Description

SH94 is adopted to reduce the baking silk process of cigarette phenol release amount

Technical field

The invention belongs to Harm reduction techniques field, relate to a kind of reduction cigarette phenol release amount process, be specifically related to a kind of cigarette processing method being reduced cigarette phenol release amount by adjustment baking silk technological parameter.

Background technology

" prevent Exposure To Tobacco smog " in " Framework Convention on Tobacco Control ", " control of tobacco composition and disclosure " Liang Ge criterion calls national governments work up more severe " Tobacco Control " laws and regulations, impel tobacco productive corporation while reduction releasing content of coke tar in cigarette, more strictly to control the burst size of main harmful components in cigarette smoke, increase the pressure of industry lowering harm and decreasing coking further, smoking and health are the significant challenge that tobacco business faces, and lowering harm and decreasing coking is related to the survival and development of tobacco business.

For addressing these problems, State Tobacco Monopoly Bureau has printed and distributed " State Tobacco Monopoly Bureau is about the notice advancing lowering harm and decreasing coking work further " (No. (2006) 412, domestic cigarettes section) on June 16th, 2006, proposes new requirement to lowering harm and decreasing coking work.This notice will comprise cigarette smoke 7 kinds of harmful components of phenol as the important indicator characterizing cigarette mainstream flue gas biohazardous.

Phenol is a kind of Volatile phenolics in flue gas, and in tobacco, burst size is very low, mainly produces in cigarette burning process, has strong impulse effect to human body skin and respiratory mucosa.

For promoting the enforcement of the strategic problem of tobacco business lowering harm and decreasing coking further, Harm reduction techniques is advanced 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 advancing lowering harm and decreasing coking work further " (No. (2008) 471, domestic cigarettes section) on August 27th, 2008, clearly propose, by 2010, whole nation cigarette obtains remarkable breakthrough in 7 kinds of harmful components such as selective reduction phenol, is formed 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 the influence research of raw tobacco material, Cigarette processing technique and auxiliary material design to harmful constituents in cigarette flue gas burst size, for lowering harm and decreasing coking application technical research and less harmful product development are provided fundamental basis.

How to reduce the phenol release amount in cigarette mainstream flue gas, reduce smoking to the harm of health, have much research in recent years.But mostly this type of research is that the filter tip by adding additive or prepare special material in cigarette realizes.As Chinese patent the application number announced be 200910307638.9 patent of invention selected a kind of calixarenes additive to make an addition in common conventional filtration mouth, can effectively reduce phenol release amount in cigarette smoke.The application number that Chinese patent is announced be 200810235714.5 patent of invention then propose the mesoporous material of phenol in a kind of adsorbable flue gas, can be used as the adding material of cigarette filter tip.Chinese patent ZL 201010288186.7 discloses a kind of cigarette processing method reducing phenol content,, loosening and gaining moisture loose from microwave and HT+ dry silk three operations and carry out process parameter optimizing respectively, all reach the object reducing phenol release amount in cigarette smoke, thus reach and optimize whole technology for making tobacco threds parameter and reduce the object of phenol release amount, what dry the employing of silk section in patent is that KLD dries silk equipment, does not limit the baking silk equipment of other type.Dry the critical process that silk is production of cigarettes, drying silk technological parameter can produce material impact to cut tobacco physics, sense organ and chemical quality after baking, is the emphasis of technology for making tobacco threds research.

Realizing in process of the present invention, inventor finds to there is following technical problem in prior art:

1, each research institution have ignored the impact of the burst size of specific baking silk technical parameter Pyrogentisinic Acid;

2, differently dry silk equipment to affect difference to the burst size of phenol in cigarette product flue gas huge;

3, due to the particularity of tobacco product, strict requirement is had to baking silk moisture content of outlet, be generally 12% ± 0.5%, under guarantee equipment safety operation and Product Usability prerequisite, combination parameter can only be chosen control in respective adjustable extent, and determine that a parameters combination needs through a large amount of research experiments;

4, pilot production cost is large, and single test only raw material drops into 5-8 ton, cost more than 400,000, and needs to ensure that product can not become waste product in process of the test, adds the difficulty obtaining test data;

The parameter of 5, drying silk technique by adjustment reduces pernicious gas, make to fall harmful effect reach best while, also to ensure that the aesthetic quality of cigarette remains on higher level difficulty large.

Summary of the invention

The object of the invention is, a kind of baking silk technique of specific baking silk equipment is provided, at the Primary Processing of Cigarette processing, adopt SH94 type high speed gas formula stream cut-tobacco drier to reduce cigarette phenol release amount.

The object of the present invention is achieved like this, a kind of baking silk process adopting SH94 to reduce cigarette phenol release amount is provided, uniform Design is carried out to technological parameter, test according to the testing program of design, and detect the phenol release amount of sample main flume, use software DPS 11.0 pairs of test datas to analyze, show that equation is as follows: Y=18.95788915-0.0011204257498X ₁* X ₁+ 0.000005160233534X ₂* X ₂-0.00011791549243X ₁* X ₂, Y is main flume phenol release amount, X ₁for material inlet moisture content, X ₂for steam applied amount;

According to aforesaid equation and verification experimental verification, obtain the technological parameter after optimization as follows:

1), material inlet moisture content: 28.14%;

2), steam applied amount: 323kg/h.

More than drying process application, corresponding Optimizing Process Parameters combination, effectively can reduce phenol release amount in obtained cigarette product flue gas, keeps Sensory Quality of Cigarette to stablize simultaneously.

The invention has the beneficial effects as follows, control technology for making tobacco threds key point---drying process, under the prerequisite keeping Sensory Quality of Cigarette stable, select specific baking silk equipment---high speed gas formula stream cut-tobacco drier carries out parameters combination adjustment, reach the object reducing cigarette phenol release amount, explore Harm reduction techniques and fall burnt new way, there is important theory significance and actual application value.

The present invention carries out screening to the emphasis parameter in drying process and assert and be optimized within the scope of production technology, is ensureing, under the prerequisite that Sensory Quality of Cigarette is stable, effectively to reduce cigarette phenol release amount.
