Embodiment 1

[0010] Example 1: Take 1000 kg of cut stems, pack them under the condition of ensuring the whole cut stems, place the whole in a closed extraction container, inject liquid butane extraction solvent, completely submerge the cut stems, and extract for 30~ 50 minutes, the extraction temperature is 10~60°C; after the extraction, during the process of removing the solvent, the temperature in the extraction container is kept at 10~60°C, after the liquid solvent is drawn from the lower part of the container, the vaporized After the solvent in the shredded stems is completely removed, the shredded stems package is taken out from the container as a whole. The outlet moisture in the cut stem feeding process is 37%, the outlet temperature is 55°C, and the feeding ratio is 2.3wt%; the hot air temperature in the cut stem drying process is 235°C, and the outlet moisture is 13.5%; Silk is added to medium and high-grade cigarettes according to the blending ratio of 5wt%. Compared with the fi...

Embodiment 2

[0011] Example 2: Take 1000 kg of shredded stems, pack them under the condition of ensuring the whole shredded ratio of the cut stems, place the whole in a closed extraction container, inject liquid propane extraction solvent, completely submerge the shredded stems, and extract for 35-45 Minutes, the extraction temperature is 30-50°C; after the extraction is completed, during the process of removing the solvent, the temperature in the extraction container is maintained at 30-50°C, after the liquid solvent is drawn out from the lower part of the container, the vaporized gas is drawn from the upper part of the container Solvent, after the solvent in the shredded stems is completely removed, the shredded stems package is taken out from the container as a whole. The outlet moisture in the cut stem feeding process is 36%, the outlet temperature is 50°C, and the feeding ratio is 2.0wt%; the hot air temperature in the cut stem drying process is 245°C, and the outlet moisture is 13.2%;...

Embodiment 3

[0012] Example 3: Take 1000 kg of cut stems, pack them under the condition of ensuring the whole cut stems, place the whole in a closed extraction container, inject liquid dimethyl ether extraction solvent, completely submerge the cut stems, and extract for 35 -45 minutes, the extraction temperature is 30-50°C; after the extraction is completed, during the process of removing the solvent, the temperature in the extraction container is maintained at 30-50°C, after the liquid solvent is drawn from the lower part of the container, the gas is drawn from the upper part of the container After the solvent in the shredded stems is completely removed, the shredded stems package is taken out from the container as a whole. The outlet moisture in the cut stem feeding process is 36%, the outlet temperature is 50°C, and the feeding ratio is 2.5wt%; the hot air temperature in the cut stem drying process is 245°C, and the outlet moisture is 13.2%; Silk is added to medium and high-grade cigare...

Abstract

The invention provides a method for processing cut stems of middle and top grade cigarettes, and belongs to the technical field of cut stem processing. The method is used for purifying the cut stems, the appearances of the cut stems are maintained good, the tar content in the cut stems is lowered, soluble substances in the cut stems are removed, then through charging backfill, tobacco powder extracts are supplemented, the sensory quality of the cut stems is improved, and the method can be well applied to adding of a formula of top grade cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cut stem processing, and in particular relates to a method for processing cut cut stems for medium and high-grade tobacco. Background technique [0002] Tobacco is a plant of the genus Nicotiana in the family Solanaceae. The shredded stalk is the thick and hard vein of the tobacco leaf, accounting for about 25% to 30% of the leaf weight. It can be added to cigarettes after being shredded. In middle-to-high-end cigarette production enterprises (the tobacco industry divides cigarettes into five categories, which are divided according to the allocation price of cigarettes. Here, medium-to-high-end cigarettes refer to first- and second-class cigarettes), because the cut stems contain unfavorable smoke, taste and Combustible cell wall substances, so its addition is very small and cannot be fully utilized. As a big tobacco producing country, my country produces about 2.4 million tons of tobacco leaves each yea...
