Definitions
- the invention relates to a method for treating tobacco, in particular Burley tobacco, by applying casing and subsequent thermal treatment.
- casings are common steps in the processing of leaf tobacco before cutting.
- the aim of a casing treatment is to improve the processability and the taste properties of the tobacco material.
- Common components of casings are humectants such as glycols or glycerin, sugar and solid natural substances such as cocoa or licorice. High viscosity and the solids content of casings make it difficult to achieve a desired, uniform penetration of the tobacco material with the casing components.
- the heated casing is given together with a moistening by water and steam in aggregates known as casing drums.
- Burley tobaccos generally have relatively high levels of nitrogen compounds with low sugar levels. For this reason, an acceptable smoke taste can often only be achieved by using sugar-containing casings in combination with a subsequent thermal treatment.
- reaction products such as e.g. Pyrazines arise that contribute to the improvement of sensory quality.
- a belt dryer with several drying and cooling zones is used for the thermal treatment of casing-treated Burley tobacco, in which the tobacco is dried from approximately 30% initial moisture to approximately 5% moisture. For further processing, especially for cutting, the tobacco must then be moistened again to about 16% to 22%.
- Exposure intensity of the steam is not optimal. Furthermore, a lot of energy has to be used for the strong drying. Belt dryers also require a lot of space and, due to their design, lead to an inhomogeneous moisture distribution. Another disadvantage is the high fragility of the tobacco material when the humidity is below 10%, which leads to losses due to the formation of tobacco greens and dust.
- US 5 755 238 describes a method for rapid drying, cooling and rewetting with the aid of a multi-treatment the drying unit and the rewetting in a separate steam tunnel.
- the moisture of the tobacco material is approx. 30% before drying, approx. 5% before the steam tunnel and approx. 15% after rewetting.
- the hot air temperature of the dryer is approx. 105 ° C to 115 ° C and the total throughput time is approx. 60 seconds. Improved moisture homogeneity is to be achieved by using several fluidized bed drying zones.
- US 4 004 594 discloses a method for conditioning tobacco, in particular Burley tobacco, which provides impregnation of the tobacco particles with casing, a thermal treatment for expelling the nitrogen or the nitrogen compounds and the adjustment of the desired moisture content.
- the treatment system consists of a dosing unit, a casing drum, a preconditioning unit for treatment with steam and units for heating, cooling and rewetting the tobacco.
- the tobacco moisture levels after the dosing unit are 14% to 20%, preferably 18%, after the casing drum 30% to 42%, preferably 32%, after preconditioning approx. 35%, after heating 4% to 7% and after rewetting approx. 18% to 22%.
- a treatment with saturated steam of 2.5 bar to 3.5 bar takes place in the preconditioning unit, resulting in a tobacco temperature of approximately 70 ° C. in order to achieve an improved penetration of the casing into the tobacco leaf.
- US 3 402 479 describes a tunnel-like apparatus for the transport and treatment of nitrogen-rich tobacco with zones for predrying, for heating the tobacco without loss of moisture through the use of an appropriately conditioned medium and for cooling the material to be treated.
- the entry moisture of the tobacco material is 40% to 50%
- the temperature of the medium after predrying is approx. 100 ° C
- the discharge moisture is approx. 16% to 18%.
- the tobacco which is cased and has a moisture content of about 15% to 25% and which is generally in the form of leaf tobacco is subjected to an intensive steam treatment.
- the tobacco temperature is in a range from 80 ° C to 115 ° C, while the tobacco moisture is 15% to 25%.
- An intermediate step, which leads to a strong drying of the tobacco, does not occur in the method according to the invention.
- the steam treatment is preferably carried out in such a way that the tobacco is brought into intensive contact with the treatment medium over a period of 0.1 minutes to 10 minutes.
- the ratio of the mass flow rate of steam to tobacco is preferably set in a range from 0.1 to 0.5.
- the treatment is preferably carried out in a so-called steam tunnel.
- steam tunnel Such units are available, for example, from Sagemüller GmbH, Bockhorn or HAUNI Maschinenbau AG, Hamburg.
- saturated steam is preferably used with a pressure (before feeding into the steam tunnel) of 2 bar to 12 bar, particularly preferably from 4 bar to 10 bar.
- the moisture of the tobacco changes during the steam treatment depending on the choice of process parameters such as pressure of the steam and residence time (exposure time of the steam) by only a few percentage points.
- process parameters such as pressure of the steam and residence time (exposure time of the steam) by only a few percentage points.
- the tobacco treated according to the method according to the invention has a significantly more homogeneous moisture distribution than that which was treated according to the conventional method with a belt dryer.
- the tobacco treated according to the invention can be treated with medium-volatile aroma substances in the form of a so-called top dressing, which is preferably alcoholic, after steam treatment and cooling.
- the tobacco is then fed to the cutting process alone or after mixing with other types of tobacco without further dampening or drying steps.
- the effects of the aftertreatment can be changed to a greater extent without the discharge moisture (ie the tobacco moisture after the steam treatment) by changing the exposure time of the steam or correspondingly increasing the treatment temperature or the pressure of the steam to influence.
- an adaptation to the nitrogen content of the tobacco material can take place in this way, for example in order to expel smaller amounts of volatile nitrogen compounds in the case of low-nitrogen tobacco than in the case of nitrogen-rich ones, which in turn can lead to improved sensory results.
- a partially inverted aqueous saccharose solution was applied to both test tobacco in the same quantity and quality and subjected to thermal treatment in two test systems (example 1, example 2) in corresponding test systems. delt.
- the total sugar content before the thermal treatment was 10%.
- the so-called fluidized bed dryer (example 1) represents the application of a conventional method and is based on the principle of the vibratory conveyor with holes in the base plate through which hot air flows through the material to be treated.
- the initial moisture (entry moisture) of the leaf tobacco was a uniform 22%.
- the tobacco moisture was determined by drying the tobacco samples in unsealed aluminum cans with the aid of a calibrated convection oven at a temperature of 80 ° C for a period of 3 hours.
- Table 1 shows the hot air temperatures used, the corresponding dwell times and the discharge moisture (i.e. tobacco moisture after treatment in a fluidized bed dryer) of leaf tobacco.
- Example 2 The same base tobacco charged with partially inverted sucrose as in Example 1 was used. The initial moisture was 18%.
- a conventional steam tunnel with an oscillating conveyor was used as the treatment unit, in which hot steam (saturated steam) flowing out of holes in a base plate interacts with the leaf tobacco; basically there is atmospheric pressure in the steam tunnel (open system).
- the pressure of the steam before it was fed into the steam tunnel was approximately 7 bar and the mass ratio of tobacco to steam was 0.2.
- Table 2 shows the parameter combinations used.
- the tobacco temperature discharge and the discharge moisture are the tobacco temperature and the tobacco moisture immediately after the steam treatment.
- Tables 3 and 4 compare the results obtained for each of the two basic tobaccos examined according to parameter combinations 1 to 3 and 4 to 6 described in Tables 1 and 2. The content of total amino acids and ammonia were examined, each based on dry matter (TS). Table 3: Analysis data of treated Korean Burley
- the treated Burley tobacco was cut to prepare trial cigarettes and compared in pairs by an expert panel. In both cases, the comparison between the method according to the invention and the conventional method showed no significant differences.
