Overview
This fully automatic drying system is designed for crystalline sugars, sugar alcohols, and other crystalline products, including dextrose, sucrose, xylitol, maltitol, erythritol, mannitol, sorbitol, fructose, citric acid, MSG, and amino acids. GMP-compliant units available for pharmaceutical applications. Also serves petrochemical, biopharmaceutical, and food processing industries.
Working Principle
Crystal granules fall by gravity into a cylindrical fixed fluid bed dryer, fluidized by hot air from the bottom for rapid moisture removal. After pre-drying, crystals pass through a rotary airlock valve to a rectangular vibrating fluid bed dryer for final drying, then to a cooling section with cold air. Finally, cooled crystals are discharged to a vibrating screen where oversized agglomerates are removed.
Key Features
Two-stage drying -Pre-drying and final drying in separate units maximizes efficiency, saves energy, and achieves lower final moisture.
No caking Low moisture + thorough cooling prevents caking during storage and transport.
Uniform quality- Special sieve plate design eliminates short-circuiting, ensures even drying and stable product quality.
Prevents product loss - Sieve structure stops crystals from falling into air duct when air supply stops.
Technical Specifications
Square Vibrating Fluidized Bed: Low frequency, high amplitude; special perforated plate for uniform air distribution; standard motor drive.
Circular Counter-current Fluidized Bed: Main drying removes 95-99% moisture; fluidization height 1-2m; counter-current contact for 20-30 minutes; energy saving up to 70%.
