Abstract

A tobacco information acquisition device based on near infrared spectroscopy comprises a support, a near infrared spectrometer, a control system for controlling operation of the near infrared spectrometer and a belt conveyor. The near infrared spectrometer is supported right above the belt conveyor through the support. A photoelectric sensor is arranged right below the belt conveyor, and the photoelectric sensor is positioned right below the projection of the infrared spectrometer on the belt conveyor. Through the device provided by the invention, real-time online acquisition of tobacco information can be finished effectively. Work efficiency is raised, and information assurance is provided for automatic grading of tobacco. Meanwhile, accurate internal information can be reliably grasped during tobacco grading by the adoption of the information acquisition device. The device provided by the invention has characteristics of greenization, speediness, lossless performance, multi-component analysis and the like. Thus, generality and subjectivity of tobacco information and man-made damage to tobacco during manual grading are avoided.

Description

technical field [0001] The invention relates to a tobacco leaf information collection device, in particular to a tobacco leaf information collection device based on near-infrared spectrum. Background technique [0002] Tobacco leaf is one of the main raw materials in the production of flue-cured tobacco products in my country. In order to ensure the quality of tobacco products and improve the economic value of tobacco products, it is usually necessary to classify the tobacco leaves purchased in the early stage, that is, to classify them according to grades, so as to ensure the quality of tobacco leaves. The quality of tobacco leaves mainly includes external quality and internal quality, and there is a certain relationship between the two. The grading of tobacco leaves is usually distinguished according to the quality factors such as maturity, leaf structure, identity, oil content, color, length and disability of tobacco leaves. Computer recognition technology and image pro...
