Abstract

The invention provides a processing technological method of a cigarette for reducing a heavy metal content V. The specific technological parameters of the main processes of the method are as follows: (1) microwave loosening process performed under the condition that the microwave power is 180 KW and the processing time is 240 s; (2) loosening reversion process performed under the condition that the steam pressure of a water vapor nozzle is 0.3 MPa, the hot air temperature is 55 DEG C, and the rotation speed of a cylinder is 13 r/min; and (3) HT and cut tobacco baking process performed under the condition that the HT work steam pressure is 0.6 MPa, the hot air temperature is 105 DEG C, the openness of a humidity discharging air door is 79%, the openness of a hot air door is 31%, and the rotation speed of the cylinder is 9 r/min, wherein the HT is a cut tobacco warming and humidifying process by adopting a tunnel type cut tobacco warming and humidifying machine. In the invention, the content of the heavy metal V in the smoke of the produced cigarette product is effectively reduced through the optimized combination of the technological parameters of the traditional processes.

Description

A kind of cigarette technological method for processing that reduces content of beary metal V

Technical field

The present invention relates to the method for tobacco cutting, be specifically related to a kind of cigarette technological method for processing that reduces content of beary metal V.

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.

In recent years, along with the continuous progress of analytical technology, harmful element V is detected in tobacco and tobacco product.V is a moderately toxic heavy metal species, can when accumulation reaches finite concentration in human body, will be influenced stomach, nervous system and heart by systemic absorption.Different with other food, the heavy metal V in the cigarette gets into human body by the flue gas that sucks burning, is detrimental to health.At present, mainly concentrate on the analytical method for the research of V in the tobacco, the V that how to reduce in the tobacco does not appear in the newspapers.

Summary of the invention

The purpose of this invention is to provide a kind of cigarette technological method for processing that reduces content of beary metal V, be intended to set about, explore the cigarette technological method for processing that reduces content of beary metal V from the cigarette working process parameter.

The objective of the invention is to realize like this: a kind of cigarette technological method for processing that reduces content of beary metal V, 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 180KW, process time 240s;

2), loosening and gaining moisture operation: steam nozzle steam pressure 0.3Mpa, 55 ℃ of hot blast temperatures, drum speed 13r/min;

3), HT and drying process: HT working steam pressure 0.6Mpa, 105 ℃ of hot blast temperatures, humidity discharging throttle opening 79%, hot blast throttle opening 31%, drum speed 9r/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 content of metal V 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.

Description of drawings

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:

The content of the loose operation tobacco sample of table 1 microwave V

The sample title	Microwave power (KW)	Process time (second)	V(μg/g)
