A Method for Measuring the Filament Rate of Cut Tobacco Based on Similarity Coefficient

Abstract

The invention discloses a method for measuring the filament rate of shredded tobacco based on a similarity coefficient, which is suitable for the determination of the filament rate of shredded tobacco in the same formula component, and realizes the determination of the filament rate with high precision, high accuracy and low consumption. The rationality of the cigarette processing process and the control of the crushing rate of the shredded process are of great significance, and have a good prospect for industrialization and application.

Description

technical field [0001] The invention relates to a method for measuring the filament rate of shredded tobacco based on a similarity coefficient, which can effectively monitor product quality in the shredded tobacco processing process and belongs to the technical field of cigarette product quality monitoring. Background technique [0002] In the cigarette production and processing process of the tobacco industry and in the quality inspection of cigarette products, the inspection of the shredded tobacco structure is an important link. Among them, the filament rate of shredded tobacco can most clearly reflect the quality control and production of shredded tobacco during processing. The broken condition also directly affects the quality index of the coiling process. [0003] At present, in my country's tobacco industry standards, the structure of shredded tobacco is determined by random sampling of 4000g shredded tobacco, quartering method to reduce to 1000g, YQ-2 type vibrating ...

AI Technical Summary

Problems solved by technology

There is a certain deviation between the cut tobacco structure data obtained by this detection method and the precise process control required by the current tobacco industry. This detection method also has the following defects: (1), the measurement accuracy is low, and the balance system with a sensitivity of 1 / 10g The error is large, and the obtained data only retains one decimal place, and the obtained results cannot reflect the differences between different batches of shredded tobacco; (2), the sampling consumption is large, and each batch of shredded tobacco is normally sampled for 3-5 groups, consuming the value of shredded tobacco About 2,000 yuan; (3) The accuracy of this method is low. When the vibrating sieve is separated, there are situations such as missing shreds and entraining shredded tobacco, resulting in deviations in the separation of shredded tobacco; (4) The risk of sampling is relatively high, and it is limited to sampling consumption. Only 3 parallel samples are taken within 5 minutes for the first sampling test. For the production time of nearly 90 minutes in the entire production process, the number of samples taken and the time period covered are relatively small, and the risk of obtaining data is relatively high.
