Current operating point
Spray dryer digital twin
Live operating window for a drying process.
Adjust feed, air, atomization, chamber, and formulation assumptions. The twin estimates outlet temperature, powder moisture, droplet size, glass-transition margin, and sticky-zone risk.

Stickiness curve
Tg falls as water plasticizes the solids. Sticky behavior is flagged above Tg plus offset.
