Problems solved by technology

[0005] At present, most tobacco factories in my country use random sampling static measurement methods to measure the filling value of shredded tobacco (see industry standards: YC / T152-2001 Determination of filling value of shredded cigarettes and YC / T163-2003 Determination of filling rate of expanded stalks in cigarettes), the instruments used It can only rely on manual sampling, static detection, individual samples taken per shift, static detection and analysis, and decision-making basis afterwards. The filling value of shredded tobacco measured by this method is relatively large, and it is far from being able to reflect the filling value of shredded tobacco in a timely and accurate manner. Variations in the process, more difficult to control
[0006] At present, there is only an online shredded tobacco filling value measuring instrument produced in Germany in the world. It uses two pressure rollers to press and measure the thickness of shredded tobacco on the conveyor belt, and uses an electronic scale to obtain the weight of all shredded tobacco on the conveyor belt. The thickness of shredded tobacco cannot accurately reflect the thickness of the entire shredded tobacco on the conveyor belt, and the weight of shredded tobacco weighed by the electronic scale is not only the weight of shredded tobacco pressed by two rollers, so the filling value of shredded tobacco measured by this measuring instrument has a large error
Other tobacco manufacturing enterprises in my country have also made improvements on the basis of this set of equipment, and further improved the pressure roller to increase the detection accuracy of the volume of cut tobacco when it passes through. , so online detection of cut tobacco filling has been unable to meet industry standards
[0007] Patents ZL200310121802.X and ZL200510086912.6 respectively applied for the method of measuring the filling value of shredded tobacco by using gamma rays and X-rays, but the rays have strong penetrating power and high energy, and the protection is difficult. If lost, it may cause personal injury
At the same time, the ray is only used to improve the accuracy of the detection volume during online detection, the detection process is still relatively complicated, and there are certain problems in the accuracy

Embodiment 1

[0031] Example 1 On-line measurement of filling value of shredded stems

[0032] according to figure 1 In the structure shown, a complete set of equipment for model establishment is set up at the online measurement point of the cut stem filling value, including a quantitative device 1 , a weighing device 4 , and a control processor 5 . The cut stem 2 to be tested passes through the quantitative device 1 and the weighing device 4 successively, and the flow rate of the cut stem 2 is V / T 0 , choose 330kg / h cut stems in this embodiment, take a certain time 30s as the detection interval, use a weighing device to take every second as a detection unit, constantly detect the instantaneous weight of cut stems, and record it as m 1 、m 2 ......m n ; Then get the average weight m within 30s 均 .

[0033] Define d as the filling value, laboratory test weight m 均 Corresponding stem filling value d, get d and m 均 The related formula, d=-1.5105m 均 +13.0830, wherein, the model coefficie...

Embodiment 2

[0039] Example 2 On-line measurement and moisture correction of shredded leaf filling value

[0040] according to figure 1 In the structure shown, a complete set of equipment for model establishment is set up at the online measurement point of the shredded filling value, including a quantitative device 1, an infrared moisture meter 3, a weighing device 4, and a control processor 5. The shredded leaf 2 to be measured passes through the quantitative device 1 and the weighing device 3 in sequence, and the flow rate of the shredded leaf 2 is V / T 0 , choose 4800kg / h shredded leaf in the present embodiment, take certain time 30s as detection interval, utilize weighing device to take every second as a detection unit, constantly detect the instantaneous weight and the instantaneous water content of shredded leaf, and record as m 1 、m 2 ......m n and S 1, S 2 ... S n ; Then get the average weight m within 30s 均 and mean moisture content S 均 .

Abstract

The invention relates to a tobacco processing technology, in particular to a method of measuring tobacco shred filling value on line by utilizing a weighting method. The technical problem solved by the invention is that the method can automatically measure the tobacco shred filling value on line, is stable, reliable and free of harm, and is simple, convenient and easy to operate, and has measuring accuracy. In order to realize the aim, the invention provides a method of measuring tobacco shred filling value on line, which can obtain the tobacco shred filling value by measuring the instant weight of tobacco shreds on line and utilizing the corresponding relationship between the weight or the variation and the filling value. The traditional method of measuring the tobacco shreds on line is overturned, and the tobacco shred filling amount can be conveniently, fast, stably and reliably measured accurately without harm.

Description

[0001] technical field [0002] The invention relates to a tobacco processing detection technology, in particular to a method for measuring the filling value of shredded tobacco online by using a weighing method. [0003] Background technique [0004] The filling value of shredded tobacco refers to the volume occupied by unit mass of shredded tobacco under the continuous action of a certain time and a certain pressure. The filling value of shredded tobacco is an important factor determining the consumption of shredded tobacco when making cigarettes, and it is also an important factor affecting the tar content, carbon monoxide content in cigarette smoke and the smoking quality of cigarettes. [0005] At present, most cigarette factories in my country use random sampling static measurement methods to measure the filling value of shredded tobacco (see industry standards: YC / T152-2001 Determination of filling value of shredded cigarettes and YC / T163-2003 Determination of fillin...
