Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 2 and image 3 Shown, the tobacco leaf pretreatment method in the present embodiment tobacco shredded production process, it comprises the following steps:

[0034] (1) Loosen and regain moisture in the laminar tobacco.

[0035] (2) Digest the loose and rehydrated tobacco leaves through the steeping equipment. According to the different grades of the tobacco leaves, the hot water temperature of the steeping equipment is set at any temperature between 70-100°C, and the tobacco leaves are transported to the In the soaking equipment, after soaking in hot water for any time between 5-15 minutes, it is then transported to the spiral draining device for draining. The immersion equipment includes a hot water tank 11, one end of the upper part of the hot water tank 11 is provided with a stainless steel mesh conveyor belt inlet...

Abstract

The invention discloses a tobacco leaf pretreatment method during tobacco primary processing. The tobacco leaf pretreatment method comprises the following steps of: performing dispersion and moisture regaining on a tobacco, conveying to digesting equipment for digesting through conveying equipment, wherein temperature of hot water of the digesting equipment is set between 70 and 100 DEG C; digesting the tobacco for 5 to 15 minutes; conveying the tobacco to a draining device for draining; spraying to add a lining; dehumidifying by hot air; and after reducing the water to 22 percent, laying the leaves for 15 to 30 minutes and cutting. In the tobacco leaf pretreatment method, the tobacco is dispersed and subjected to moisture regaining, so that the storage time of the tobacco added with the lining can be reduced, the working efficiency is improved and the time is totally reduced by 100 minutes due to a tobacco digesting mode; furthermore, the cigarette sense smoking quality is improved, the chemical constituents of a cigarette are coordinated, and harmful substances, such as oil tar of smoke, smoke nicotine, CO and N nitrosamine in the cigarette (TSNAs), can be reduced greatly; therefore, the quality of cigarettes is improved.

Description

technical field [0001] The invention relates to a method for pretreatment of tobacco leaves before shredded tobacco. Background technique [0002] As consumers pay more and more attention to health, reducing harmful substances in cigarette smoke has become an important content of cigarette research and development, so it is of great significance to study technologies for reducing harmful substances in cigarette smoke. [0003] At present, the general method of pretreatment of tobacco leaves before tobacco shredding is: after loosening the sheet tobacco and regaining moisture, spraying and adding lining to regain moisture, after storing the leaves for 2-4 hours, and then going through the tobacco sheet heating process, shredding is carried out. Such as figure 1 shown. The advantage of doing this is that it can keep the original taste in the tobacco leaves as much as possible, but its storage time is longer, which affects the working efficiency of the workshop; The comfort ...
