Method for processing tobacco stem shreds

Abstract

A method for processing tobacco stem shreds comprises the following steps of: washing stems by water, stem moistening, primary stem storage, stem evaporation, stem pressing, secondary stem storage, stem shred preparation through a recutting process, charging, warming and humidifying, stem shred drying, stem shred expanding, drying and shaping, winnowing, and perfuming and dampening. The strip-shaped stem shreds obtained by the invention have the characteristics of high filling value, soft hand feel, uniform particle phase, rich elasticity, and the like, and have less wood gas and miscellaneous gas, and strong the adsorbability on essence and spices; and the stem shreds are closer to leaf shreds in the physical characteristics, are uniformly distributed in cigarette products and play the role in reducing the cost and reducing harmful components in the smoke, and simultaneously, the production stability can be significantly improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco product processing, and in particular relates to a method for producing and processing shredded tobacco stems. Background technique [0002] In the production process of cigarettes, the main principle of the cut stem processing technology in the prior art is to cut the heated and humidified tobacco stem into cut stems with a width of 0.18 mm, and quickly remove part of the moisture in the cut stems under high temperature conditions to improve the quality of the stems. Silk elasticity, filling capacity and flammability. The main process steps include: heating and humidifying the tobacco stems, cutting the cut stems, increasing the temperature of the cut stems, expanding and storing the cut stems. In the cut stem expansion process, hot air with a temperature of 150°C-170°C is used to reduce the moisture content of the cut stem from 35%-40% to about 12%. For example, the shredded tobacco stem proce...

Problems solved by technology

A method for expanding shredded tobacco disclosed in Chinese patent CN101513272A simply uses a low-temperature expansion method to expand the cut cut stems. The above-mentioned processing technology in the prior art is single, or only considers the cutting process of cut stems process, or only considered the expansion process of the cut stems, and did not comprehensively and finely consider the process from the raw material of the tobacco stems to the preparation of the cut stems that meet the needs of cigarette production. In terms of particle phase, elasticity, hand feeling, filling rate, blending rate of shredded tobacco, influence on physical indicators and sensory quality of cigarettes, utilization rate of tobacco stems, etc., the processing method is relatively extensive, resulting in the prepared shredded stems. Shredded stalks account for 10%-30%, flaky stalks account for 70%-90%, and the width of flaky stalks is mostly greater than 5mm

The addition of flaky stems to shredded tobacco leaves with a width of 0.9mm-1.0mm has a negative impact on the uniformity of tobacco blending, the stability of physical indicators and sensory quality of cigarettes, and the impact is particularly obvious as the proportion of use increases. Therefore, there are great restrictions on its use, and it also affects the quality of cigarettes
