Abstract
The invention relates to a method for expanding cut tobaccos. The method includes firstly, using a plurality of organic solvents which are single or mixed according to different proportions, then subjecting specific chemical compositions of the cut tobaccos to gradient elution according to the sizes of polarities, and finally using dry ice to expand the cut tobaccos. According to the method for expanding the cut tobaccos, not only can the solvents with the different polarities be used for removing precursor chemical compositions of harmful ingredients which are probably produced during burning of the cut tobaccos, but also surface structures of the cut tobaccos can be modified and processed to a certain extent to improve permeability of an expanding agent in the cut tobaccos so that good effects of cut tobacco expansion are achieved. The expanding agent has the advantages of being appropriate in boiling points, safe, low in toxicity, easy to volatilize, simple in implement of technological conditions and the like.
Description
Technical field
The present invention relates to technical field of tobacco processing, specifically is a kind of method of tobacco expanding.
Background technology
In the middle of in the past 20 years, tobacco expanding has become important in a cigarette manufacture process link.Tobacco expanding can remedy the density and the volume of the pipe tobacco that loses in tobacco leaf storage and the baking process, and is the important part of many low tars and ultra-low tar cigarette.
Described in the tobacco expanding process in Fredrickson (U.S. No. 3524451) and Moser (the U.S. No. 3524452) patent, solvent impregnated pipe tobacco makes solvent evaporates to reach the effect of tobacco expanding through rapid heating then.Disclosed in Fredrickson (the U.S. No. 3683937) patent through heating or pressure and reduced rapidly, can make solvent get in the pipe tobacco with steam condition.Utsch (U.S. No. 4235250), Burde (U.S. No. 4258729), what all use in Sykes (the U.S. No. 4336814) patent is that dry ice comes expanded cut tobacco.In using the dry-ice expanding process, dry ice can be that gaseous state also can be liquid, at first lets dry ice be impregnated in the pipe tobacco, and heating makes tobacco expanding rapidly then.In known use dry-ice expanding pipe tobacco process; In order to make tobacco expanding continual and steady; Just must heat pipe tobacco, wherein excessive heat can damage the fragrance of tobacco and can make the part pipe tobacco become broken, and uses the pipe tobacco that can cause in the liquid dry ice tobacco shred immersion process flooding to produce the caking that contains dry ice; And these cakings just must be broken before heating, therefore will increase the complexity of expansion process.
In the domestic tobacco business traditional tobacco expanding agent of using be CFC-11 (Arcton 11); Its expansion process is that frozen state volatile materials CFC-11 is fully soaked with pipe tobacco; The pipe tobacco heating that to be soaked then; Cause the quick volatilization of said inflating medium, thereby the cell membrane that passes through its pipe tobacco makes tobacco cell return to volume and the shape that is had before the former harvesting to external diffusion; After PROCESS FOR TREATMENT such as moisture regain, but the pipe tobacco after expanding is processed the product that meets ordinary production and the best storage configuration.
Comprehensive above document and patent; Can find out now the tobacco expanding agent that great majority use, only have the function of expanded cut tobacco, yet along with the development of modern tobacco; Low burnt low harm cigarette has become trend of the times; Therefore, seeking a kind of swelling agent can either expanded cut tobacco, can extract precursor chemical composition specific in the part pipe tobacco again and improve the permeability of swelling agent in pipe tobacco and just become very important.
Summary of the invention:
The object of the invention is to provide a kind of method of tobacco expanding, and this method both can extract the specific precursor chemical composition in the pipe tobacco, can improve the permeability of swelling agent in pipe tobacco again, thereby reaches the method for better expanded cut tobacco.
The technical scheme of invention technical solution problem is: according to the polarity of different solvents; Proportioning goes out the solvent of opposed polarity; Obtaining the eluting solvent of different extracting powers, and, utilize dry ice to carry out tobacco expanding at last as swelling agent according to polarity size gradient wash-out pipe tobacco.Concrete grammar is following:
Press polarity size gradient sequentially eluting pipe tobacco with eluting solvent earlier, described eluting solvent polarity size gradient is: n-hexane, acetone, ethanol; Perhaps n-hexane+acetone is 10～20:1, acetone, ethanol; Perhaps n-hexane+ethanol is 10～20:1, acetone, ethanol; Eluting temperature is 18～30 ℃, and the time is 1～4 hour, pipe tobacco is expanded as swelling agent with dry ice afterwards.
In n-hexane, add an amount of acetone or alcohol; Make the modification of pipe tobacco eluting solvent; Not only have the expansion function, can also extract chemical composition specific in the pipe tobacco, in their pyrolysis produces in combustion process harmful components of to a certain degree minimizing; Improve the permeability of swelling agent in pipe tobacco again, thereby improved expansion effect.
The employed bloating plant of method of the present invention is basic identical with the swelling agent equipment that uses CFC-11, and the technological process of expansion is also basic identical.
Use above three kinds solvent gradient elution pipe tobacco respectively; Pipe tobacco puts into that saturated back quality is m1 in the climatic chamber before the wash-out; Pipe tobacco puts into that the quality after saturated is m2 in the climatic chamber after the wash-out, utilizes following formula to calculate every kind of combination wash-out and finishes the permeability variation situation of pipe tobacco afterwards.
The permeability variation situation sees the following form after calculating three kinds of eluting solvent gradient elution pipe tobaccos according to above formula:
| ? | Eluting solvent 1 | Eluting solvent 2 | Eluting solvent 3 |
| Permeability % | 28.32 | 22.56－16.32 | 11.56－7.89 |
In the table: eluting solvent 1 is n-hexane, acetone, ethanol; Eluting solvent 2 is that n-hexane+acetone is 10～20:1, acetone, ethanol; Eluting solvent 3 is that n-hexane+ethanol is 10～20:1, acetone, ethanol.
The precursor chemical composition of issuable harmful components when method of the present invention not only can utilize the removal of solvents pipe tobacco of opposed polarity to burn; Can also carry out to a certain degree modification and processing to the pipe tobacco surface texture; Improving the permeability of swelling agent in pipe tobacco, thereby reach the effect of better expanded cut tobacco.This swelling agent has that boiling point is suitable, safety, low toxicity, volatile, process conditions realize characteristics such as simple.
