Description

Technical field

[0001] The present invention relates to a method for monitoring a spray dryer, which includes the steps of: setting a spray drying chamber; and associating one or more cameras with the spray drying chamber, the one or more cameras having a view inside the spray drying chamber field. In addition, the present invention relates to a spray dryer including a spray drying chamber, an atomizing device, and one or more cameras positioned to be associated with the spray drying chamber. Background technique

[0002] The spray drying method is a well-known method for turning liquid products into powder products. The drying method takes place in a drying chamber where the dry air is combined with a supply (ie, atomized into droplets) provided by one or more nozzles or other shaped parts of an atomizer (such as a rotary atomizer) Liquid) contact. Dry air enters the drying chamber through an air diffuser positioned at or near the top of the drying chamber. Another drying de...
