Problems solved by technology

At present, the use of tobacco leaf threshing and redrying processing technology to reduce the CO release in cigarette smoke has not been paid attention to, and there are no related patents and literature reports. method, this method moves the reduction of CO release in cigarette smoke to the stage of threshing and redrying, which is of great value in improving the safety of cigarettes under the premise of ensuring the style of tobacco leaf raw materials, and proposes a method for cigarette harm reduction. new ideas

Embodiment 1

[0025] The tobacco leaf samples produced according to the existing threshing and redrying process parameters were used as blank samples; among them, for the B3F tobacco leaves in a certain place in 2011, a new heating and air-moisturizing process was added, and the tobacco leaf samples produced were optimized samples. The two groups of tobacco leaf samples were loosened, re-moisturized, shredded, and air-dried under the same conditions, and then rolled into cigarette samples. The CO content in the smoke of the two samples was detected in Table 1.

[0026] Table 1: CO content detection results of B3F optimized samples and blank samples

[0027]

[0028] It can be seen from Table 1 that under the new treatment process conditions, the CO content in the flue gas of the tobacco samples produced by this method is 8.91% lower than that of the blank sample, which has an obvious effect of reducing the CO content.

Embodiment 2

[0030] The tobacco leaf sample produced according to the existing threshing and re-baking process parameters is used as a blank sample; in the threshing air classification process, the lower tobacco leaves are X3F in a certain place in 2011, the middle tobacco leaves are C3L in a certain place in 2011, and the upper tobacco leaves are B3F in a certain place in 2011. Adjust the process parameters according to the combination of optimized processing process parameters, and the remaining process process parameters remain unchanged, and the tobacco leaf samples produced are optimized samples; the tobacco leaf samples of each group are loosely rehydrated, shredded, and naturally air-dried under the same conditions, and rolled into cigarette samples. The CO content in the flue gas of the samples is shown in Table 2.

Embodiment 3

[0036] The tobacco leaf sample produced according to the existing threshing and redrying process parameters is used as a blank sample; in the tobacco sheet redrying process, the lower tobacco leaves are X3F in a certain place in 2011, the middle tobacco leaves are C3L in a certain place in 2011, and the upper tobacco leaves are B3F in a certain place in 2011. The process parameters were adjusted according to the combination of optimized processing process parameters, and the process parameters of other processes were kept unchanged, and the tobacco leaf samples produced were optimized samples; the tobacco leaf samples of each group were loosely rehydrated, shredded, and naturally air-cured under the same conditions, and the cigarette samples were rolled. The CO content in the flue gas of the samples is shown in Table 3.

Abstract

The invention discloses a threshing and redrying method for reducing the CO release amount. The threshing and redrying method mainly comprises a threshing air separation working procedure and a tobacco redrying working procedure, wherein a hot air leaf moistening working procedure is added before the threshing air separation working procedure, namely the hot air leaf moistening working procedure is executed after a primary moistening working procedure and a secondary moistening working procedure are executed; the temperature in the hot air leaf moistening is 80-120 DEG C. According to the threshing and redrying method, the hot air leaf moistening working procedure is added before the threshing air separation working procedure, therefore, on the premise of keeping the style of cigarettes, the CO release amount in smoke can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of cigarette raw material processing, and in particular relates to a leaf threshing and redrying method for reducing CO emission. Background technique [0002] CO is one of the important environmental pollutants. It is generally produced by incomplete combustion of C-containing substances. The main mechanism of its toxicity is that the affinity between CO and hemoglobin is 200-300 times higher than that between oxygen and hemoglobin. Therefore, CO is easily Combined with hemoglobin to form carboxyhemoglobin, so that hemoglobin loses its ability and function to carry oxygen, resulting in tissue suffocation. CO has a toxic effect on tissue cells throughout the body, and its effect on the cerebral cortex is particularly serious. [0003] On June 16, 2006, the State Tobacco Monopoly Administration issued the "Notice of the State Tobacco Monopoly Administration on Further Promoting the Work of Harm Reduction and Coke Redu...
