NIZO food research has assisted United Dairy Men of Arizona (UDA) with improving their drying process. Based on NIZO’s models (Premia) to predict product-process interactions and on a joint review of the process by NIZO and UDA, improved set points could be determined resulting in reduced powder build-up, extended runtimes and thus reduced costs at a higher output.
When Phoenix-based UDA experienced reduced run times caused by powder build-up in their spray dryer, they commissioned NIZO food research to do a scan of their process.
NIZO has 65 years of experience in optimizing spray drying processes and developed its Premia software platform to model process-product interactions. This software was used to evaluate and predict product properties based on settings and conditions such as inlet air humidity and temperature, feed, and outlet air properties.
As a result of the process scan, the cause of powder build-up could be determined and alternative settings were determined resulting in the best conditions for a quality product with minimal powder build-up.
According to Keith Murfield, CEO of UDA, the reduced cleaning times allow an increased output of high quality powder at reduced costs.
