Embodiment 1

[0015] The burley tobacco used in this embodiment is American burley tobacco single sheet tobacco B4F. American Burley tobacco single sheet tobacco B4F was used for leaf moistening and cutting into shreds, and the shredded samples were subjected to steam explosion with saturated water vapor as the working medium, the pressure was 0.5 MPa, and the pressure holding time was 50 seconds. Air-dry the leaf shreds after steam explosion to a moisture content of 19%. Re-feeding for dry ice expansion, the key parameters are: immersion time 22s, steam flow rate 750kg / h, hot air velocity 37m / s, hot air temperature 245°C. Burley expanded shredded tobacco with a moisture content of 13% was finally obtained. The physical indexes of regular shredded Burley tobacco, cut shredded tobacco treated with steam explosion, and expanded cut shredded Burley tobacco treated with steam explosion and dry ice expansion were measured, and the results are shown in Table 1. The expanded shredded burley toba...

Embodiment 2

[0024] The Burley tobacco used in this embodiment is Sichuan Dazhou Burley Tobacco Single Sheet Tobacco C3F. The Sichuan Dazhou Burley tobacco single sheet tobacco C3F was used for moistening and cutting into shreds, and the shredded samples were subjected to steam explosion with saturated water vapor as the working medium, the pressure was 0.45 MPa, and the pressure holding time was 50 seconds. Air-dry the leaf shreds after steam explosion to a moisture content of 20%. Re-feeding for dry ice expansion, the key parameters are: immersion time 32s, steam flow rate 900kg / h, hot air velocity 35m / s, hot air temperature 275°C. Burley expanded shredded tobacco with a moisture content of 12.5% ​​was finally obtained. The physical indexes of regular shredded Burley tobacco, cut shredded tobacco treated with steam explosion, and expanded cut shredded Burley tobacco treated with steam explosion and dry ice expansion were measured, and the results are shown in Table 3. The shredded burl...

Abstract

The invention discloses a method for improving usability of burley tobaccos by steam explosion and dry ice expansion. The burley tobaccos are low in grade and are wetted and shredded, wetted and shredded cut tobaccos are subjected to steam explosion, and finally, dry ice expansion is performed to obtain cut tobacco products. As the shredded low-grade cut burley tobaccos are subjected to steam explosion, internal chemical components of the cut tobaccos are improved, pungent taste and offensive odor of the burley tobaccos are removed, and the strength, the concentration and irritation of the burley tobaccos are reduced. The filling value of the cut tobaccos after steam explosion is reduced, and the filling performance of the cut burley tobaccos can be greatly improved by the aid of dry ice expansion. The usability of the low-grade burley tobaccos is greatly improved, compatibility of the cut tobaccos of the burley tobaccos and flue-cured tobacco leaves is enhanced, and the use ratio of the burley tobaccos is effectively increased.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to a processing method for burley tobacco. Background technique [0002] Burley tobacco belongs to light-color air-dried tobacco, and high-quality Burley tobacco is the main raw material of mixed cigarettes. Burley tobacco has very low sugar content, generally below 1%, high protein content, generally 18%-25%, high nicotine content, generally around 4%, and high ammonia content. Therefore, Burley tobacco has a strong taste, spicy but not mellow, heavy miscellaneous gas, irritating and vigorous, and usually has a strong protein and ammonia smell. In recent years, with the reduction of the output of blended cigarettes, there has been a large surplus of burley tobacco as a raw material for blended cigarettes. usage of. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a treatment method for improving the usability o...
