CIP - Innovative cleaning techniques (Dutch)

It covers all new automatic cleaning systems, not only pipes and tanks, but also automatic cleaning of open systems such as conveyor belts, filling machines or other equipment. Robot-CIP or r-CIP is the future. In this way you can not only save on the total cleaning costs (and down-time), but it is also the only way to guarantee that you can start with clean equipment.

Experienced trainer

Burggraaf & Partners has been specialized since 1993 in advising the food industry and pharmacy, and machine builders in this area. In practically all sectors (bakery, fruit and vegetables, dairy, meat, beverages, biotechnology), the agency is active and together with various organisations it has provided dozens of training courses in this area.
