  • Patent number: 7520667
    Abstract: The present invention relates to a method and a system for determining a set of process parameters of a treatment unit in which unit a product is subjected to a temperature treatment, the method comprising: subjecting a product to an electromagnetic signal before, during and/or after a temperature treatment, wherein said electromagnetic signal is adapted to interact with said product dependent upon the dielectric constant distribution of said product, receiving an electromagnetic signal which has interacted with said product, analysing the received electromagnetic signal in comparison with the transmitted electromagnetic signal and thereby determining a response being dependent upon the dielectric constant distribution of said product and based thereupon determine the temperature (distribution) or water content of the product, and analysing said temperature distribution or temperature of the product or products and based thereupon determining a set of process parameters for a temperature treatment in a treatm

  • Patent number: 6238196
    Abstract: An apparatus for molding food products of a moldable food material having a molding compartment, a feeding device for feeding the food material to the molding compartment and a molding plate with a mold cavity. The molding plate is moveable between a forwarding position in which the mold cavity communicates with the molding compartment via a molding opening, and an ejection position, in which the mold cavity is open towards a base. A plunger assembly fills the mold cavity with the food material from the molding compartment via the mold opening, and a piston ejects a food product molded in the mold cavity from the molding plate in the ejection position. A common, programmable control unit predetermines the periodical movements of the feeding device, the plunger assembly and the molding plate as a function of time in the form of separate movement patterns.
