Problems solved by technology

This invention uses microwave means to reduce the content of carbon monoxide in the mainstream smoke of cigarettes by changing the process of making shredded cigarettes. Although it has a certain effect on reducing the content of carbon monoxide in the smoke, microwave equipment is expensive and the processing cost is high. The combination of tobacco processing technology is difficult to promote and apply in industrial production
Therefore, none of these treatments has ideal selectivity, and it is necessary to develop a method for reducing carbon monoxide in cigarette smoke

Embodiment 1

[0026] Randomly take 150kg of first-cured tobacco leaves, pack each 50kg into a box, a total of 3 boxes, and pack them in a corrugated box with a length x width x height of 70cm x 60cm x 50cm. The stacking thickness of the tobacco leaves in the carton is 26-72cm. 0.20~0.34g / cm 3 ;Place the packaged tobacco leaves on the conveying device with a conveying speed of 0.02-0.3m / s; the tobacco leaves placed on the conveying device are irradiated with electron beam / X-rays generated by an electron accelerator, and the energy of the electron accelerator is 5-10MeV , the beam current is 0.3-20mA, the beam power is 10-20kW, the maximum scanning width is 100cm, the scanning frequency is 5-15Hz, the irradiation dose is 1kGy, the way of secondary irradiation is adopted, and the tobacco leaves are transported through the conveying device twice. The scanning window of the electron accelerator is irradiated, and half of the radiation dose is received at a time. After the first irradiation, the ...

Embodiment 2

[0030] Randomly take 3 boxes of re-cured tobacco leaves packed in standard boxes, the carton length x width x height is 113.6cm x 72cm x 72.5cm, and each box weighs 200kg. Use 5kGy dose of X-rays for irradiation treatment. After irradiation, the tobacco leaves are rolled by a cigarette rolling machine, and 40 cigarettes that meet the measurement requirements are randomly selected. According to the standard conditions stipulated in GB / T 19609-2004, a smoking machine is used to simulate the state of human smoking. , using a gas absorption bottle to collect carbon monoxide in the smoke, using non-scattering infrared method to measure the content of carbon monoxide, using the corresponding unirradiated cigarette sample as a control, and evaluating smoking. The results are shown in Table 2.

Embodiment 3

[0034]Take 3 boxes of finished cigarettes at random, the carton length x width x height is 47.5cm x 26cm x 59.5cm, each box weighs 15kg, and the quantity is 50. The electron beam with a dose of 10kGy is used for irradiation treatment. After irradiation, 40 cigarettes that meet the measurement requirements are randomly selected. According to the standard conditions stipulated in GB / T 19609-2004, a smoking machine is used to simulate the state of human smoking, and a gas absorption bottle is used to collect cigarettes. The carbon monoxide in the air was measured by non-scattering infrared method, and the corresponding unirradiated cigarette samples were used as the control, and the smoking evaluation was carried out. The results are shown in Table 3.

Abstract

The invention discloses a method for lowering carbon monoxide content in main smoke of cigarette. The method comprises the steps of: packaging tobacco leaves / cigarette finished product with cartons, wherein the stacking thickness is 26-72cm and the stacking density is 0.20-0.34g / cm<3>; and placing the cigarette cartons on a conveying device with conveying speed of 0.02-0.3m / s and irradiating withelectron beam / X ray generated by an electron accelerator, wherein the energy of the electron accelerator is 5-10MeV, the beam current is 0.3-20mA, the beam power is 10-20kW, the maximum scanning width is 100cm, the scanning frequency is 5-15Hz, the irradiation dose is 1-10kGy, the working temperature is set at 5-35 DEG C, the cigarette cartons pass through a scanning window of the electron accelerator twice to undergo irradiation, the distance between the center of the cigarette carton and the scanning window of the electron accelerator is 40-60cm during irradiation, and the ambient humidity is limited to be not more than 60% during working.

Description

technical field [0001] The invention belongs to the application field of irradiation technology, and also belongs to the technical field of tobacco tar reduction and harm reduction, and relates to the application of electron accelerator irradiation technology in reducing tobacco harm, in particular to an electron accelerator irradiation technology capable of reducing the carbon monoxide content in mainstream smoke of cigarettes. According to processing technology. Background technique [0002] Tobacco is one of the important economic crops in our country and occupies an important position in the national economy. At present, there are 1.1 billion smokers in the world, and there are more than 300 million in China. Smoking has become a social group behavior. As early as the 1930s, it was suggested that smoking is harmful to health. In particular, the Royal Society of Medicine in 1950 and the US Medical Administration in 1964 officially published a report on the relationship b...
