<P>PROBLEM TO BE SOLVED: To provide a method for heating a packaged food product in view of the fact that a previously exposed method using electric heating has an advantage of heating in a short time but is not acceptable for a production site such as a factory because of making the shape of a package and the finish of a product extremely different from those produced by a conventional method using a smokehouse. <P>SOLUTION: This method for heating the packaged food comprises putting electrodes for electric heating and a food material in a packaging bag and sealing the product to form the packaged food. The electric heating is performed by electrical contact through pressure-welding a feeding part to the electrode in the packaged food from the outside of the packaged bag. When electrically heating the packaged food, heat is released from the surface of the packaged food. A temperature control part performs heat insulation and warming so as to prevent temperature drop by the heat radiation. When electrically heating the packaged food, generation of heat at the contact surface of the electrode with the food material becomes larger than that of other parts due to contact resistance at the contact surface. The temperature control part performs heat radiation or cooling so as to prevent excessive temperature rise by the generation of heat. <P>COPYRIGHT: (C)2004,JPO |
