Problems solved by technology

[0003] At present, most domestic and foreign tobacco industries use the feeding accuracy to judge whether the feeding is uniform, but in fact this is an indirect measurement method, which is the ratio of the mass of the liquid injected into the feeding drum to the mass of the smoke sheet entering the drum per unit time. Stability is only to evaluate the uniformity of feeding from a macro concept, which reflects the control ability of the feeding process, and cannot fully reflect whether the distribution of the feed liquid added to the surface of the smoke sheet is uniform
When it is necessary to improve the feeding process and feeding equipment, it is often judged whether the optimization has achieved results through artificial sensory evaluation and smoking of cigarettes made of tobacco sheets after feeding. This method has a large workload, is more disturbed by human factors, and has a large error

Embodiment Construction

[0020] The present invention is further described below in conjunction with embodiments, but does not limit the present invention.

[0021] The test object is the cigarette feeding process of a domestic cigarette enterprise production line.

[0022] 1. Detect the content of 1,2-propanediol in the raw material of tobacco leaves before feeding. No 1,2-propanediol was detected.

[0023] 2. At the outlet of the smoke feeder, take samples 30 times at equal intervals in accordance with the requirements of GB / T19616, and the sample amount is 30g each time.

[0024] 3. According to the requirements of YC / T 243-2008, the obtained smoke sample is dried at 40℃ and then ground into smoke dust. After passing through a 40-mesh sieve, the test sample is prepared. After random numbering, according to YC / T The 243-2008 standard method detects the content of 1,2-propanediol in the prepared samples, and the test results are shown in the following table:

Abstract

The invention relates to a method for determining the feed liquid application uniformity in a cigarette charging process, which is characterized by comprising the following steps: taking 1,2-propanediol in a feed liquid as a label, representing the distribution of the feed liquid in the tobacco flake by utilizing the content of the 1,2-propanediol in a tobacco flake after charging, and determining the uniformity degree of the charging through detection, calculation and statistical analysis. The invention provides an integral and objective method for the quantitative evaluation of the feed liquid application uniformity in the cigarette charging process, and the method has very important meanings for improving charging equipment and the charging process, and promoting the quality and the stability of cigarette products.

Description

Technical field [0001] The invention relates to a method for evaluating the uniformity of the application of the material liquid in the tobacco sheet feeding process in the production of cigarettes, and specifically relates to a method for quantitatively evaluating the uniformity of the material liquid application by detecting the distribution of the marker content in the tobacco sheet after the addition method. Background technique [0002] Tobacco chip feeding is an important process in the production process of cigarettes. Its task is to uniformly and accurately apply the material liquid to the tobacco chips according to the requirements of production and formula to achieve the purposes of flavoring, flavoring, moisturizing, mold prevention, and combustion. The uniformity of liquid application directly affects the sensory and physical quality of cigarette products, and then affects the sensory quality of cigarette products and the economic benefits of cigarette companies.
