GEA No Intervention Fines Return System (FRS)

GEA’s No Intervention Fines Return System (FRS) is designed to automate the cleaning-in-place (CIP) processes for dairy and food powder producers’ spray dryer fines return systems.

In spray dryers, powder fines are often separated from the exhaust air via cyclones and bag filters. A fines return system returns the fines to the drying process, either for agglomeration or integration with the final powder outlet.

Typically, cleaning cyclones and fines return systems first requires opening and dismantling the fines return system from the cyclones outlet. After cleaning, both must be reconnected again, which increases the risk of recontamination as well as the potential for mistakes in reassembly.

Designed for food and dairy spray dryers, the FRS uses valves to create a smoother and fully automated CIP process, which negates disassembly before and after cleaning. All connections within the fines return system remain closed and once cleaned, can directly be used for production. The valves were developed to comply with hygienic design criteria of the European Hygienic Engineering and Design Group (EHEDG).
