Gea redesigns its Sanicip bag filter for spray dryers

GEA has made a series of significant changes to its trusted Sanicip bag filtration system for food and dairy spray dryers in a long-term development project that claims to offer valuable operational benefits to users of the new equipment. The new Sanicip II (patent pending) maintains and controls the pressure drop through the filtration bags more effectively by promoting longer production times and reducing CIP intervals, says Gea. Combined with other advances, such as easier maintenance and better space utilization than its predecessor, bag life is now up to 50% longer. These developments add to the more reliable operation, financial savings, and a better working environment for operators. Following extensive studies with customers, Gea identified key areas where design modifications could be made in this new generation of Sanicip technology. Using the latest computational fluid dynamics (CFD) techniques to optimize airflow within the filter, Gea said that it was able to reduce the length of the filter bags from up to 7 meters to just 4.5 meters and, by reducing the diameter and increasing the…
