Abstract

The invention relates to a cigarettes processing method of reducing NNN content, and the specific process parameters of the main process steps are as follows: 1) the microwave loosening process step: the microwave power is 120KW, and the processing time is 248s; 2) the loosening and conditioning process step: the steam pressure of a water vapor nozzle is 0.3Mpa, the temperature of hot air is 48 DEG C, and the rotational speed of a cylinder body is 9r/min; and 3) the HT and cut tobacco drying process step: the HT working steam pressure is 0.6Mpa, the temperature of the hot air is 96 DEG C, the opening degree of a moist air removing door is 54%, the opening degree of a hot air door is 61%, and the rotational speed of the cylinder body is 10r/min; and the HT is the cut tobacco temperature-increasing and moisture-increasing process step which is carried out by adopting a tunnel type cut tobacco temperature-increasing and moisture-increasing machine. The processing method can effectively reduce the release amount of low NNN in smoke gas of the prepared cigarette products through optimal combination of process parameters of the existing process steps.

Description

A kind of cigarette technological method for processing that reduces NNN content

Technical field

The present invention relates to the method for tobacco cutting, be specifically related to a kind of cigarette technological method for processing of the NNN of reduction burst size.

Background technology

Smoking is harmful to your health has obtained the consistent of various circles of society and has generally acknowledged, under the promotion of the World Health Organization, many national government and various back suction cigarette group, the anti-smoking campaign in the whole world grows to even greater heights, and the social pressures that tobacco business receives are increasing.Stipulate in Chinese government's signed " Framework Convention on Tobacco Control " that the Chinese government will 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.For improving the quality and the security of China's cigarette product; State Tobacco Monopoly Bureau clearly proposes to 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.

TSNAs is distinctive one type of nitrosamine in tobacco and the tobacco product; The NNN of one of them is paid attention to by the public; Be not only because its content is higher, especially because the concrete strong carcinogenic activity of NNN has been identified relevant with the generation of position tumours such as lung, oral cavity, esophagus, pancreas, liver.At present; Reducing this type of approach that is harmful to has in the cigarette filter production process and to add tobacco leaf that this type of material is had the material of adsorption capacity or selects low TSNAs for use as the cigarette raw material, and does not appear in the newspapers from the burst size that cigarette processing technology angle sets about reducing TSNAs.

Summary of the invention

The cigarette technological method for processing that the purpose of this invention is to provide a kind of NNN of reduction content; Set about through the loose operation of microwave from the cigarette processing technology, loosening and gaining moisture operation, these three procedure technology parameters of HT+ drying process, explore a kind of cigarette technological method for processing that reduces the NNN burst size.

The objective of the invention is to realize like this: a kind of cigarette technological method for processing of the NNN of reduction 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 120KW, process time 248s;

2), loosening and gaining moisture operation: steam nozzle steam pressure 0.3Mpa, 48 ℃ of hot blast temperatures, drum speed 9r/min;

3), HT and drying process: HT working steam pressure 0.6Mpa, 96 ℃ of hot blast temperatures, humidity discharging throttle opening 54%, hot blast throttle opening 61%, drum speed 10r/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 the burst size of NNN 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.

The tobacco flow process chart that Fig. 1 the present invention relates to.

The specific embodiment

Below in conjunction with embodiment the present invention is done further elaboration.

Embodiment 1:

In the loose operation of technology for making tobacco threds microwave, be the basic process parameter with the loose procedure technology parameter of the microwave of focus shaft brand cigarette, carry out tobacco cutting with this basic process parameter, the tobacco sample of generation is a blank sample; The tobacco sample of producing according to the parameters optimization of step 1 is the optimization sample, and the result is following:
