    Mesh belt dryer is a continuous drying equipment for mass production, which is used for drying flaky, strip, granular and partial paste materials with good air permeability It is especially suitable for dehydrated vegetables, Chinese herbal pieces and other materials with high moisture content and heat sensitivity It has the advantages of high drying rate, high evaporation intensity and good product quality The mesh belt dryer is composed of several independent unit sections The operation parameters of drying medium quantity, temperature, humidity and tail gas circulation quantity can be controlled independently, so as to ensure the reliability of the mesh belt dryer and the optimization of operation conditions The operation of mesh belt dryer is flexible, wet material is fed, and the drying process is carried out in a completely sealed box The working conditions are good, and the dust leakage is avoided The characteristics of the mesh belt dryer (1) the vibration and impact of the material on the mesh belt dryer are slight, and the material particles are not easy to be pulverized and broken, so it is also suitable for drying some materials that are not allowed to be broken (2) the mesh belt dryer is not only used for drying materials, but also for baking, burning or curing of materials (3) the structure of the mesh belt dryer is not complex, easy to install, and it can operate for a long time In case of failure, it can enter the box for internal maintenance, which is convenient for maintenance Structure form of mesh belt dryer (1) single-stage mesh belt dryer: dried materials are evenly distributed to the transmission belt from the feed end through the feeding device The conveyor net belt is usually made of perforated stainless steel sheet, driven by the motor through the gearbox net, and can be adjusted The drying cabinet is usually divided into several units to control the operation parameters independently and optimize the operation There is an isolation section between the drying sections, where there is no drying medium circulation (2) multistage mesh belt dryer: multistage mesh belt dryer is essentially composed of several single-stage mesh belt dryers in series, and its operation principle is the same as that of single-stage mesh belt dryer (3) multi layer mesh belt dryer: multi layer mesh belt dryer is often used in the situation that the drying speed is low and the drying time is long, and the process operation conditions can be kept constant during the whole drying process A partition board is arranged between layers to organize the directional flow of drying medium so as to make the material dry evenly The multi-layer mesh belt dryer is widely used for drying grain materials due to its simple structure and less floor space However, due to multiple loading and unloading during operation, it is not suitable for drying the materials that are easy to adhere to the conveyor belt and are not allowed to break (4) impact type mesh belt dryer: the impact type mesh belt dryer is suitable for drying the surface coating of fabrics, tobacco leaves, base materials and other sheet materials The impact belt conveyor is usually composed of two conveyor belts The impact mesh belt conveyor can be divided into unit sections for independent control After the drying medium is humidified, part of it is discharged, and the other part is returned to the fresh drying medium for circulation.
