Apparatus and method for non-invasive measurement and determination of the moisture and the density of the bulk and packaged tobacco

摘要

(57) is measured by the moisture contained in large chunks of material (14) such as tobacco leaf bulk material or, [Abstract] tobacco bail (12) on and microwaves are used, the internal structure a method and apparatus that can be used for. Microwave radiation source (28), is located on one side of the cigarette tobacco, such bail, the antenna (30) is arranged on opposite sides of the bale. It propagates through a portion of the bail, radiation source beam (32) is generated signals (38) and is received by a receiving antenna (36). Moisture of that portion of bale and the signal is used to determine the overall uniformity of the bail. Methods and apparatus in addition, described herein may also be used when measuring tobacco leaf loose bulk, moisture leaf tobacco, for example through the silo. Furthermore, in the method of analyzing the internal structure of the tobacco packaged, it was confirmed that the early detection of the presence or absence of contaminants or foreign matter in the tobacco within the package by analyzing the internal structure, the tobacco material is present throughout the entire package possible. The structure data is collected from reflected microwave receiving and / or analysis for determining the moisture is performed for it. Detection for the analysis of uncorrected data classification, data structure of the uncorrected, and parsed using a decision algorithm or /. Preferably, the data analysis, microwave multiple frequencies through the package of cigarettes with a characteristic non-uniformity and / or contaminants or foreign particles is indicated as a term "contaminating component" collectively herein is made based on the pair (42) of the phase shift (44) attenuation obtained by. This unique way, detection and classification of the sample, classification is possible in conjunction with the precision and accuracy of detection and a high level of non-uniformity and Contaminant components and / or especially in general.
