Spray Dryer Application:
SD-3SR is designed for heat-sensitive materials that are highly prone to deactivation, oxidation, or vaporization during conventional high-temperature drying. With vacuum (negative pressure of 0.03–0.06 MPa) to lower the solvent vaporization temperature, achieves instantaneous spray drying from 50°C to 80°C. Suitable for biological products, high-sugar extracts of traditional Chinese medicines and natural products, heat-sensitive polymer materials, and specialized materials prone to vaporization upon heating.
Spray Dryer Feature:
9" color touchscreen for real-time parameter display, supports historical data and trend curve queries, ensuring process traceability.
Operates in a vacuum environment (0.03–0.06 MPa) at low temperatures (50–80°C), allowing heat-sensitive materials to dry without exposure to high heat.
Constructed from stainless steel with quick-connect fittings for the drying system, easy to disassemble and clean, minimizing the risk of cross-contamination.
Built-in oil-free air compressor prevents oil mist contamination of samples; produces powder particles with a normal size distribution.
Two-fluid atomization structure; compact design requires no auxiliary equipment and has a small footprint.
Supports sample volumes as low as 30 mL, reducing loss for valuable or scarce samples.
PID temperature control with ±1°C precision and PT100 sensors ensures accurate temperature regulation and process reproducibility.
Over 95% of the dry powder falls within the same particle size range, improving repeatability for downstream packaging and testing.
Nozzle cleaner (cleaning pin) for viscous materials, automatically clears nozzle blockages with adjustable cleaning frequency.
Operational protection features provide continuous monitoring of parameters such as oxygen concentration, condensation temperature, and filter differential pressure.
Automatic pressure relief in the event of a vacuum system anomaly reduces operational risk.
Shutdown protection function: the entire unit stops immediately upon shutdown, except for the fan.
Modular design consisting of a spray drying unit and a vacuum low-temperature system; allows for seamless switching between high-temperature spray drying and vacuum low-temperature drying.
