Abstract

The invention discloses a method for constructing a tobacco leaf moisture content prediction model based on a rapid drying oven method, which comprises the following steps of: performing moisture determination on tobacco samples with the same moisture content according to a set drying standard and a preset rapid drying standard; determining the optimal drying time and drying temperature combination from the rapid drying test parameters by comparing the measurement results of different drying modes, and performing drying measurement by combining the samples with different water contents obtained by actual measurement with the optimal time and temperature combination on the basis of the optimal drying time and drying temperature combination; and according to the difference between the current water content value measured this time and the actually measured water content value, fitting an error relation curve, and combining the error relation curve with the current water content value to construct a water content prediction model based on the rapid drying method. According to the invention, the moisture content detection speed of the tobacco sample can be obviously improved, so that the moisture content measurement result is closer to the actual situation on an assembly line, and the moisture content index of the whole tobacco can be controlled.

Description

technical field [0001] The invention relates to the technical field of tobacco index detection, in particular to a method for constructing a prediction model of moisture content of tobacco leaves based on a rapid oven method. Background technique [0002] In the production process of the cigarette industry, the moisture content of tobacco is an extremely important indicator, which has a profound impact on the taste and final quality of finished cigarettes. Therefore, in the production process, the moisture content of tobacco at each process node is measured Detection is very necessary. In the actual production process, cigarette manufacturers usually test the moisture content of tobacco according to the national standard "2 hours at 100°C drying method" (that is, drying in an oven at a temperature of 100°C for 2 hours). [0003] The national standard "2-hour 100°C drying method" mainly uses an oven to dry tobacco samples, and then judges the moisture content of the tested t...
