Method for improving percent of pass of cut stem moisture by controlling added water of stem moistening machine

Abstract

The invention discloses a method for improving percent of pass of cut stem moisture by controlling added water of a stem moistening machine. The method for improving the percent of pass of cut stem moisture by controlling the added water of the stem moistening machine comprises the following steps of enabling numerical values of environmental temperature, environmental moisture, time for storage in a stem storage cabinet, the added water of the stem moistening machine and the moisture content of the cut stems from the process of stem moistening to the process of stem cutting to be in a group and collecting a plurality of groups of the numerical values; performing multi-element linear regression analysis on a regression equation through the plurality of groups of numerical values; detecting the significance of the above regression equation and the significance of an obtained regression coefficient under the given significance level; transforming the regression equation and obtaining the added water of the stem moistening machine with the moisture content of the cut stems serving as a determinate target value. The method for improving the percent of pass of cut stem moisture by controlling the added water of the stem moistening machine can rapidly and efficiency control the added water of the stem moistening machine and improve the percent of pass of the cut stems.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a method for increasing the qualified rate of cut stem moisture by controlling the amount of water added to a stem moistening machine. Background technique [0002] The processing of shredded stems mainly includes the processes of soaking stems by steeping machine, moistening stems by moistening machine, storing stems in storage cabinets, and cutting shredded stems. Cut stem moisture is an important indicator in the cigarette processing and production process. In the tobacco manufacturing industry, cut stem moisture is a very important factor in the production process of silk thread, which determines the softness, plasticity and processing resistance of cut stems. It affects the smoking quality and physical and chemical properties of cigarettes. If the cut stem moisture is too high, it will increase the energy consumption of the subsequent drying process and the cost of the ent...

AI Technical Summary

Problems solved by technology

Many tobacco processing enterprises have no constant temperature and humidity control in the stem storage cabinets. At the same time, the moistened tobacco stems need to be transported and stored in the workshop. When the tobacco stems are stored for more than 4 hours in a dry season, it is easy to cause the tobacco stems in the stem cabinet to be damaged. Water is lost, and there is no specific control method for setting the amount of water added to the moistening machine, which often leads to a low moisture pass rate of cut stems, which affects the pass rate of cut stems moisture and the processing quality of dried stems
