Description
The invention relates to manufacture method of a kind of pipe tobacco and products thereof, more particularly about manufacture method of a kind of dark coffee or black roasted pipe tobacco and products thereof.
Existing cigarette is tobacco product, and the burning by tobacco leaf or pipe tobacco during use produces smog, and the smoker just sucks this smog.Contain multiple harmful substances such as BaP, nitrosamine, nicotine, carbon monoxide, arsenic, polonium, cadmium in the smoke from cigarette.These harmful substances can be brought out cancer, can promote artery sclerosis and produce coronary heart disease, also cause rhinitis, pharyngitis, laryngitis, bronchitis, pulmonary emphysema and pulmonary heart disease.Many physicians have carried out seven extensive paired observation at number the crowd more than 1,000,000 in Britain, the U.S. and three countries of Canada, a large amount of survey data show, smoking is the main cause of male lung cancer, smoker's lung cancer mortality is high more than the non-smoker, and ratio non-smoking high 18.4 times of lung cancer death suffered from smoking every day more than 20.Can think, suffer from lung cancer and dead major part is because smoking.In recent years, state's lung cancer mortalities such as Britain, the U.S., France, West Germany all account for the first place of the male cancer death rate, and Beijing's lung cancer death then is the first place of various cancer mortalities, and Shanghai City is second.The reason of lung cancer is not only in smoking, also increases the danger of suffering from other position cancer, as laryngocarcinoma, carcinoma of mouth, carcinoma of urinary bladder, the cancer of the esophagus etc.Smoke from cigarette is not only poisoned the smoker, and also contaminated air causes public hazards.Smoking has become a urgent public health problem.Although some manufacturer has taked some attenuation measures at tobacco now,, the generation of carcinogens such as BaP just must be arranged as long as the burning of tobacco leaf or pipe tobacco is in use arranged.Because BaP might not exist in tobacco leaf, BaP but produces in the cigarette combustion process.Not only cigarette combustion produces BaP, and almost all organic burnings all can produce BaP.BaP is strong carcinogenic substance, and the smog that the Linear Leaf Speedwell cigarette is produced contains BaP 25 nanograms approximately.No matter which type of attenuation measure manufacturer taked at tobacco in other words, but as long as the burning of tobacco leaf or pipe tobacco is in use arranged, the generation of carcinogens such as BaP just must be arranged, and this produces the root problem of poisoning is insurmountable.Although countries in the world are advised that people do not want smoking, and taked some measures to limit smoking all at the propaganda harm of smoking in recent years, the smoking phenomenon of countries in the world still exists in a large number.
In the prior art, the fermentation of tobacco leaf can be divided into spontaneous fermentation and artificial fermentation.Spontaneous fermentation is that the tobacco leaf after the modulation is placed in the warehouse through packing, makes it under natural climate condition, refines along with the influence of seasonal temperature variation.This fermentation time is long, and it is big to take storage area, rainy season tobacco leaf go mouldy easily.The artificial fermentation puts into tobacco bale in the fermenting cellar that can control indoor temperature and relative humidity that a spy builds to ferment.The artificial fermentation compares with spontaneous fermentation, and the former has shortened fermentation time.But the artificial fermentation is owing to need higher temperature and humidity, thereby will consume a large amount of energy.Sometimes because tobacco bale heats up slowly, humidity is gone mouldy greatly, causes loss economically again.
One of purpose of the present invention provides a kind of dark coffee or black roasted pipe tobacco.
Two of purpose of the present invention provides a kind of manufacture method of dark coffee or black roasted pipe tobacco.
These and other objects of the present invention will further embody and illustrate by following detailed and explanation.
In the present invention, the manufacture method of pipe tobacco comprises the steps:
At first pipe tobacco is put into installation for fermenting, shutoff device injects humidity and is 16%～25% steam then in proportion, and vapor volume is that the water content to tobacco leaf is each hundred kilograms of moisture 2～25Kg of tobacco leaf, and installation for fermenting comprises fermentation machine, fermenting cellar, steam baking machine; Heat to 60 ℃～80 ℃, turn round after 2 to 4 hours, the running speed when then fermenting as employing fermentation machine is 2～20 rev/mins; Again with temperature increase to 110 ℃ to 130 ℃ of distillation oxidations 2 to 6 hours, under high temperature, super-humid conditions, distill, ferment, evaporate a large amount of steam, assorted gas and other harmful substance, accelerate pipe tobacco fermentation and the speed of refining simultaneously, close heating source then, device for opening, slowly venting to below 100 ℃, is dried or fries dried.By repeatedly discharging steam, assorted gas and nuisance, can reduce the tar composition in the pipe tobacco, increase the water-soluble sugar amount; By said process, the variation of fermentation at a high speed takes place in pipe tobacco, and reaching dark brown to black with the pipe tobacco color is standard, pipe tobacco is finally reached reduce the purpose of harmful material and sweet-smelling, GOOD TASTE.
The color and luster of pipe tobacco of the present invention is dark coffee or black roasted, and blackness value is 1～3, and tar content is lower than 13 milligrams/, content of nitrosamines be lower than 1 microgram/, BaP content is lower than 0.22 milligram/, and nicotine content is lower than 0.8 milligram/, and amino acid content is two times of conventional nicotinic acid content.
In pipe tobacco, has volatile cancer promoter-polyphenol, be insoluble to organic solvents such as benzinum, be slightly soluble in cold water, be soluble in boiling water, this characteristic of base places 80 ℃～100 ℃ high temperature distillation to ferment cigarette shreds, contained nicotine just aggravates volatilization in the tobacco leaf cell, takes out of external along with the evaporation of free moisture content in the pipe tobacco.Higher fermentation temperature, help the enzymatic reaction of tobacco leaf cell and the carrying out of oxidation reaction, its result causes impairing the hydrophilic substance of cigarette quality such as nitrogen, cyanogen, chlorine, the sulphur equal size reduces, and harmful tar composition reduces, increase the water-soluble sugar amount, thereby reach the effect of attenuation flavouring.
Pipe tobacco color and luster after method processing of the present invention is dark coffee or black roasted, can not only reach because of having removed harmful substances such as nicotine and obtain more reliable security, aspect other quality, pipe tobacco of the same race after the conventional fermentation is compared, the pure homogeneous of color and luster, jealous pure and mild, have more fragrance, and shortened fermentation period.
