Abstract
PURPOSE:To carry out sterilization of a packaged material in a retort of a pressure vessel preventing the deformation of the vessel, by controlling the pressure in the retort under specific condition and raising the temperature in the retort at the highest permissible rate of temperature increase to enable the heating of the packaged material. CONSTITUTION:A packaged material 2 prepared by sealing a content in a vessel having definite shape such as a semi-rigid vessel is placed on a shelf in a retort which is a pressure vessel provided with an openable lid. The temperature in the retort is uniformized with water or hot water, etc., collected at the bottom of the retort. The pressure in the retort, i.e. the temperature of saturated steam is controlled by controlling the feeding rate of steam while detecting the deformation of the packaged material 2 or its equivalent and the highest rate of temperature increase is controlled by the heat-transmission characteristics of the packaged material 2 and the heat capacity of the content. The content can be sterilized without causing the deformation of the vessel and the shape collapse of the content.
