Control of the milk pasteurizer for small dairy operation

in

staedler automation AG designed, developed and commissioned the control for a small dairy operation.

This plant pasteurizes and homogenizes raw milk. The processed milk is processed further into yogurt or bottled directly as whole milk.

A fully automatic CIP station is controlled in addition to the pasteurization system. The process refrigeration plant and hot water preparation are also controlled by a central control unit.

The Siemens control unit controls all processes relevant for production. The operator has a single operating panel that controls all processes in a well-structured setup.
