated chamber where hot air or other drying agents are circulated. The heating method can vary and may involve electric heaters, gas burners, infrared lamps, or steam coils. The temperature within the chamber is carefully controlled to ensure efficient drying without damaging the material.
3. Material Loading and Unloading: The material to be dried is loaded onto the conveyor belt at the entrance of the dryer. As the belt moves through the heated chamber, the material is exposed to the drying conditions. Once the material reaches the end of the conveyor belt, it is typically cooled down and unloaded from the dryer.
4. Adjustable Speed: The speed of the conveyor belt can usually be adjusted to control the residence time of the material within the drying chamber. This allows operators to optimize the drying process for different types of materials and desired moisture levels.
5. Applications: Conveyor dryers are used in a wide range of industries for drying various materials, including textiles, food products, plastics, ceramics, and more. They are particularly well-suited for drying items that are flat or have a uniform shape, such as fabric rolls, printed substrates, and coated paper.
