During the drying, material’s moisture content is gradually reduced till to the end of drying. At the end of the conveyor film, material be cooled though low temperature water. It helps material be removed from the conveyor film and it can reduce temperature’s affect to product’s quality. By controlling the running speed of the conveyor film, the drying time can be adjusted.
Thin-layer drying system, usually use hot fluid as heating medium (usually water), hot fluid surface be covered with the conveyor film which are made of a special material with poor heat conduction. So, circulating water’s thermal energy loss is limited.
Adopting thin layer distribution system, the moisture meet less resistance when escapes. At same time, air draft device be installed at the upper part of heating surface, in this way evaporated moisture can be removed in time, strengthen the dehydration, so even at atmospheric pressure, it can reach a larger evaporation capacity to meet the drying production requirement.
