Bulk tobacco formula threshing and redrying processing technology

Abstract

The invention discloses a bulk tobacco formula threshing and redrying processing technology. The processing technology comprises steps of humidifying leaves through vacuum; selecting the leaves; paving and cutting off the leaves based on the formula; automatically placing the leaves into a formula library; threshing and redrying leaf laminas; threshing and redrying petioles; and packing the leaves. The processing technology is advantageous in that the process for threshing and redrying bulk tobacco is simpler than the process for threshing and redrying bundle tobacco, the processing intensity of leaf conditioning and tobacco strip redrying processes is reduced, the threshing load is reduced, energy is saved, the loss due to tobacco cutting is reduced, the loss of the tobacco aroma during a processing process is reduced, the appearance and quality of finished tobacco strips after threshing and redrying are improved, and the application range of the tobacco strips is expanded. In the process of bulk tobacco formula threshing and redrying, the leaves are cut off, and the leaf laminas and petioles are respectively processed through threshing and redrying. Different processing intensity and customized technology are adopted according to the difference of physicochemical properties of leaf laminas and petioles of the tobacco strips, so that the tobacco group formula is more uniform, internal chemical compositions of the tobacco strips are coordinated, the tobacco strips are high in compatibility, has prominent features and distinct styles, and can more meet demands of cigarette enterprises.

Description

technical field [0001] The invention relates to the technical field of threshing and redrying in tobacco processing, in particular to a processing technology for threshing and redrying of loose tobacco formula. Background technique [0002] Tobacco is an agricultural product. During the field production process, some sandy soil adheres to the surface of the tobacco leaves. Some sandy soil will be removed during the tobacco farmers’ collection and primary curing process, but the natural soil content of the tobacco leaves after primary curing is still about 1.1%. [0003] With the change of tobacco leaf planting mode and initial curing method, the cigarette industry has higher and higher requirements for the grade purity of tobacco leaves. The disadvantages of traditional tobacco leaf classification and purchase have become increasingly prominent, such as low grade purity, labor and time-consuming, easy to mold Change, easy to adulterate to make false and not conducive to thre...

AI Technical Summary

Problems solved by technology

[0006] 1. The existing threshing and re-baking process is established based on the main characteristics of tobacco raw materials and single-grade processing, which cannot effectively adapt to the technological requirements of threshing and re-baking of the raw material formula of loose tobacco

[0007] 2. The process of laying leaves and removing handles is manually placed, which is easily affected by human factors, and the feeding of tobacco leaves cannot be automatically controlled, especially not suitable for the brand formula proposed by cigarette industry enterprises in recent years. Processing requirements for blade specification consistency

[0008] 3. The vacuum rehydration process is not taken as an essential process, and there are some threshing and re-baking tobacco slices that have not undergone the initial treatment process of vacuum rehydration to kill insects, kill eggs and remove green miscellaneous gases

[0009] 4. The leaf moistening and moisture regaining equipment has a high processing intensity on the tobacco leaves. The tobacco leaves are heated at a high temperature and for a long time. Some high-grade tobacco leaves are dark in color, which affects the appearance quality of the tobacco leaves

[0010] 5. The processing intensity of redrying tobacco leaves is high, the tobacco leaves are heated at a high temperature and for a long time, and some of them have transitional redrying, resulting in a large loss of aroma in high-grade tobacco leaves, which affects the quality and use value of tobacco leaves.
