Abstract
The invention discloses a re-drying method for improving quality of re-dried tobacco laminas. Different drying curves and processing parameters are set to re-dry tobacco materials respectively according to characteristics of the tobacco materials on the upper portion, the middle portion and the lower portion and the moisture and the temperature of tobacco laminas entering a drying machine. According to the re-drying method, change trends of the drying curves are smooth, temperatures of zones of a drying section are lower than those of traditional machining, the mesh belt speed is low, and 'low-temperature slow-drying' can be achieved. Compared with a traditional machining method, the re-drying method has the advantages that the temperatures of zones of the drying section are low, and the mesh belt speed is low, so that leaves of re-dried tobacco laminas are bright and uniform in color and luster, elastic and loose in tissue structure; sensory quality indexes such as the aroma amount, dedicate degree, dopant gases, irritation and remaining taste are improved apparently; the quality of tobacco materials is improved, style characteristics and aroma characteristics of superior characteristic tobacco materials can be well maintained and manifested, and the industrial availability of tobacco materials is improved.
Description
Technical field
The invention belongs to tobacco material processing technique field, be specifically related to a kind of multiple roasting method improving redried quality.
Background technology
Traditional object of tobacco redrying mainly adjusts moisture content in leaves, is beneficial to tobacco natural alcoholization, improves quality of tobacco.What require raw tobacco material aroma characteristic along with cigarette enterprise improves constantly, and beating and double roasting it is also proposed higher requirement to redrying step process.Keep better and show that the aroma characteristic of high-quality characteristic tobacco raw material itself also becomes one of main purpose of redrying operation.Traditional redrying step process processes according to the optimum configurations of regulation in " tobacco threshing and redrying technological specification " (YC/T146-2001), because machined parameters set temperature is higher, cause the loss of tobacco leaf fragrance component own comparatively large, be unfavorable for the aroma characteristic better showing raw tobacco material.In addition, when smoked sheet enters roasting machine, moisture is higher, and temperature is scattered and disappeared too fast compared with high-moisture, easily cause leaf rolling degree to increase, and occurs making broken phenomenon, cause raw tobacco material to waste at precompressed packing process.Therefore, for redrying operation present situation, how to keep better while raising quality of tobacco and to show that the aroma characteristic of high-quality characteristic tobacco raw material has become problem demanding prompt solution in industry.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of multiple roasting method that effectively can improve redried quality is provided, while improving quality of tobacco, keep and show the aroma characteristic of high-quality characteristic tobacco raw material better.
Object of the present invention is achieved by the following technical programs.
Except as otherwise noted, percentage of the present invention is percetage by weight.
A kind of multiple roasting method improving redried quality, it is characterized in that: moisture, temperature when entering roasting machine according to the characteristic of each position raw tobacco material and sheet cigarette, formulate different baking curves, dryer section baking temperature and air inlet mode, the temperature in cool room, moisture and throttle opening and guipure speed respectively; Specifically comprise the following steps:
(1) according to blade construction, identity and oil content, tobacco leaf is divided into upper smoke, middle part cigarette and bottom cigarette;
(2) moisture, temperature when different parts sheet cigarette enters roasting machine is controlled, wherein: when top smoked sheet cigarette enters roasting machine, moisture, temperature control at 16.5% ~ 17.0%, 20 DEG C ~ 27 DEG C respectively; When middle part smoked sheet cigarette enters roasting machine, moisture, temperature control at 16.0% ~ 16.5%, 20 DEG C ~ 27 DEG C respectively; When bottom smoked sheet cigarette enters roasting machine, moisture, temperature control at 15.5% ~ 16.0%, 20 DEG C ~ 27 DEG C respectively;
(3) the sheet cigarette of different parts adopts different baking curves, wherein: 65 DEG C ~ 70 DEG C, upper smoke one district, and two 75 DEG C, districts ~ 80 DEG C, three 70 DEG C, districts ~ 75 DEG C, four 63 DEG C, districts ~ 67 DEG C; 59 DEG C ~ 65 DEG C, cigarette one district, middle part, two 68 DEG C, districts ~ 74 DEG C, three 64 DEG C, districts ~ 69 DEG C, four 56 DEG C, districts ~ 62 DEG C; 55 DEG C ~ 61 DEG C, bottom cigarette one district, two 66 DEG C, districts ~ 70 DEG C, three 62 DEG C, districts ~ 67 DEG C, four 54 DEG C, districts ~ 58 DEG C;
(4) the sheet cigarette of different parts adopts different cool room controling parameters, wherein: upper smoke temperature controls at 37 DEG C ~ 42 DEG C, and leaf water controls 9.5% ~ 10.0%; Middle part cigarette and bottom cigarette temperature control at 37 DEG C ~ 42 DEG C, and leaf water controls 10.0% ~ 10.5%; When the ambient humidity residing for sheet cigarette is greater than 60%, throttle opening controls 15% ~ 30%; When ambient humidity is less than 30%, throttle opening controls 80% ~ 100%; When ambient humidity is 30% ~ 60% time, throttle opening carries out Reasonable adjustment between 80% ~ 30%;
(5) the air inlet mode order in dryer section four districts is: lower air intake, lower air intake, lower air intake, upper air inlet, to ensure sheet cigarette uniform moisture;
(6) in whole redrying process guipure speeds control at 5.0m/min ~ 6.0m/min.
Tool of the present invention has the following advantages compared with traditional handicraft:
(1) redrying district temperature is low relative to traditional handicraft, and raw tobacco material fragrance matter loss is inherently relatively less, can better keep and show the aroma characteristic of high-quality characteristic tobacco raw material itself.
(2) in redrying district, leaf water scatters and disappears comparatively even, and leaf rolling degree reduces, and reduces at precompressed packing process broken rate, improves the utilization rate of characteristic sound tobacco raw material.
(3) tobacco leaf bright and evenly, oil content increases and high resilience, and institutional framework is more loose; Have clear improvement in organoleptic quality index perfume quantity, aroma quality, assorted gas, stimulation, pleasant impression etc.
(4) dryer section stone is divided into upper, middle and lower three layers.One, two, three districts adopt lower air intake to be that under main centering, synusia cigarette toasts, and adopt lower air intake can reduce stone density to a certain extent, are more conducive to removing the moisture in raw tobacco material.4th district adopt upper air inlet to be toast upper synusia cigarette, and upper air inlet can prevent online smoked sheet floating.
(5) in the guipure velocity interval of setting, not only sheet cigarette moisture can be controlled in claimed range, and the redrying time can be shortened as much as possible, scattering and disappearing of maximized minimizing sheet cigarette aroma substance.
