Abstract

The invention discloses a device for sterilizing PET bottle blanks by coupling ray irradiation with gaseous hydrogen peroxide. The device comprises a bottle blank conveying track, a ray irradiation sterilization section, a gaseous hydrogen peroxide sterilization section and a heating section, wherein the bottle blanks sequentially enter the ray irradiation sterilization section, the gaseous hydrogen peroxide sterilization section and the heating section through the bottle blank conveying track to complete comprehensive sterilization, and a ray irradiation pre-sterilization section is used for sterilizing the outsides of the bottle blanks; the gaseous hydrogen peroxide sterilization section is used for sterilizing the necks and the interiors of the bottle blanks; and the heating section is used for accelerating removal of ozone generated by ray irradiation, and activating gaseous hydrogen peroxide attached to the bottle blanks so as to further improve the sterilization effect and accelerate volatilization of the gaseous hydrogen peroxide. According to the device for sterilizing the PET bottle blanks, ray irradiation and the gaseous hydrogen peroxide are coupled to achieve the synergistic effect on the outer surfaces, the interiors and the necks of the bottle blanks, the sterilization efficiency is high, the sterile state of the bottle blanks is guaranteed, physical sterilization energy consumption is reduced, and meanwhile, the use amount of the gaseous hydrogen peroxide is reduced, and the hydrogen peroxide residual risk is reduced.

Description

technical field [0001] The invention relates to the technical field of aseptic filling of liquid beverages, in particular to a sterilizing device for ray irradiation coupled with gaseous hydrogen peroxide used for PET bottle blanks. Background technique [0002] PET bottle refers to a plastic packaging bottle made of polyethylene terephthalate (Polyethylene terepthalat, PET) polyester through injection molding and blowing. It is widely used in the field of beverage packaging and has become a The fastest growing packaging material. PET aseptic filling technology has been developed and matured in recent decades. It is a modern beverage filling production integrating opto-mechanical integration technology, modern chemistry, physics, microbiology, automatic control, computer communication and other high-tech. In recent years, through continuous innovation and development and continuous improvement of the industrial chain, it has gradually developed into a major production metho...
