Problems solved by technology

At present, in order to ensure the quality of expanded tobacco stems, the expanded tobacco stem production line using double cutting method in China usually adds a screening device before the expansion of the tobacco stems to screen out the thin and short stems from the raw tobacco stems as much as possible. It reduces the waste of both the quantity and quality of tobacco stem resources, and increases the production cost

Abstract

The invention relates to a fine and short tobacco stem expanding and recombining primary processing technology and a processing system, and belongs to the technical field of tobacco processing. Inapplicable fine and short tobacco stems in the microwave expanding secondary recutting technology are used as a raw material, functionality of a stem piece base material is improved from internal processing and external addition, recombining primary processing of the fine and short tobacco stems are achieved through the rolling-shredding forming technology, the use ratio of the fine and short stems in preparation of microwave expanding tobacco stem shreds, the use ratio of the tobacco stem raw material is increased by 20% or more, and the quality of the microwave expanding tobacco stem shreds is improved. The proportion of the whole shreds of the prepared expanding tobacco stem shreds reaches 65% or more, the breakage ratio is small, shred-shaped formability is higher than conventional stem shreds, the smoking quality is obviously promoted, and the primary processing technology easy to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a processing technology for expanding and recombining shredded thin and short tobacco stems. Background technique [0002] Tobacco stems account for 25%-35% of the weight of tobacco leaves. Because they have similar components to tobacco leaves and have the functions of improving the structure of cigarettes, reducing costs and reducing coke, they have always been a component of cigarette raw materials. In recent years, as the tobacco industry continues to increase its efforts to stabilize quality and reduce consumption, reduce harm and reduce coke, the technology of tobacco stem expansion and filament forming technology continues to improve, and expanded shredded tobacco stems have been widely used in cigarette production. [0003] In the production process of expanded tobacco stem shreds, thin and short stems usually account for more than 20% of the total ...
