Problems solved by technology
Even now there are some schemes that imitate the principle of hand feeling, use the papermaking method to reconstitute tobacco leaves and measure the softness, but they all use larger-sized sheet tobacco materials, which are not suitable for the determination of the stiffness and flexibility of smaller-sized shredded tobacco

Embodiment Construction
[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0036] The present invention proposes an embodiment of a method for measuring the rigidity and flexibility of shredded tobacco, specifically, as figure 1 As shown, the following steps may be included:
[0037] Step S1, after filling the pretreated shredded tobacco sample into the sample cup, drive the platen to move downward according to preset parameters.
[0038] Specifically, the shredded tobacco sample to be tested can be placed in an environment with a preset temperature and relative humidity for a preset time to be pret...

The invention discloses a method and a device for measuring rigidity and flexibility of tobacco shreds. A to-be-measured tobacco shred sample is continuously pressed down, and pressure feedback and corresponding time of the pressing process from start to end are collected, so that mechanical properties of the tobacco shreds in a pressed process or in a grasping process in a rolling process are simulated, the rigidity and flexibility of the tobacco shreds reflecting the soft hand feeling or the hard hand feeling of the tobacco shreds are represented according to the relationship between the pressure data obtained in the pressing process and the corresponding time point, and the rigidity and flexibilityis taken as one of the quantitative indexes of the tobacco shreds. According to the method and device, the vacancy of tobacco shred quality evaluation indexes is filled, and important technical support and guidance are provided for continuous optimization and improvement of products.
Description
technical field [0001] The invention relates to the field of tobacco processing, in particular to a method and device for measuring the rigidity and flexibility of shredded tobacco. Background technique [0002] Tobacco industry usually uses physical characteristics indicators such as moisture content, filling value, cut tobacco structure, whole cut rate, conversion rate, purity and other physical characteristics indicators for the quality evaluation of finished tobacco. close, but there are still situations such as the shutdown rate and the amount of rejection in the rolling process are quite different. Based on this analysis, it can be considered that the existing quality evaluation indicators of finished tobacco cannot comprehensively and truly reflect the quality of tobacco and the applicable conditions of rolling. sex. [0003] For example, for cigarettes produced in the later stage, the stiffness and flexibility of shredded tobacco have a certain influence on the proc...
