Abstract
An object is subjected to high-pressure processing by bringing at least a high-pressure fluid into contact with the object under pressure in a high-pressure processing chamber, and then the high-pressure processing chamber is depressurized while the temperature in the chamber is controlled to be maintained above a temperature achieved by an adiabatic expansion, the adiabatic expansion starting from the pressure and temperature at the end of the high-pressure processing step. To control in such a way, the temperature in the high-pressure processing chamber is controlled so as to suppress or recover a temperature descent caused by an adiabatic expansion during the depressurizing step. This solves a problem in which the temperature is decreased to the vapor-liquid phase coexistence region or a region in which a solid is deposited.
