for the food industryfor the pharmaceutical industryfor the chemical industry

Description
SD-8000G is a laboratory spray dryer designed for production of microparticle powders in universities, research institutes and R&D/production units in the food, pharmaceutical and chemical sectors. It is suitable for water-based solutions, emulsions and suspensions and for drying heat-sensitive materials thanks to rapid droplet evaporation.

Key points / Short summary

• Two-fluid atomizer with nozzle options: 0.5 / 0.75 / 1.0 / 1.5 / 2.0 mm
• Evaporation rate: 50–2200 mL/h
• Typical drying time: 0.8–1.0 s
• Particle size: 1–25 μm (≈95% in same range)
• Drying chamber: high borosilicate glass
• Suitable for water-based solutions; small amounts of organic solvent possible
• Optional bag filter model: SD-8000GF

Features

• Color touch screen with automatic and manual modes; ten-stage programmable temperature control with memory
• Full-automatic one-button start; automatic peristaltic pump start after parameter and temperature reach
• Manual mode for in-process adjustments with dynamic animation and control
• Immediate stop protection: stop command halts machine except fan to protect components
• Spray, drying and collection parts in high-grade stainless steel; easy disassembly and cleaning
• Organic solvent option includes oil-free imported compressor; low noise operation (<60 dB)
• Compact two-fluid atomization unit; no auxiliary atomization equipment required
• Real-time PID temperature control: accuracy ±0.5–1 °C across range
• Air inlet filter to protect samples
• Peristaltic pump feed control; minimum sample volume approx. 10–50 mL
• Nozzle needle cleaner for viscous feeds: automatic clearing with adjustable frequency
• Tower wall purging and automatic tower cleaning to increase recovery and reduce cleaning time

Process flow
Spray → Glass drying tower → Cyclone or bag filter collection → Sample collection / cold trap (configuration-dependent)
