This invention relates to a spray type retort sterilizer which performs various kinds of high-pressure sterilization of gas foods containing a lot of gas, transfusion soft pack for medicine, etc. and it object is to prevent the hot water drops spray on the object material for treatment (3) placed on the trays (2) disposed inside the tank (1) from instantly evaporating by boiling. The technical construction of this invention is that it is provided with a tank (1) in which trays loaded with the object material to be treated are stacked in a plural number of stages, spray units (4) which emit hot water or cooling water on the object material (3) on the tray (2) in each stage inside the tank (1) and a circulation route (5) through which to blow the water accumulated at the bottom of the tank (1) in the form of mist from the spray units (4) again under pressure through a pump (6) and a heat exchanger (7) and is also provided inside the tank (1) with an internal pressure adjusting system composed of a pressurized air intake system (11) which introduces pressurized air into the retort and an exhaust system (12) which evacuates gas from inside the tank (1). In a retort sterilizer having a construction as described above, the internal pressure of the tank (1) can be set at a pressure at which the desired hot water drops are not instantly atomized by boiling with mutual operations of the pressurized air intake system (11) and the exhaust system (12), thus providing a unique effect of making it easy to provide a retort sterilizer of high practical value which can blow desired hot water drops exactly and uniformly against the object material in the tank (1) and equalize the temperature in the entire area of spraying to ensure a treatment of high efficiency.
