Drying equipment is a device for drying operation. The moisture in the material (generally refers to moisture or other volatile liquid composition) are heated to Vaporization escape, to obtain the Specified moisture content of solid materials.

    Drying process requires a lot of heat energy. In order to save energy, the material with high moisture content needs to be mechanically dehydrated or heated, then drying in the dryer.

    The transfer of heat and mass (moisture) is required in the process of drying. To ensure the surface moisture of the material is higher than the external pressure. Ensure that the heat source temperature is higher than the material temperature.

    Heat is passed to wet material in various ways. The material surface moisture vaporization and escape into outer space. The moisture content between the surface and the inner surface of the material is different. The internal wetted surface diffusion and evaporation, so that the material moisture content continues to decrease, and gradually complete the overall drying of the material.

    The export scale of China's drying equipment is small. Export volume is less than 5% of the total, and mainly sold in Southeast Asia. However, according to the authority, with the development of technology, the total output of China's exports proportion in the next few years will be increased from 5% to 10%, the export market will expand to Europe and the United states.
