Abstract

<PICT:0610520/III/1> <PICT:0610520/III/2> <PICT:0610520/III/3> For uniformity in the electrostatic heating of food products in containers of material having a high dielectric constant, e.g. glass, ceramic, plastic, the filled containers are immersed in a bath of liquid or sand having a high dielectric constant and the combined bath and immersed containers are subjected to the high-frequency electrostatic field. Trays 2 of electrically non-conductive material, in which are jars 1 of food resting on bosses 20 in the base of the tray and surrounded by water, other liquid of high dielectric constant, or sand, are carried on a belt 4 of canvas or glass fabric between electrodes 5 and 6 connected to a high-frequency oscillatory generator G, the belt sliding over the electrode 6 and the spacing between the electrodes being adjustable by movement in a stationary bracket 12 of a threaded spindle 11 attached to the electrode 5. Alternatively, jars of food are carried on a belt 16 through an elongated tank 15 in which flows a liquid of high dielectric constant, the liquid entering and leaving by the inlet and outlet 18 and 19, and are, during their passage between electrodes 21 and 22 connected to a high-frequency oscillatory generator G1, submerged in the liquid, the belt carrying the jars being held down by engagement under idler rollers 17. The Specification as open to inspection under Sect. 91 comprises also immersion of the containers in any fluid bath having a high dielectric constant. This subject-matter does not appear in the Specification as accepted.
