Superior Hygiene & Safety (Infant formula)


HOCHDORF Group is one of the biggest milk processors in Switzerland, processing 300 million kilograms of fresh milk each year. Their Sulgen plant was experiencing issues with the hoseclamp connections between processing equipment frequently leaking powder into the factory. They were also untidy and the hose-clips were sharp, causing holes in the connector sleeves themselves and presenting an injury risk to fingers during changeovers. As part of their continuous improvement process, HOCHDORF turned to BFM® fitting to clean up their processing system, and make their changeovers much faster and safer for staff. 

Below shows the variety of locations, sizes and locations BFM® fittings have been installed in at the HOCHDORF plant, which now is clean and dust free.

The Challenge

There were problems with milk powder leakage and build-up around the clamped connections, as well as issues with the sharp-edged pipe clamps leaving small cracks or holes in the flexible hoses. 

The dust leakage was a serious hygiene concern, and the frequent connector changes required due to the damage caused by the hoseclamps (in addition to CIP) meant staff risked injury when manipulating them during replacement.

The time required for this replacement, and constant clean-ups also meant valuable production time was being lost.


The Solution

After a successful initial trial, all connectors on one of Hochdorf’s spray-drying tower lines were replaced with the BFM® fitting

There were more than 60 different positions requiring replacement and local Distributor Swissfilter worked with the team to ensure all locations were correctly fitted with the best connector for the job.

Now there is no leakage, far less changeovers are required, and when they do need to remove a connector, it is a fast, safe and easy operation. Hochdorf have recently commissioned a brand new spray line with BFM® fittings already installed.

The Benefits
