Tobacco leaf curing method based on image acquisition and moisture change

Abstract

The invention discloses a tobacco leaf curing method based on image acquisition and moisture change, which comprises the following steps: S100, respectively installing image acquisition devices on theside walls of a ceiling and a bottom shed of a curing barn, respectively hanging a tobacco leaf water loss rate measuring device on a ceiling cross rod and a bottom shed cross rod, and hanging a plurality of rods of tobacco leaves to be cured in a tobacco leaf hanging frame; S200, enabling the weighing sensor to obtain the mass of the tobacco leaves to be baked every 30 minutes, calculating the water loss rate of the tobacco leaves according to the obtained real-time mass of the tobacco leaves, enabling the image collecting device to obtain images of the tobacco leaves to be baked every 1 hour and correspondingly store the images and the water loss rate of the tobacco leaves according to the obtaining time sequence, and obtaining tobacco leaf image-tobacco leaf water loss rate data; and S300, obtaining the tobacco curing process according to the tobacco image-tobacco water loss rate data. The tobacco flue-curing process with a good overall flue-curing effect is obtained by accuratelymeasuring the change of the moisture content of tobacco leaves in a flue-curing barn, matching with a real-time image acquisition device and integrating image information and water loss rate information.

Description

technical field [0001] The present application relates to a tobacco leaf curing method based on image acquisition and moisture change, and belongs to the field of . Background technique [0002] Curing is an important link in the tobacco leaf production process, and it is also one of the bottlenecks restricting the development of flue-cured tobacco production and the improvement of tobacco leaf quality. The scientific and advanced baking process must be established on the basis of the tobacco leaf color, shape change and internal change law during the curing process, the correlation between the two changes, the controllable factors (temperature, humidity, ventilation, etc.) on the basis of changing relationships. [0003] Tobacco leaves of different quality types will have their own regularities in the changes of the above parameters during the curing process. The current traditional curing method is often based on experience, through manual on-site observation of tobacco ...

AI Technical Summary

Problems solved by technology

[0007] This application provides a tobacco leaf curing method based on image acquisition and moisture changes, to solve the problem of insufficient adaptability of the curing process to different types of tobacco leaves in the prior art for curing technical instructors and tobacco farmers The inaccurate judgment of the change caused a large loss in baking; the measurement accuracy of the water loss rate of the tobacco leaves in the existing flue-cured process is poor, which affects the drying process
