Our Solutions

Convective Dryers

• Use hot air or gas to evaporate moisture from materials.
• Key Features:
  • High throughput.
  • Suitable for bulk materials.
• Types:
  • Rotary Dryers: Cylindrical drums that tumble materials for
    uniform drying.
  • Fluidized Bed Dryers: Airflow suspends particles for efficient
    heat transfer.
  • Belt Dryers: Conveyor belts move materials through heated
    chambers.

Conductive Dryers

• Use direct contact with a heated surface to transfer heat to materials.
• Key Features:
  • Efficient energy use.
  • Ideal for sticky or viscous materials.
• Types:
  • Drum Dryers: Rotating drums with heated surfaces for thin
    layer drying.
  • Tray Dryers: Materials spread on heated trays in a controlled
    environment.

Vacuum Dryers

• Operate under low pressure to reduce the boiling point of moisture,
  enabling drying at lower temperatures.
• Key Features:
  • Gentle drying for heat-sensitive materials.
  • Preserves material quality.
• Types:
  • Vacuum Tray Dryers: Multiple trays for batch operations.
  • Rotary Vacuum Dryers: Tumbling action for uniform drying.

Spray Dryers

• Convert liquids into dry powders by spraying them into a hot air
  stream.
• Key Features:
  • High-speed drying.
  • Produces uniform particle sizes.

Freeze Dryers (Lyophilizers)

• Remove moisture by freezing the material and then sublimating ice
  under vacuum.
• Key Features:
  • Preserves material structure and nutrients.
  • Ideal for sensitive or high-value products.

Infrared Dryers

• Use infrared radiation to heat and evaporate moisture.
• Key Features:
  • Rapid and energy-efficient drying.
  • Targeted heating for specific areas.

Microwave Dryers

• Use microwave energy to heat materials internally for uniform drying.
• Key Features:
  • Quick and efficient.
  • Reduces drying times significantly.

Hybrid Drying Systems

• Combine multiple drying techniques for optimal results.
• Key Features:
  • Adaptable to various materials and moisture levels.
  • Improved energy efficiency.

Applications of Drying Systems

• Food and Beverage
  • Removing moisture to extend shelf life and preserve nutrients.
  • Example: Freeze dryers preserving the structure and flavor of freeze-dried fruits.

• Pharmaceuticals
  • Drying active ingredients and formulations without compromising quality.
  • Example: Vacuum tray dryers gently drying heat-sensitive drugs.

• Chemical Industry
  • Preparing powders, granules, or liquids for further processing.
  • Example: Spray dryers producing fine chemical powders from liquid solutions.

• Textiles
  • Removing water from fabrics during production processes.
  • Example: Infrared dryers rapidly drying dyed fabrics.

• Recycling
  • Drying recycled materials like plastics or paper for reuse.
  • Example: Rotary dryers evaporating residual moisture in shredded plastic.

• Energy Sector
  • Removing moisture from biofuels or coal for efficient combustion.
  • Example: Fluidized bed dryers processing biomass for energy generation.
