It is understood that the mesh belt dryer is a continuous drying equipment for mass production, which is used for drying flakes, strips, granules and some paste materials with good gas permeability. Especially suitable for traditional Chinese medicine decoction pieces and other high moisture content, heat sensitive materials. It has the advantages of high drying rate, high evaporation strength and good product quality.
According to the structure, mesh belt dryers can be divided into various types. Common ones are single-stage mesh belt dryers, multi-stage mesh belt dryers, multi-layer mesh belt dryers, and impact belt belt dryers.
Among them, the working principle of the single-stage mesh belt dryer is that the material to be dried is uniformly distributed from the feeding end to the conveying belt through the feeding device. The drying cabinet is usually divided into several units to independently control the operating parameters and optimize operation. There is also an isolation section between the drying sections where no drying medium circulates.
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 that of the single-stage mesh belt dryer.
Multi-layer mesh belt dryers are often used in areas where drying speed requirements are low, drying time is long, and process operating conditions are kept constant throughout the drying process. It is reported that the multi-layer mesh belt dryer is widely used in dry grain materials due to uniform material drying, small floor space and simple structure. However, it is not suitable for drying sticky and brittle materials due to multiple loading and unloading during operation.
The impact belt dryer is usually composed of two conveyor belts, which can be separated into unit sections for independent control. The working principle is that after the drying medium is humidified, it is partially discharged, and the other part is returned to be mixed with fresh drying medium and then circulated. It is generally suitable for the drying of dry fabrics, tobacco leaves, surface coatings of substrates and other flaky materials.
At present, mesh belt dryers are widely used in the fields of traditional Chinese medicine, dehydrated vegetables, and grain drying. In recent years, with the increasing competition in the market, dryer equipment manufacturers must break the tradition and accelerate the upgrading and upgrading of products. Improve the core competitiveness of products in the market.
For example, most of the belt dryers currently on the market do not have a cleaning function. One dryer can only dry one material, and if it is not cleaned thoroughly, it will pollute other materials, which brings a lot of drying operators. Troubled. In addition, in recent years, the requirements for the production and circulation of traditional Chinese medicine decoction pieces have been improved, so enterprises must pay attention to and improve.
It is reported that some companies have continuously broken through and obtained patents on the road of technological innovation. It is reported that the company has upgraded and upgraded the internal structure of the existing belt dryer, overcoming the deficiencies of the original technology, adding a cleaning system, and enabling the dryer to thoroughly clean the material after drying.
At the same time, the cleanliness of the dryer is fully guaranteed, and the phenomenon of cross-contamination during the drying process of a dryer is avoided. In addition, it also satisfies the diversified demand that a dryer can dry a variety of materials, and provides a belt dryer which is convenient to clean, safe and hygienic, adaptable, convenient to operate, stable in quality and high in drying efficiency.
It is reported that some users have reported that after the new belt dryer is put into production, the production efficiency is greatly improved, not only the product quality is improved, but also the company has not saved the cost.
In general, under the current situation, mesh belt dryer manufacturers must continue to innovate, further enhance the technical content, and promote product optimization and upgrading.
