Method for controlling loosening and conditioning of tobacco leaves

Abstract

The invention provides a method for controlling loosening and conditioning of tobacco leaves. The method comprises the following steps of dividing the same leaf group formula into a plurality of processing modules according to the difference of the water absorption rate of each batch of flue-cured tobacco laminas to be processed; arranging corresponding channels, and setting water adding coefficients and the temperatures of moisture regaining water; utilizing an electronic belt scale to weigh the flue-cured tobacco laminas; setting the water adding coefficients, the temperatures of the moisture regaining water and moisture instrument channel numbers of the processing modules; calculating the water adding amount to carry out loosening and conditioning on the flue-cured tobacco laminas. According to the method for controlling loosening and conditioning of tobacco leaves, raw materials of the flue-cured tobacco laminas with similar processing performance in the leaf group formula are integrated into a single module, each batch of leaf group of each mark is formed by the multiple modules, and the corresponding processing parameters can be set according to the processing characteristics of the modules during production, so that the stability in the processing process is improved. The moisture instrument is calibrated in the loosening and conditioning procedure according to different processing characteristics of the modules during production, the corresponding channels are arranged, the measurement accuracy of the moisture instrument is improved, and the stability of the loosening and conditioning procedure in the processing process is improved.

Description

technical field [0001] The invention belongs to a tobacco processing method, in particular to a method for controlling the looseness and moisture regain of tobacco leaves. Background technique [0002] In the process of tobacco processing, it is necessary to loosen and increase the temperature and humidification of the tobacco sheet during the loosening and rehydration process, so as to increase the moisture content and temperature of the tobacco sheet to a certain level, so as to meet the technological requirements of subsequent processing. The traditional and commonly used cigarette loosening and moisture regain control method is as follows: the production process is produced in batches according to the brand, and the raw materials of each batch of sheet tobacco are randomly released from the warehouse according to the leaf group formula library. The loose moisture regain process is processed according to the order in which the tobacco leaves the warehouse, and the moistur...

AI Technical Summary

Problems solved by technology

[0003] The shortcomings of the existing system are mainly as follows: First, when each brand is produced in each batch, although the formula library is released according to the leaf group formula, the tobacco leaf grades in the same formula are randomly released according to the optimal path according to the scheduling system of the raw material formula library. Therefore, the rehydration process can only be processed according to the order in which the tobacco leaves are released from the warehouse. Because the processing properties of tobacco leaves of each grade are different, the moisture absorption characteristics and temperature increasing performance of tobacco leaves are different, resulting in large fluctuations in moisture outlet moisture and discharge temperature; the second is The infrared moisture meter used in the process of loose moisture regain is better for single substance measurement, but the tobacco raw materials in the leaf group formula are different due to different origins, grades, etc., and the moisture meter calibration can only be based on the whole The leaf group formula is calibrated, resulting in large errors in moisture measurement
