Preparation method of cut tobacco moisture gradient experiment sample

Abstract

The invention discloses a preparation method of a cut tobacco moisture gradient experiment sample. According to the preparation method, cut tobacco samples of different outlet moistures are obtained by adjusting the set values of the flow of cut tobacco leaves, wherein the determination method of the flow of the cut tobacco leaves comprises the steps of establishing a mathematical model of the flow of the cut tobacco leaves, the moisture of the incoming material, the moisture of the outlet, and HT or SIROX moisture adding and standard work water removal points; determining the moisture of theincoming material, the HT or SIROX steam working pressure, the temperature of a drying cylinder body, the temperature of the drying hot air, and the value of HT or SIROX moisture adding and standard work water removal points; and enabling the moisture of the incoming material and the HT or SIROX moisture adding and standard work water removal points determined in the step two to be substituted into the mathematical model established in the step one, and working out the flow of the cut tobacco leaves corresponding to different outlet moisture. According to the method disclosed by the invention,the technical problem in preparation of a plurality of outlet moisture experimental samples in one batch is solved under the condition that the temperature of a KLD-2 drying cylinder body and the hotair temperature are not changed.

Description

technical field [0001] The invention belongs to the technical field of shredded tobacco in the tobacco industry, and in particular relates to a method for preparing shredded tobacco samples when detecting the moisture index of shredded tobacco. Background technique [0002] In the tobacco industry, companies have been controlling shredded tobacco as a key processing link. Among them, the "moisture index of shredded tobacco" is a key index in the control focus. The impact on the quality of cigarettes is the most significant. Different cut tobacco moisture will not only affect the appearance quality, physical indicators and stability, sensory quality, and conventional smoke of cigarettes to varying degrees, but also in the research on the quality index of "burning head". It is also found that moisture has a certain relationship with the "fire out" indicator. [0003] In the field of brand shred quality, research on optimal cigarette moisture usually adopts comparative test me...

AI Technical Summary

Problems solved by technology

[0004] One is that the water coverage of the two gradients is small, and the representativeness of the selected indicators is not strong;

[0005] The second is that there are many steps in the processing process, there are many variables, and the uncertainty brought about by human operation, there are more or less differences in the stability of the two groups of tobacco leaf processing.

This method can realize shredded tobacco with multiple moisture gradients, but it also has certain disadvantages: first, it is difficult to control the relative humidity and the equilibrium time of the environment used to balance the moisture of shredded tobacco; The third is that in the preparation of the sample, due to the thickness of the sample accumulation, the moisture in the surface, middle and bottom layers of the cut tobacco that is discharged from the balance cannot be consistent
