Chenghai Company's HSUP series vibrating fluidized bed dryers are a revolutionary advancement in drying technology, surpassing traditional fixed and vibrated fluidized bed systems produced by domestic manufacturers. These dryers are capable of handling a wide range of solid materials using dual vibrator technology, ensuring efficient and energy-saving drying processes. In the citric acid industry, Chenghai’s dual-mass vibrating fluidized bed is recognized as one of the best in the country and even internationally, due to its superior performance, advanced design, and high-quality results.
Unlike conventional systems, the HSUP series eliminates common issues such as wall adhesion, channeling, dead zones, and poor material flow. The equipment incorporates a new vibration mechanism and advanced technologies that overcome the limitations of traditional drying methods. This ensures a stable and uniform excitation force, with the bed surface maintained flat through leaf spring positioning. Combined with horizontal air distribution technology, it guarantees consistent material movement without agglomeration, sticking, or backmixing.
The system allows for long bed lengths—up to 20 meters—enabling the efficient drying of large, high-moisture, or difficult-to-handle materials like fibrous substances, ultrafine powders, and heavy-density particles. The powerful automatic control system optimizes energy use, reducing consumption compared to other dryers on the market.
One of the key features of the HSUP series is its ability to achieve a plug-flow (sub-fluidized) state, where the material moves uniformly without mixing. This minimizes air usage, reduces heat loss, and ensures precise temperature and humidity control. The sub-fluidized state also prevents particle damage, maintains product integrity, and enhances thermal efficiency.
With airflow velocities ranging from 0.2 to 5 m/s, the system supports various processes such as granulation, coating, drying, sterilization, and solvent recovery. The adjustable vibration frequency allows precise control over residence time, ensuring even drying and preventing overheating or allergic reactions.
The HSUP series offers flexible design options, including customizable bed surfaces, adjustable drying temperatures, and optimized bed areas. It can handle materials up to 60 mm in size and operate at temperatures as high as 600°C, making it ideal for high-temperature drying applications.
Compared to belt dryers, the HSUP series provides higher drying capacity, faster processing, and better performance in low-temperature conditions. Its large single-bed area of 44 m² allows for high throughput without the need for multiple beds in series.
Additionally, the equipment includes built-in dust removal systems, eliminating the need for external cyclones or bag filters. It features user-friendly design, easy maintenance, and self-cleaning functions, reducing operational burden. Automation and stability ensure reliable performance with minimal supervision.
Overall, the HSUP series represents a significant leap in drying technology, offering energy efficiency, versatility, and superior product quality across a wide range of industrial applications.
