Definitions

  • the present invention relates to a method for feeding a plant fiber containing product divided into portions by means of a pressurized gas.
  • the invention further relates to a device for producing a predetermined portion- packed amount of a wet or moist plant fiber containing product according to the invention.
  • the brown colouring of the package is the result of the plant fiber containing prod- uct depositing, when moist, some discolouring plant extracts. It is desirable to moisten the plant fiber containing product, for example a portion-packed pinch of snus, to a moisture content of 40-50 %, since a drier product will cause the user's mucous membranes to dry up, which gives gum problems, and since a dry product hampers the absorption of nicotine.
  • the prior-art production of portion-packed tobacco products, such as snus and also other plant fiber containing products includes a number of currently used manufacturing methods and devices for manufacturing the portion packs.
  • the plant fiber containing product is, for technical reasons, first treated at a moisture content of about 20-30 %, packaged in portion packs and then sprayed with water to obtain the desired moisture con- tent.
  • the undesired discolouring of the packaging material occurs during this moistening treatment.
  • EP 0 138 649 B1 discloses a device for forming individual packets or pouches of snus.
  • the snus contained in a feed hopper is fed through a rotating feed wheel having a plurality of through holes to a fill tube and then to a device for filling the snus into a packaging material.
  • a feed nozzle pneumatically ejects the snus from the feed wheel. Moistening of the snus is carried out after packaging.
  • EP 0 149 985 B1 discloses a method for producing and packaging given portions of snus and an apparatus for carrying out the method.
  • Snus with a moisture content of 50-55 % is fed into pockets in a conveyor belt in which it is compressed and then subsequently blown out by means of pressurized air into a package.
  • the document further discloses a method for packaging the snus divided into portions.
  • EP 138 649 B1 and EP 0 149 985 B1 for packaging snus can be applied when packaging the plant fiber containing product according to the present document.
  • SE 506 146 discloses a method for packaging a fine particulate, mois- tened tobacco material with a moisture content of about 50 %.
  • the tobacco material is fed to a rotating positioning wheel provided with pockets for positioning the material.
  • the wheel is suspended in a vertical direction and, in its uppermost position, the material is supplied and compressed and, in its lowermost position, a piston pushes the compressed material out onto a con- veyor on which the packaging material is located.
  • An object of the present invention is to provide an alternative method and device, which wholly or in part eliminate the drawbacks of prior art described above.
  • a method for feeding a moist plant fiber containing product divided into portions comprising feeding a predetermined amount of the plant fiber containing product from a volume-defining unit to a portion pack by means of a pressurized gas.
  • a lubricant is added to the pressurized gas.
  • the lubricant may be either liquid or solid and may have such properties that make it suitable for food production and/or as a food additive.
  • Non-limiting examples of a liquid lubricant are water, glycerine, propylene glycol and polyethylene glycol.
  • Non-limiting examples of solid lubricants are powdered or particulate silicon-based lubricants, such as sand.
  • a lubricant which may be a liquid
  • a lubricating effect is obtained which facilitates the transport of the plant fiber containing product divided into portions from the volume-defining unit to the filling device. The risk of the device according to the invention being clogged due to the formation of lumps in the product may thereby be reduced.
  • This ability to feed moistened plant fiber containing material through the device for manufacturing products divided into portions in a safe manner enables the provision of a portion-packed plant fiber containing product packed in fresh pouches that are whiter than a pouch moistened at a later stage, since no subsequent moistening of the material in the pouches is required.
  • By feeding the product using a pressurized gas a safe and efficient way of transporting the predetermined amount is provided.
  • the lubricant may be added in pulses. By adding the liquid in pulses, an even more controlled way of adding liquid as a lubricant to the process according to the invention is obtained.
  • the pressurized gas may be air. This offers an inexpensive and simple system for feeding the predetermined amount of the plant fiber containing product through the device.
  • the pressurized gas may be an inert gas. According to one embodiment, said inert gas is nitrogen. By using an inert gas, or more specifically nitrogen, a hygienic agent adapted for feeding of the predetermined amount of the plant fiber containing product is obtained.
  • the lubricant may comprise water.
  • a water-based additive or only water a safe lubricant is obtained which is easy to use and handle.
  • the lubricant may be added when the portion amount is discharged from said volume-defining unit.
  • the plant fiber product comprises at least one of tobacco, beet fiber and cellulose.

  • the device comprises means for adding a lubricant to the pressurized gas.
  • the device may further comprise a duct for feeding the defined portion amount to a packaging unit, which is adapted to enclose the defined portion amount in a portion pouch made of a material permeable to liquid.
  • Fig. 1 is a schematic side view of a device for manufacturing a predetermined portion-packed amount of a moist plant fiber containing product according to one embodiment.
  • Fig. 2 shows a volume-defining unit according to one embodiment.
  • the invention will be described below with reference to a tobacco product, for example ordinary snus, but is not limited in any way to tobacco products only.
  • the invention is also applicable to various plant fiber contain- ing products, such as ground coffee and tea, or other products.
  • plant fiber containing products are tobacco, cellulose and beet fiber, and the plant fiber containing product may or may not contain nicotine and/or even an addition of nicotine.
  • the invention is thus applicable to snus, which usually contains ground tobacco, water, humectants, flavour enhancers, acidity regulators and aromas.
  • the material is usually produced in a process comprising pasteurization and holding. This process is well known to the person skilled in the art.
  • a device for forming individual portions of a moist plant fiber containing product divided into portions is shown.
  • the device may be used for only one portion-forming step, but may also be used for one or more additional steps in the processing of the product.
  • the portion-forming device comprises a container 1 for receiving the product to be divided into portions, either by batch filling, or through continuous feeding, for example via some kind of conveyor.
  • the container 1 may comprise a volume-defining unit 2, which according to the embodiment shown may be arranged in the bottom of the container 1.

  • a discharge unit 3 may be arranged below the volum-defining unit 2, and may be in the form of a substantially circular plate, which may be fixedly mounted relative to the volume-defining unit 2.
  • the discharge unit may, for example, be provided with a trough hole 9, which may be moved into alignment with a recess 8 of the volume-defining unit located in a predetermined position and with the pressurized gas nozzle 12, so that the discharge unit serves as a valve seat.
