ABSTRACT:
An apparatus for aseptically filling and sealing preformed bags includes a carousel table supporting a number of bags along its periphery, each bag having a nozzle initially sealed by a diaphragm. As the carousel table brings an individual bag under a sterile docking unit, that unit lowers over the bag and showers the nozzle and diaphragm with HEPA filtered air to remove particulate matter and bioburden. A flash heat sterilizer sterilizes the diaphragm and the top of the nozzle and at least partially melts the diaphragm. A heat sterilized fill pipe descends, piercing the diaphragm and filling the bag. When filling is completed, the fill pipe partially withdraws, the lower portion of the pipe remaining inserted in the nozzle. A heat sealer then seals the nozzle below the tip of the pipe. The pipe completely withdraws, the sterile docking unit moves clear of the bag, and the carousel table rotates, thus moving an empty bag into position for filling.
