Powder recovery from spray dryer exhaust systems for food and dairy products has in the past typically been done in cyclones, either alone, where environmental issues have not been in focus, or, where stricter requirements are enforced by the authorities, cyclones combined with wet scrubbers or textile bag filters. Based on almost 10 years of research, development and testing of a CIP-able bag filter by GEA Niro, the SANICIP™ filter has now reached a point where it is setting the standard for almost all powder dryers.
