Dairygold in France uses a spray dryer to produce fine powders as an end product from milk and cheese. The air coming from the spray dryer contains a lot of odours. Especially some mature cheese products cause a strong smell, leading to complaints from the neighbourhood.
Spray dryer odour control
Aerox carried out pilot tests on-site on different cheese products. The test results were very convincing. Based on the promising results, Dairygold ordered an Aerox-Injector in 2010 to treat the total airflow of 20,000 m3/h coming from the spray dryer.
Treating hot airflows
The Aerox-Injector is suitable for all temperature and humidity ranges. Therefore, the 70 - 90°C process air is treated without any changes or additions to the process ducts. Dairygold is very satisfied with the odour control results of the Aerox-Injector.
