Description
Technical field
The present invention relates to reduce the cigarette technological method for processing of crotonaldehyde content, be specifically related to a kind of cigarette throwing emphasis procedure technology method that reduces crotonaldehyde content.
Background technology
" prevent to contact tobacco smoke " in " Framework Convention on Tobacco Control ", " control of tobacco composition and disclosure " two criterions require national governments to work up more severe " Tobacco Control " laws and regulations; Impel tobacco productive corporation when reducing releasing content of coke tar in cigarette; More want the burst size of main harmful components in the strict control cigarette smoke; Further strengthened the pressure of industry lowering harm and decreasing coking; Smoking is the main challenge that tobacco business faces with health, 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 of further propelling lowering harm and decreasing coking work " (No. (2006) 412, domestic cigarettes section) on June 16th, 2006, and work has proposed new requirement to lowering harm and decreasing coking.This notice will comprise that 7 kinds of harmful components of cigarette smoke of crotonaldehyde are as the important indicator that characterizes cigarette mainstream flue gas biohazard property.
Volatile carbonyl compound is one type of important harmful substance in the cigarette smoke, in the flue gas gas phase, has found 20 kinds of aldehyde and 6 kinds of ketone at present at least.Wherein crotonaldehyde content is higher, and eye conjunctiva, nose and upper respiratory tract mucosa and skin are had excitant, and long-term contact can cause and cause rhinitis chronic, dermatitis, respiratory disease and nervous system function obstacle.
For further promoting the enforcement of the strategic problem of tobacco business lowering harm and decreasing coking; Advance carrying out in a deep going way of cigarette lowering harm and decreasing coking 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, national cigarette reduces in selectivity was obtaining remarkable breakthrough aspect 7 kinds of harmful components such as crotonaldehyde, formed a collection ofly to have the core technology of independent intellectual property right and in industry focus shaft cigarette brand, be applied.And think and should strengthen raw tobacco material, cigarette processing technology and the auxiliary material design influence research to harmful components burst size in the cigarette smoke, for lowering harm and decreasing coking application technical research and low harm product development are provided fundamental basis.
How to reduce the crotonaldehyde content in the cigarette mainstream flue gas, reduce the harm of smoking, many researchs are arranged in recent years health.This type of research mainly is to reduce the crotonaldehyde content in the cigarette smoke through the filter tip that application specific is developed.The patent No. of announcing like Chinese patent is the additive that the patent of invention of ZL200710192691.X provides aldehyde material in a kind of selectivity reducing cigarette fume; Be to be carrier with the silochrom; Introduce functional groups through modification; Thereby the compound layer that has amino, urea groups or amide groups in carrier surface and duct surface coverage last layer and aldehyde material reaction; Carrier after the modification is applied to cigarette filter, can optionally reduces the content of aldehyde materials such as formaldehyde in the cigarette smoke, acetaldehyde, propionic aldehyde, methacrylaldehyde, crotonaldehyde.The application number that Chinese patent is announced is that the described a kind of paper filter stick use paper that reduces aldehyde material in the cigarette smoke of the patent of invention of ZL200810107510.3 is one or more paper of processing that contain in wood pulp cellulose or the ramie pulp fiber; Described paper is through coating processes; Through the high-hydroscopicity of paper, apply and contain amino compound solution, cut after the drying; Embossing is processed paper filter stick through the mouth rod forming machine.Papery filter tip of the present invention can reduce crotons aldehyde in the cigarette smoke effectively.And cigarette technology for making tobacco threds parameter is not also appeared in the newspapers to the influence of crotons aldehyde in the cigarette mainstream flue gas so far.
Summary of the invention
The purpose of this invention is to provide a kind of cigarette technological method for processing that reduces crotonaldehyde content, through combination of process parameters, to reduce crotonaldehyde burst size in the cigarette smoke at cigarette silk producing procedures optimizing application.
The objective of the invention is to realize like this: a kind of cigarette technological method for processing that reduces crotonaldehyde content, main by the loose operation of the microwave that carries out in order, loosening and gaining moisture operation and HT+ drying process are formed, and the concrete technological parameter of operation is following:
1), the loose operation of microwave: microwave power 136KW, process time 320s;
2), loosening and gaining moisture operation: vapour, (operating) water nozzle steam pressure 0.3MPa, 48 ℃ of return air temperatures, drum speed 9r/min;
3), HT and drying process: HT working steam pressure 0.60MPa, 85 ℃ of hot blast temperatures, humidity discharging throttle opening 53%, hot blast throttle opening 70%, drum speed 9r/min;
The leaf silk warming and humidifying operation of HT for adopting tunnel type leaf silk warming and humidifying machine to carry out.
Optimize combination of process parameters accordingly in above each processes employ, can effectively reduce crotons aldehyde in the obtained cigarette product flue gas.
The invention has the beneficial effects as follows from cigarette processing technology angle and explored cigarette lowering harm and decreasing coking new way, have important significance for theories and actual application value.
