Method for cleaning containers and cleaning machine
First Claim
1. A method for cleaning containers, in a cleaning machine, in which in several stations and process steps, at least one cleaning medium is allowed to act on the containers conveyed by the cleaning machine, comprising cleaning the containers in at least one station with at least one cleaning medium;
- and wherein in at least one pre-cleaning step, wetting each container with chemical-free water essentially on all sides, pre-soaking dirt accumulations present on each container for a predetermined period, pre-cleaning an exterior of each container by blasting with chemical-free compressed pure water, subsequently internally cleaning each container over at least one further predetermined period at least by pressure blasting an inner surface of the container with granular material and a carrier medium, subsequently rinsing each container with chemical-free water, and finally disinfecting each container by applying ozone to the container.

Abstract
A method for cleaning containers, in particular bottles of glass or plastics, and a cleaning machine with at least one cleaning medium, with the containers cleaned at least in one station preferential for the cleaning result and/or in a procedure step with at least essentially chemical-free cleaning media. The cleaning medium is advantageously a granular material, in particular granular ice, carried under pressure with compressed air or compressed water. The cleaning machine suited for carrying out the method includes downstream of an unpacking and presoaking station, a pre-cleaning station with a high pressure water blasting pre-cleaning section, and subsequently an intensive cleaning station with at least one intensive cleaning section to which a pressure blasting system for chemical-free, granular material and a carrier medium are associated, and a disinfection station following the intensive cleaning station.
