Abstract
The invention relates to a method for the heat treatment of meat products in a feeding element (4) by means of high-frequency electromagnetic waves, and an apparatus for the execution of the method. The invention also relates to an advantageous application of an apparatus according to the invention. The object of the invention is to increase the depth of penetration of the electromagnetic waves in a product which is to be heated or boiled, where the electrodes (2, 3; 20, 22) are external and placed on the outside of the feeding element (4). The object is achieved by placing a product electrode (15) in the feeding element (4), in that said product electrode (15) serves as a short-circuiting element and is of a material having an electrical conductivity which is better than that of the product that is required to be heat treated.
