Fire Protection Solutions for Milk Powder Spray Dryers
One of the main risks in a spray dryer is material build-up inside the dryer. Over time, this material will over-dry and can start to smolder. If this smoldering fire continues without detection, a fire can break out.
Many milk products will self-ignite at 100˚C over time, if the build-up thickness is around 100-150mm. This is very critical since all dryers have an inlet temperature of more than 100˚C. Another risk is mechanical friction in any of the mechanical moving parts in the area of the spray dryer.
Firefly’s solution for the protection of milk powder spray dryers consists of a combination of the Firefly Quick Suppression System and Spark Detection System, using flame detection and suppression as well as spark and hot particle detection and extinguishing. Firefly also offers a fire protection solution for the fluid bed, minimizing the risk for a fire in the fluid bed and downstream the production flow.
