The compression and decompression is carried out either in an autoclave or in several autoclaves arranged in the form of a cascade. The invention is characterised in that the thermal aftertreatment of the extracted tobacco material is carried out by means of a flowing, heat-transferring medium consisting of a mixture of permanent gases and superheated steam, the proportion of permanent gas being kept constant at a value between 10 and 60 vol. %.
Description
The present invention relates to a kind of method of the improvement filling capacity of tobacco as described in the preamble according to main claim.
The expanding method of INCOM, described in DE3119330A1, DE3414625C2 and DE3935774C2 verified the fillable that improves tobacco can aspect be successful.In these methods, said tobacco is an original water content up to the tobacco leaf or the offal of about 30% chopping, they are under the effect of 50 to 1000 processing gases crust, that be made up of nitrogen and/or argon gas at pressure, through pressurizeing continuously or carrying out pressurized treatments stage by stage, reduce pressure continuously subsequently or reduced pressure treatment stage by stage.Pressurization and depressurization steps can carry out in a pressure pan, also can carry out in a plurality of pressure pans of several series connection.Then, the tobacco-containing material that draws off is heated post processing, in the heating post processing, expanding tobacco, and therefore the fillable of tobacco can increase.
With compare with the method for carbon dioxide, ammonia or volatile organic compound pressurized treatments tobacco, the method of INCOM is proved to be advantageous, handle tobacco because use carbon dioxide, ammonia or volatile organic compound, the undesirable dissolving that has been bound to of fragrance in the tobacco-containing material or nicotine, perhaps the residual gas in tobacco-containing material is known from experience the taste that disturbs tobacco, or finally can be because when using carbon dioxide, the dry ice that is drawn off by decompression can consume a lot of energy.
Consider the INCOM method of being mentioned, DE3119330 has described such expanding method, the operating temperature of this method is 0 ℃ to 50 ℃ in pressure pan, and the moisture of the tobacco-containing material of employing is up to 15wt.-%, and carries out post processing to increase fillable energy or dilation with water vapour.In addition, DE3414625C2 and DE3935774C2 disclose Cascading Methods, the low operating temperature in the tobacco dipping process by tobacco pack into cooling processing gas before the reactor, realized by the cooling pressure pan or by using cold-peace liquefaction to handle gas.
In these known methods, be 0.5 to 10kg/m with density
3Steam carries out hot post processing, preferably uses saturated vapor, perhaps uses the hot-air up to 440 ℃.
Though from EP484899B1, can learn under about 30 crust of pressure, with the method for carbon dioxide treatment tobacco, in the method, hot post processing is to send into tobacco in the high-temperature steam or send in the gas that contains 50-95vol.-% steam, the heating tobacco carries out in 200 to 350 ℃ the flow media, sends into a little downstream tobacco and uses the water of low temperature or the steam temperature with the minimizing flow media.The flow media that utilize to conduct heat is dried to moisture to be about 2 to 3wt.-% tobacco and to be adjusted to normal moisture again.After the tobacco decompression with the carbon dioxide pressurized treatments, dry ice forms on tobacco, although dry ice has high evaporation enthalpy, and in order to carry out the hot post processing of tobacco, necessary Fast Heating tobacco, this will cause strong heat and/or mechanical stress to tobacco.
Under based on INCOM method situation of the present invention, compare with tobacco with carbon dioxide treatment, the tobacco of handling with nitrogen and/or argon gas needs the energy of much less to come gas that desorb absorbs and expanding tobacco relatively thus, so with regard to the INCOM method, opposite with method with carbon dioxide treatment, on the taste of tobacco, there is not harmful effect.In addition under the hot post processing situation of the tobacco of handling with nitrogen and/or argon gas, heat is to transmit on the tobacco that is condensate in cooling by water vapour, and in follow-up hot last handling process, reaches the required moisture of expanding tobacco by drying.
But the method for INCOM also exists and makes tobacco cross wet or risk of overheating, and the result is owing to the subsiding of honeycomb of expanding lost the fillable energy.
The objective of the invention is in the INCOM method, the tobacco of handling with nitrogen and/or argon gas is carried out hot post processing, to obtain having the even product quality of best filling capacity.
In order to reach this purpose, therefore a kind of method according to the main claim preamble has been proposed, the method is characterized in that: the flowing heat transfer medium of using the mixture by permanent gas and superheated vapour to form carries out hot post processing, and wherein the proportions constant of permanent gas remains in the scope of 10-60vol.-%.
Permanent gas herein is meant when drying any gas that can use with steam, as air, also can mix with nitrogen and/or argon gas or other inert gas in case of necessity.
Beyond thoughtly be, for reach best fillable under the given operating condition and in the dry run that particularly flowing can value, the ratio of the permanent gas in being mixed with the mixture of superheated vapour is a major parameter.
The preferred main air that uses is controlled the ratio of air indirectly as permanent gas by the content of measuring oxygen.The AIR Proportional of flowing heat transfer medium preferably accounts for 20 to 50vol.-%, particularly accounts for 25 to 40vol.-%.
The temperature of heat transfer medium is preferably at 120 to 300 ℃, and before hot post processing, the humidity of the tobacco that pressurized treatments is crossed should be 8 to 25wt.-%, and after hot post processing, the humidity of tobacco suits in 8 to 15wt.-% scope in addition.
In the particularly preferred embodiment of the inventive method, when hot post processing, dry known principle is implemented the introducing of vapours in closed system according to flowing, wherein the downstream of the vapours sent in the discharging zone of heat treatment tobacco of permanent gas infeeds, and in closed circulation after expanded tobacco cooling and drawing off, under situation, circulate with the constant rate of other water vapour adjusting permanent gas.At this moment to reduce the temperature of tobacco fast especially, and therefore the fillable of tobacco can be fixed.
Hereinafter, with reference to schematic diagram shown in Figure 1, explain the method for optimizing process of using conventional mobile drier, wherein air is as permanent gas, and its ratio is measured indirectly by oxygen content.
According to the local pressure reduction between heat transmission medium that imports in circulation and the environment, extraneous air sucks in the zone of inlet (1) and discharge port (2), and steam is discharged by steam flap (3).Superheated steam is sent into by steam valve (4).Oxygen content in heat transfer medium is measured with probe (5).By steam regulation valve (4) and steam flap (3), can regulate required oxygen content, and therefore permanent gas and superheated steam are transferred to constant ratio.
The following example shows the fillable energy and the relation between the ratio of permanent gas in heat transfer medium.For reaching best fillable energy, the ratio of required permanent gas depends on the type of used tobacco-containing material and the boundary condition of moisture and equipment in each situation.
Embodiment
According to the method for INCOM, the tobacco of handling is carried out following hot post processing with mobile drier shown in Figure 1.The tobacco flow amount of sending into is 1250kg/h, and the volume flow of the circulation heat transfer medium that is formed by superheated steam and air is 7315m
3/ h.Ratio by measuring steam that oxygen content derives and permanent air is changed by the firm power of heater, the firm power of heater is corresponding to 1.3,7.5 and the oxygen content grade of 15vol.-%, this ratio corresponding to permanent gas is 6.5 or 37 or 75vol.-% and in 185 to 165 ℃ of scopes, and the relevant reverse of the initial temperature of measuring before sending into tobacco changes.
Fillable that draw off and the tobacco through regulating can be measured by the penetron of Borgwaldt, and converts specific volume under 22 ℃ of rated temperatures and specified moisture 12wt.-% ml/g.The data computation of the sample expanded that never comprises the fundamental test data of permanent gas and handle with the heat transfer medium that steam and permanent gas form go out relative fillable can improvement:
Δ %=(F
