JPS5655187A - Vessel for packed food - Google Patents

Abstract

PURPOSE: Electrically conductive plates are fitted to the whole inner surfaces of the both flat ends of a vessel composed of an outer cylinder and inner cylinder, both of which is slidably fitted, and fixed with electrically conductive rivets, further contact bodies containing an aqueous salt solution are fitted to the inner surfaces, whereby a food product is uniformly heat aged.

CONSTITUTION: The inner cylinder 2 is filled with a food product A and the outer cylinder 1 is fitted from the open end of the inner cylinder 1 thereto. Electrically conductive plates 3, 3' are tightly sticked to the whole surface of the inside of the both ends 1a, 2a and fixed to the end surfaces 1a, 2a with electrically conductive ribets 4, 4' at the center by caulking and further contact bodies containing an aqueous salt solution 5, 5' are fitted to the inner surfaces. The both end surfaces 1a, 2a of the vessel are pressed with the surfaces 6a, 6a of press 6, 6 so that the top ends of electrodes 7, 7 comes into contact with the outer heads of ribets 4, 4'. Therefore, when electricity is applied between electrodes 7 and 7, the current flows uniformly through the whole surface of the conductive plates 3, 3' and the food product A is heat aged by the Joule heat.
