ABSTRACT:
An object such as a food packaging material is sterilized first by immersion in a nontoxic sterilizing liquid and then by exposure to ultraviolet irradiation. The sterilizing liquid can be either an organic acid solution or hot water. Alternatively, the object is simultaneously treated with both sterilizing agents, by being irradiated with ultraviolet rays while being dipped in the sterilizing liquid. The liquid is reconditioned, as by filtration and ultraviolet irradiation while being recirculated through a closed circuit. The apparatus is disclosed as adapted for the sterilization of a continuous strip of food packaging film.
