Method for realizing process for improving tobacco stem quality by applying steam explosion and microwave radiation technology

Abstract

The invention discloses a method for realizing a process for improving tobacco stem quality by applying steam explosion and microwave radiation technology and relates to the technical field of tobacco leaf and tobacco stem processing. Steam explosion, a fluidized bed drying and microwave radiation are applied to replace stalk water washing, HT (tunnel tobacco shred steam conditioner), stem steam, stem storage and stem pressing procedures in the conventional cut stem process. The method comprises the following steps of: firstly, performing steam explosion on tobacco stems, drying the tobacco stems by using a fluidized bed to remove redundant moisture and controlling the water content of the tobacco stems to be between 20 and 30 percent; secondly, performing microwave radiation on the exploded and dried tobacco stems by using a microwave irradiator; thirdly, cutting the irradiated tobacco stems into shreds and treating the shreds by the conventional cut stem treatment procedure; and finally adding other materials into the cut stem and performing flash evaporation and drying on the mixture to obtain a raw material for the production of cigarettes. The method has the advantages of improving and optimizing the conventional cut stem treatment process, shortening the pretreatment period of tobacco stem cutting and lowering the cost of the tobacco stems process.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf and stem processing, in particular to a process realization method for improving the quality of tobacco stems by combining steam explosion and microwave radiation technology. Background technique [0002] The existing cut stem treatment process generally carries out vacuum rehydration and water washing of the stems first, and then steams the stems, stores the stems, HT secondary steaming of the stems, secondary storage of the stems, and pressing the stems to make the tobacco stems To meet the requirements for cut stems, the tobacco stems are then shredded, fed, flashed and dried to produce cut stems that meet the requirements of cigarette formula for cigarette production. However, in the existing process, the vacuum moisture regain, the stems are washed with water, and then the stems are steamed and stored by HT. Not only the process is complicated, the space is large, but also the treatment ...

AI Technical Summary

Problems solved by technology

However, in the existing process, the vacuum moisture regain, the stems are washed with water, and then the stems are steamed and stored by HT. Not only the process is complicated, it takes up a lot of space, but also the treatment cycle is long and the moisture regain effect of the dry tobacco stems is poor.
