Abstract
A disposable fermenter that may be used in the place of a more expensive jar fermenter giving the same performance in a temperature controlled room in place of a sterilized room, with the advantage of not being made of glass which breaks and which may be transported as is, by just sealing the bag. A flat tube made of plastic film is inserted into the bottom of the bag with the tube sealed to the bag, leaving an opening through the tube so the opening may not be closed. Once the addition of liquid, semi fluid or solid media is made, the breather is set and the bag opening is sealed, the bag is sterilized before or after the bag opening is sealed and the aeration is done through the flat tube.
Claims17
A disposable fermenter comprising a fermenting bag for containing a medium, the fermenting bag having a flat tube affixed at a bottom or lower portion of the bag and at least one means for breathing inserted and fixed to the bag at a position where the means for breathing is always above a maximum level of the medium contained in the bag, the bag being made of a plastic film, the flat tube being made of a plastic film and extending inwardly into the bag and outwardly from the bag, the flat configuration and position of the tube preventing the egress of the medium from the bag and the ingress of contamination into the bag by pressure exerted on the tube by the medium while permitting aeration.
A disposable fermenter comprising a fermenting bag for containing a medium, the fermenting bag having a flat tube affixed at a bottom or lower portion of the bag and a staggered seal to an upper portion of the bag resulting in an opening which permits the egress of gas and prevents the ingress of contamination, the bag being made of a plastic film, the flat tube being made of plastic film and extending inwardly into the bag and outwardly from the bag, the flat configuration and position of the tube preventing the egress of the medium from the bag and the ingress of contamination into the bag, by pressure exerted on the tube by the medium, while permitting aeration.
