Abstract: An apparatus for packaging a product in containers includes a sterilization station and a conveyor for intermittently conveying containers to the sterilization station. A vaporizing nozzle communicates with a reservoir of liquid disinfectant containing hydrogen peroxide and a source of compressed air. The nozzle is intermittently opened and closed whereby the compressed air vaporizes the disinfectant and a mixture of liquid disinfectant in fine droplets and compressed air is ejected when the nozzle is open. A tube is connected with its intake end at the nozzle and is disposed parallel to the jet emitted from the nozzle. A heater on the tube heats the inner surface of the tube to a temperature that is sufficient high to rapidly evaporate the disinfectant in the mixture. As a result a mixed flow of compressed air and evaporated disinfectant leaves the output end of the tube and enters the container in the sterilization station.

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.

Abstract: According to the method of the invention the packing means, for example yoghurt containers, are introduced into a sterilizing chamber, which is sealed. The interior of the chamber is then evacuated and then pressurized steam is intoduced into it. This leads to a temperature rise and consequently to a sterilization of the packing means. The steam is only introduced for a brief period, e.g. for 5 seconds. The sterilizing chamber is then evacuated again and steam and condensate are removed. Cold sterile air is then blown into the chamber, which leads to a fast cooling of the packing means.

Abstract: A method for the sterilization of a machine used in the formation, filling and sealing of plastic containers. A source of sterilizing agent, such as steam, is used to sterilize the various passageways, filters, and components within the machine which, if contaminated, would contaminate the liquid in the filled plastic container. Pressurized air or gas is delivered through sterilized lines having a micro-organism filter. The air flowing out of each filter is sterile and free from bacteria. A series of unique, easy to sterilize, three-position, two-way valves are used to duct pressurized gas and steam to the various components. A special air drop test apparatus is used to operationally check the integrity of the filters without breaching the sterile condition of the various fluid passageways and interconnected components.
