Tobacco shred elasticity detection method and tobacco shred elasticity detector

Abstract

The invention discloses a tobacco shred elasticity detection method. According to the method, the initial position of a tobacco shred pressing mechanism is constant, the moving distance in the pressing process is constant, the pressure height H<0> of tobacco shreds at a pressure application ending moment is constant, height L<0> covers tobacco shred filling values, tobacco shred elasticity obtained through calculation conceals defects of part of elasticity values, and the tobacco shred elasticity is reflected more accurately and truthfully. A tobacco shred elasticity detector comprises a base,a body, a measuring cylinder, the tobacco shred pressing mechanism, a tobacco shred height measuring mechanism and a detector control system, wherein the tobacco shred pressing mechanism comprises apressing head matched with the measuring cylinder, a sliding shaft and a driving mechanism, weights are arranged on the upper end face of the sliding shaft, and the driving mechanism drives the sliding shaft to move up and down at a constant speed; and the pressure of the tobacco shred pressing mechanism in the sample tobacco shred pressing process is adjusted through the weights, more comprehensive evaluation of tobacco shred quality is benefited, and technical support is provided for quality improvement and evaluation work of the tobacco shreds.

Description

technical field [0001] The invention relates to the technical field of tobacco physical quality detection, in particular to a method for detecting elasticity of shredded tobacco and an instrument for detecting elasticity of shredded tobacco. Background technique [0002] At present, the current indicators for evaluating the physical quality of shredded tobacco mainly include moisture content, filling value, and structure. Through the evaluation of these indicators, the processing and production of cigarettes are well guided. However, in the actual production process, we found that some batches of shredded tobacco with roughly the same physical indicators have a low shutdown rate during the rolling process, and the number of shorts removed is small, which is very useful; while other batches have a high shutdown rate during the rolling process. At the same time, we found that these "easy-to-use" shredded tobacco tends to be more elastic, while these "unusable" shredded tobacco...

Problems solved by technology

However, in the actual production process, we found that some batches of shredded tobacco with roughly the same physical indicators have a low shutdown rate during the rolling process, and the number of shorts removed is small, which is very useful; while other batches have a high shutdown rate during the rolling process. At the same time, we found that these "easy-to-use" shredded tobacco tends to be more elastic, while these "unusable" shredded tobacco is often stiff and inelastic. How to detect the elasticity of shredded tobacco? Tobacco industry standard "YC / T186-2004 Determination of Elasticity of Cigarette Shredded Tobacco" introduces a detection method for the elasticity of shredded tobacco. , the height L of the material after pressure is detected at the end of the pressure application 0 , the height of the material is L after the material is released for a certain period of time 1 , height L 0 Covering the filler value of cut tobacco, the formula E=(L 1 -L 0 ) / L 0 The obtained tobacco elasticity E covers part of the elastic value and cannot truly reflect the elasticity of tobacco, so it cannot be effectively popularized and applied.
