Medium Wave IR Curing and Circulation Hot Air Drying Tunnel Screen Printing Conveyor Dryer

Quick Detail:
1.Most of hot air is circled inside the oven. The heat efficiency is high and the energy source can be saving.
2.Using enhanced ventilation and adjustable air separating boards. It can make materials dried uniformly. The heat source can be steam, heat conductive oil, electricity or far infrared.
3.The machine makes little noise and can be operated stably. The temperature can be controlled automatically and the installation and maintenance are all very convenient.
4.With wide scope of application, it is suitable for drying varieties of materials. So it is a current type of drying equipment.

Working principle

The drying process requires a lot of heat. In order to save energy, some materials with high moisture content, suspensions or solutions containing solid substances are usually first mechanically dehydrated or heated to evaporate and then dried in a desiccator to obtain a dry solid.

Heat is transferred from the high temperature heat source to the wet material in various ways, causing the surface of the material to evaporate and escape to the external space, thereby producing a difference in moisture content on the surface and inside of the material. The internal moisture diffuses to the surface and evaporates, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed.
