Spray dryer SD-6000 series

hot airfor the food industryfor the pharmaceutical industry

Product overview

• Classic laboratory spray dryer, cost-effective series
• 2 L/h process capacity
• Glass chamber; stainless-steel chamber available
• Bag filter to prevent dust escape and improve powder yield
• Suitable for food, milk, pharmaceutical and biological samples
• Air compressor included

Application
The SD-6000 Series is designed for laboratory use in universities, research institutes and food, pharmaceutical and chemical companies to produce microparticle powders from emulsions and suspensions. It is suitable for drying heat-sensitive materials (e.g., biological products, biopesticides, enzyme preparations), since the material is only instantaneously heated during atomization, preserving active ingredients.

Structure & materials
The atomization, drying and collection system can be constructed of high-borosilicate heat-resistant glass to provide a contamination-free drying environment; stainless-steel chamber variants are available for specific requirements. The unit integrates atomizing, drying and collection in a compact design without need for auxiliary equipment.

Accessories & options

• Built-in oil-free air compressor (low noise, stable particle distribution)
• Nozzle cleaner (through-needle) with adjustable cleaning frequency for viscous materials
• Air inlet filter to maintain sample purity
• Optional bag filter variant (SD-6000N) for dust collection and higher recovery

Main features

• Color LCD touch screen displaying inlet/outlet temperature, peristaltic pump speed, air volume and nozzle cleaning frequency
• Fully automatic control: one-click start, automatic pump start at preset temperature, animated run display, safe automatic shutdown
• Manual override for in-process parameter adjustments
• Nozzle cleaner with adjustable frequency for automatic clearing of blockages
• Shutdown protection: pressing stop halts machine except fan to prevent damage
• Two-fluid atomizing for uniform particle distribution
• PID real-time temperature control with accuracy ±1 °C
• Adjustable feed peristaltic pump; minimum sample volume ~50–80 ml
• Innovative tower wall purging device for higher material recovery
• Finished powder with relatively uniform particle size distribution
