Method for manufacturing tobacco cut stems

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...

Problems solved by technology

This process has the following disadvantages: a. It cannot meet the needs of improving the endoplasm of cut stems, especially for increasing flavor and reducing damage

b. The color difference of the shredded stems in the shredded tobacco is relatively large, and after being rolled into cigarettes, the appearance quality will be affected (white)
