CO detection in spray drying

The safety of powder drying has become increasingly important for manufacturers operating in the food and pharmaceutical industries. The outbreak of fire is a significant risk in these factories, potentially causing serious damage. Manufacturers must balance the need to improve efficiency with keeping their operations continuous, cost-effective and, most importantly, safe.

CO detection system

CO detection is widely used for pre-warning in dryer installation safety systems. Uncontrolled process conditions can cause the product to coagulate and form lumps, which poses a major risk to the dryer’s operation and shortens production cycles between cleaning. Importantly, coagulated products are exposed to increased residence times, which can cause degenerating smoldering reactions, creating a significant risk of fire and explosion.

NICOSYS-3 is a sample conditioning system, that detects CO in gaseous streams. We began developing this system 25 years ago, with NIZO (Dutch National Institute of Dairy Research). The Hobré NICOSYS-3 is the latest version of the system, with condensate coolers, NDIR gas filter correlation analyzer, and sample probes for various applications. The CO detector improves process safety with fast and accurate detection of smoldering and Maillard reactions to reduce fire risk.
