Nanjing Hjchem‘s high speed centrifugal spray dryer is specially designed for drying concentrated food liquids.
This cutting-edge system integrates globally advanced technologies to efficiently process thermally sensitive, high-sugar substances with low melting points.
The system offers 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.
Centrifugal Spray Drying Mechanism
The compact centrifugal spray drying system converts liquid feedstock into powder through a three-stage process:
Atomization: High-speed centrifugal nozzle disperses liquid into micron-scale droplets at the chamber apex
Airflow Dynamics: Pre-filtered heated air enters via a precision distributor, generating controlled spiral airflow patterns (co-current/counter-current/mixed-flow)
Phase Transition: Rapid heat/mass transfer between droplets and hot gas determines:
Thermal gradients
Particulate motion trajectories
Residence duration
Final product morphology
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.
