Embodiment Construction

[0027] figure 1 The steps of the sterilization method for PET bottles to be filled are shown. The PET bottles are conveyed, for example, by means of a continuous conveyor into the injection machine, for example as it is described in EP1144016B11. The injection machine has a rotary part with accommodation for PET bottles. A mixing nozzle for blowing a mixture of water vapor and disinfectant into the interior of the PET bottle for internal sterilization 2 is installed on the turntable of the turntable. The mixing nozzle can be a two-component spray nozzle. Cooling of the outer wall of the PET bottle is performed simultaneously with internal sterilization 2. In order to achieve a high degree of sterilization, a mixture of water vapor and disinfectant is blown into the interior of the PET bottle at very high temperatures, in particular above 95° C., where it deposits on the inner wall. In order to eliminate shrinkage of the PET bottles during the internal sterilization 2, cool...

Abstract

The invention relates to a method of sterilization of packaging containers. Disinfection of bottles by simultaneously applying steam containing disinfectant liquid in the interior of the bottles at temperatures over 90 DEG C (especially at temperatures over 95 DEG C) and disinfection solutions on the exterior of the bottles at temperatures under 40 DEG C (especially at temperatures 20-30 DEG C).

Description

technical field [0001] The present invention relates to a method for sterilizing packaging containers and in particular PET bottles prior to filling. Background technique [0002] When filling liquid food products such as fruit juices into packaging containers, especially plastic containers such as bottles made of polyethylene terephthalate (PET), a high degree of cleanliness must be observed. It is especially necessary that the outside and especially the inside of the packaging container be sterilized before filling. Sterilization is usually carried out with the aid of a mixture of water vapor and a disinfectant. For example, a vapor mixture of water vapor and peracetic acid is introduced into the interior of the packaging container by means of a binary nozzle, where it is deposited on the inner wall. The outside of the packaging container can be sterilized by means of heated peracetic acid. [0003] The higher the temperature, the more effective the sterilization proces...
