BLASH MACHINE WITH CIP CLEANING SYSTEM FOR MANUFACTURING PLASTIC BOTTLES, AND CORRESPONDING METHOD

摘要

The machine (1) has valve blocks (5) with valves (6, 7) and blowing nozzles (17) for introduction and discharge of blow air (9). The blocks and the nozzles are assigned to blowing stations (2). The valve blocks and a cleaning-in-place (CIP) cleaning system clean the machine. The valve blocks are pneumatically operated, and the valves comprise CIP blocking valves for blocking pneumatic control lines of the valves. The valves comprise seals that are resistant to CIP cleaning agents such as hydrogen peroxide, peracetic acid, alcohol and soap. An independent claim is also included for a method for cleaning-in-place cleaning of a blowing machine.
