Manufacturing of tobacco water content detection standard sample and oven calibration method

Abstract

The invention relates to a manufacturing method of tobacco water content detection standard sample and steps for applying to calibrate an oven, and is characterized in that, when the feed level is the same level in the same region only, the method comprises the following steps: sampling in the tobacco box at the packing pre-pressing place, removing the impurity from the sample, separating the peduncle leaves, removing the tobacco peduncle, taking the leaves and crushing through the whirlwind grinder, sieving, after mixing symmetrically by using the sampler, collecting in the sealed container,discharging the air, after a period of time, adequately symmetrically mixing the samples, respectively detecting the samples by all ovens according to the 'oven method', and then calculating the average water content rate of all detected samples, wherein the average valve is determined as the standard water content rate, the prepared sample is the standard sample, and the prepared standard sampleis used for calibrating the oven according to the oven method. The invention is capable of effectively standardizing and unifying the standard sample in the industry for water content detection and oven calibration, evaluating the accuracy of oven, and unifying the scaling range of oven in the industry, and generally improving the accuracy of oven in the industry and the stability for detecting the water content.

Description

technical field [0001] The invention relates to a method for making a tobacco moisture detection standard sample and a step or method for using it to calibrate an oven. Background technique [0002] Since the popularization of threshing and redrying technology, the tobacco processing and manufacturing industry at home and abroad has developed rapidly, and the detection methods and evaluation methods have become more and more perfect. Domestic and foreign customers have paid more attention to the detection of tobacco moisture. "Oven method" is the most classic method for determining the moisture content of tobacco leaves. It is not only widely used but also the only arbitration method for determining moisture content at present. However, due to the different testing conditions in various places, and the fundamental differences in the testing methods and results between the national standard and the international advanced standard, the test results are quite different. Since ...

Problems solved by technology

[0004] But so far, there is no domestic enterprise and unit that can independently produce standard samples, and there is no doubt that there is no important standard basis for the proofreading of the oven.
