The tunnel dryer is a machine where a container (tray) filled with the material is placed on a trolley or the material is loaded directly on the trolley, and the trolley is pushed in from the tunnel chamber entrance. The material is dried while being moved through the drying chamber.
Various airflow methods are available for the tunnel dryer,such as horizontal airflow, vertical airflow and alternating airflow, selected according to factors such as the material properties and drying conditions.

- 1. Suitable for drying materials for a long time, and large volumes can be processed.
- 2. Uses a zone control system responsive to the drying progress conditions, which enables effective drying with high thermal efficiency.
- 3. The automated system (fully automated/semi-automated) saves labor.
- 1. Materials vulnerable to shape damage, such as frozen tofu and roux.
- 2. Construction materials, such as rock wool boards, calcium silicate boards and plywood boards.
- 3. Electrical or mechanical parts, such as IC boards and automobile parts.
- 4. Other various industrial materials, such as granular clumps and molded parts.
- 5. Various materials that require drying for a long time.
