- Each cigarette manufacturing unit preferably has one only machine-side dedusting device for the common exhaust air flow from the strand machine and the filter attachment machine on.
- the electrical supplied to a cigarette manufacturing combination Performance is essentially at the machine Friction implemented and given off as heat.
- the vast majority Part of this heat must be extracted with the machine (approx. 45 ... 50 ° C) are removed from the cigarette manufacturing unit.
- the exhaust air dedusted from the machine can after Fan are cooled down as far as possible via a heat exchanger, that together with a usual fresh air content for Room air conditioning can be used.
- a heat exchanger can e.g. Water or other liquid medium are heated so that the waste heat of the extrusion machine and the filter attachment machine no longer via exhaust air ducts from large cross section must be dissipated, but through that liquid medium can be derived, for which lines from much smaller cross-section are sufficient.
- the one for the Air circuits required for cigarette manufacture Cigarette rod formation and filter attachment can be a further air cycle to be superimposed with the aim of additional heat generated on the machine at a high level Extract, remove dust, cool down temperature level then add it back to the workspace. So that exists Possibility of converting the entire electrical into frictional heat Energy via the liquid-cooled heat exchanger dissipate and in the sense of air conditioning the cigarette manufacturing unit to make it energetically neutral.
- the individual dedusting device is preferably in the Formed so that two groups of one or more Filter cartridges are provided, the groups alternating work so that the exhaust air flow of the strand machine and the filter attachment machine by the one group of Filter cartridges are routed while the second group of Filter cartridges is cleaned.
- the cleaning takes place on mechanical way by brushing and mechanical vibrations.
- the mechanical cleaning has short pressure impulses the advantage that there are no pressure pulses to the strand machine or can propagate to the filter attachment machine.
- Both groups of filter cartridges are constantly under pressure so that even if there are any leaks in the control flaps there is no risk of tobacco dust escaping.
- Another dedusting filter can be installed in the individual dedusting device provided with a downstream fan be the air from inside the strand machine and the filter attachment machine.
- the cleaned exhaust air can also be cooled in the heat exchanger and then again be fed into the room. This can reduce the heat load of the space can be further reduced.
- FIG. 1 shows a single cigarette manufacturing unit 10 in schematic form.
- a cigarette manufacturing facility exists from a variety, e.g. 30, such cigarette manufacturing units 10, whose exhaust air flows via a central Dedusting device 11, which is also schematic in FIG. 1 is shown to be cleaned.
- the cigarette manufacturing unit consists of a tobacco feeder 12, via a feed line 13 Cut tobacco is fed pneumatically.
- the pneumatic one Promotion of exhaust air containing tobacco dust leaves the tobacco feeder 12 via an exhaust pipe 14.
- the tobacco feeder In the tobacco feeder the supplied cut tobacco in a storage container (not shown) collected. If the storage container is full, then the pneumatic cut tobacco supply is interrupted, in the exhaust air line 14, a control valve 24 is closed.
