Problems solved by technology

[0006] The purpose of the present invention is to provide a method for measuring the ratio of shredded stems in shredded tobacco to solve the problems in the prior art that the visual inspection method can only pick out about 85% of the actual added amount, the detection accuracy is low, or the method used in shredded leaves or shredded stems Apply a certain coloring agent in the tobacco, and then calculate the proportion of this substance in the shredded tobacco through optical comparison. The operation is complicated, the cost is high, and it causes a lot of shredded tobacco to be scrapped.

Embodiment Construction

[0021] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the present embodiment provides a method for measuring the proportion of shredded stems in shredded tobacco, comprising the following steps:

[0023] Step 1: Take 5-10g, preferably 10g, of shredded tobacco at the outlet of the silk storage cabinet, and after drying, accurately weigh and record it as M;

[0024] Step 2: Put the dried shredded tobacco into a storage tank of 200-500mL, preferably 250mL, with a density of 0.47-0.93g / cm 3 , preferably 0.68g / cm 3 In a glass beaker of acetone, fully stir with a glass rod and let it stand for 1 minute, and filter off the floating matter in the upper layer of the solution;

[0025] Step 3: Take the components of the lower layer of the solution, filter and dry them, and put the dried lower components into a storage tank of 200-500mL, preferably 250mL, with a density...

Abstract

The invention provides a method for determining cut stem proportion in cut tobacco. The method comprises the steps of: separating cut stems from cut tobacco according to density difference, drying and weighing the cut stems and calculating stem tobacco. The method for determining cut stem proportion in cut tobacco employs density difference to separate cut stems, and has simple and quick operation, high accuracy and strong practical applicability. The method can evaluate and verify whether the cut stem proportion meets the requirement of a blending technology in actual production process and whether the blending mode is reasonable, and can solve technical problem of mixing uniformity difference of cut stems of different specifications. The method for determining cut stem proportion in cut tobacco solves the problems of accuracy and speedability in determination of cut stem mixing proportion in cut tobacco of tobacco enterprise, and provides a feasible method for accurate and rapid detection of cut stem mixing proportion in cut tobacco, and has great significance for control of the production process stability, optimization of blending mode and improvement on stem silk production parameters.

Description

technical field [0001] The invention relates to a method for measuring, in particular to a method for measuring the ratio of shredded stems in shredded tobacco. Background technique [0002] As a formula component in shredded tobacco, shredded stems have the advantages of increasing the filling value of shredded tobacco, reducing consumption, reducing the amount of tar in cigarettes, and providing support for the fullness of cigarettes. It has a great influence, and then affects the stability of cigarette smoking and tar. In order to find opportunities for improving the blending stability of cut stems, study the distribution of cut stems in cut tobacco, optimize control and improve process conditions, it is necessary to determine the ratio of cut stems in cut tobacco. [0003] At present, the methods for determining the proportion of shredded stems in shredded tobacco are: [0004] 1. The method of visual inspection, select cut stems from a certain amount of shredded to...
