Innovative drying technology - MULTI-PASS DRYING SYSTEM
In the field of industrial drying, traditional equipment generally has pain points such as low thermal efficiency, large floor space, and high exhaust gas treatment costs. In response to the industry pain points, we have innovatively developed the multi-circuit drying system, which has successfully broken through the bottleneck of traditional technology through revolutionary structural design and intelligent thermal management, setting a new benchmark for drying processes in the fields of mining, chemical industry, and food processing.
1. Intelligent feeding and distribution control
Material transportation: wet materials are transported to the feed port of the dryer through a closed belt/bucket elevator, and the whole process is dust-free to prevent secondary pollution.
Distribution homogenization: The vibrating screen (±2mm adjustable amplitude) and the spiral distributor are used for coordinated control, and the material layer thickness is accurately adjusted (100-300mm for granular materials and 50-150mm for powder materials) to ensure that the uniformity of hot air penetration reaches more than 95%.
2. Gradient hot air circulation and turbulence optimization
Heat source configuration: The gas/biomass combustion furnace generates high-temperature hot air (up to 800℃) and the hot air enters the drying area through the settling chamber.
Dynamic turbulence technology: 8-12 sets of adjustable spoilers (angle adjustment range 0-45°) are configured, which are adjusted in real time through an external handwheel or electric actuator to form a three-dimensional turbulent field, and the hot air contact efficiency is increased by 60%, and the dead angle area is reduced to less than 5%.
Closed circulation system: After the exhaust gas is cyclone dust removed, 60-75% is recycled to the air distribution chamber, and the waste heat recovery device is combined to preheat the fresh air (energy saving rate ≥ 25%), and the comprehensive thermal efficiency of the system reaches 82%.
3. Multi-stage drying and dynamic material processing
Cocurrent/countercurrent composite drying: The inner cylinder cocurrent zone (material and hot air are in the same direction) realizes rapid dehydration, and the outer cylinder countercurrent zone (reverse flow) completes deep drying, and the moisture gradient control accuracy is ±0.5%.
Lifting-delayed recovery synergy: Built-in 304 stainless steel lifting plate (throwing height 300-500mm) forms a continuous material curtain (specific surface area increased by 4-6 times); intermittent slow recovery section (residence time 3-5min) promotes the migration of moisture inside the material and reduces the risk of thermal fission.
