Problems solved by technology

Using this puffing method, the shredded leaf can get a higher puffing rate, generally up to (80-100)%, but because the puffing rate is too high, the intrinsic quality of the shredded leaf itself is changed, and the shredded leaf has no tobacco aroma of its own.
Therefore, the shredded leaves used for cigarettes cannot be fully expanded, and only about 10% of the expanded cut tobacco can be added to the cigarettes. In addition, the expansion tank is required to withstand a high pressure of 2Mpa, and its manufacturing requirements and manufacturing costs are relatively high. The expansion medium carbon dioxide and Freon pollute the environment

Embodiment Construction

[0014] A kind of leaf shreds rapid expansion drying method (equipment such as figure 1 shown), has the following preparation process:

[0015] A. Feeding: High humidity shredded leaves (moisture content is 22-32%) enter the feed air lock 2 from the feed cover 1, and the feed air lock 2 sends the shredded leaves to the looser 3, and isolates the air ;

[0016] B. Filament heating: The leaf silk is fully mixed with the steam sprayed from the steam injection pipe 4 in the loosener 3 and heated rapidly. The leaf silk enters the hot air pipeline 5 from the looser 3, and is heated by (200-300)°C hot air ( Superheated steam) is sent into drying tower 6;

[0017] C, shredded leaf puffing: the shredded leaf is fully heat-exchanged with the hot air in the drying tower 6, and is dehydrated rapidly in about 5 seconds, and the moisture is dried from (22-32)% to 13%;

[0018] D. Discharging: The puffed shredded leaves are sent to the cyclone separator 8 by the pipeline 7. After the gas m...

Abstract

The present invention relates to the tobacco processing process and is especially the puffing and drying process of cut tobacco. The tobacco process includes feeding material, heating cut tobacco, puffing and discharge. The beneficial effects of the present invention includes reserving tobacco fragrance in cut tobacco, reducing the green and sundry smell in cut tobacco, converting the color of low-grade cut tobacco, raising the puffing rate of cut tobacco, reducing cost of cigarette, raising filled tobacco amount, decreasing tar content in cigarette, making cut tobacco soft, loose elastic and no oxidation and browning, killing bacteria and other toxic microbes and producing no environmental pollution.

Description

technical field [0001] The invention relates to a tobacco preparation process, in particular to a puffing and drying method for shredded leaves. Background technique [0002] The traditional shredded leaf puffing method is to use carbon dioxide or freon as the medium, soak the wet shredded leaf in a high-pressure airtight container filled with carbon dioxide or freon solution, open the container cover after a period of time, and the carbon dioxide or freon will evaporate quickly under normal temperature and pressure , resulting in rapid dehydration of the leaf silk cells, causing the leaf silk to curl, thus obtaining puffing. Using this puffing method, the shredded leaf can get a higher puffing rate, generally up to (80-100)%, but because the puffing rate is too high, the intrinsic quality of the shredded leaf itself is changed, and the shredded leaf has no tobacco aroma of its own. . Therefore, the shredded leaves used for cigarettes cannot be fully expanded, and only abo...
