Abstract

A tobacco stem shred preparation method includes steps of pretreatment of tobacco stems, microwave expansion of tobacco stems, moisture regaining of expanded tobacco stems, tobacco stem shredding, stem shred screening and winnowing, stem shred feeding, second tobacco shred expansion, stem shred flavoring and the like. The prepared tobacco stem shreds are similar to tobacco shreds in appearance and shape, have the advantages of high filling performance, soft flavor and low stimulation in sensing quality and the like and are good in suitability for smoke.

Description

technical field [0001] The invention belongs to the technical field of tobacco preparation, in particular to the technical field of shredded tobacco stems. Background technique [0002] Tobacco stems account for about 25-30% of the weight of tobacco leaves, and a large amount of tobacco stems will be produced during the cigarette production process. In my country, hundreds of thousands of tons of tobacco stem resources are discarded every year, resulting in waste of resources and environmental pollution. However, high-quality shredded stems can increase the filling value of shredded tobacco, reduce the tar content of smoke, and improve the quality of cigarette products. It is an important component of the cigarette leaf group formula. Therefore, the effective use of tobacco stems to prepare high-quality shredded stems has always been the content of research and discussion in the tobacco industry. [0003] Chinese patent application 200810233445.9 discloses a method for pr...
