Definitions

  • the invention relates to a method and an apparatus for treating tobacco in a conditioning medium, preferably in superheated steam.
  • Such devices are known from the prior art.
  • the treatment of tobacco with superheated steam is used to dry the tobacco.
  • all cut tobacco types ie for example also cigar inlay and cold cut tobacco impregnated with gas, be dried.
  • the tobacco Before drying, the tobacco usually expands with saturated steam instead. The expansion increases the filling capacity of the tobacco. The Subsequent drying of the tobacco further increases the filling capacity of the dried end product.
  • a known machine of this type for expanding and drying tobacco is from Hauni Maschinenbau AG under the product name "HDT hot steam dryer" distributed. This well-known plant and the expansion and drying of Tobacco with the help of saturated steam and superheated steam have in the Proven in practice.
  • DE 197 34 364 from Hauni Maschinenbau AG a method and an apparatus for applying a conditioning medium known on tobacco. This is used to expand the tobacco saturated steam used by a rotating Winnover roller with radial Steam nozzles that generate a rotating radiation curtain for the tobacco Fed tobacco. The Winnover roller continues to serve the expanded Tobacco through an adjacent opening into one of superheated steam flowed through the current dryer, in which he moisture to the emits hot steam used.
  • the object of the invention is therefore to provide a method and an apparatus for continue to develop in such a way that the resulting The end product is of even higher quality.
  • This object is achieved in that the residual gas content consisting of non-condensable gases in the conditioning medium in is kept approximately constant by the content of one of the non-condensable Gases, is regulated.
  • the invention includes the finding that the residual gas content - essentially Air - a conditioning medium containing preferably water vapor significant influence on the tobacco temperature in the dryer and thereby on the Tobacco expansion.
  • the degree of expansion is crucial Quality characteristic of the dried tobacco. Due to the preferred regulation of the Residual gas content via the regulation of the oxygen content, or not another condensable gas, e.g. Nitrogen and / or argon or other suitable Inert gas, the degree of expansion can now be found in the conditioning medium keep almost constant.
  • the proportion of the conditioning medium could be measured and regulated.
  • the preferred regulation of the oxygen content has the advantage that corresponding transducers are available relatively inexpensively and that Measurement behavior is very robust and can be implemented with little maintenance.
  • the composition of the residual gas can be assumed to be constant to a good approximation, so that the oxygen content forms a clear connection to the residual gas content.
  • Controlling the oxygen content is also advantageous because oxygen is chemical can react with the tobacco, especially at the described high drying temperatures, and a constant oxygen content therefore also a constant one Guaranteed product quality.
  • the residual gas content in the conditioning medium using the amount of conditioning medium in which the tobacco is located is regulated.
  • the invention includes the knowledge that the residual gas content, and in particular the oxygen content, the amount or pressure of the Conditioning medium depends.
  • the amount of conditioning medium is So particularly simple and advantageous as a manipulated variable for the residual gas content and the oxygen content can also be used.
  • Optimal conditions for expanding of tobacco are achieved when, according to a further embodiment Invention of the residual gas content only constant during the treatment of the tobacco is held.
  • a further preferred embodiment has the steps that a Desired residual gas content is specified in the conditioning medium that then the residual gas content is measured in the conditioning medium, that the measured residual gas content continues with the predetermined residual gas content is compared, when the measured residual gas content the desired Residual gas content exceeds, the amount of conditioning medium is increased, while if the measured residual gas content is the desired residual gas content falls below, the amount of conditioning medium is reduced.
  • the invention can be implemented particularly easily more preferred if the residual gas content in the superheated conditioning medium upstream of a tobacco feed point into the conditioning medium is measured. This allows short dead times in the control realize. It is further preferred if the residual gas content passes directly through Measurement of the oxygen content or one of the other non-condensable gases is measured in the residual gas, for example nitrogen.
  • the residual gas content regulated depending on the tobacco type. It is further preferred that Regulated oxygen content. This way it can meet the needs of different people Types of tobacco in relation to the optimal one for the degree of expansion of the end product Residual gas content in the overheated conditioning medium is taken into account become.
  • Another embodiment of the present invention is characterized in that that when a predetermined limit of residual gas content in the Conditioning medium the tobacco supply is stopped.
  • the limit lies here preferred at about 20%, since this value is the maximum, the expansion is not impairing portion is highlighted.
  • An oxygen content limit is further preferred predetermined, the exceeding stops the tobacco supply.
  • the temperature of the conditioning medium is regulated between 160 ° C and 300 ° C. This temperature range has proved to be optimal for carrying out the present invention.
  • the inventive device for performing the inventive The method includes a container for bringing together tobacco and superheated Conditioning medium, a supply valve for supplying the conditioning medium into the container, a drain valve for draining the conditioning medium out of the container and a measuring cell for measuring the residual gas content in the container.
  • the measuring cell is preferably between one on the container provided inlet point for the tobacco and the feed valve. On in this way the measuring cell can be undisturbed by the tobacco supply into the container work and thus reliably determine the residual gas content.
  • the measuring cell measures more preferably the oxygen content.
  • the only figure of the drawing shows a schematic diagram of an inventive Device 1 for performing the method according to the invention.
  • the core of the device 1 is a current dryer 2.
  • the tubular current dryer 2 is part of a closed, conditioning medium for drying the Tobacco in the circuit 4 contained in the current dryer 2.
  • a conditioning medium steam heated to about 200 ° C is used here.
  • To this Purpose is at the point marked with arrow 6 water vapor over a Feed valve 8 the circuit 4 and then a heater 10 with associated Burner 12 supplied. The supplied water vapor is in the heater 10 heated to the desired temperature of about 200 ° C.
  • the temperature of the superheated Water vapor in the current dryer 2 with the aid of a temperature sensor 18 detected.
  • the temperature recorded in this way is compared with the predefined one in a comparator 20 Target temperature of 200 ° C compared. Deviates from the sensor 18 measured temperature from the setpoint, then a with the comparator 20 connected actuator 22 via a line 24 a corresponding Command to the burner 12 to increase or decrease the temperature in the Given heater 10.
  • an oxygen sensor 26 the oxygen content in the superheated steam in the current dryer 2 measured and forwarded to a comparator and actuator 28.
  • the actuator 28 opens the control valve 8 to add additional steam according to arrow 6 into the circuit 4.
  • a rotary valve 34 for Feeding the tobacco according to arrow 36 into the current dryer 2 is provided downstream from the measurement of the temperature and the oxygen content is in in the immediate vicinity of the current dryer 2 .
  • the tobacco arrives according to arrow 38 via a groove 40 and through arrow 36 symbolized free fall into the rotary valve 34. From the rotary valve 34 the tobacco enters an expansion chamber connected to the rotary valve 34 42 funded.
  • the tobacco freely passes through a (not shown) rotating at about 200 revolutions per minute Winnover roller whose Pins (also not shown) projecting radially from the Winnover roller if necessary, dissolve clumped, contiguous tobacco fibers of the tobacco or individual. It hits in a preferred amount of 0.3 to 0.6 kg each kg of tobacco with a pressure of about 1 to 10 bar from the ends of the pins provided nozzle openings of a hollow shaft connected to the Winnover roller exiting and with its overlapping exit jets saturated steam forming a rotating jet curtain in the expansion chamber 42 on the falling tobacco and expands it by increasing the vapor pressure in the Inside the fibers as a result of the surface being released into the fibers penetrating heat of condensation.
