<P>PROBLEM TO BE SOLVED: To provide a steam-mixing-type heat sterilizer can stably conducting a high-quality sterilizing treatment in accordance with a practical sterilizing treatment situation. Ž<P>SOLUTION: The steam-mixing-type heat sterilizer includes a heating system functioning to mix steam into a to-be-heat-sterilized fluid to heat the fluid, and a sterilizing treatment system functioning to conduct a sterilizing treatment on the thus heated fluid; wherein the heating system includes at least a steam-mixing pump 4 as a powered mixer functioning to convey a fluid under pressure rise by the action of a rotor and mix steam into the fluid under conveyance, and. In addition, the heating system includes a pressure sensor 19 functioning to detect the pressure of a fluid on the entrance side of the pump 4 and a pressure control section PIC-1 functioning to control the revolution level of the rotor in response to the pressure value detected by the sensor 19 and, based on the result, control the pressure of the fluid on the pump entrance side.
