Dew point monitoring during the pneumatic conveying of powdery materials

Hygroscopic materials absorb moisture from the ambient air. The formation of water can cause the material to stick together and, in the worst case, block the pipe. Particularly when pneumatically conveying powdery, hygroscopic substances such as baking powder, sugar, soup powder, active pharmaceutical ingredients, etc., it is important to ensure that the compressed air (conveying air) has a low dew point value.
