The SPRAYEYE® IR camera system (patented) is designed to monitor the temperature of spray nozzles in modern spray dryers and warn operators in case of trouble. The IR cameras are located in the spray dryer’s air disperser and, in combination with a visual monitoring system, offer an extra level of safety.
Infrared temperature monitoring for improved safety
A conventional visual system is used to monitor spray dispersal, identify nozzle leaks and help operators to detect product build-up on the spray nozzles. The IR camera system provides continuous temperature monitoring and heat variation images from each nozzle to highlight product build-ups that may begin to smolder.
Offering both continuous real-time temperature visualization and automatic temperature surveillance, the SPRAYEYE® IR early warning system helps to prevent fires and explosions in the dryer by detecting hazardous temperature increases and hot spots.
The prewarning system indicates high temperatures in several ways:
Most fires are started as a result of unnoticed temperature changes in the drying chamber. SPRAYEYE® IR temperature scanning technology delivers the following benefits:
Like the SPRAYEYE® Visual, the SPRAYEYE® IR cameras are not clean-in-place (CIP) compatible and must be removed from the process before cleaning is initiated. The IR cameras will shut down at 48 °C and may be permanently damaged if temperatures reach more than 60 °C. Adequate cooling of the cameras is critical; this is achieved with a combination of razor air/air disperser air in front of the lens and an internal flow of cooled compressed air.
The SPRAYEYE® IR is equipped with a power loss safety function and a lens integrity monitoring system, as well as a “watchdog” mode that provides a continuous functionality check for high reliability.
The SPRAYEYE® IR system provides a prewarning alert before abnormal carbon monoxide levels can be detected, and the ability to identify the exact position, temperature and size of problem enables operators to react effectively.
The integrated management of alarm levels, definition of areas for automatic monitoring, camera protection systems and simple calibration helps to ensure a higher level of fire and explosion risk management.
The SPRAYEYE® IR enables operation with increased inlet air temperature at a reduced risk, and some customers have been able to retain their standard operating conditions when moving to a more flammable recipe.
Zelfs de kleinste afwijking in kwaliteit en consistentie tijdens het droogproces kan tot problemen, afgekeurde producten of verloren productietijd leiden.
Een eenvoudige, compacte, hygiënisch ontworpen digitale camera voor procesbewaking op afstand in uw zuivelpoederverwerkingsapparatuur.
De meest voorkomende, kostbare en tijdrovende problemen tijdens het sproeidrogen treden op bij de nozzle. Storingen door lekken, verstoppingen, productafzettingen en ongelijkmatig sproeien kunnen leiden tot dure stilstandtijd tijdens het bedrijf, en mogelijke schade.
De gepatenteerde VISIOCOVER® is een transparant sanitair deksel dat toegang biedt tot procesapparatuur en visuele inspectie mogelijk maakt. Hij is gebaseerd op het beproefde hygiënische ontwerp van GEA’s SANICOVER®, gemakkelijk te gebruiken en conform EHEDG-richtlijnen.
