3L Centrifugal Spray Dryer Drying Machine for Milk Blood Coffee Powder Making
Small-scale spray dryer suitable for universities, research institutes, and industrial laboratories (food, pharmaceutical, and chemical) to produce micro-scale powdered particles. Broad applicability for solutions such as emulsions and suspensions, ideal for drying heat-sensitive materials like biological products, bio-pesticides, and enzyme preparations (excluding organic solvents).
Sprayed material is only exposed to high temperatures when atomized into fine droplets, ensuring instantaneous heat exposure that preserves active ingredients after drying.

- Read Manual Thoroughly: Review this manual carefully before operating to ensure safe and correct use
- Organic Solvents Prohibited: Designed for aqueous solutions only - organic solvents create severe fire and explosion hazards
- High-Temperature Surfaces: Machine surfaces become extremely hot during and after operation - avoid direct contact
- Observation Door Safety: Never open observation door while atomizer is running - disrupts drying process and may cause injury
- First-Time Use: Perform test run with water or simple sample (e.g., saline solution) to familiarize with operation
- Manual Retention: Retain this manual for future maintenance and troubleshooting
- Normal Operation: Slight powder adhesion to chamber walls (wall hanging) is normal in compact laboratory-scale dryers
- Cleaning Protocol: After wet and chemical cleaning, disinfect equipment at high temperature for 15-30 minutes. Avoid chlorine compounds for cleaning
Side-mounted 304 stainless steel cyclone separator and collection bottle create complete inert environment for sample recovery. Rust-resistant construction with smooth, non-stick surface ensures maximum sample purity and thorough cleaning to prevent cross-contamination.
Innovative cleanable observation window with external handle activation. Internal silicone wiper clears condensation and residue instantly without interrupting experiments, enabling real-time monitoring of drying process.
304 stainless steel waste collection vessel at base for centralized handling of cleaning waste and spills. Corrosion-resistant and easy-to-clean properties ensure longevity and prevent secondary contamination.
Built-in high-pressure vortex blower generates consistent air stream for thorough mixing of atomized droplets with hot air. Optimized airflow design ensures smooth powder conveyance and effective separation.
Precision peristaltic pump with continuously adjustable speed for consistent feed rate control. Food-grade silicone tubing with tool-free quick-change replacement prevents cross-contamination between samples.
Top-mounted observation light illuminates drying chamber for clear real-time monitoring of atomization and drying process. Enables precise parameter adjustments and full experimental control.
Professionally designed rear ventilation grille rapidly exhausts heat from electrical components. Active cooling prevents performance throttling and ensures stability during extended operation.
Scientifically centralized top panel groups water inlet/outlet connections with material feed inlet. Well-marked ports prevent misconnection and simplify setup for enhanced lab efficiency.
Four robust rubber casters with two locking brakes provide effortless mobility and absolute stability during high-speed operation. Rubber material offers vibration damping and floor protection.
- Ultra-Fast Drying: Centrifugal atomization technology transforms liquids into fine powder within 1-1.5 seconds, preserving heat-sensitive component activity
- Food-Grade Safety: All product contact parts constructed from stainless steel, complying with food-grade safety standards for sample purity
- Intelligent Temperature Control: Wide adjustable inlet temperature range (30~300°C) with ±1°C accuracy for reproducible results
- Compact Design: Optimized structure with small footprint delivers powerful spray-drying performance in limited laboratory spaces
- Easy Operation & Maintenance: Modular design allows easy disassembly and cleaning with integrated control panel for enhanced usability
- Check all pipes are properly connected and 220V wiring meets requirements. Verify all pipelines are connected and clamps tightened
- Prepare large bucket of water, place circulating water pump in bucket, and power on circulating water pump first. Ensure return water flow
- Connect two cooling water pipes above centrifugal nozzle with cooling water to cool the centrifugal nozzle
- Connect peristaltic pump feed pipe to centrifugal nozzle, then power on the system
- After powering on, turn on fan before heating. When inlet air temperature reaches set temperature and outlet temperature stabilizes (approximately 30 minutes), turn on atomizer
- Turn on atomizer (ensure circulating water pump return pipe has backwater), then turn on peristaltic pump to feed sample
- Begin drying process. Set temperature according to requirements. When sample is finished, turn off peristaltic pump, then atomizer, then heating. Turn off induced draft fan when temperature drops below 50 degrees
