Embodiment 1

[0040] refer to figure 1 , a kind of rapid testing method for the preparation accuracy of flavorings for tobacco, comprising the following steps:

[0041] Step 1, collect the image of the color area of ​​the standard liquid test paper

[0042] Based on the production formula, the fragrance monomers are weighed and prepared according to the formula ratio requirements. The weighing accuracy is two decimal places when preparing, and the prepared material solution is fully stirred (60min) and heated to 60°C. Dip the material liquid, put it on the pH test paper, and use the shooting equipment to collect the image of the color area within 3s;

[0043] Step 2, use HSV for image quantization

[0044] Quantify the hue H, saturation S, and lightness V of the collected color images, exclude the S value and V value affected by the shooting equipment and the environment, take the hue H value to establish a standard material-liquid comparison library, and calculate each According to the ...

Embodiment 2

[0054] According to Step 3 of Example 1, the H value database of the standard feed liquid was established.

[0055] The results are shown in Table 1:

[0056] Grade 1 Grade 2 Grade 3 Grade 4 Grade 5 Grade 6 Grade 7 Grade 8 Grade 9 standard median 30.23 28.38 34.22 31.64 38.37 24.68 35.29 30.95 29.06 Tolerance ±0.01 ±0.01 ±0.04 ±0.01 ±0.02 ±0.05 ±0.01 ±0.01 ±0.01

Embodiment 3

[0058] According to Example 1, the rapid inspection of the preparation accuracy of tobacco flavors was carried out, and the results of the rapid inspection from April 1, 2019 to April 9, 2019 were counted.

[0059] The results are shown in Table 2:

Abstract

The invention discloses a quick detection method for the tobacco flavor preparation accuracy. According to the method, based on the color development reaction principle of pH test paper, image color quantization is conducted by using a machine vision technology (an HSV algorithm), the precision of the quick detection method is improved, the problem that feed liquid in a production field cannot bequickly detected is solved, and a new method is provided for on-site quality control. The method comprises the following steps that an image of a test paper color development area of standard feed liquid is collected; by using the HSV, image quantization is conducted; a standard feed liquid H value database is built; production sampling is conducted, and an H value is calculated; according to a CDmethod, and abnormality judgment is conducted; by using an SPC method, reinspection is conducted.

Description

technical field [0001] The invention is applicable to the herb tobacco industry system, and specifically relates to a rapid inspection method for the preparation accuracy of flavorings for tobacco. Background technique [0002] In the production of tobacco industry, flavoring agent for tobacco is an indispensable flavoring agent, which is used for spraying and flavoring on the surface of tobacco leaves to improve the aroma characteristics of tobacco leaves and reduce the difference in leaf grades. Leaf feeding is an important production process in the tobacco industry. [0003] The preparation of flavors and fragrances for tobacco is made of various monomer fragrance bases according to the proportion of the formula and weighed by the operator. The following errors are prone to occur during the preparation process: 1. Replacement of monomers; 2. Wrong weighing of monomers; 3. Stirring uneven. The above mistakes or operational errors will cause the feed liquid to fail to mee...
