CIP and innovative cleaning techniques

Burggraaf & Partners has developed a two-day Cleaning in Place course for producers and machine builders in Food, Feed and Pharma. All new automatic cleaning systems are discussed here. Not only pipes and tanks, but also the automatic cleaning of open systems such as conveyor belts, filling machines and other equipment. Robot-CIP or r-CIP is the future. This not only allows you to save on total cleaning costs (and down-time), but it is also the only way to guarantee that you can start with clean equipment.

Companies affiliated with OOM may be eligible for a contribution to the costs. For more information, see www.oom.nl.
