  • Patent number: 9173433
    Abstract: The invention relates to a tobacco shredding device with a heatable pressure chamber (3), which has a tobacco material inlet (5) at the low-pressure end, an expansion gap outlet at the pressure end and a shaft-mounted conveyor screw (1) for conveying the tobacco material from the inlet to the outlet, and the conveyor screw shaft (19) is supported at the inlet end, and the shaft (19) extends on behind the outlet, where it is supported again by a counter bearing (17). It further relates to a method of shredding tobacco, whereby the tobacco material is introduced at the low-pressure end of a pressure chamber and is expanded and discharged at the pressure end of the chamber at a gap outlet, and the tobacco material is conveyed from the inlet to the outlet by means of a conveyor screw shaft-mounted at both end portions, and the conveyor screw is operated in a speed range of up to 600 min?1.

  • Patent number: 7159594
    Abstract: The invention relates to a method for adjusting the selecting out of winnowings in the manufacture of smokable products, in particular cigarettes, wherein the current size distribution of a stream of tobacco particles passing a measuring point, per unit of time, is detected and compared with a settable nominal size distribution, and wherein an arrangement for separating the winnowings is continually adjusted, depending on the result of said comparison, and to a corresponding device comprising a sensor for detecting the current size distribution, an arrangement for inputting a nominal size distribution, an arrangement for comparing said current size distribution with said settable nominal size distribution, and lastly an adjusting arrangement for setting the arrangement for separating the winnowings, depending on the output signal of said comparing arrangement.

  • Patent number: 6263881
    Abstract: The invention relates to an apparatus for applying a liquid medium, more particularly, a flavor or menthol, to tobacco in a cigarette maker equipped with a conduit for feeding the liquid medium, and provided at the end of the conduit with a nozzle orifice, disposed under the suction band of a cigarette former of the maker and, through its nozzle orifice, applies the liquid medium to the tobacco in contact with the tobacco carpet. The nozzle orifice sweeps past the surface of the tobacco and applies a fine continuous jet of the non-foamed liquid medium, or an aerosol jet of the liquid medium, onto the tobacco.
