Abstract
The invention discloses a tobacco leaf grading type loosening and conditioning method. According to the characteristics of incoming materials, performing graded loosening and moisture regaining on tobacco leaves by adopting a high-strength and low-strength matching mode; the first-stage loosening and conditioning aims at loosening the sliced tobacco leaves and removing part of miscellaneous gases, then the loosened tobacco leaves enter a second-stage loosening and conditioning procedure at a constant flow rate, and the shrinkage rate of the tobacco leaves is reduced and the moisture content is more uniform through the processing of the procedure; the tobacco leaves after loosening and moisture regaining enter a storage cabinet for temporary storage, so that the temperature and the moisture content of the tobacco leaves reach the specified process requirements, and conditions are provided for the subsequent processing of the tobacco leaves. The application of the invention obviously improves the loosening rate, the stretching rate, the water content uniformity and the sensory quality of the tobacco leaves.
Description
Technical field
The invention belongs to technical field of cigarette processing, be specifically related to a kind of tobacco leaf grading formula remoistening process.
Background technology
Loosening and gaining moisture of tobacco is one of important procedure in cigarette primary processing production process, and its process task is, makes the tobacco leaf after unpacking section loose, promotes tobacco leaf moisture content and temperature, increases the resist processing of tobacco leaf, and improves aesthetic quality.Tradition loosening and gaining moisture mode is mainly one-level formula loosening and gaining moisture, and its shortcoming main manifestations is: the physicochemical property otherness 1. due to supplied materials is comparatively large, and moisture content and the temperature fluctuation of traditional loosening and gaining moisture outlet material are larger; 2. after loosening and gaining moisture, tobacco leaf contacts with air, and the temperature difference is very large, causes crimp contraction to rise, is unfavorable for the processing of subsequent handling.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of tobacco leaf grading formula remoistening process is provided, according to the difference of supplied materials, the method of high and low two kinds of processing intensity collocation is adopted to carry out two-stage loosening and gaining moisture, tobacco leaf is heated more even in loosening and gaining moisture process, loosening ratio and rate of unfolding promote, and contribute to the aesthetic quality improving tobacco leaf simultaneously.
Object of the present invention is achieved by the following technical programs.
A kind of tobacco leaf grading formula remoistening process, it is characterized in that: be divided into by loosening and gaining moisture two-stage to carry out, wherein the ratio of adding water of first order loosening and gaining moisture is 3% ~ 5%, and material outlet moisture content is 17.0% ± 1.5%; The ratio of adding water of second level loosening and gaining moisture is 0 ~ 2%, and material outlet moisture content is 18.5% ± 1.0%;
The object of first order loosening and gaining moisture makes the tobacco leaf after section loose, gives the moisture content that tobacco leaf is certain, and it is broken to reduce in relaxing process making of producing, and the part simultaneously also can removing tobacco leaf is mixed gas; The object of second level loosening and gaining moisture mainly reduces the shrinkage of smoked sheet, and makes the moisture content of material more even.
First and second grade of loosening and gaining moisture all adopts drum-type loosening and gaining moisture.
The mass flow of second level loosening and gaining moisture is set to constant flow rate, and uninterrupted is 90% ~ 100% of equipment maximum productivity.
Tobacco leaf after two-stage loosening and gaining moisture enters storage cabinet and keeps in, temporary storage time 60 ~ 120min.
Compared with prior art, tool of the present invention has the following advantages:
1. keep in by entering storage cabinet after first order loosening and gaining moisture, the second level loosening and gaining moisture processing controlling mass flow and moisture regain, enable the abundant equilibrium moisture content of tobacco leaf and make the tobacco leaf mixture of different brackets more even, thus the fluctuation of tobacco leaf moisture content is diminished, be conducive to the carrying out of following process.
2. second level loosening and gaining moisture makes tobacco leaf temperature rise, and tobacco leaf after decreasing one-level loosening and gaining moisture is because meet the shrinkage phenomenon of cold formation from higher temperature.
3. add the moisture regain time of tobacco leaf, make tobacco leaf fully can absorb moisture content, reach the moisture content of technological requirement, and effectively eliminate tobacco leaf and to mix gas, improve tobacco aroma quality, maintain tobacco incense tolerance and improve the sweet sense of flue gas, thus reach the object promoting tobacco sensory quality.
Accompanying drawing explanation
