Abstract
The invention discloses a tobacco leaf processing method for selectively reducing the cigarette smoke gas NH3 releasing quantity. At first, a leaf moistening cylinder is preheated to enable circulating hot wind to reach the 80 DEG C-120 DEG C temperature, and then materials are began to feed. Secondarily, a hot steam valve and a moist steam valve are adjusted according to parts of processed tobacco leaves to respectively control the temperature and the water content of a tobacco moistening leaf. At last, steam is fully adopted, the temperature accords with technological requirements of <YC / T146-2010 tobacco leaf breaking re-roasting process specification>, and processing is carried out. The tobacco leaf processing method for selectively reducing the cigarette smoke gas NH3 releasing quantity is obvious in effect, reduces the amplitude by more than 30%, is good in repeatability and suitable for leaf breaking re-roasting actual production, expands the tobacco leaf processing technology for reducing harmful ingredients of cigarette smoke gas, and has good practical significance and reference functions for harmful ingredient-reduction tar-reduction work of the industry.
Description
Technical field
The invention belongs to the beating and double roasting technical field, specifically relate to a kind of tobacco leaf processing method that can selectivity reducing cigarette fume NH3 burst size.
Background technology
Ammonia (NH3) not only influences the jealous of cigarette, also can influence vision and the respiratory system of human body, long-term suction meeting causes serious harm to human body, therefore ammonia is a kind of main harmful components of generally acknowledging in the cigarette mainstream flue gas, spells out NH3 as one of important indicator that characterizes cigarette mainstream flue gas harmfulness in 2008 " State Tobacco Monopoly Bureau is about the notice of further propelling lowering harm and decreasing coking work " (No. [2008] 471, domestic cigarettes section).
NH3 is mainly derived from the nitrogen-containing compound in tobacco and other auxiliary material.As protein, amino acid, nitrate, ammonium salt, alkaloid and nitrogen-containing heterocycle compound, in the cigarette burning process, all can produce NH3 to some extent.
In recent years, people have carried out big quantity research to cigarette smoke NH3 burst size and mechanism thereof, its objective is the technical method of seeking to reduce cigarette smoke NH3 burst size, and have obtained some achievements in research.Can 8.8～20.7% as disclosed technological invention " a kind of soybean fibrillarin composite tip stick and preparation method thereof (publication number: CN102178351A) ".But up to now, Shang Weiyou reduces the method report of NH3 content in the cigarette smoke by the improvement of tobacco leaf processing method.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of improved tobacco leaf processing method is provided, by preheating leaves moisting bucket, adopts pressure decatizing vapour leaves moisting and low temperature roasting operation slowly, and optimize this 3 procedure combination of process parameters, finally reach the purpose of selectivity reducing cigarette fume NH3 burst size.
Purpose of the present invention is achieved by the following technical programs.
Except as otherwise noted, percentage of the present invention is mass percent.
A kind of tobacco leaf processing method of selectivity reducing cigarette fume NH3 burst size may further comprise the steps:
(1) leaves moisting ladle preheating: before feeding intake, setting the steam pressure value is 0.8～1MPa, opens heat exchanger, and preheating leaves moisting tube begins to feed intake after making circulating air reach 80 ℃～120 ℃;
(2) pressure decatizing vapour leaves moisting: according to processing tobacco leaf position, regulate heat, moist steam valve, make temperature and the moisture content of a profit tobacco leaf reach following requirement respectively: 1. upper tobacco leaf: temperature is 55 ℃～65 ℃, and moisture is 18%～21%; 2. tobacco leaf in the middle part of: 50 ℃～56 ℃, moisture is 18%～20%; 3. lower tobacco leaf: 50 ℃～58 ℃, moisture is 18%～20%; When two profit moisture and temperature reach the technological requirement of regulation " YC/T146-2010 tobacco threshing and redrying technological specification " in, open front/rear steam valve, adjust two profit moisture and temperature, circulating air is controlled 80～100 ℃ of scopes;
(3) redrying moisture regain: adopt pressure decatizing vapour, temperature meets " YC/T146-2010 tobacco threshing and redrying technological specification " technological requirement.
With respect to prior art, the present invention has the following advantages:
1, in beating and double roasting, adopt pressure decatizing vapour leaves moisting and low temperature to bake the burst size that coordination technique selectively reduces NH3 in the raw tobacco material flue gas slowly;
2, the effect of the burst size of NH3 is obvious in this choice of technology reduction raw tobacco material flue gas, and the reduction amplitude is more than 30%;
3, the feasible practicality of method.In industry tobacco threshing and redrying operation, realize this technology easily.
4, in tobacco leaf processing, can selectively effectively reduce the burst size of NH3 in the raw tobacco material flue gas, reduce the burst size of NH3 the cigarette product flue gas from raw tobacco material at all.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment, but embodiment is not limited to the technical solution.Anyly be familiar with those skilled in the art in the technical scope that the present invention discloses, be equal to according to the solution of the present invention and inventive concept thereof and replace or change, all should be encompassed in protection scope of the present invention.
