Nanjing Hjchem‘s centrifugal spray dryer is specially designed for drying herbal extracts and concentrated food liquids.
Incorporating advanced international technology, it effectively handles heat-sensitive, high-sugar materials with low melting points.
The system tailors drying conditions to product characteristics, offering high automation, user-friendly operation, and full compliance with GMP standards.
Its successful development resolves long-standing challenges in drying sugar-rich, low-melting-point products, making it ideal for preliminary research, small-scale trials, pilot testing, and industrial-scale production in universities and enterprises.
Working Principle of Centrifugal Spray Dryer
This compact centrifugal spray dryer transforms liquid feed into fine droplets via an atomizer, which then contact hot air (or other gases) to produce powdered products.
Filtered and heated air enters through a top-mounted distributor, spiraling uniformly into the drying chamber.
The feed liquid is atomized by a high-speed centrifugal nozzle at the tower’s apex, creating ultra-fine mist droplets.
Heat and mass transfer occur rapidly as droplets and hot air interact in co-current, counter-current, or mixed-flow patterns—critically influencing temperature distribution, particle trajectory, residence time, and final product properties.
Dried powder is collected at the tower base, while residual fines are separated via a cyclone, exhaust gas is discharged by a fan.
Key Features
Rapid Drying: our Y-LPG model achieves drying in 5–15 seconds. Atomization maximizes surface area, enabling 95–98% moisture evaporation instantly—perfect for heat-sensitive materials.
Preserved Quality: Short drying time retains color, aroma, and taste. High-purity products with consistent quality.
Superior Particle Properties: Spherical droplets yield powders with excellent dispersibility, flowability, and solubility. Automated controls ensure stable operation.
Streamlined Process: Directly dries liquids with 40–60% moisture (up to 90% for specialty materials) into powders, eliminating crushing/sieving. Adjustable parameters (particle size, density, moisture) for precise control.
Versatile Feed Compatibility: Processes solutions, slurries, emulsions, suspensions, pastes, melts, and even filter cakes.
Uniform Output: Consistent particle uniformity, solubility, and high purity.
