Embodiment 1
[0021] A method for measuring the spread rate of reconstituted tobacco leaves by a papermaking method, the specific steps are as follows:
[0022] (1) Dry the finished paper-making reconstituted tobacco leaves and the sample boxes in an oven at 90±1°C for 2 hours, then cool them in the desiccator for 30 minutes, and weigh the sample boxes respectively in m 0 =96.192g, papermaking reconstituted tobacco leaves m 1 =2.083g. The finished paper-making reconstituted tobacco leaves and sample boxes were dried in an oven at 90±1°C for 2 hours, and then cooled in a dryer for 30 minutes.
[0023] (2) Put paper-making reconstituted tobacco leaves in a sample box, cover them, soak them in water with a material-to-liquid ratio of 1g:500mL for 180s, take them out and dry them; then dry them in an oven at 90±1°C for 2 hours and then dry them. Cool in the container for 30 minutes, weigh m 2 =97.598g.

[0026] A method for measuring the spread rate of reconstituted tobacco leaves by a papermaking method, the specific steps are as follows:
[0027] (1) Dry the finished paper-making reconstituted tobacco leaves and 6 sample boxes in an oven at 90±1°C for 2 hours, then cool them in the desiccator for 30 minutes, and weigh the sample boxes respectively in m 0 .
[0028] (2) Weigh 6 parts of different weights of paper-making reconstituted tobacco leaves m 1 Put it in the sample box and cover it, soak each sample in water with two solid-liquid ratios of 1g:500mL at room temperature for 180s, take it out and dry it; then dry it in an oven at 90±1°C for 2 hours, then cool it in a desiccator for 30 minutes and weigh it m 2 . Measured m 0 、m 1 、m 2 The data are shown in Table 1.
[0029] (3) in m 1 is the abscissa, m 1 -(m 2 -m 0 ) is the ordinate, and the slope obtained by straight line fitting is the coating rate x=32.76%. like figure 1 shown.

Abstract
The invention discloses a measurement method of a coating rate for a paper-making reconstituted tobacco. The method comprises the following steps of: (1) drying a sample box and a paper-making reconstituted tobacco finished product, cooling the dried sample box and the dried paper-making reconstituted tobacco finished product in a dryer, weighing the sample box and recording the value as m0, and weighing the paper-making reconstituted tobacco and recording the value as m1; (2) placing the paper-making reconstituted tobacco in the sample box, soaking the sample box with the paper-making reconstituted tobacco in water twice, filtering the resulting product, drying the filtered product, cooling the dried product in the dryer, weighing the cooled product and recording the value as m2; and (3) calculating the coating rate x for the paper-making reconstituted tobacco: x=[m1-(m2-m0)] / m1*100%; or simultaneously carrying out step (1) and step (2) on a plurality of samples of the paper-making reconstituted tobaccos at different weights, and fitting a straight line by taking m1 as X-coordinate, m1-(m2-m0) as Y-coordinate to obtain a gradient, namely, the coating rate X. The measurement method of the coating rate for the paper-making reconstituted tobacco is simple, convenient, and capable of accurately and objectively measuring the coating rate of the paper-making reconstituted tobacco.
Description
technical field [0001] The invention relates to the technical field of detection of reconstituted tobacco leaves by papermaking method, in particular to a method for measuring the coating rate of reconstituted tobacco leaves by papermaking method. Background technique [0002] Papermaking reconstituted tobacco is a tobacco resource recycling product made from tobacco by-products and waste (tobacco stems, chips, and shreds, etc.) using improved papermaking technology combined with modern extraction and separation technology. The coating rate of reconstituted tobacco leaves refers to the percentage value of the absolute dry weight of the reconstituted tobacco leaf base dipping material to the absolute dry weight of the reconstituted tobacco leaves. dry weight] × 100%. Coating liquid is the most important carrier of soluble components and aroma components of reconstituted tobacco leaves. The level of coating rate directly affects the chemical components, physical indicators, s...
