Near-infrared tobacco feeding homogeneity test device

Abstract

The invention provides a near infrared testing device of tobacco feeding uniformity which is characterized by comprising a light source, a splitter AOTF of an acousto-optic tunable filter light, an adjustable RF source, a fiber optic diffuse reflection probe, a reference light detector, a measuring light detector, a computer and a printer. The adjustable RF source is respectively and electrically connected with the AOTF and the computer; one end of the reference light detector is optically connected with the AOTF and the other end is electrically connected with an industrial computer; the fiber optic diffuse reflection probe is respectively and optically connected with the AOTF and the measuring light detector which is electrically connected with the industrial computer; the measuring light is projected onto the detected tobacco through the probe and is received by the measuring light detector through the diffuse reflection of the tobacco; the reference light detector and the measuring light detector respectively send the signals into the industrial computer for comparative analysis and processing to get feeding characteristics of the detected tobacco. The device has the outstanding advantages that the detected tobacco is not polluted; the physical characteristics of the detected tobacco are not destroyed; and the even degree of the feed solution which is sprayed on the tobacco can be quickly and automatically measured.

Description

technical field [0001] The invention belongs to the field of near-infrared testing, and in particular relates to a near-infrared tobacco leaf feeding uniformity test device. The device adopts near-infrared detection technology, and the detection and result display are all automatically completed by a computer. The detection method does not pollute the tested tobacco leaves. , does not damage the physical characteristics of the tobacco leaves to be tested, and can automatically and quickly measure the uniformity of the liquid sprayed on the tobacco leaves. Background technique [0002] Tobacco leaf feeding is generally carried out when the leaves are moistened. The leaves enter the leaf moistening drum, spray the feed liquid with steam, store the leaves, and make the feed liquid fully penetrate into the leaves. In order to improve the quality of tobacco, it is necessary to strictly control the uniformity of feeding, otherwise, some leaves will be insufficiently fed, which wil...
