Vacuum sterilizer

The sterilizer ADV of Bosch Packaging Technology is suited for vacuum sterilization of porous loads, as well as for sterilization of liquids according to the steam/air mixture process. The combination of both processes on one machine offers high flexibility.

The steam/air mixture process is used for the sterilization of liquids in open, semi-closed and closed containers. It is characterized by dry removal of the containers from the sterilizer. During the sterilization process, the steam/air mixture is circulated inside the chamber by ventilators, and a homogenous temperature distribution is achieved. Internal heat exchangers circulate sterile air for cooling. During the entire process, counter-pressure is maintained in the chamber to prevent damages to the product. At the end of the cycle, dry removal of the load is possible.

The vacuum process is especially suited for sterilizing machine parts, filters, rubber stoppers and equipment. Rigid and porous loads, as well as machine cavities can be sterilized using the steam/vacuum process. Pre-vacuum steps ensure the elimination of air from the chamber. Heating and sterilizing is achieved by saturated steam. Depending on the load, this step is followed either by a drying vacuum or jacket cooling.

The sterilizer, type ADV, unites equipment sterilization via vacuum process with product sterilization via steam/air mixture process. The combination of these two processes offers highest flexibility: the sterilizer can be used for almost any product and is also suited for the development of new products. Flexible recipe editors enable quick and individual adjusting of parameters. The ADV has been developed for research institutes and laboratories, as well as for the pharmaceutical and biotechnical industries. It sterilizes goods packed in blisters, machine parts, contact lenses, blood bag systems and nested glass syringes, ampoules and vials, and glass or plastic bottles.
