Control system of dairy cooling process in Dairy Hlinsko

Mlekarna Hlinsko, s.r.o. (Dairy Hlinsko) is well-known producer of milk products in the Czech Republic. The dairy was founded in 1939 by Swiss company Nestlé S.A. The dairy company started with production of powdered milk, children's milk, buttermilk and sweetened condensed milk soon after its founding. The production continued till 1948. In early 1949 the company was nationalized by the state. Forty-four years later, four years after the Velvet Revolution in the Czech Republic, the dairy company was privatized again. Mlekarna Hlinsko, s.r.o. became the new owner and continues with production of well-established milk products to the present day.

The new Control System of dairy cooling technology was installed in 2004. A SCADA-based Control System was implemented by Czech company Energie MaR s.r.o. Control of all all systems is handled by one Landis RWP80 PLC device which is connected to the Control Computer in the Supervisory Room. The control computer with the Reliance SCADA system installed provides visualization and control of all cooling systems. The operators have perfect overview of all cooling system technology thanks to transparent visualizations created in Reliance. The system also provides saving of all necessary data for further analysis.
