  • Patent number: 4612199
    Abstract: A method of and an apparatus for producing processed foodstuffs by passing an electric current to foodstuff materials including a container of insulating material open at opposite sides for receiving a foodstuff material suitably permeated with a salt solution which is placed in the container and held between a pair of electrode members located at the opposite open sides of the container. An annular coil is arranged around the container. As electric currents are passed simultaneously through the annular coil and between the pair of electrode members, Joule heat is generated in the foodstuff material to thermally treat and sterilize the foodstuff material while lines of magnetic force are produced and applied to the foodstuff material in such a manner that an AC magnetic field exerts influences on the electric current flowing through the foodstuff material, to render substantially uniform the temperature distribution in the foodstuff material and increase the amount of inosinic acid or glutamic acid therein.

  • Patent number: 3986815
    Abstract: A burner wherein a fuel gasifying member is non-rotatably mounted in a main body of the burner and maintained in communication with a gas chamber formed in an outer marginal portion of the main body of the burner, and liquid fuel scattering means is rotatably mounted at an open end portion of the fuel gasifying member for scattering a liquid fuel in minuscule particles into the interior of the fuel gasifying member and the main body of the burner through a scattering gap. The liquid fuel thus scattered in the main body is ignited and burns to heat the fuel gasifying member in which the fuel supplied by the liquid fuel scattering means under the influence of an air blast supplied under pressure through an air supply duct is quickly gasified and forms a mixture of gasified fuel and air which is ejected through the gas chamber to sustain combustion of the liquid fuel in gasified form. A cooling chamber may be provided adjacent an inner wall plate of the main body of the burner.
