Embodiment 1

[0046]Honghe C3F sliced ​​tobacco, re-moisture to 15% water content and cut into shreds, and then carry out 5 times of grading and re-wet expansion, the first time make the water content of cut tobacco reach 25%, and store for 30 minutes; Store at 35% water content for 30 minutes; rake for the third time to re-moisture to 45% water content, store for 30 minutes; rake for the fourth time to re-moisture to 55% water content and store for 30 minutes; fifth time to rake and re-moisture to 60 % water content. After the moisture expansion is completed, put it into a 400×400×40mm mold and freeze it to -45°C, and quickly send the frozen shredded tobacco into the "microwave continuous freeze-drying system" for sublimation drying. It takes about 25 minutes to transport the tobacco to the outlet, and then the shredded tobacco that has been expanded and shaped by microwave at low temperature can be obtained. However, the moisture content of the shredded tobacco at the outlet is about 5% a...

Embodiment 2

[0048] Yuxi C3F sheet tobacco, re-moisture to 18% water content and cut into shreds, then carry out 4 times of grading and re-moisture expansion, the first time make the water content of cut tobacco reach 25%, and store for 30 minutes; Re-moisture to 35% water content, and store for 30 minutes; rake for the third time and re-moisture to 45% water content, and store for 30 minutes; re-moisture to 52% water content after the fourth rake. Put it into a rectangular mold of 400×400×40mm after re-wetting and swelling, and after freezing to -45°C, quickly send the frozen shredded tobacco into the "microwave continuous freeze-drying system" for sublimation drying. It takes about 23 minutes for the system to be transported to the outlet, and the shredded tobacco that has been expanded and shaped by microwave at low temperature can be obtained. But at this time, the moisture content of the shredded tobacco at the outlet is about 5%, and then it can be used in subsequent processes after i...

Embodiment 3

[0050] As the accompanying drawings of the present invention. The present invention can be implemented using a microwave continuous freeze-drying system. The microwave continuous freeze-drying system includes a microwave vacuum freeze-drying device, a vacuum water catcher, a vacuum feeding device, and a vacuum discharging device, wherein the microwave vacuum freeze-drying device includes a microwave generator 1, a microwave antenna 2, and an atmospheric pressure microwave cavity 4 , vacuum microwave cavity 5, vacuum partition 6, porous and breathable microwave shielding plate 7, low-loss conveyor belt 8, front-end vacuum microwave suppressor 9, rear-end vacuum microwave suppressor 10, characterized in that: in the microwave vacuum freeze-drying device A composite freeze-drying chamber 3 composed of an atmospheric pressure microwave chamber 4 and a vacuum microwave chamber 5 is provided, between the atmospheric pressure microwave chamber 4 and the vacuum microwave chamber 5 is ...

Abstract

The invention relates to a low-temperature microwave expansion process of cut tobacco. The process comprises the following steps of: putting expanded cut tobacco with the water content of 40-70 percent by rating resurgence in a die; then, freezing into blocks at a temperature of 55 DEG C below zero to 35 DEG C below zero; conveying the cut tobacco blocks into a microwave continuous freeze-dried system to sublimate and dry until the water content is 3-8 percent; and finally resurging to the water content of 12-13 percent to obtain a finished product of expanded cut tobacco. The cut tobacco is expanded by the process of the invention has the advantages of remarkable aroma and fragrance, lower breakage rate, remarkably lessened odor and controllable expansion degree.

Description

technical field [0001] The invention relates to a cut tobacco expansion process, in particular to a low-temperature microwave expansion process for cut tobacco. Background technique [0002] With the development of the concept of tar reduction and harm reduction in the tobacco industry and the implementation of technology, puffing tobacco raw materials has become an effective method. It can not only directly reduce the total amount of harmful substances in finished cigarettes, but also improve the full combustibility of cigarettes, thereby further reducing the generation of harmful substances in the smoking process. As shredded tobacco is the main material of cigarettes, its puffing manufacturing process and equipment have become a popular research object for major cigarette manufacturers and cigarette processing equipment manufacturers. There are three kinds of most representative shredded tobacco expansion methods at present. [0003] One is CO 2 Expansion method, the m...
