Chenghai Company's HSUP series vibrating fluidized bed dryers are a revolutionary advancement in drying technology, surpassing traditional fixed and vibrated fluidized bed systems commonly used by domestic manufacturers. These dryers are designed to handle any solid material using a dual-vibrator system that ensures efficient, energy-saving drying. In the ammonium sulfate industry, Chenghai’s dual-mass vibrating fluidized bed is recognized as one of the most advanced solutions globally, excelling in design, performance, and product quality while overcoming the limitations of conventional systems.
The HSUP series incorporates an innovative vibration mechanism and structural design, integrating advanced technologies to eliminate the inefficiencies of older systems. It replaces traditional two-side motor-driven vibrations with a more stable and synchronized excitation force. The bed surface is supported by leaf springs, ensuring a flat and uniform distribution, while horizontal air distribution prevents issues like clogging, agglomeration, or sticking. This system allows for longer beds—up to 20 meters—enabling the stable transport of materials with high moisture content, large particle size variations, fibrous structures, ultrafine powders, and more.
Equipped with a powerful automatic control system and scientific optimization technology, the HSUP series ensures minimal energy consumption while maintaining precise process control. Compared to other dryers on the market, Chenghai’s equipment offers superior energy efficiency, reducing operational costs significantly.
One of the key advantages of the HSUP system is its ability to achieve a near-Plug Flow (sub-fluidized) state. This ideal fluidization condition ensures that particles move uniformly without backmixing, resulting in even drying and reduced air requirements. The low wind speed minimizes particle friction, preserving product integrity and preventing overheating or sintering. Additionally, the sub-fluidized state enhances heat and mass transfer efficiency, allowing for better thermal utilization and lower exhaust temperatures.
The system supports a wide range of airflow velocities (0.2–5 m/s), making it suitable for various processes such as rewetting granulation, coating, sterilization, calcination, and solvent recovery. With adjustable vibration frequency, the residence time of the material can be precisely controlled (5–160 minutes), ensuring consistent temperature and humidity levels throughout the drying process.
The flexible design allows for arbitrary bed surface configurations, enabling operators to adjust drying time and temperature according to specific material needs. A single bed area of up to 44 m² provides high throughput and eliminates the need for multiple beds in series, even for materials requiring long drying times.
In addition to its drying capabilities, the HSUP series features user-friendly design elements, including self-cleaning mechanisms, easy installation, and minimal maintenance. The built-in dust collection system captures airborne particles directly into the bed, eliminating the need for additional dust removal equipment.
Overall, the HSUP series represents a significant leap forward in fluidized bed drying technology, offering unmatched efficiency, versatility, and reliability for a wide range of industrial applications.
