Aseptic conveying system

An aseptic conveying system where a plurality of rotation wheels, each including a plurality of container holding sections on an outer periphery, are provided inside a chamber that is internally divided into a plurality of zones by a partition plate and where a container is conveyed by being transferred between the container holding sections of adjacent rotation wheels, wherein:

• the chamber is divided by the partition plate into an upstream zone that is maintained in an aseptic state, and a downstream zone that is provided adjacent to and on a downstream side of the upstream zone;
• a required rotation wheel among the plurality of rotation wheels is disposed as a transfer rotation wheel, and the transfer rotation wheel is provided across the upstream zone and the downstream zone separated by the partition plate;
• an opening is formed in the partition plate, the opening allowing a container holding section that moves due to rotation of the transfer rotation wheel to pass through;
• a tunnel that allows the container holding section of the transfer rotation wheel to pass through is further provided along a movement path of the container holding section, and a sterilizing nozzle for spraying a sterilizing agent toward the container holding section is provided inside the tunnel;
• and
• the tunnel is provided in the downstream zone, at a position adjacent to the opening where the container holding section passes through at a time of entering the upstream zone from the downstream zone;
• wherein after the container holding section of the transfer rotation wheel transfers a container to an adjacent rotation wheel of the plurality of rotation wheels on the downstream side, the container holding section not holding the container is sprayed with the sterilizing agent by the sterilizing nozzle while passing through the tunnel, and further, the container holding section sprayed with the sterilizing agent enters the upstream zone via the opening.
