Atomization / 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
- Injection nozzle diameter
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.
This unit is complete with an educational textbook presenting different experiments and theoretical reminders, functioning mode and experimental results.
- PE feeding flask, 2 L.
- Peristaltic pump with variable flow rate 0 to 1.1 L/h.
- Compressed air injection system: pressure reducing value with dial gauge, regulating valve. The air goes then through the cannula for liquid injection, stainless steel, jet of 0.5 mm. System is completely dismountable for ease of cleaning.
