Embodiment 1

[0027] An application example of the method for accurately controlling moisture of the present invention in the drying link of shredded leaves and shredded stems of a silk thread. Such as Figure 8 As shown, the first moisture meter is set at the outlet of the silk dryer, and the second moisture meter is set at the outlet of the cooler. Due to the good accuracy of the moisture value detected at the outlet of the cooler, the detected moisture value is input into the control computer, and the moisture value required by the standard after cooling is calculated by PID to calculate the correction value, which forms the standard value of moisture at the outlet of the dried silk , compared with the moisture value at the outlet of the dried silk detected by the first moisture meter, and based on the comparison results, the PID calculation and control of the silk dryer is performed. Running effect analysis such as Figure 9 .

Embodiment 2

[0030] An application example of the method for accurately controlling moisture of the present invention in the leaf redrying link of a threshing and redrying line. Such as Figure 10 As shown, the first moisture meter is set at the outlet of the leaf roaster, and the second moisture meter is set at the outlet of the baler. Due to the good accuracy of the moisture value detected at the outlet of the baler, the detected moisture value is input into the control computer, and the moisture value required by the standard after packaging is calculated by PID to calculate the correction value, which forms the standard value of moisture at the outlet of the baking machine , and compare it with the moisture value at the outlet of the oven detected by the first moisture meter, and perform PID calculation and control on the oven machine according to the comparison result. Running effect analysis such as Figure 11 .

Abstract

The invention discloses a method for accurately controlling water content in tobacco processing. Two moisture meters are respectively arranged in the link of a cigarette primary production line or a threshing and redrying line with the demand of controlling the water content; the front moisture meter is arranged behind a tobacco dryer or a tobacco roaster, the rear moisture meter is arranged behind a cooling machine or a packaging machine, and the detection results of the two moisture meters are input into an electrical control system; the corrected value is provided for the front moisture meter by the water content value detected by the rear moisture meter in real time; and the front moisture meter can be used for controlling the operation of the tobacco dryer or the tobacco roaster according to the corrected result. The method can be used for obviously improving the stability and the accuracy of water content control of related equipment, overcomes the contradiction that the feedback speed and the detection data distortion degree are not considered by water content detection at the same time in the prior art, remarkably improves the water content control capability of equipment and reduces the fluctuation of moisture content.

Description

technical field [0001] The invention belongs to the technical field of cigarette shred making, and in particular relates to a method for accurately controlling moisture on a cigarette shred making line or a threshing and redrying line. Background technique [0002] At present, online moisture meters are widely used in various links of cigarette production for moisture control. However, during the process of leaf threshing, rebaking and silk making in cigarette production, the moisture content of materials in the drying, moisture regain, feeding and other links is constantly changing, which may cause relatively lagging feedback of moisture detection information, and the detection results are not accurate enough, thus affecting the moisture control of equipment stability and accuracy. There have been many related studies on the solution to the above problems, but the ideas are all based on the research and improvement of the control software and peripheral conditions under th...
