example 1

[0025] Example 1. Take 2.0000g of shredded tobacco mixed evenly, and measure its initial moisture content according to the method of national standard GB5607-85. Take another 6.0000g of shredded tobacco and place it on the weighing module. The weighing module is placed at 22℃±1℃, relatively In the constant temperature and humidity module with a humidity of 60% ± 2%, the weight is measured every 300 seconds, and the reading is transmitted to the data analysis module. When the change is less than 0.0001g, the measurement is ended. The data analysis module automatically processes the initial moisture content and the obtained data to form a series of data points of instantaneous moisture content of cut tobacco with respect to time. The curve of the instant moisture content of cut tobacco with respect to time was made, and the slight difference in moisturizing effect of tobacco moisturizing agent was compared according to the comparison of the slope of the early stage of the curve a...

example 2

[0026] Example 2. Take 4.000g of shredded tobacco mixed evenly, measure its initial moisture content according to the method of national standard GB5607-85, and take another 8.000g of shredded tobacco and place it on the weighing module. The weighing module is placed at 30℃±1℃, relatively In the constant temperature and humidity module with a humidity of 80% ± 2%, the weight is measured every 600 seconds, and the reading is transmitted to the data analysis module. When the change is less than 0.001g, the measurement is ended. The data analysis module automatically processes the initial moisture content and the obtained data to form a series of data points of instantaneous moisture content of cut tobacco with respect to time.

example 3

[0027] Example 3. Take 6.00g of shredded tobacco mixed evenly, and measure its initial moisture content according to the method of national standard GB5607-85. Take another 10.00g of shredded tobacco and place it on an electronic balance. The electronic balance is placed at 10℃±1℃, and the relative humidity is 30 In the %±2% constant temperature and humidity module, the weight is measured every 900 seconds, and the reading is transmitted to the data analysis module at the same time, and the measurement is ended when the change is less than 0.01g. The data analysis module automatically processes the initial moisture content and the obtained data to form a series of data points of instantaneous moisture content of cut tobacco with respect to time.

Abstract

The invention relates to a method and a device for continuously measuring the moisture content of tobacco. The method is characterized by comprising the following steps: the initial moisture content of tobacco shreds is determined; the weight of the tobacco shreds is continuously measured under the environment of constant temperature and constant humidity; measured values are transmitted to a data analysis module which automatically processes the initial moisture content and obtained data, so as to form data points of the instant moisture content of a series of tobacco shreds with reference to the time; and a curve of the instant moisture content of the tobacco shreds with reference to the time is made, and the nuance of the moistening effect of tobacco humectant is compared according to the comparison of the slope coefficient in the earlier stage and the equilibrium moisture content in the late stage of the curve. The device comprises a climatic chamber, wherein the climatic chamber is provided with an air inlet and an air outlet; a weighing machine is arranged inside a chamber body, and is connected with the data analysis module which is arranged on the outside through a data wire; and the lower part of the chamber body is provided with a liquid storage tank. By utilization of the method and the device, the weight variation of the tobacco shreds can be monitored online in real time, and the difference of the moistening performance of the tobacco humectant can be compared by measurement of the nuance of the moisture content of the tobacco shreds, thereby providing scientific reference for evaluation of the moistening effect.

Description

technical field [0001] The invention relates to a continuous measurement method for tobacco moisture content, which can be used not only for the use of a continuous tobacco moisture content measurement device, but also for other similar material balance moisture content or moisture measurement, which is not only easy to operate, but also saves time and effort. Background technique [0002] As an important breakthrough and key technology to further improve the inherent quality of Chinese-style cigarettes and enhance the core competitiveness of Chinese-style cigarettes, cigarette flavor enhancement and moisturizing has been established by the State Tobacco Monopoly Administration as a major scientific and technological project in the tobacco industry. At present, various cigarette industrial enterprises are paying more and more attention to and attaching importance to cigarette moisturizing, and various basic and applied researches related to cigarette moisturizing have been ca...
