Description

The molten tar detoxification process that falls of tobacco water logging

Technical field

The present invention relates to the molten tar detoxification process that falls of detar technology, particularly tobacco water logging that grows tobacco.

Background technology

Smoking is paid close attention to by the whole world with healthy.Tobacco science and technology tentatively discloses, and the harmful components in the coke tar in cigarette are one of harm health of smokers main matter, reduce cigarette smoke harmful components burst size, improving the security of smoking property of cigarette, is urgent problem in the current cigarette industry, also is the main trend of world's cigarette industry.At present more external big cigarette manufacturers produce all is the low tar blended type cigarette basically, and this cigarette all is to add spices to satisfy psychological needs such as consumer's mouthfeel after reducing tar content basically.And the cigarette that China produces and sells at present all is the cigarette of high tar content fire-cured tobacco type basically.In order to reduce the tar content in China's cigarette, improve the security of smoking property of cigarette, resist the invasion of foreign low tar blended type cigarette, State Tobacco Monopoly Bureau's decision: from July 1st, 2004, China forbade in cigarette market selling tar content at the cigarette more than 15 milligrams/.According to present achievement in research, 99.4% composition is harmless in the cigarette smoke composition of having found, wherein major part is the tobacco flavor matter, have only 0.6% composition harmful, and in this 0.6% oxious component, only have 0.2% to be carcinogenic and possible carcinogenic composition, tar content in cigarette is subjected to pipe tobacco component, cigarette to prop up the influence of factors such as comburant quantity, burning condition and filtration, dilution.Limit owing to technology in the past, can't optionally remove these oxious components, so tobacco business is the technology such as filter tip, punching dilution, expanded cut tobacco stem and reconstituted tobacoo by improving air permeance for cigarette paper, different materials structure aspect process technology, reduce tar content in cigarette.So fall tar,, aroma component is reduced on year-on-year basis, the fragrance of cigarette, jealous and strength are incurred loss, cause that smoke is flat, fragrance is not enough, strength is low excessively, can't satisfy the consumers'physiological requirement though can reduce the part oxious component.In order to reduce tar content in cigarette simultaneously, do not reduce other flavor matter in the cigarette, publication number is that CN1258463, CN1045515, CN1440699 Chinese patent application disclose " a kind of health-care cigarette and manufacture method that reduces coke tar in cigarette and free-radical contents ", " a kind of production technology of low toxicity pipe tobacco " and " a kind of method that reduces oxious component in the tobacco tar " respectively.Wherein publication number CN1258463 disclosed " a kind of health-care cigarette and manufacture method that reduces coke tar in cigarette and free-radical contents " mainly is in the cigarette of explained hereafter routinely, in tobacco fermentation or tobacco leaf throwing in reinforced or filter tip, the filter stick manufacture process, be added with the soy sauce or the soybean tincture of soybean brew, eliminate or reduction coke tar in cigarette and free-radical contents to play, and make the unlikely minimizing of other flavor matters of cigarette, reduce the toxicity of cigarette, reach prevention and reduce the health-care effect that causes lung cancer because of smoking.It saves redrying in the existing tobacco curing silk technology, fermentation, technology such as stifling publication number CN1045515 disclosed " a kind of method that reduces oxious component in the tobacco tar ", and tobacco leaf obstructs through softening, going with giving birth to, adopt after the chopping chemical treatment method of alcohol water blend extraction to remove oxious component in the pipe tobacco effectively.The pipe tobacco tar, the nicotine content that adopt this method to produce are lower than 0.1%, and owing to add harmless excitant and the Chinese medicinal ingredients that can prevent, alleviate respiratory tract, angiocardiopathy in the pipe tobacco, the safety cigarette made from this pipe tobacco not only has the effect of excitor nerve, also has certain medicinal health effect.Publication number CN1440699 disclosed " a kind of method that reduces oxious component in the tobacco tar " is the supercritical CO of elder generation with lower pressure ₂The extraction pipe tobacco obtains pipe tobacco and causes fragrant composition, again with the supercritical CO of elevated pressures ₂The predecessor of extraction pipe tobacco oxious component and harmful components causes pipe tobacco fragrant composition afterwards again with supercritical CO ₂Return and to add pipe tobacco, make tobacco both kept former be necessary cause fragrant composition, reduced oxious component or the illeffects in the tobacco tar again.Though above-mentioned three kinds of methods are playing a role aspect the reduction coke tar in cigarette, it is more complicated in actual mechanical process, and difficulty is bigger.And the two kinds of methods in front also can change the taste of cigarette, make the consumer be difficult to accept.

Summary of the invention

The purpose of this invention is to provide a kind of can keep former be necessary cause fragrant composition, can reduce oxious component or illeffects in the tobacco tar again, and the very simple molten tar detoxification process that falls of tobacco water logging that operates, reduce many weak points that the tar method exists to solve existing tobacco.

The technical solution adopted in the present invention is to increase the molten and baking step of water logging in the baking that has cigarette producing process now between fermentation step, and the molten step of its water logging is that the tobacco leaf after will toasting at normal temperatures and pressures is immersed in the water, and the time is 0.5-3 hour; Draining after the immersion drips puts into drying room and dries to moisture content and be lower than below 10%, and temperature is controlled between 40-50 ℃ during oven dry.

Advantage of the present invention is: in the harmful substance 70% above water solubles such as tar, amine, alkali, can reduce of the harm of these harmful substances to greatest extent in the tobacco, make that the cigarette quality is consummate, mouthfeel is pure and mild human body, tar content is low cause the 3-5 milligram/.The present invention is pure physical method, does not destroy the tobacco natural flavor, does not influence the subsequent production technology of existing tobacco.Also have small investment, effective, easy-operating advantage.
