Micro Mist Spray Dryers for Laboratory Use

What is the Micro Mist Spray Dryer?

  • A spray dryer is a device that uses hot air to instantly dry an atomized droplet to create a fine powder.
  • The atomized droplet is called a spray if the diameter is over 10µm, and a mist if the diameter is below 10µm.
  • Our innovative Micro Mist Spray Dryer features our Four-Fluid Nozzle that atomizes liquids into mists to be turned to powder.

The MDL Series features several models to best match your specifications. Transform liquids to fine powder for a wide range of applications.

  • Advanced capabilities: Even a very small specimen can be spray dried into a fine powder
  • Convenient monitoring: Glass viewing chamber for checking drying status
  • Simplified assembly, disassembly, and cleaning processes
  • Advanced centralized touch panel control
  • High-capacity production: Allows for large-scale production of an incredibly fine powder (only a few microns in size)
  • Streamlined processing: Only a short residence time inside the equipment is necessary,
    and with this finer product the equipment structure can be smaller
  • Good heat efficiency by utilizing the low temperature exhaust
  • Greater production efficiency: Eliminates the need for extra steps / processes like pulverizing and classifying
  • Superior Drying: Effectively and thoroughly dries previously difficult liquids
  • Low temperature drying: Great for pharmaceutical and food industries and protecting against denaturation
  • Adjustable design: Structured to easily transition from research to production level

Basic Specifications:

  • Water evaporation capacity: 3Kg/h
  • Atomizing method: four-fluid nozzle, straight edge
  • Drying method: Upper part hot air co-current type
  • Exhaust fan: inverter controlled, maximum 1.5m3/min
  • Hot air generator: electric heater 4kw
  • Hot air temperature: 40°C to 200°C, temperature control accuracy of ±1°C
  • Solution transportation pump: Roller Pump, maximum 50ml/min
