Abstract
The invention relates to a method for improving the filling property of tobaccos such as shredded tobaccos or tobacco stems and tobacco additives. The method comprises the following steps: processing tobacco materials with the initial humidity of maximally reaching about 15 wt% by gas containing nitrogen and/or argon through a process of continuous or intermittent pressurization at first and then continuous or intermittent decompression under the pressure of 50 to 1,000 MPa, wherein the pressurization or decompression process is carried out in a high-pressure kettle or a plurality of tandem high-pressure kettles; finally performing post-heat treatment on the discharged tobacco materials. The method is characterized in that the pressurization process is carried out at the operating temperature of exceeding 55 DEG C, preferably 60-90 DEG C, and the initial humidity of the tobacco materials is 8-14 wt%.
Description
The present invention relates to one and improve tobacco, the method of the pipe tobacco such as shredded or offal and tobacco additive agent fillibility, wherein under the pressure of 50 to 1000 bar, in continuous or intermittent pressurized with subsequently continuously or under interval decompression, the tobacco-containing material of about 15 % by weight is reached with the process gas treatment start humidity be made up of nitrogen and/or argon gas, wherein said pressurization or decompression are carried out under autoclave or the connection at series system in multiple autoclave, and carry out after-baking to the tobacco-containing material drawn off subsequently.
Compared with adopting the tobacco pressure processing method of carbon dioxide, ammonia or VOC, verified this method (also referred to as INCOM-expanding method) is favourable.So the operating temperature that DE 31 19 330 A1 describes a kind of overwhelming majority in autoclave is such expanding method of 0 to 50 DEG C, wherein in order to improve fillibility or inflation level uses humidity be up to the tobacco-containing material of 15 % by weight and adopt steam to carry out post processing.The strong cooling of the tobacco-containing material to be drawn off desired by must producing according to the low tobacco humidity of 10 to 15 weight & during decompression here arranges.
In addition, DE 34 14 625 C2 discloses a kind of series-mounting, according to the method, although by different measures as in the cooling of pre-treatment gas of reactor air inlet, the cooling of autoclave or used and cold produce low operating temperature with the process gas of liquefaction when tobacco is flooded. the humidity of tobacco is random, and such as in the scope of 10 to 30 % by weight, but can require that the temperature of the temperature of autoclave or cooling water can not more than 50 DEG C clearly.
This puts the same branch DE relevant with the expanding method of series connection 39 35 774 C2 and confirms, wherein carries out by cooler the circulation processing gas, so that the low dipping temperature of 25 or 45 DEG C needed for maintaining.
Although adopt above-mentioned expanding method to obtain a good result improving in the fillibility of tobacco and swollen account grade, the cooling due to required autoclave and the cooling due to additional process gas its be quite expensive.
Task of the present invention is the INCOM-method improved up to now, and avoids being considered to so far obtain effect that is good equally or that improve in fillibility and expansion effect under being required with uneconomic cooling provision when pressurizeing.
Therefore, according to the present invention propose a kind of claims preamble limit start these class methods mentioned herein, it is characterized in that, pressurize under the temperature of reactor more than 55 DEG C, show astoundingly, under the low tobacco humidity reaching 15 % by weight, require that the instruction of low treatment temperature can not cause best expansion results up to now.And on the contrary, can obtain a good result in expansion and fillibility surprisingly by means of only raising treatment temperature when pressurizeing.
In addition, this also brings such advantage in technique, namely will pressurized heat amount not emit, that is without the need to the cooling of additional autoclave.
In the following embodiments, method of the present invention is described in detail by compared with prior art up to the present. result of the test represents that different operating temperature for different tobacco humidity is on the impact of inflation level.According to instruction up to now, under the tobacco humidity of 18 % by weight, improve operating temperature and expansion effect will be caused to worsen more than 40 DEG C.In contrast, when carrying out HIGH PRESSURE TREATMENT under the operating temperature of 60 and 80 DEG C, tobacco humidity lower than 15 % by weight time demonstrate and significantly improve effect. astoundingly, under the operating temperature of low tobacco humidity and rising obtainable inflation level sometimes even part exceed the value obtained under normal conditions.
Embodiment
Described HIGH PRESSURE TREATMENT is carry out in the use for laboratory autoclave of 2 liters in dischargeable capacity.Effect for the chuck of liquid medium circulation is the operating temperature needed for adjustment.Pressure increase is carried out from down, and upwards reduces when pressure reduces.Multiple valve makes the line map of expection become possibility. and the effect of forcing press regulates final pressure.The temperature of thermocouple measurement tobacco segment epimere.
For the use for laboratory device of after-baking by the ventilative woven wire as ribbon conveyer, for forming the guide plate of baccy fiber net, the steam jet with slit-like outlet and the steam pumping device arranged below this conveyer belt forms in required width. this post processing adopts saturated vapor to carry out.
Most important process parameter is listed in the table below in 1.
Table 1
Tobacco sample is spread out in flat plastic housing, and 21 DEG C and 62% relative humidity normal climate (Normklima) under adjusted. measure fillibility by means of Borgwaldt penetron, and specific volume be scaled ml/g (standard humidity 12 % by weight and 22 DEG C of normal temperatures under).According to formula below, calculate by untreated contrast sample or the data of basic pattern and the data of the sample of expansion the relative fillibility that also branch is called inflation level and improve, wherein F
brepresent fillibility and the F of basic pattern
erepresent the fillibility of expanding tobacco:
Δ%=(FE-FB)* 100%/FB
Bian is with 8 % by weight, 12 % by weight and 14 % by weight and carry out this test as the tobacco humidity of compare 18 % by weight. by constant temperature 40,60 and 80 DEG C of adjustment operation temperature of getting off. and final pressure is 700 bar, reduces pressure with the time interval of about 0.5 minute.All tests are based on the same mixture from Virginia tobacco (Virginiatabaken), and adopt saturated vapor to carry out described after-baking.
This test the results are shown in following table 2, contrast test the results are shown in following table 2a in this, in the table, T
arepresent with Δ %, the tobacco temperature (as discharge temp) just before taking out from autoclave represents that relative fillibility is improved or inflation level.
