Embodiment

[0024] Using the TA.XT plus texture analyzer produced by British Stable Micro Systems, combined with the A / TG probe of the Tensile Grips series, the brittleness of the same batch of tobacco sheet samples with different moisture contents produced by a domestic thin sheet factory was measured. The specific implementation steps are as follows:

[0025] ① Selection of tobacco sheet samples

[0026] Tobacco sheet samples were unbroken, unwrinkled, uncut tobacco sheets taken from the sheet factory.

[0027] ②Temperature and humidity treatment of tobacco sheet samples

[0028] Condition and test the tobacco sheet according to the environmental conditions of temperature 22°C±2′C and relative humidity 60%±5% specified in GB / T 16447.

[0029] ③ Homogenization treatment

[0030] The homogenization treatment method is firstly to slowly freeze the tobacco sheet in an environment of -7°C to 0°C for 24 hours, and then quickly thaw it in an environment of 60°C to 70°C to room temperature. ...

Abstract

The invention provides a method for measuring brittleness of a tobacco slice prepared by a paper making method. The method is characterized by comprising the following specific steps: selecting a tobacco slice sample, performing temperature and humidity treatment on the tobacco slice sample, homogenizing the tobacco slice sample, cutting the tobacco slice into test samples with specified sizes, cutting a crack in each test sample, respectively fixing the two sides of the cut crack in the test sample into an upper fixture and a lower fixture of a Tensile Grips series probe, exerting a certain testing speed to each tobacco slice test sample by using a texture analyzer in a stretching mode, simulating a process of tearing apart the tobacco slice through stretching of the upper fixture and the lower fixture, and measuring the number of peaks of a force value in the process of tearing the tobacco slice for a certain distance or a certain time period so as to represent the brittleness. Through the measurement of the brittleness of the tobacco slice, the researching range of physical properties of the tobacco slice is expanded, the brittleness of the tobacco slice can be objectively and accurately represented, and a data support is provided for researching how to improve the quality of the domestic tobacco slice and improve the effective utilization ratio and the machinability of the tobacco slice in a cigarette producing process.

Description

technical field [0001] The invention belongs to the technical field of measuring physical properties of tobacco sheets by papermaking method, and mainly relates to a method for measuring the brittleness of tobacco sheets. Specifically, the texture analyzer is combined with probes of the Tensile Grips series (including A / TG, A / MTG, A / TGT, A / HDT, A / HDG, A / TGP, A / TGPHD probes) in tension mode Give the tobacco sheet sample a certain test speed, through the stretching of the upper and lower clamps, simulate the process of tearing the tobacco sheet, and measure the number of peaks (positive peak or negative peak) of the force value of the tobacco sheet during the tearing of a certain distance or time. ) to characterize its brittleness. Background technique [0002] Tobacco sheet by papermaking method is also called reconstituted tobacco leaf, which is defined as: according to the raw material formula requirements of reconstituted tobacco leaf, after soaking and extracting raw mat...
