Abstract
A sterilization method for a sterile liquid-content packing machine using liquid disinfectant for sterilizing parts of a filler pipe and connecting piping in free communication with the filler pipe requiring sterilization. A preheating heat-storage piping is provided having a capacity for holding a predetermined quantity of heat transferred to the heat piping by passing super heated air therethrough. Spray charging of a predetermined quantity of liquid disinfectant occurs for a predetermined period of time into the super heated air passing through the heat storage piping which results in vaporizing the liquid disinfectant while dropping the temperature of the mixture of vaporized disinfectant steam and super heated air due to the vaporization. The drop in the temperature of the mixture is inhibited by heat stored within the heat storage piping. The mixture is communicated within the connecting piping to be sterilized which extends from the heat storage piping. The connecting piping is at a lower temperature than the dew point temperature of the mixture without cooling the connecting piping, whereby the mixture is condensed evenly as a film of liquid disinfectant on the surfaces of inner walls thereof. A second heated air having a lower temperature relative to the super heated air is communicated into contact with the condensed liquid disinfectant for vaporizing the condensed liquid disinfectant and removing the condensed liquid disinfectant from the surfaces of the connecting piping.
