Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0023] For the current leaf moistening treatment, it is mainly to set the corresponding temperature and humidity according to different parts of the tobacco, which has a certain effect on increasing the rate of large and medium slices and reducing the rate of stalks, but it does not improve the aroma of the tobacco, and it requires high equipment and is practical. Sexual problems. The invention provides a leaf moistening method for maintaining the neutral aroma substances of flue-cured tobacco. Compressed air is used to atomize the water, and a lower temperature and higher humidity are used to moisten the leaves. While meeting the requirements of the leaf threshing process, it can effectively retain The aroma su...

Abstract

The invention discloses a leaf moistening method for keeping neutral aroma substances of flue-cured tobacco, which comprises the following steps: before feeding, preheating a leaf moistening cylinder for 6-9 minutes, and introducing hot air; when feeding is started, using compressed air for atomizing moisture, spraying the atomized moisture to the tobacco strips, and performing leaf moistening treatment at least twice, wherein in the first-time leaf moistening treatment, the temperature ranges from 37 DEG C to 47 DEG C, the moisture content of outlet materials ranges from 18% to 20%, the inclination angle of a leaf moistening cylinder is adjusted to range from 3.5 degrees to 4.5 degrees, and the leaf moistening time ranges from 7 min to 9 min; and in the second-time leaf moistening treatment, the temperature is 40-50 DEG C, the water content of an outlet material is 19%-21%, the inclination angle of the leaf moistening cylinder is adjusted to 3.5-4.5 degrees, and the leaf moistening time is 7-9 min. According to the leaf moistening method for maintaining the neutral aroma substances in the flue-cured tobacco, moisture is atomized through compressed air, the leaves are moistened at the low temperature and the high humidity, the requirement of the threshing process is met, meanwhile, the aroma substances in the flue-cured tobacco strips can be effectively kept, loss of the neutral aroma substances in the flue-cured tobacco strips is reduced, and the threshing quality, the quality of finished tobacco strips and the industrial usability are further improved.

Description

technical field [0001] The invention relates to the technical field of cigarette raw material processing, in particular to a leaf moistening method for maintaining neutral aroma substances in flue-cured tobacco. Background technique [0002] With the full use of sheet tobacco, threshing and redrying has also become an important link in the cigarette industrial production. The purpose of the threshing redrying process is to separate and redry the tobacco leaves and tobacco stems, which plays an important role in the formula and quality of silk making. With the continuous improvement of cigarette companies' requirements for the aroma characteristics of tobacco raw materials, higher requirements are also put forward for the threshing and redrying process. How to effectively reduce the loss of aroma substances and better maintain the aroma characteristics of high-quality raw materials has also become the threshing and redrying process. one of the requirements. [0003] Neutral...
