Condensing resistant method and device of tobacco humidifying duct device

Abstract

The invention discloses a condensing resistant method and device of a tobacco humidifying duct device which is connected by delivery ducts and a humidifying device, and the delivery duct near the humidifying device is at least in a jacket structure, wherein an inner sleeve of the jacket structure is communicated with the humidifying device, and a jacket clearance is communicated with the inner sleeve; when in use, steam is simultaneously delivered into the inner sleeve and the jacket clearance; the steam in the inner sleeve is delivered into the humidifying device to directly humidify tobaccoleaves, and the steam in the jacket clearance has the function of heating the inner sleeve. The condensing resistant method of the tobacco humidifying duct device ensures that the steam delivered intothe humidifying device carries no condensed water so that humidified tobacco is difficult to mould, the storage time is greatly delayed, and the tobacco shred bonding condition is difficult to generate, thereby the high quality tobacco leaf humidification is ensured.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and relates to a method for preventing condensation of a tobacco humidifying pipeline device, and also relates to a tobacco humidifying pipeline device for preventing condensation. Background technique [0002] In the production process of tobacco shreds in cigarette factories, one of the steps is the cutting section of tobacco leaves, but before the tobacco leaves enter the shredding section, the tobacco leaves need to be rehydrated and humidified to loosen the tobacco leaves, increase the temperature and moisture content evenly, and improve the quality of the tobacco leaves. Softness and anti-shattering properties, in order to reduce the breakage rate of tobacco leaves in the shredding section, reduce the green miscellaneous gas in tobacco leaves, remove some volatile compounds in tobacco leaves, thereby improving the smoking quality and color of tobacco leaves, and also play a role A certain d...

AI Technical Summary

Problems solved by technology

Tobacco leaf rehydration section has certain requirements for steam, and the moisture carried by steam is required not to be too high. If the moisture contained in the steam is too high, the following consequences will easily occur: the tobacco leaves absorb too much moisture and the moisture content is too high, and it is easy to mildew during the storage stage, resulting in Tobacco leaves go bad, and the storage time is greatly shortened, and it is easy to cause serious sticking of tobacco leaves during the shredding process, which is not conducive to actual production

[0003] At present, the tobacco humidification pipe used in the tobacco moisture humidification system is a conveying pipe with an insulation layer on the outer layer. The conveying pipe is connected to a humidifying device, and a steam trap is connected to the end of the conveying pipe. The steam is transported to the humidifying device through the tobacco humidifying pipe. However, such tobacco humidification pipelines are prone to the following problems. Although under the heat preservation of the insulation layer, some steam will condense into water during the transportation process, especially in the transportation pipeline close to the humidification device. There is a steam trap for discharging condensed water, but due to the fast delivery of steam in the pipeline, part of the condensed water will still enter the humidification device with the steam and directly rehydrate the tobacco leaves, which will cause the steam to rehydrate and humidify the tobacco leaves. Excessive water will cause condensed water to be directly sprayed onto the tobacco leaves along with the steam, causing the tobacco leaves to absorb too much water, resulting in high moisture content, easy to mildew during the storage stage, resulting in deterioration of the tobacco leaves, and greatly shortening the storage time. It is easy to cause severe sticking of tobacco leaves during the shredding process, which has a great impact and loss on production
