Viscosity-controlled processing of a liquid foodstuff

摘要

Controlling or regulating the processing of a liquid food product, comprises (a) providing data that is obtained by a mathematical modeling depending on the viscosity of liquid food products of the shear rate, (b) measuring the viscosity of the liquid food product to be processed at a predetermined shear rate at one measuring point, and (c) controlling or regulating the processing of the liquid food product to a working device that is downstream of the measuring point in reaction to the viscosity measured at the measuring point and based on of the data. Independent claims are also included for: (1) a controlling or a regulating device for a system for processing a liquid food product, comprising a data storage unit for storing the data obtained from mathematical modeling dependence on the viscosity of the liquid food product on the shear rate, and a control unit for controlling or regulating the processing of the liquid food product, where the viscosity of the food product to be processed, based on the stored data, is measured in response to a shear rate predetermined at a measuring point, which is downstream to a working device; (2) processing device for processing a liquid food product, comprising the measuring point for measuring the viscosity of the liquid food product at a predetermined shear rate of the liquid food product, the working device for processing the liquid food product, where the working device is provided downstream of the measuring point, and the above mentioned controlling or regulating device; and (3) determining the viscosity of the liquid food product in the working device, comprising (i) providing the data, which is obtained by mathematical modeling of the liquid food products depending on the shear rate of the viscosity of the liquid food products, (ii) measuring the viscosity of the liquid food product at a predetermined shear rate of the liquid food product at a measuring point, and (iii) determining the viscosity of the liquid food product at a second shear rate of the liquid food product, which is different from the predetermined shear rate, based on the stored data.
