A salt-containing unprocessed foodstuff is charged in a wrapping tube unit comprising a cylindrical body, end plate means comprising members bonded to open opposite ends of the cylindrical body, and a pair of electrical contact members previously impregnated with a salt solution and fitted in the end plate means to provide a wrapped material foodstuff. The end plate means may be of any shape and is formed with a multitude of apertures, at least one of the members having cuts made therein to permit charging of the unprocessed foodstuff in the cylindrical body which may be deformed to conform to the shape of the end plate means. The apparatus for producing a wrapped food comprises a container in which the wrapped material foodstuff is placed and which is mounted on a carriage adapted to move in a reciprocating motion longitudinally of the apparatus, and a pair of electrode plates supported by guide rods disposed adjacent open opposite ends of the container and adapted to move in such a manner that, when the carriage moves in a reciprocating motion, the electrode plates also move in the same direction in a manner to be brought into and out of pressure engagement with recessed ends of the wrapped material foodstuff in the container to enable a current to be conducted through the unprocessed foodstuff to ripen it by the effect of Joule heat generated therein to produce a processed wrapped food. A sealing member may be applied to each end of the wrapped material foodstuff, before or after the conduction of the current, to enable the food to be preserved in cold storage.
A method for the production of a wrapped food, comprising the steps of inserting end plate means of any shape as desired in open opposite end portions of a wrapping tube made of an electrically insulating material and bonding the end plate means to the wrapping tube to provide a unitary structure, the wrapping tube conforming to the shape of the end plate means, said end plate means each comprising a member having a flat surface portion substantially perpendicular to the length of the tube and having formed therein a multitude of apertures and a protruding edge portion formed integrally with and disposed at right angles to said flat surface portion and directed to the respective open end of the tube;
A foodstuff wrapping tube unit comrising an electrically insulating wrapping tube filled with unprocessed foodstuff and comprising a cylindrical body and end plate means bonded to open opposite end portions of said cylindrical body, said end plate means each comprising a member having a flat surface portion formed with apertures therein and a protruding edge portion formed integrally with and disposed at right angles to said flat surface portion and directed to the respective open end portion of the tube, a pair of moisture absorbing electrical contact members previously impregnated with a salt solution and fitted into surface contact with the flat surface of said end plate means and a pair of sealing members detachably applied to the outer surface of said electrical contact members to provide a seal to said wrapping tube.
