Abstract: A sterilizing apparatus for sterilizing a hollow prism-shaped carton open at both ends includes a sterilizing station, a drying station, and a solution-removing station located between the sterilizing station and the drying station. The solution-removing station has a solution-removing device which rotates intermittently in synchronism with carton conveyers. The solution-removing device includes a plurality of thin and long mandrels extending in a radial direction and spaced apart from each other at regular intervals. Each mandrel supports a carton and has a nozzle which supplies the aseptic air from an aseptic air source into the carton.

Abstract: The present invention provides a microwave heating sterilizer provided with a mechanism for turning over a retainer made from a material being permeable to microwave and which contains a "material to be sterilized" in a cavity irradiated with microwave therein supporting shafts extend from positions determined at point symmetry with respect to the center of the retainer on the opposite ends thereof, and turning-over parts each having a higher slide surface than the other part thereof on the midway of a guide which conveys the retainer and a turning-over groove on the midpoint thereof are provided.
