Abstract
The invention relates to a method for expanding tobacco shred, which is characterized in that the method comprises the following steps: 1, pre-treating a tobacco shred raw material to ensure the water content thereof to be between 5 and 25 percent; 2, treating the tobacco shred in a container by reducing pressure to ensure the pressure to be not higher than 6kPa, introducing dimethyl ether vapor at a temperature between 10 and 50 DEG C into the container to raise the pressure to 400-1,200kPa, keeping the pressure for 10-30 minutes, and thoroughly soaking the tobacco shred by the dimethyl ether vapor; 3, under the condition of not breaking micropore structures of tobacco shred cells, reducing the pressure to close to atmospheric pressure; 4, injecting water vapor or other heated inert medium into the container to quickly raise the temperature in the container to between 100 and 150 DEG C to expand and mold the tobacco shred; 5, reducing the pressure in the container to 3kPa, readjusting the tobacco shred in vacuum, and adjusting the water content to 12-13 percent; and 6, communicating the atmosphere to raise the pressure in the container to the atmospheric pressure. The method can effectively preserve aroma containing substances in the tobacco shred and with high boiling point, the expanding effect of the tobacco shred is good, the fragmenting rate is low, the safety is high, and no pollution or residue exists.
Description
Technical field
The invention belongs to a kind of method of handling pipe tobacco, relate in particular to a kind of method that makes tobacco expanding.
Background technology
Expanded cut tobacco not only economizes in raw materials as one of cigarette composition raw material, has also improved the combustion position of pipe tobacco, the most important thing is to reduce or not perfume quantity when cigarette props up tar and carbon monoxide.
The method of expanded cut tobacco is a lot, and freon expansion is not because its dissolvent residual and problem such as damage the ozone layer are well solved, and this method is eliminated.That generally uses in the world at present has carbon dioxide, a nitrogen etc.High and the dipping decompression back pipe tobacco of the liquefaction pressure of carbon dioxide expanded technology freezes into piece, has determined complicated and expensiveization of its technology, and carbon dioxide expanded technological attrition greatly, equipment repair and maintenance cost height; The pipe tobacco fragrance loss is big, withered and burnt smell is heavy, flue gas drying, the broken rate height.Though the nitrogen expansion expansion temperature is low, pollution-free, noresidue, expansion rate is not high, because its pressure is too big, to the requirement of withstand voltage and the security requirement height of equipment.
In addition, United States Patent (USP) 5669397 and patent CN1099587A use propane as swelling agent, but its smell can influence cigarette odor-absorbing; The method that tobacco patent CN1210449A of kingdom and CN1099587A provide tobacco to expand under the high-pressure impregnation condition, the swelling agent isopentane of its use has low toxicity, and security is low.
Because pipe tobacco is easy to generate the chemical reaction of large amount of complex under high temperature and high pressure environment, the flavor matter loss of middle and high boiling point is big, and there is above drawback in traditional pipe tobacco expansion technique, thereby, be necessary to provide a kind of method of new expanded cut tobacco.
Summary of the invention
The purpose of this invention is to provide a kind of safe, pollution-free, noresidue, tobacco expanding is effective, makes the method for broken low expanded cut tobacco.
Method of the present invention may further comprise the steps:
1) tobacco raw material is carried out pre-treatment, make its moisture content 5%～25%;
2) in container pipe tobacco is carried out reduced pressure treatment, this pressure is not higher than 6kPa;
3) in container, feed 10 ℃～50 ℃ dimethyl ether steams, make pressure rise to 400kPa～1200kPa, the 10min～30min that keep-ups pressure makes the abundant tobacco shred immersion of dimethyl ether, under the condition of not destroying pipe tobacco cell microcellular structure, pressure is reduced near atmospheric pressure (local atmospheric pressure is to 150kPa);
4) in container, inject inert media (as nitrogen, carbon dioxide) after water vapour or other heating, utilize the heat of the inert media conduction of heat to make in the container temperature rise to 100 ℃～150 ℃ rapidly tobacco expanding finalized the design;
5) reduce container inner pressure to 3kPa, pipe tobacco is carried out vacuum adjust again, regulate moisture to 12%～13%;
6) connecting atmosphere makes container inner pressure rise to atmospheric pressure.
The invention has the beneficial effects as follows: pipe tobacco makes its moisture content reach 5%～25% expansion effect to obtain through pre-treatment.Liquid dimethyl ether occurs for avoiding the dimethyl ether steam to meet container inner wall, need in advance container to be preheated to 20 ℃～50 ℃.Container inner pressure preferably reduces to 2kPa～3kPa during decompression, about 2min～5min of time of decompression, take the air that reaches between pipe tobacco in the tobacco cell away as far as possible, be beneficial to the dimethyl ether steam and fully enter into cell, importantly do not allow liquid dimethyl ether to enter in the container in the present invention, and must guarantee that the dipping process dimethyl ether is with gaseous state mode tobacco shred immersion, container inner pressure is reduced near atmospheric pressure (local atmospheric pressure is to 150kPa), discharge unnecessary dimethyl ether steam simultaneously.In container, inject water vapour or other heated inert media (as nitrogen, carbon dioxide), utilize the heat of thermal medium conduction to make tobacco expanding, when temperature in the container reaches 100 ℃～150 ℃, stop to inject steam or other heated inert media behind expansion typing 10s～60s (as nitrogen, carbon dioxide), reduce container inner pressure fast to 50kPa, reclaim residual dimethyl ether steam simultaneously, continue then container inner pressure is reduced to 3kPa, pipe tobacco after expanding is carried out vacuum to be adjusted again, regulate about moisture to 12%～13%, connect atmosphere and make container inner pressure rise to atmospheric pressure.
Because pipe tobacco floods being not more than under the low pressure condition of 1200kPa, expansion temperature is not higher than 150 ℃, can effectively keep the flavor matter of middle and high boiling point in the pipe tobacco, and the tobacco expanding effect is good, makes broken low; Safe, pollution-free, the noresidue of employed swelling agent dimethyl ether; Expansion process realizes that easily system equipment is simple, easily realizes suitability for industrialized production.
