Description
Technical field
The invention belongs to essence spice for cigarette material prepared technology field, be specifically related to a kind of method extracting essence spice for cigarette from cigar mill's processing waste gas.
Background technology
Tobacco essence spices solve cigarette because tar reduce and cause fragrance component to reduce problem on play an important role, the main source of current tobacco spices has: extract gained spices, non-tobacco natural perfume material, synthetic perfume in tobacco.Tobacco is utilized to extract spices cost high, and in cigarette flavor matter up to a hundred in, and some are compositions exclusive in tobacco, non-tobacco natural perfume material and synthetic perfume be difficult to well composite go out these odor types, improving, cigarette is jealous and correct in cigarette foreign gas and still have many defects.
In tobacco processing course, a large amount of waste gas can be produced, consider the problem such as cost and economic benefit, many cigar mills directly discharge the exhaust in air, these waste gas contain a large amount of dust and harmful substance, severe contamination ambient air, affect the healthy of nearby residents.
At present, utilizing cigar mill to process waste gas, to obtain the patent of essence spice for cigarette little, application number is the equipment that patent discloses a kind of tobacco leaf processing waste gas pollution control and treatment and recovery spices of 201320128419.6, part position is flowed through at baking of flue-cured tobacco and cigarette factory discharging waste gas, between air inlet and air outlet, adsorption layer is set, absorbent adopt anhydrous sodium sulfate, sponge, quartz sand, glass fibre, carbon fiber cotton, active carbon, macroreticular resin, silica gel, calcium chloride and acetate fiber one or more; Basket strainer is provided with between air inlet and described adsorption layer.Because the particle in waste gas is adsorbed with a large amount of aroma substances, while utilizing basket strainer filtration of particulate matters, these materials are also wasted; Absorbent used is while absorption flavor matter, also much impurity and pernicious gas is absorbed, and when carrying out molecular clock to the absorbent reclaimed, part harmful substance is similar to the essence and flavoring agent moieties free path of required extraction, cause in the fragrance material of gained containing much impurity; And wherein contained many aroma components are extremely micro-, are difficult to effectively distill acquisition; In addition, the flavor matter in waste gas has tens kinds, causes molecular clock process extremely loaded down with trivial details.
Summary of the invention
The object of the invention is to make up prior art, a kind of method extracting essence spice for cigarette from cigar mill's processing waste gas is provided, the method can make harmful substance be separated thoroughly, and obtained essence spice for cigarette is impure few, crystal grain Heat stability is good, not easily moisture absorption sex change, storage life is long, easy to use, and fragrance is soft pure, have unique naturally cigarette fragrance breath, excitant is little.
From cigar mill's processing waste gas, extract a method for essence spice for cigarette, comprise the following steps:
1. cigar mill's waste gas is passed through acf layer, adsorbent layer successively, described adsorbent layer is made up of cigarette acetate silk and potassium chloride crystal grain;
2. shower washing is carried out to acf layer, cleaning solution is the Tea Polyphenols aqueous solution of 0.8 ~ 1.2% mass concentration, the cleaning solution of gained after collection shower, layering is shaken after fully stirring, be divided into three layers, upper strata is the broken end of tobacco leaf, middle level is the aqueous solution, lower floor is water-fast organic solution, and precipitation is contained in middle level and lower floor;
3. isolate the broken end of bright tips, essence spice for cigarette is prepared in technical finesse routinely, and remaining liq enters centrifuge;
4. by step 1. in be passed in the Tea Polyphenols aqueous solution of 0.8 ~ 1.2% mass concentration by the gas after adsorbent layer, after fully stirring, liquid also enter step 3. described in centrifuge;
5., after adopting centrifuge to carry out centrifugation, discard the aqueous solution and precipitation, isolate organic solution;
6. organic solution is joined in the saturated sugar syrup liquid containing 3.5 ~ 4% mass concentration glycerine, fully after mixing, dry obtained essence spice for cigarette crystal grain.
The mass ratio of described cigarette acetate silk and potassium chloride crystal grain is 8.5 ~ 9:1.
The volume ratio of described organic solution and saturated sugar syrup liquid is 20 ~ 22:1.
The waste gas of cigar mill is when by acf layer, effectively can isolate the broken end of tobacco leaf in waste gas and most of particle, these particles contain the harmful substances such as a large amount of benzene-like compounds and nicotine, particle is adsorbed with many tobacco flavor materials simultaneously, needs to be separated further these filtrate.Rinsed by the Tea Polyphenols aqueous solution of 0.8 ~ 1.2% mass concentration, these benzene-like compounds and nicotine can be gone out by precipitation and separation, and decompose the harmful substance such as low grade aldehyde, hydrogen cyanide, BaP, polycyclic arene compound removed wherein, the broken end of isolated tobacco leaf, just technical finesse can prepare essence spice for cigarette routinely, and by the gas of acf layer, adopt a small amount of cigarette acetate silk and potassium chloride crystal grain just can the pernicious gas such as carbon monoxide effectively in filtering exhaust, remove free radical contained in gas, avoid polluting spices and air, extend the shelf-life of spices, simultaneously very little to the delay effect of fragrance matter, fragrance matter in waste gas is further purified, and these waste gas are still containing part benzene-like compounds, nicotine, low grade aldehyde, hydrogen cyanide, BaP, the harmful substances such as polycyclic arene compound, need to be passed in the Tea Polyphenols aqueous solution of 0.8 ~ 1.2% mass concentration, it is further separated, the twice Tea Polyphenols aqueous solution passes through centrifuge, the organic solution that centrifugation goes out, join in the saturated sugar syrup liquid containing 3.5 ~ 4% mass concentration glycerine, abundant mixing, drying makes essence and flavoring agent transform crystallization, these organic substances can be combined with crystal grain well, Heat stability is good, not easily moisture absorption sex change, storage life is long, containing the aroma component needed for tens kinds of cigarettes, comprise large molecule aldehydes, ester class, carboxylic acids and many trace organic components etc., and these prior aries are difficult to analyze the trace organic component measured, that non-tobacco or artificial allotment when preparing essence spice for cigarette are difficult to obtain, effectively can make up the fragrance ingredient reduced because tar reduces, improve the jealous of cigarette.
