Processing technique for manufacturing golden tobacco shreds

Abstract

The invention discloses a processing technique for manufacturing golden tobacco shreds. The technique is characterized by comprising the processes of tobacco leaf selection, low-strength loose moistening, tobacco sheet selection, low-temperature storage, low-moisture flexible shredding and low-temperature leaf shred drying. The technique has the advantages that: (1) the prepared tobacco shreds are golden and have good appearance quality; on the one hand, the tobacco leaves with poor appearance quality in the tobacco leaf raw material are removed by adopting the tobacco leaf and tobacco sheet selection processes so as to improve the purity of the golden tobacco leaves in the tobacco leaf raw material; on the other hand, the tobacco sheet moisture content during shredding and the knife door pressure of a shredder are reduced by adopting the low-moisture flexible shredding process so that the tobacco shreds producing brown stains after shredding are reduced; and (2) the prepared tobacco shreds have predominant fragrance and good sense quality. The tobacco sheets are treated by adopting the low-strength loose moistening, low-temperature storage and low-temperature drying processes so as to reduce the return air temperature of a tobacco sheet loose moistening device, the storage environment temperature, the leaf shred drying temperature and the tobacco sheet heating time and reduce the fragrance loss of the tobacco sheets during preparing the shreds.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a processing technology for making golden shredded tobacco. Background technique [0002] The color of tobacco shreds is closely related to its sensory quality, physical quality and chemical composition. Golden leaf silk has the characteristics of coordinated chemical composition, outstanding aroma, comfortable taste, good combustibility, high filling value, and strong resistance to crushing. Increasing the proportion of golden leaf shreds in cigarettes can improve the sensory quality and appearance quality of cigarettes, and improve the grade of cigarettes. [0003] The existing flue-cured tobacco leaf processing technology is to unpack, slice, loosen and regain moisture, feed, match leaves and store leaves, shred and dry the tobacco leaves after the initial roasting, after beating, re-roasting, packaging and aging and other processes to make shredded leaves that me...

AI Technical Summary

Problems solved by technology

The existing flue-cured tobacco processing technology can meet the requirements of large-scale continuous production of cigarettes, but there are the following deficiencies: First, the appearance quality of cut tobacco is poor

The reason is that on the one hand, some of the tobacco leaves in the tobacco raw materials have poor appearance quality, which affects the appearance quality of the cut tobacco; The knife door pressure of the cutting machine is relatively high (0.2-0.4MPa), which causes browning of the shredded leaves; second, the process
