Abstract
An apparatus is provided for uniformly and rapidly heating, pasteurizing and/or sterilizing food products which comprises a conveyor on which the food products are conveyed and a source of radio-frequency radiation which is directed at the food products. 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.
