160-200°C Inlet Seting Temp High Speed Centrifugal Spray Dryer For Sweet Whey Powder
Product Description:
The ideal temperature settings for spray drying sweet whey powder are typically:
Inlet Temperature: Around 160-200°C (320-392°F)
Outlet Temperature: Around 70-90°C (158-194°F)
Considerations
Inlet Temperature: High enough for efficient drying but not so high as to degrade proteins or flavors.
Outlet Temperature: Ensures moisture is adequately removed while maintaining product quality.
These settings can vary based on specific equipment and desired product characteristics. Adjustments may be needed for optimal results.
Common challenges in the spray drying process include:
- Clogging:
Nozzle blockages due to solid buildup.
Requires regular maintenance and cleaning.
- Inconsistent Particle Size:
Variability in atomization can lead to uneven drying.
Affects product quality and performance.
- Heat Sensitivity:
High temperatures can degrade sensitive components.
Requires precise temperature control.
- Powder Stickiness:
High sugar or fat content can cause sticking to chamber walls.
May need additives or surface modifications.
- Energy Consumption:
Spray drying is energy-intensive.
Optimizing parameters can reduce costs.
- Hygiene and Contamination:
Ensuring cleanliness to prevent contamination.
Regular cleaning protocols are essential.
Features:
- Extended Shelf Life: Reduces moisture content to prevent spoilage.
- Convenience: Easier storage and transport.
- Consistent Quality: Uniform particle size and texture.

Process overview:
Process Overview
- Feed Preparation:
Whey is pre-concentrated using evaporation to reduce moisture.
- Atomization:
The concentrated whey is sprayed into a hot air chamber, forming fine droplets.
- Drying:
Rapid evaporation of moisture occurs, leaving behind dry whey particles.
- Collection:
The powder is collected and cooled for packaging.
