The source is connected to shaped electrodes, the shaping of the electrodes and their spacing from the food product being selected in dependence upon the configuration and irradiation required of the product being treated. The food product may be a pre-cooked meal comprising a plurality of constituents and the electrode is then shaped to take into account the geometry of the different constituents and in combination with the spacing of the electrode from the product, takes the heating requirements of the individual components into account.Field of SearchElectrode typeWith conveyor or movably supported Conveyor ELECTRIC, RADIANT OR VIBRATIONAL TREATING MEANS SUBJECTING FOOD TO AN ENCLOSED MODIFIED ATMOSPHERE With means to move food Non-rectilinear movement Circular movement of food support NON-COOKING HEAT TREATMENT OF FOOD TREATMENT OF PACKAGED PRODUCT BY ELECTRICAL OR WAVE ENERGY APPLICATION OF A GAS, MIST, SMOKE OR VAPOR TO A FOOD MATERIAL UNDER THE INFLUENCE OF ELECTRICAL OR WAVE ENERGY Heating by electromagnetic wave | |
