Cleaning In Place

When the development in the Dairy Industry took off in the sixties with bigger and bigger Dairies it was not possible to use open tanks or tanks with detachable lids one could clean manually.

The next step was a turbine inside the top of a tank and a three-way valve, enabling detergent to circulate over the Pasteuriser.

This was progress, but not for very long as a lot of detergents was wasted and the Pasteuriser was in-active for what it should have done

Then a clever guy come up with the idea of Cleaning In Place — A separate Unit with tanks, Heat Exchanger, Pumps & automatic programs, At the same time, they could reuse the detergent and save the environment from a lot of aggressive wastewater.
