Spray Drying Optimization

Reduce your energy consumption, minimize clogging, and improve the quality of your milk powders with intelligent control for your spray drying towers.

By combining spray dryer modeling with dynamic AI-driven control, you shift from reactive to predictive management. Purecontrol anticipates deviations and adjusts setpoints to exactly what is needed, preventing over-processing and stabilizing moisture levels.

Real-time control of spray drying towers

Our technology automatically adjusts the operation of the drying tower to improve overall process performance:

Continuous regulation of critical parameters (temperature, humidity, pressure)
Anticipation of deviations to prevent blockages (temperature difference < 6°C)
Reduced energy consumption for drying

Objective:
Reduce energy costs, stabilize powder quality, and improve production reliability

Limit humidity fluctuations

Purecontrol anticipates changes in external parameters affecting the process (weather, ambient humidity, solar production, etc.) with a 12-hour forecast.

This advanced visibility allows the drying process to be adapted to stabilize the powder's moisture content, even under changing conditions.

Fewer fluctuations, a more stable final moisture level.

Preventing excessive powder drying

By stabilizing drying conditions and incorporating cycle history, Purecontrol prevents unnecessary overheating.

The result: more consistent powder quality and a significant reduction in energy losses due to over-processing.

Conforming powder without excessive energy consumption

Minimizing blockages at the exit of the lathe

This solution anticipates the risk of blockages by predicting powder temperatures at the lathe exit.

By maintaining the temperature difference within acceptable limits, it ensures reliable process operation and reduces unexpected downtime.

Fewer downtimes, smoother drying

Predictive and intelligent drying control

Purecontrol continuously analyzes key parameters of the spray drying process: air temperature, residual humidity, powder flow, pressure, and ambient conditions. Based on this data, our model accurately reconstructs the drying tower's behavior.
The solution anticipates temperature and humidity variations, adjusts operating parameters in real time, and ensures controlled drying. The result: consistent powder quality, fewer blockages, and significant energy savings.
