On one hand, the sensory quality of the product is affected, the smoking taste of the cigarette is flat when the water content is too large, the irritation is too large and the dryness is strong when the water content is too small, and meanwhile, the quality problems such as tobacco shred mildew and macula lutea are caused when the water content is too large; on the other hand, the water content also affects the breakage and loss of the product in the production process, if the water content is larger, the product has stronger processing resistance, otherwise, the product has weaker processing resistance, and the consumption in the process is larger. Therefore, the method is important for accurately controlling the water content in the process of making the silk.
Aiming at the problems, whether the use precision of the online infrared moisture meter meets the requirement or not is judged according to the following criteria: if the monitored moisture content of the product is more than or equal to 14%, the indication error is less than or equal to 0.5%, and if the monitored moisture content of the product is less than 14%, the indication error is less than or equal to 0.3%. The method for obtaining the indication error comprises the following steps: and (3) sampling tobacco product materials passing through the online infrared moisture meter, recording the display value of the moisture meter during sampling, detecting the moisture content of the same sample by adopting an oven method specified by GB/T22838.8 (measurement 8 th part of the physical properties of cigarettes and filter sticks: moisture content) to obtain a moisture content detection value, and comparing the display value of the moisture meter during sampling with the moisture content detection value to obtain an indication error. The obtaining process of the indication error is the checking process of the on-line infrared moisture meter.

And finally, comparing the display value of the online infrared moisture meter obtained in the second step with the water content detection value obtained in the third step, and then calculating the indication error of the online infrared moisture meter.
The sampling method adopts manual grabbing and sampling, and has the following defects: (1) in the whole grabbing process, the sampling personnel needs to display an interface of the online infrared moisture meter and determine the sampling position of the material at the required time, and a certain reaction time exists, so that the error between the tobacco material sample and the tobacco material sample detected by the actual probe is caused; (2) the difference of sampling frequency and sampling amount exists among different sampling personnel, so that the difference of tobacco material sample objects is easy to cause errors in the correction process; (3) the tobacco material sample passing through the probe of the online infrared moisture meter cannot be completely sampled, so that part of the sample main body is lost.
