Abstract: A method is implemented on a computer device to configure a control device for closed-loop control of a sub-system in a plant for production of food products. The computer device obtains definition data, DD, which indicates a task performed by the sub-system in the production of food products and equipment in the sub-system for performing the task; derives a candidate process model, CPM, of the sub-system based on DD; obtains measurement data, MD, generated by the sub-system when operated in accordance with a test sequence, TS; estimates constant parameter(s) of differential equation(s) in the CPM based on TS and MD; defines a final process model, APM, for the sub-system based on the differential equation(s) and the constant parameter(s); and operates a tuning algorithm on APM to determine control parameter(s) of the control device for closed-loop control.

Abstract: A system for processing a liquid or semi-liquid food product is provided. The food product is a composition of a first sub-composition having a low concentration, such as water or a sugar solution, and a second sub-composition having a high concentration, such as a concentrate. The high concentration is greater than the low concentration. The system comprises an ultra violet (UV) light treatment apparatus for reducing an amount of microorganisms in the first sub-composition and a blending apparatus for aseptically combining the first sub-composition and the second sub-composition into the liquid or semi-liquid food product.

Abstract: A system, method and computer-readable medium for producing a pasteurized liquid product. The system comprises a first supply comprising a concentrate having a water content being less than that of the desired liquid product; a second supply of water and/or sugar solution; a first heat treatment device connected to the second supply and being arranged to heat the water or sugar solution to a predetermined temperature for reducing a number of microorganisms in the water or sugar solution; at least one combiner connecting the first supply with the heat treatment device, and configured to combine the heated water or sugar solution with the concentrate to form a liquid product, wherein the predetermined temperature of the water or sugar solution is set such as to reduce a number of microorganisms of the liquid product by the heat energy of the heated water and/or sugar solution.
