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 the tobacco material processing technique field, be specifically related to a kind of multiple roasting method that improves the redried quality.
Background technology
Traditional purpose of tobacco redrying mainly is that moisture content in leaves is adjusted, and is beneficial to tobacco natural alcoholization, improves quality of tobacco.Along with cigarette enterprise to improving constantly that the raw tobacco material aroma characteristic requires, beating and double roasting is also had higher requirement to the 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 be according to " tobacco threshing and redrying technological specification " (YC/T146-2001) in the regulation the parameter setting process, because the machined parameters set temperature is higher, cause the fragrance component loss of tobacco leaf own larger, be unfavorable for better showing the aroma characteristic of raw tobacco material.In addition, moisture was higher when smoked sheet entered roasting machine, and temperature is lost too fast than high-moisture, easily caused the leaf rolling degree to increase, and broken phenomenon occurred making at the precompressed packing process, caused the raw tobacco material waste.Therefore, for redrying operation present situation, how when improving quality of tobacco, keep better and show that the aroma characteristic of high-quality characteristic tobacco raw material has become problem demanding prompt solution in the 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 of energy Effective Raise redried quality is provided, when improving quality of tobacco, keep better and show the aroma characteristic of high-quality characteristic tobacco raw material.
Purpose 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 that improves the 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 respectively temperature, moisture and throttle opening and the guipure speed in different baking curves, dryer section baking temperature and air intake mode, cool room; Specifically may further comprise the steps:
(1) according to blade construction, identity and oil content, tobacco leaf is divided into upper smoke, middle part cigarette and bottom cigarette;
Moisture, temperature when (2) control different parts sheet cigarette enters roasting machine, wherein: moisture, temperature were controlled at respectively 16.5%～17.0%, 20 ℃～27 ℃ when top smoked sheet cigarette entered roasting machine; Moisture, temperature were controlled at respectively 16.0%～16.5%, 20 ℃～27 ℃ when middle part smoked sheet cigarette entered roasting machine; Moisture, temperature were controlled at respectively 15.5%～16.0%, 20 ℃～27 ℃ when bottom smoked sheet cigarette entered roasting machine;
(3) the sheet cigarette of different parts adopts different baking curves, wherein: 65 ℃～70 ℃ in upper smoke one district, 75 ℃～80 ℃ in two districts, 70 ℃～75 ℃ in three districts, 63 ℃～67 ℃ in four districts; 59 ℃～65 ℃ in Yan Yi district, middle part, 68 ℃～74 ℃ in two districts, 64 ℃～69 ℃ in three districts, 56 ℃～62 ℃ in four districts; 55 ℃～61 ℃ in Yan Yi district, bottom, 66 ℃～70 ℃ in two districts, 62 ℃～67 ℃ in three districts, 54 ℃～58 ℃ in four districts;
(4) the sheet cigarette of different parts adopts different cool room control parameters, and wherein: the upper smoke temperature is controlled at 37 ℃～42 ℃, and leaf water is controlled at 9.5%～10.0%; Middle part cigarette and bottom cigarette temperature are controlled at 37 ℃～42 ℃, and leaf water is controlled at 10.0%～10.5%; When the residing ambient humidity of sheet cigarette greater than 60% the time, throttle opening is controlled at 15%～30%; When ambient humidity less than 30% the time, throttle opening is controlled at 80%～100%; When ambient humidity 30%～60% the time, throttle opening is rationally adjusted between 80%～30%;
(5) the air intake mode in four districts of dryer section sequentially is: lower air intake, lower air intake, lower air intake, upper air inlet, and even to guarantee sheet cigarette moisture;
(6) guipure speed is controlled at 5.0m/min～6.0m/min in whole redrying process.
Compare the present invention with traditional handicraft and have following advantage:
(1) temperature relative traditional handicraft in redrying district is low, and the intrinsic fragrance matter of raw tobacco material itself loses relatively less, can better keep and show the aroma characteristic of high-quality characteristic tobacco raw material itself.
(2) in the redrying district, leaf water scatters and disappears more even, and the leaf rolling degree reduces, and reduces at precompressed packing process broken rate, improves the utilization rate of characteristic sound tobacco raw material.
(3) the tobacco leaf color and luster is vivid and even, and oil content increases and high resilience, and institutional framework is more loose; Have clear improvement at aspects such as organoleptic quality index perfume quantity, fragrance matter, assorted gas, stimulation, pleasant impressions.
(4) the dryer section stone is divided into three layers of upper, middle and lowers.One, air intake was that the synusia cigarette toasts under the main centering under two, three districts adopted, and adopted lower air intake can reduce to a certain extent stone density, more was conducive to remove the moisture in the raw tobacco material.It is that upper synusia cigarette is toasted that four districts adopt upper air inlet, and upper air inlet can prevent that online smoked sheet is floating.
(5) in the guipure velocity interval of setting, not only sheet cigarette moisture can be controlled in the claimed range, and can shorten as much as possible the redrying time, the scattering and disappearing of maximized minimizing sheet cigarette aroma substance.
