Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The present invention adopts the following method to make tobacco moisture detection standard samples: during the production and processing process, when the feeding grade is only the same grade in the same area, take samples in the smoke box at the packing pre-pressing place, remove the impurities from the samples, and separate the stems and leaves , remove the tobacco stems, take the leaves and pulverize them with a cyclone mill, and pass through a 3mm aperture sieve. After the sieve, the particle size below the specified particle size accounts for more than 95%. After mixing evenly with a sample divider, collect and seal it in a sealed container, and vent the air. After seven days to one month, the sample is fully mixed evenly, and the samples are tested separately in all ovens according to the "oven method", and then the mea...

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 ...
