The prospect of mesh belt dryer is considerable. The cleaning needs to be optimized and upgraded

It is understood that the 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 high moisture content and heat sensitive materials such as Chinese herbal pieces It has the advantages of high drying rate, high evaporation intensity and good product quality According to the different structure, the mesh belt dryer can be divided into many types Common such as single-stage mesh belt dryer, multi-stage mesh belt dryer, multi-layer mesh belt dryer, impact mesh belt dryer, etc Among them, the working principle of single-stage mesh belt dryer is that the dried materials are evenly distributed to the transmission belt from the feeding end to the feeding device The drying cabinet is usually divided into several units to control the operation parameters independently and optimize the operation And there is an isolation section between the drying sections, where there is no drying medium circulation It is reported that the multi-stage mesh belt drying is essentially composed of several single-stage mesh belt dryers in series, and its operation principle is the same as the single-stage mesh belt dryer The multi-layer mesh belt dryer is often used in the field where the drying speed is low and the drying time is long It is reported that the multi-layer mesh belt dryer is widely used for drying grain materials because of its uniform drying, small floor area and simple structure However, it is not suitable for dry, sticky and fragile materials due to multiple loading and unloading during operation The impact type mesh belt dryer is usually composed of two conveyor belts, which can be separated into unit sections for independent control Its working principle is that after the drying medium is humidified, part of it is discharged, and the other part is returned to mix with fresh drying medium for circulation It is usually suitable for drying the surface coating of fabrics, tobacco leaves, base materials and other sheet materials At present, the mesh belt dryer is widely used in traditional Chinese medicine, dehydrated vegetables, grain drying and other fields In recent years, with the increasingly fierce market competition, the dryer equipment manufacturers must break the tradition, accelerate the update and upgrading of products, in order to improve the core competitiveness of products in the market For example, most of the belt dryers on the market do not have the cleaning function at present One dryer can only dry one kind of material, and if the cleaning is not thorough, it will pollute other materials, which brings great trouble to the drying operators And in recent years, the production and circulation of Chinese herbal pieces have been improved in all aspects, so enterprises must pay attention to and improve It is reported that the enterprise has upgraded the internal structure of the existing belt dryer, overcome the shortcomings of the original technology, and increased the cleaning system, which can realize the thorough cleaning of the dryer after drying materials At the same time, the cleanliness of the dryer is fully guaranteed, and the phenomenon of cross contamination in the drying process of multiple materials using a dryer is avoided In addition, the utility model also meets the diversified requirements of a dryer for drying various materials, and provides a belt dryer with convenient cleaning, safety and health, strong adaptability, convenient operation, stable quality and high drying efficiency It is reported that some users have reported that after the new belt dryer is put into production, the production efficiency has been greatly improved, not only the product quality has been improved, but also the cost has not been saved by the enterprise In general, under the current situation, the mesh belt dryer manufacturers must continue to innovate, further improve the technical content, and promote product optimization and upgrading.
