In a bottle or can filling plant, the beverage should be chilled to an appropriate temperature. A plate heat exchanger is usually applied to do the cooling. In the current plants, the coolant is supplied from two coolant tanks, a high temperature tank and a low temperature one. We propose a new cooling method, which does not require those tanks. The coolant is supplied from the refrigeration unit directly to the plate heat exchanger. The flow of it is controlled, so that the temperature of the beverage at the outlet of the heat exchanger becomes the designated one. A bypass valve is used to control the flow of coolant. In order to improve the response and precision of the control, an observer and a regulator are introduced. Through simulations and experiments at a real plant, we can conclude that our proposed method can be utilized in actual filling plants.
