FLASH DRYERS
 

PRINCIPLE

Flash drying works on the principle of pneumatic transport using hot air. Wet product is introduced into a high velocity air stream through a special Venturi feeder. Highly turbulent airflow generates an intense gas-solid thermal exchange and disaggregates the product. This allows a rapid evaporation in a few seconds residence time. Rapid drying process avoids overheating of product allowing the use of high temperature drying gases. At dryer outlet, dried product is recovered by means of a gas-solid separator (cyclone, bag filter, etc.). Partial recycling of dried product in wet material can be considered in case of sticky product.
This process is particularly suitable for fine products or filter cakes.
 

ADVANTAGES OF THIS TECHNOLOGY

  • Low maintenance
  • Simple process
  • High thermal efficiency
  • Highly reactive process control
  • Short start-up and shut-down sequences
  • Reduced foot-print layout

MAIN APPLICATIONS:
Fine powders, filter cakes, fibers, sawdust, lightweight products for all industries (chemical, food, mineral, etc.).

MAIN PROCESSES:
Pre-drying, dehydration, drying.


PILOT TEST LABORATORY:
For determination of flash dryers parameters and possibility to perform semi industrial tests.


COMESSA CAN PROPOSE FOLLOWING ALTERNATIVES:

  • Rapid dryer
  • Cyclonic dryer
