  • Patent number: 5322074
    Abstract: An exhaust fan draws air and entrained tobacco through delivery pipes from a tobacco feeder to the respective dischargers of a group of cigarette making machines, where the tobacco is screened out and the air passes on through exhaust pipes. When a discharger is to release tobacco to its making machine the feeder stops delivery of tobacco to that discharger and, after a delay to clear the delivery pipe, a valve bypasses the air around the discharger so that a constant air flow is maintained. The feeder supplies tobacco in a separate and independently controlled stream to each discharger, and has oscillating vanes to separate and keep the tobacco moving.

  • Patent number: 5259403
    Abstract: Tobacco cut filler is volume expanded using the DIET process and equipment. During depressurization of a pressure vessel containing a mixture of cut filler impregnated with liquid carbon dioxide, gaseous carbon dioxide is bubbled through the mixture to provide a mixture of decreased density and decreased integrity. Liquid water is introduced into the sublimator region of the equipment in order to act as a heat sink, causing tobacco cut filler in that region and related equipment components to not experience overly high exposure to heat. A vertically extending duct in the sublimator region has a relatively large inner diameter so as to allow adequate residence time of the tobacco cut filler in the expansion region. A spray of water applied to the expanded tobacco cut filler and atmosphere in the post expansion region of the DIET equipment moistens the cut filler and reduces the temperature experienced thereby.

  • Patent number: 5186183
    Abstract: In an apparatus for detecting micro-holes of a cigarette having a filtered section, cigarettes are successively carried to a support section which is rotated and each of the cigarettes is supported between pads 14a and 14b. The supported cigarette is moved to a pre-pressuring stage in which one end face of the cigarette is closed and a pre-pressure is applied to other end face of the cigarette from a pre-pressure source. Therefore, the cigarette is reached to a measuring stage in which a measuring pressure is applied to the other end face of the cigarette so that air flows through micro-holes of the filter section and a reduced pressure is appeared in the one end of the cigarette. The measuring and reduces pressures are detected by pressure transducers and electrical signals from the transducers are proceed so that dilution value of the cigarette is calculated.
