  • Method and apparatus for cleaning containers with protective fogging
    Patent number: 4000002
    Abstract: A container washing system comprises a container washing zone, a rinsing zone and a deionized rinsing zone through which containers are conveyed. At each of the zones, spray nozzles direct washing and rinsing liquids at the containers. In order to prevent the etching of stationary containers when the conveyor is interrupted, the spray nozzles in the washing and deionized rinsing zones are deactivated. In order to prevent the oxidation or rusting of the stationary containers in the absence of the washing and deionized rinsing liquids, the containers are maintained in the moist condition by fogging nozzles located within the washing and deionized rinsing zones.
