Novel threshing and redrying process based on tobacco mechanics characteristic differences

Abstract

A threshing and redrying process based on tobacco mechanics characteristic differences comprise links of primary threshing, secondary threshing, tobacco air separating, tobacco redrying and packaging. The threshing and redrying process is characterized in that according to measured tobacco mechanics characteristic indexes, tobaccos are divided into a type I of tobaccos and a type II of tobaccos, a hot air humidifying link is added between the primary threshing link and the secondary threshing link for the type I of tobaccos, tobaccos produced from the primary threshing link, the secondary threshing link and follow-up various process links are respectively redried, moisture content of the type I of tobaccos is reduced before the type I of tobaccos enter the primary threshing link, and tobaccos produced from the primary threshing link are in low-strength redrying; and the type II of tobaccos are in threshing and redrying according to existing threshing and redrying process flow. The novel threshing and redrying process is based on the tobacco mechanics characteristic differences, is complete and feasible threshing and redrying process flow and control technology for resolving the problem of tar extrusion and caking of tobacco during processing, and by the aid of the threshing and redrying process flow and control technology, threshing and redrying processing technical level and comprehensive tobacco quality further can be improved.

Description

[0001] technical field [0002] The invention belongs to the technical field of leaf threshing and redrying process, specifically a new leaf threshing and redrying process based on the difference in mechanical properties of tobacco leaves, mainly based on the change trend of mechanical property indicators such as tobacco leaf adhesion with the moisture content of tobacco leaves and ambient temperature, In the existing threshing and re-baking process, the first-level threshing and second-level threshing steps are added to the hot air leaf moistening link, and the appropriate technical parameters of the threshing and redrying process are formulated according to the adhesion of the tobacco leaves, and then realized in the threshing and redrying process, etc. To reduce the occurrence of oil-pressed tobacco leaves during tobacco leaf processing. [0003] Background technique [0004] The physical characteristics of tobacco leaves are a direct reflection of its own organizational...

AI Technical Summary

Problems solved by technology

Although the oil pressing phenomenon has attracted great attention from the tobacco industry and commerce, this phenomenon cannot be effectively controlled due to the lack of systematic research on the relationship between tobacco leaf oil pressing and external factors, and the influence of tobacco leaf structure on tobacco leaf oil production. At present, pressed oil tobacco leaves are still common
