Definitions

  • the invention relates to a method for applying a gaseous and / or water-containing conditioning medium on moistened tobacco material inside an essentially free flow path of the tobacco.
  • the invention also relates to a device for applying a gaseous one and / or water-containing conditioning medium to moistened Tobacco material within an inlet opening and an outlet opening essentially free flow chamber.
  • the tobacco material treated in the manner described at the outset is to be understood in particular as cut rib and / or leaf material.
  • Such tobacco material can be treated for different purposes with regard to the intended condition of the end product produced therefrom, such as cigarettes, or the condition of the intermediate stages of the tobacco material that have been produced.
  • a preferred type of treatment in the sense of the invention aims to improve the so-called filling capacity of tobacco material by increasing its specific volume under the action of water vapor on the moistened tobacco and a subsequent drying process.
  • the invention has for its object the treatment mentioned above the tobacco in order to achieve an improved work result or To optimize the final product.
  • This object is achieved in that the tobacco is moved radially through a rotating radiation curtain of the conditioning medium.
  • a preferred effect is achieved according to a further proposal in that the tobacco expands under the action of steam through the radiation curtain as it passes through the flow path.
  • An additional effect which consists in the fact that existing tobacco is dissolved and separated in the form of more or less clumped fibers, is achieved according to an advantageous further development in that the tobacco is mechanically accelerated in the flow path during exposure to the conditioning medium.
  • the tobacco intended for expansion can be moistened in any preceding process step.
  • a preferred, particularly effective or compressed process sequence consists in moistening the tobacco as it enters the flow path.
  • the tobacco is dried after being passed through the radiation curtain or is fed to a drying section.
  • the tobacco is moved through a beam curtain composed of several individual beams distributed over a circular circumference.
  • the efficiency can be improved further by moving the tobacco through at least two successive beam curtains. The tobacco is expediently moved through the flow path essentially in the direction of the fall.
  • the device for carrying out the method described at the outset consists in that at least one nozzle orifice for the conditioning medium which rotates about an axis which runs essentially transversely to the flow direction of the tobacco and essentially radially emerges, is arranged within the flow chamber.
  • the flow chamber is designed as a tobacco expansion chamber.
  • the conveying means is designed as a hollow shaft provided on the circumference between the nozzle openings with driving pins.
  • the dwell time of the tobacco fibers in the zone of action of the radiation curtain can be influenced by detecting and dissolving clumps of fibers and thereby exposing the individual fibers to steam radiation for a sufficiently long and intense period, or to a large extent accelerating them in the direction of their fall. It is fundamentally possible to moisten the tobacco intended for expansion at any point and in any way.
  • a particularly advantageous and effective embodiment consists in that water nozzles emerging from chamber walls of the flow chamber are provided in the region of the chamber inlet opening. In this way, humidification and damping and thus expansion of the tobacco fibers is possible in a confined space.
  • a compact, easily integrable device for expanding tobacco fibers is provided according to a further development in that a cell wheel lock is arranged upstream of the flow chamber and a current dryer is arranged downstream on the output side.
  • At least two conveying means which are provided in the flow direction of the tobacco and are provided with nozzle openings and driving pins are provided within the flow chamber.
  • a versatile unit in particular for conditioning and transferring tobacco, or alternatively suitable for the cleaning of upstream and downstream devices by exposure to water, consists of a means enclosed by inlet and outlet side open chamber walls for transporting or transferring tobacco between feeding and laxative Tobacco transport or treatment devices, the conveying means being designed as a radially transporting winnover roller which has a hollow shaft provided with radial nozzle openings, which can be optionally connected to a steam and / or water supply.
  • the advantage achieved by the invention consists in a procedure that is gentle on the tobacco and can be designed with relatively little technical effort for a relatively large tobacco throughput and intensive action on the largest possible number of tobacco particles. In this way, an excellent expansion result of the tobacco fibers is achieved in particular.
  • a flexible or versatile unit offering an option is obtained with which either a humidification and expansion or. Drying effect on the tobacco or a cleaning effect on the directly allocated funding is possible.
  • the device for expanding sliced tobacco 1 in the form of a rib cut or leaf cut has a flow chamber 2 serving as an expansion chamber, in which a rotatingly driven conveying means in the form of a Winnover roller 3 is arranged:
  • the Winnover roller 3 consists of a hollow shaft 4, which according to Figure 2 is provided with nozzle openings 6 (for example Laval nozzles of the model 630 from Schlick KG, Coburg, FRG) distributed or staggered over their circumference and width, and driver pins 7.
  • the hollow shaft 4 is provided with the lines indicated by arrows 8 and 9 for a conditioning or cleaning medium in the form of steam or water, with which the nozzle openings 6 can alternatively be acted upon, the outlet jets 11 of which overlap over the width of the Winnover roller 3 according to FIG and thereby form a rotating beam curtain 12.
  • the flow chamber 2 has an upper inlet opening 10, in the area of which from the chamber walls opening into the flow chamber, via a feed line (arrow 13) fed water nozzles 14 for moistening the tobacco 1 fed via a rotary valve 16 with a rotating rotary valve 17, which are provided alternatively, could be moistened by a separate moistening device before entering the rotary valve 16.
  • the flow chamber 2 is also connected via a lower outlet opening 18 to a tubular flow dryer 19 which is made of hot gas with or without steam, in particular hot air or hot steam (superheated steam) with a temperature between 150 ° C and 600 ° C, in particular between 200 ° C and 400 ° C, e.g. B. 300 ° C, in the direction of arrows 21.
  • a cylindrical part 19a of the current dryer 19 changes into a trough-shaped form 19c via a transition zone 19b and from there into a further tubular part 19e via a further transition zone 19d.
  • a half orifice 22 is provided, which leads to a pressure drop at the outlet opening and constricts the flow of the drying medium in such a way that deposits on the wall of the flow dryer 19 opposite the Winnover roller 3 are avoided.
  • the supply of the tobacco parts through the Winnover roller 3 is facilitated in the region of the outlet opening 18.
  • the mode of operation of those used in particular in the area of the flow chamber 2 Means to increase the specific volume of the tobacco material as follows:
  • the portioned from the cellular wheel 17 into the flow chamber 2 Tobacco 1 is at a water content when passing the activated water nozzles 14 on the order of about 32% to 50%, preferably between 40% and 45% moist.
  • the moistened tobacco 1 passes in free fall through the winnover roller 3 rotating at approx. 200 rpm, the pins 7 of which, if necessary, dissolve or separate coherent tobacco fibers.
  • the saturated steam which emerges in a preferred amount of about 0.3 to 0.6 kg per kilogram of tobacco at a pressure of about 1 to 10 bar from the nozzle openings 6 of the hollow shaft 4 and forms a rotating jet curtain 12 with its overlapping exit jets 11 on the falling tobacco 1 and expands it by increasing the vapor pressure inside the fibers as a result of condensation heat released on their surface and penetrating into the fibers.
  • the expanded tobacco in particular in the form of a rib cut, then passes into the stream dryer 19 through which superheated steam flows, in which it releases moisture to the drying steam.
  • Winnover roller 3 is operated as a rotating cleaning device by Rotating water introduced into the hollow shaft 4 from the opposite side (arrow 9) Exit jets 11 exits the nozzle openings 6 and the Winnover roller itself as well as the immediately adjacent zones of the ones above Cell wheel lock 16 and the underlying current dryer 19 of deposits freed.
