Problems solved by technology

Tobacco leaves with heavy miscellaneous gases can only be used in low-grade cigarette formulas with a price below 6 yuan / pack. The shred drying process in the cigarette processing process removes a small amount of miscellaneous fumes by increasing the drying temperature, but it cannot effectively solve the problem of cigarettes. miscellaneous gas problem
At present, there is no good way to solve the problem of miscellaneous gases in tobacco leaves. Long-term storage and aging can only partially remove the miscellaneous gases of tobacco leaves. Some tobacco leaves of some origins and grades still have miscellaneous gases even after long-term storage and aging. Heavy, poor industrial usability and other issues, it is difficult to use in the formulation, resulting in a large backlog of tobacco leaves

Abstract

The invention belongs to the field of tobacco, and particularly relates to a method for removing offensive odor of tobacco leaves and improving the quality and the industrial availability of the tobacco leaves by processing the tobacco leaves by a negative pressure regulating method. The tobacco leaves are processed under the conditions of the vacuum degree of 0.010 to 0.098 MPa and the treatmenttime of 2 to 60 minutes; through controlling the process conditions of the vacuum degree, the processing time and the like, the offensive odor of the tobacco leaves can be well removed; and the quality and the industrial availability of the tobacco leaves are improved. The sensory evaluation results show that the processed sample tobacco leaves are greatly improved in aspects of aroma volume, offensive odor, aroma diffusivity, mouthfeel, aftertaste and the like; and the quality and the industrial availability are obviously improved. The tobacco leaves capable of only being used in a cigaretteformula at the price below 6 Yuan / packet can be used in a cigarette formula at the price about 10 Yuan / packet after being processed.

Description

technical field [0001] The invention belongs to the field of tobacco, and in particular relates to a method for treating tobacco leaves with a negative pressure regulation method, removing miscellaneous gases from the tobacco leaves, and improving the quality and industrial usability of the tobacco leaves. Background technique [0002] Tobacco raw materials are the foundation and guarantee of cigarette industry enterprises. New tobacco leaves need to be aged (alcoholized) before they can be used, and aging (alcoholized) can be divided into artificial aging and natural aging. The artificial aging time is short, and the effect is not good; the natural aging time is long, but the effect is good. At present, most of them are natural aging. The new tobacco leaves need to be naturally aged in the warehouse for more than one year before they can be used. The unaged tobacco leaves have green miscellaneous odors and prominent irritants, do not have the characteristic aroma of aged t...
