DWD seriesDehydrated vegetable belt dryerIt is the third generation belt dryer developed and produced by our company based on years of practical experience and advanced technology of similar products at home and abroad, on the basis of the company's second-generation DWT belt dryer. This machine overcomes and compensates for the shortcomings of DWT series equipment in practical use of some materials, making the structure of the belt dryer more complete and reasonable, with a wider range of applications, stable and convenient operation, and high thermal efficiency.

The main structural features are: 1. The heat exchanger is arranged separately from the mesh belt drying chamber, and a separate heat exchanger chamber is set up on the side of the drying chamber to effectively avoid adverse contact between material particles and the heat exchanger, such as the leakage of particles on the heat exchanger affecting the heat transfer effect. 2. The hot air circulation method has been changed from longitudinal multi unit series flow to lateral unit circulation, achieving independent circulation of each unit, forced ventilation, effectively increasing the circulating air volume, bringing many advantages such as high penetration of hot air, high heat utilization rate, and good controllability of units, with high stability and high efficiency and energy saving. It is an ideal and reliable production equipment for a wide range of users.

working principle

The material to be dried is evenly distributed on a variable speed running mesh belt through a suitable feeding device. During drying, hot air flows through the gaps between the mesh belt and the material from top to bottom, making each surface of the dried material a heating surface. This significantly increases the heat exchange contact area between the material and the hot air, shortening the evaporation and diffusion distance of moisture inside the material. Therefore, an excellent drying operation can be carried out. The independent lateral circulation of the hot air unit enhances the penetration of hot air, and makes temperature and air volume control more flexible and convenient, thus having a wider adaptability to materials of different types and properties.

Scope of application

Widely applicable to industries such as food, chemical, pharmaceutical, feed, pigments, dyes, mineral products, building materials, etc., for drying granular, block, flake, crystalline, and cake like materials.

Product Features

1. The heat exchanger is arranged separately from the mesh belt drying chamber, and a separate heat exchanger chamber is set up on the side of the drying chamber to effectively avoid poor contact between material particles and the heat exchanger.
2. The hot air circulation method has been changed from vertical multi unit series to lateral unit circulation, achieving independent circulation control of each unit, effectively increasing the circulation air volume, bringing many advantages such as high penetration of hot air, high heat utilization rate, high energy efficiency, flexible unit control, and good controllability.
3. Without damaging the shape of the material, the material moves in a stationary state inside the dryer, and there will be no mechanical damage to the shape of the material.
4. Users can set appropriate operating conditions and flexibly adjust temperature, air volume, mesh belt running speed, and other operating conditions according to the hot air circulation mode and drying state.
5. Free adjustment of the moisture content of the finished material, as the flow rate and residence time of the material in the dryer can be freely adjusted, the moisture content of the processed product can be set arbitrarily.

Technical Specifications

Note: 1. When selecting, users should choose based on parameters such as production capacity and material moisture content. 2. Multiple units are connected in series to increase the drying area, meet usage requirements, and improve product yield and quality. 3. The standard model conveyor belt is made of stainless steel wire mesh, and users can choose stainless steel chain plate steel strip, stainless steel mesh belt, or PTFE non stick mesh belt according to their needs.
