Characteristics and Applications of Centrifugal Spray Dryers

Characteristics and Applications of Centrifugal Spray Dryers (Centrifugal Spray Dryers) are as follows:

I. Characteristics

Rapid Drying Speed

Liquid materials are dispersed into minute droplets (diameter 10-200 microns) by a high-speed centrifugal atomizer, dramatically increasing surface area. Upon contact with hot air, 95%-98% of moisture evaporates instantly, achieving instantaneous drying within 5-15 seconds.

Superior Product Quality

Uniformity: Narrow particle size distribution with regular particle morphology (primarily solid or spherical particles) and excellent flowability.

Solubility: Rapid dissolution rate and high purity, suitable for applications demanding stringent quality standards.

Suitable for Heat-Sensitive Materials: Short drying time preserves material color, aroma, flavor, and active components (e.g., vitamins, enzyme preparations).

Streamlined Production Process

Continuous Operation: Liquid materials with 40%-90% moisture content can be dried into powder in a single step, eliminating post-processing like grinding and screening to reduce production stages.

Automated Control: Precise adjustment of parameters like feed rate and hot air temperature enables accurate control over particle size, bulk density, and moisture content, ensuring user-friendly operation.

High Adaptability

Wide Material Range: Processes diverse forms including solutions, emulsions, suspensions, and pastes, accommodating high-viscosity liquids (e.g., resins, starch slurries).

Flexible Capacity: Models span laboratory R&D (e.g., QFN-L-3) to industrial production (e.g., QFN-L-20 or custom configurations), handling 50-500 kg/hour.

Energy Efficiency & Environmental Protection

High thermal efficiency: Recirculates hot air to reduce energy consumption.

Sealed design: Minimizes dust emissions and meets environmental standards.

Structural & Maintenance Advantages

Durable atomizer: Centrifugal atomizer resists clogging and handles fibrous materials effectively.

Easy cleaning: No internal dead corners ensure thorough sanitation, compliant with GMP standards.
