Abstract: Provided are a method and device for generating a steam heating medium, the method involving generating, from a nozzle, Aqua-gas or low-temperature superheated steam that is a steam heating medium by operating an electrothermal-type generator or a steam-type generator. The method comprises the step of generating Aqua-gas by increasing a water supply amount in such a manner that an internal nozzle pressure takes on a constant value exceeding a saturated water vapor pressure of water at each internal nozzle pressure set temperature; or generating low-temperature superheated steam by reducing the water supply amount in such a manner that the internal nozzle pressure does not exceed the saturated water vapor pressure of water at each internal nozzle pressure set temperature, in a relational expression relating to a flow rate of water vapor sprayed from the nozzle, and given by Expression 1 or Expression 2, as prescribed in the present invention.

Abstract: A method for heating and pasteurizing a material, comprising placing the material inside of a semi-sealed chamber at atmospheric pressure that contains an atmosphere produced by replacing air in the chamber with a gas component produced by spraying or injecting hot water droplets and steam at a temperature of at least 100° C. into the chamber which is heated to a temperature of at least 100° C. which is equal to or higher than the temperature of the sprayed hot water droplets and steam, which gas component has a humidity of at least 95% and contains no more than 1% oxygen; contacting said material to the gas component for exposing it to continual temperature variation during heating ranging from 10-50° C. inside the chamber at temperature(s) ranging from 90-180° C. for a time sufficient to heat or pasteurize it. An apparatus for performing this method.

Abstract: The present invention provides a method of heating and pasteurizing in use of gaseous water and an apparatus therefor, and the present invention relates to a method of heating and pasteurizing a material to be treated, comprising the steps of: continuously injecting hot water heated to at least 100° C. and/or steam into a heating chamber comprising a semi-sealed space and heated to at least the same temperature as the hot water and/or steam, to form water microdroplets and moist hot steam; replacing the air within the heating chamber with the water microdroplets and moist hot steam to effect filling with a gas component that has a composition of at least 95% humidity and an oxygen concentration not greater than 1% and that is maintained in the temperature range of 90 to 180° C.; and carrying out a heating and pasteurizing treatment by effecting, with the water microdroplets and the moist hot steam, continuous amplitude heating at a temperature difference of at least 10° C.
