Embodiment

[0014] Embodiment: The new process steps of the present invention are: rehydrating the tobacco stems, storing the stems, increasing the temperature of the tobacco stems, cutting the cut stems, washing the cut stems, dehydrating, backfilling the cut stems with liquid material, drying the cut stems, drying and puffing the cut stems.

[0015] The key points of the new process of reconstituted shredded stems are:

[0016] The shredded stems (thickness 0.12-0.18mm) enter a continuous extraction device. Enter the extraction with a solvent. The ratio of the material to the solvent is 1:20, the solvent is (edible ethanol, glycerin, propylene glycol, petroleum ether, purified water), and the time is 20 to 60 minutes. The solvent temperature is 20-50°C. Extraction method: downstream. The extracted shredded stems are separated into solid and liquid through extrusion and centrifugation. The separation liquid is treated separately, and the shredded stem enters the next process after sep...

Abstract

The patent of the invention relates to the field of reproduced tobacco product manufacturing technology, in particular to a method for manufacturing tobacco cut stems. The method comprises the following steps: the cut stems after being cut enter a continuous extraction device, and are extracted with solvent, wherein the proportion of materials to the solvent is 1:20, the time lasts 20-60 minutes, and the temperature of the solvent is 20-50 DEG C; an extraction mode is as follows: forward flow is conducted, the extracted cut stems are subjected to solid-liquid separation through extrusion and centrifugation, and then subjected to feed liquid backfill, wherein the feed liquid concentration is 30%-40%, the feed liquid temperature is 20-40 DEG C, the application proportion is 40-120%; and the backfill mode is as follows: the spraying is conducted. After being subjected to liquid feed backfill, the cut stems have higher water content which is about 65%, so that the water content of the cut stems after the water pretreatment is reduced to about 35% from 65%, and then the cut stems are subjected to tower type expansion or air flow drying. The cut stems prepared by the process has better color and luster and good filling value, the cigarette quality is improved obviously, the harmful contents such as tar and carbon monoxide in the cigarette are reduced greatly, the utilization ratio of stem raw materials is improved greatly, and the cost for a single box is lowered greatly.

Description

[technical field] [0001] The patent of the present invention relates to the technical field of manufacturing remanufactured tobacco products, specifically a method for manufacturing shredded tobacco stems. [Background technique] [0002] 1. Tobacco stems are an important part of tobacco leaves, and the content of tobacco stems in tobacco leaves is about 25-30%. At present, the blending amount of tobacco stems in the leaf group is about 15% in the tobacco industry. Most high-end cigarette products have little or no blending. This is mainly because the tobacco industry has not yet found an effective processing method for substantially improving the quality of cut stems. The traditional cut stem treatment process focuses on the filling performance and combustion performance of the cut stem. [0003] 2. Because the grade, place of origin, and variety of tobacco leaf raw materials affect its internal chemical composition, the following is a list of the conventional chemical an...
