Product Description
Detailed Specifications & Features
Pressure Spray Dryer EcoGuard Series
The Pressure Spray Dryer EcoGuard Series is designed for producers of detergent, dye and ceramic powders who must minimize fugitive dust, document energy performance and meet dust explosion safety codes under environmental and workplace regulations.
Working Principle
Filtered liquid feed is pressurized to 2 to 20 MPa by a high-pressure pump and atomized into a conical liquid sheet through a pressure nozzle, breaking into droplets that contact filtered, heated hot air in the drying tower (co-current, counter-current or mixed-flow configurations available). Moisture evaporates rapidly, drying into solid particles collected at the tower bottom and by a cyclone separator, with exhaust routed through the compliance emission train.
Environmental, Safety & Energy-Efficiency Enhancements
- Low-dust product design: larger, denser particles (100 to 300 μm) inherently generate less airborne dust than fine centrifugal spray powders, reducing occupational exposure and downstream dedusting load;
- Exhaust heat recovery: optional heat exchanger recovers exhaust energy to preheat drying air, lowering fuel/electricity consumption per ton of product;
- ATEX/explosion-proof configuration: available for combustible detergent and organic powders with ATEX Zone 20/21/22-rated instrumentation, inerting and explosion venting;
- Emission control: cyclone + bag filter exhaust train meets EU/North American particulate emission limits;
- Energy monitoring: standard metering of high-pressure pump and heater power with ISO 50001-compatible data logging;
- Full CE documentation and third-party emission/noise test reports available for regulatory submission.
Technical Advantages
- Larger, denser, free-flowing particles with low dust generation;
- Simple, easily maintained nozzle structure suitable for abrasive feeds;
- Precise control of particle size and bulk density via nozzle pressure, orifice diameter and swirl core;
- Large-scale continuous production with lower power consumption than centrifugal atomization;
- Documented energy recovery and safety compliance reduce permitting risk.
Applications
Suitable for detergent, washing powder, dye, pigment and ceramic powder manufacturers in Europe and North America where occupational dust exposure limits, energy efficiency disclosure and dust explosion protection are required for spray drying operations.
