Problem

In summer, when the moisture content of the ambient air is high, the operational conditions of the spray dryer are less favorable than in winter, when the ambient air contains little moisture. Using humid air in the spray drying process may cause product sticking inside the drying chamber resulting in dryer failure and plant downtime.
In a stable spray drying operation, the influence of weather fluctuations are eliminated allowing for high production capacity and a consistent, high quality powder. The end result is a more profitable spray drying operation.

Solution

With dehumidification, the air can be controlled at the same low moisture level year round. This ensures stable operational conditions with high production capacity throughout. Munters has developed a series of high-performance dehumidifiers making this possible.
