Abstract
The invention discloses a threshing and redrying method for reducing the CO release amount. The threshing and redrying method mainly comprises a threshing air separation working procedure and a tobacco redrying working procedure, wherein a hot air leaf moistening working procedure is added before the threshing air separation working procedure, namely the hot air leaf moistening working procedure is executed after a primary moistening working procedure and a secondary moistening working procedure are executed; the temperature in the hot air leaf moistening is 80-120 DEG C. According to the threshing and redrying method, the hot air leaf moistening working procedure is added before the threshing air separation working procedure, therefore, on the premise of keeping the style of cigarettes, the CO release amount in smoke can be effectively reduced.
Description
Technical field
The invention belongs to raw material of cigarette manufacture field, be specifically related to a kind of beating and double roasting method of the CO of reduction burst size.
Background technology
CO is one of important environmental contaminants, it is generally by producing containing C material imperfect combustion, its mechanism of toxication is mainly affinity 200-300 times that the affinity of CO and hemoglobin exceeds oxygen and hemoglobin, therefore CO is easy to be combined with hemoglobin, form carbonyl haemoglobin, thereby hemoglobin is lost take ability and the effect of oxygen, cause tissue to suffocate.CO is to all toxic effects of the histocyte of whole body, and it is particularly serious on corticocerebral impact.
State Tobacco Monopoly Bureau has printed and distributed " State Tobacco Monopoly Bureau is about the notice of further propelling lowering harm and decreasing coking work " (No. (2006) 412, domestic cigarettes section) on June 16th, 2006, and to lowering harm and decreasing coking, work has proposed new requirement.This notice is using 7 kinds of harmful components of the cigarette smoke including CO as the important indicator that characterizes cigarette mainstream flue gas biohazardous, show that by measurements and calculations cigarette Evaluation of Harmfulness index weighs the security of cigarette.
For further promoting the enforcement of the strategic problem of tobacco business lowering harm and decreasing coking, advance Harm reduction techniques to fall carrying out in a deep going way of burnt work, State Tobacco Monopoly Bureau has printed and distributed " State Tobacco Monopoly Bureau is about the suggestion of further propelling lowering harm and decreasing coking work " (No. (2008) 471, domestic cigarettes section) on August 27th, 2008, clearly propose, by 2010, whole nation cigarette is being obtained remarkable breakthrough aspect 7 kinds of harmful components such as elective reduction CO, forms and a collection ofly has the core technology of independent intellectual property right and be applied in industry focus shaft cigarette brand.And think and should strengthen raw tobacco material, Cigarette processing technique and the impact research of auxiliary material design on harmful constituents in cigarette flue gas burst size, for lowering harm and decreasing coking application technical research and low harm product development are provided fundamental basis.
How to reduce the CO content in cigarette mainstream flue gas, reduce the harm of smoking to health, the tradition research of this respect mainly concentrates in the investigation of materials of cigarette " three paper one rods ", filter stick technology and ventilation dilution technology, but this class technology is in reducing CO, also reduce TPM and tar content in flue gas, directly affected cigarette smoking quality and satisfaction.Also have in recent years much about the new material research and the research of throwing technology that reduce CO burst size.The patent of invention that is 201210239310.X as Chinese Patent Application No. has proposed the cigarette paper that a kind of application contains rice paper paper pulp fiber, wherein can effectively reduce CO content in cigarette mainstream flue gas.
Existing beating and double roasting technology mainly focuses on improving tobacco leaf physical arrangement after beating and double roasting, chemical composition uniformity etc., is conceived to process with Recipe leaf beating with aesthetic quality or similar the homogenizing of routine chemical components.Utilize at present tobacco threshing and redrying processing technology not paid attention to reduce CO burst size in cigarette smoke, also have no relevant patent and bibliographical information, therefore, a kind of beating and double roasting method that reduces CO burst size in cigarette smoke, CO burst size in reduction cigarette smoke is moved forward to the beating and double roasting stage by the method, guaranteeing under the prerequisite of raw tobacco material product style have important value for improving safety cigarette, to Harm reduction techniques, work has proposed a kind of new thinking.
Summary of the invention
The object of this invention is to provide a kind of beating and double roasting method of the CO of reduction burst size, the method can effectively reduce the CO burst size in cigarette smoke after beating and double roasting, controls CO burst size from the raw material of cigarette.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:
Reduce a beating and double roasting method for CO burst size, mainly comprise wind dispensing operation and smoked sheet multiple roasting operation, increase hot blast leaves moisting operation before wind dispensing operation, i.e. hot blast leaves moisting operation is after a profit, two profit operations, and the temperature of hot blast leaves moisting is 80～120 ℃.
In order further to reduce the CO burst size in tobacco leaf, the fight each other parameter of leaf wind operation break-down of the present invention has been carried out following optimization, and the technological parameter of described wind dispensing operation is as follows:
Upper tobacco leaf: a dozen rotating speed 675r/min, the two fast 565r/min that spin, the three fast 655r/min that spin, the four fast 715r/min that spin, the five fast 645r/min that spin;
Middle part tobacco leaf: a dozen rotating speed 540r/min, the two fast 510r/min that spin, the three fast 620r/min that spin, the four fast 730r/min that spin, the five fast 615r/min that spin;
Lower tobacco leaf: a dozen rotating speed 470r/min, the two fast 460r/min that spin, the three fast 630r/min that spin, the four fast 670r/min that spin, the five fast 600r/min that spin.
In order further to reduce the CO burst size in tobacco leaf, the present invention has carried out following optimization to the parameter of smoked sheet multiple roasting operation, and the technological parameter of described smoked sheet multiple roasting operation is as follows:
Upper tobacco leaf: guipure speed 36Hz, 77 ℃ of dry district's temperature, 87 ℃ of dry two district's temperature, 67 ℃ of dry three district's temperature, 61 ℃ of dry four district's temperature;
Middle part tobacco leaf: guipure speed 42Hz, 63 ℃ of dry district's temperature, 86 ℃ of dry two district's temperature, 63 ℃ of dry three district's temperature, 57 ℃ of dry four district's temperature;
Lower tobacco leaf: guipure speed 38Hz, 64 ℃ of dry district's temperature, 81 ℃ of dry two district's temperature, 59 ℃ of dry three district's temperature, 53 ℃ of dry four district's temperature.
The present invention compared with prior art, has following beneficial effect:
(1) this method increases hot blast leaves moisting operation before wind dispensing operation, is keeping, under the prerequisite of cigarette style, can effectively reducing CO burst size in flue gas.
(2) this method is further optimized the technological parameter of wind dispensing operation and smoked sheet multiple roasting operation, can further reduce CO burst size in flue gas.
(3) this method is for the different technological parameter for tobacco leaf picking of different brackets, and the raw tobacco material aesthetic quality who obtains after parameter adjustment fluctuation can not be too large, otherwise can affect raw material usability, thereby affect acceptance and the degree of recognition of consumer to cigarette product.So this method can not be too large to the adjustment of technological parameter, also need to guarantee raw tobacco material aesthetic quality and reduce CO burst size in flue gas.
