ABSTRACT:
While a sealed vessel such as a vial having an inside plug such as a rubber stopper is conveyed, the sealed vessel is slanted by a slanting device until liquid medicine in the sealed vessel touches the inside plug. The sealed vessel is moved and simultaneously rotated by a rotating device while the vial is slanted. The liquid medicine in the sealed vessel is heated at a heating portion by heat energy such as infrared, fuel gas and microwave, so that the heated liquid medicine causes heat sterilization of the whole sealed vessel including the inside plug. Sterilization can be completely carried out by providing a heat-retaining portion, cooling portion and drying portion next to the heating portion. An infrared radiation thermometer is provided at the end of the heating portion to measure the temperature of the liquid medicine, so that the temperature of the liquid medicine in each sealed vessel may be controlled to a desired temperature.
