PIGNAT Spray Dryer – ATM2000

SKU: ATM2000 Category: Tags: , ,


Study spray drying:


  • The process entails continuously drying the droplets sprayed into an atmosphere of hot gases.
  • The solids in suspension or in solution in the droplets are simultaneously dried and formed. In many cases forming is either the primary or secondary aim of the operation.


  • Improve the pour-ability of a powder (by obtaining spherical agglomerates).
  • Protect by micro encapsulation.
  • Make a soluble body “instant” (in a form which can redissolve quickly).


  • Maximum hot air temperature of 200 C
  • Saturated solution injection rate from 0 to 1.5 L/h

Proposed experiments:

Manufacturing of powdered milk:

  • Spray drying of milk
  • Characteristics of the solid
    • Influence of air preheating.
    • Influence of injection temperature.
    • Influence in injection rate.
    • Influence of the temperature in the preparation of solutions (option O2).
  • Material balance.
  • Finding the operating limits of the unit for this application.
