Definitions

  • the invention relates to a system for conveying comminuted tobacco material having a moisture content of 35% or more, a tobacco dispenser and a method for conveying comminuted tobacco material having a moisture content of 35% or more.
  • shredded tobacco material with a moisture content of 35% or more is meant in the context of the present application, in particular a ground or cut tobacco with a high moisture content.
  • SNUS tobacco As a tobacco material thus ground or cut tobacco and possibly additives come into question.
  • the cut length is so short that the cut moist tobacco material has a similar consistency as ground moist tobacco material.
  • Such a moist ground or cut tobacco material Among other things, it is offered as so-called SNUS tobacco or smokeless tobacco and is used orally, ie in the oral cavity.
  • SNUS tobacco has a moisture content of about 35% to 50% or more and is a fine-grained, lumpy substance that is similar in consistency to wet coffee grounds.
  • SNUS tobacco is in some cases flavored with, for example, menthol, sal ammoniac or other flavoring agents, and is packaged in portions of 0.5 to 2 grams in so-called SNUS bags.
  • This is a porous paper, the so-called “pouch”, which is completely sealed, but permeable to water and releases the ingredients of the "pouch” in the mouth and the mucous membranes of the mouth.
  • the most common portion size is about one gram per serving. After consuming the "pouch" this is taken out of the mouth and disposed of.
  • the moist, shredded tobacco material of SNUS tobacco clumps which requires special processing methods.
  • the machines used to manufacture the SNUS pouches have hitherto been fed by hand with the shredded, moist tobacco material which has previously been kept refrigerated in containers in large refrigerated spaces.
  • the containers in which the moist, shredded tobacco material is stored are covered so that the moisture of the tobacco material does not escape.
  • care must be taken to ensure that the material does not dry out and heats up as little as possible.
  • the present invention has the object to provide a system, system components and a method for conveying moist, shredded tobacco material available, with which the consistency of the wet tobacco material is maintained and an automatic promotion is possible without heavy burden on people.
  • a system for conveying comminuted tobacco material with a moisture content of 35% or More comprising at least one tobacco end device and at least one tobacco receiving device, which are interconnected by means of at least one pressure-tight tobacco conveying tube, a control device and a controllable by the control device closure element, by means of which a connection of the tobacco end device to the tobacco conveyor tube is closable, and an air suction device, by means of which a negative pressure in the tobacco conveying pipe is producible, wherein the control device is designed to close the closure element to build up negative pressure in the tobacco conveying pipe and to open after the build-up of negative pressure for conveying tobacco material through the tobacco conveying pipe.
  • the invention is based on the basic idea that a conveyor system for shredded tobacco material with a high moisture content provides a cyclically intermittent delivery of the moist, shredded tobacco material.
  • one or more Tabaksendevoriquesen and one or more tobacco receiving devices are provided, which are interconnected by means of one or more pressure-tight tobacco delivery tubes.
  • a negative pressure is built up in the tobacco-conveying tubes, for example between 100 hPa and 300 hPa, with no air flow occurring in the tobacco-conveying tube except for the air suction.
  • the connection to the tobacco sending device is opened, so that wet, shredded tobacco material is sucked into the vacuum-loaded tobacco conveying tube and transported therethrough.
  • the pressure equalization adjusts an air flow, which is directed by the tobacco end device in the direction of the tobacco receiving device. Because it is not a circulating airflow, as in others pneumatic conveying systems, this air flow is not heated, but corresponds to the ambient air, so that drying out of the moist tobacco material is effectively prevented.
  • the tobacco material can travel a distance of several meters within the tobacco conveying tube, with very little material adhering and remaining to the tobacco conveying tube wall. The loss of tobacco material is thus minimal. This is also related to the intermittent mode of operation which minimizes agglomeration of material on the pipe wall by pressure surges and air ripples.
  • the control device and the Laufabsaugvoraires cyclically alternately with a sealed connection between the tobacco dispenser and tobacco conveyor tube, the negative pressure in the tobacco conveyor tube generated and after reaching a preset or presettable negative pressure in the tobacco conveyor tube when opening the connection to the tobacco end delivery device, a pressure compensation with an air flow thrust to the tobacco receiving device can be generated.
  • the preferred intermittent operation of the system is ensured by the control device and the Heilabsaugvorraum.
