Spray drying whey protein presents unique challenges that generic dryers cannot adequately address:

• Thermal Sensitivity: Excessive heat can denature proteins, destroying their biological activity and functional properties.

• Stickiness & Hygroscopicity: Whey is notoriously sticky and moisture-absorbing, leading to wall deposition and product loss inside the chamber.

• Stringent Hygiene Requirements: Full compliance with food safety standards (like FDA, EHEDG) is non-negotiable.

• Demand for High Solubility: The final powder must be instantly soluble, requiring precise control over particle size and density.

• Cost of Waste: Given the high value of whey protein, maximizing yield is essential for profitability.
