Example Embodiment

[0010] Example 1: Take 1000 kg of shreds, pack them under the condition of ensuring the rate of straightness of shreds, put the whole in a closed extraction container, inject liquid butane extraction solvent, immerse the shreds completely, and extract 30~ After 50 minutes, the extraction temperature is 10~60℃; after the extraction, the temperature in the extraction vessel is maintained at 10~60℃ during the process of removing the solvent. After the liquid solvent is drawn out from the lower part of the vessel, it is vaporized from the upper part of the vessel. After the solvent in the shreds is completely removed, take out the whole shreds package from the container. The outlet moisture of the stalk feeding process is 37%, the outlet temperature is 55°C, and the feeding ratio is 2.3wt%; the hot air temperature of the stalk drying process is 235°C, and the outlet moisture is 13.5%; the stalk's flavoring ratio is 0.5wt%. The silk is added to the medium and high-end cigarettes acc...

Example Embodiment

[0011] Example 2: Take 1000 kg of shreds, pack them under the condition of guaranteeing the silking rate of shreds, put the whole in a closed extraction container, inject liquid propane extraction solvent, immerse the shreds completely, and extract 35-45 Minutes, the extraction temperature is 30-50°C; after the extraction, the temperature in the extraction vessel is maintained at 30-50°C during the removal of the solvent. After the liquid solvent is drawn from the lower part of the vessel, the vaporized solvent is drawn from the upper part of the vessel. After the solvent is completely removed from the shreds, take out the whole shreds package from the container. The outlet moisture of the stalk feeding process is 36%, the outlet temperature is 50°C, and the feeding ratio is 2.0wt%; the hot air temperature of the stalk drying process is 245°C, and the outlet moisture is 13.2%; the stalks adding fragrance ratio is 0.5wt%. The silk is added to the middle- and high-end cigarettes ...

Example Embodiment

[0012] Example 3: Take 1000 kg of shreds, pack them under the condition of ensuring the rate of straightness of shreds, put the whole in a closed extraction container, inject the liquid dimethyl ether extraction solvent, immerse the shreds completely, and extract 35 -45 minutes, the extraction temperature is 30-50°C; after the extraction, the temperature in the extraction vessel is maintained at 30-50°C during the solvent removal process. After the liquid solvent is drawn from the lower part of the vessel, the gas is drawn from the upper part of the vessel After the solvent is completely removed from the stalks, the stalk package is taken out from the container as a whole. The outlet moisture of the stalk feeding process is 36%, the outlet temperature is 50°C, and the feeding ratio is 2.5wt%; the hot air temperature of the stalk drying process is 245°C, and the outlet moisture is 13.2%; the aroma of the stems is 0.5wt%. The silk is added to the middle and high-end cigarettes ac...

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...
