Process implementation method for improving quality of tobacco stalks by using steam explosion and anaerobic treatment

Abstract

The invention discloses a process implementation method for improving the quality of tobacco stalks by combining steam explosion with anaerobic treatment and relates to the technical field of tobacco stalk treatment. The method comprises the following steps of: performing the steam explosion on dry tobacco stalks at first, during which the tobacco stalks are directly jetted into an anaerobic treatment device; performing the anaerobic treatment on the tobacco stalks subjected to the explosion, sealing the anaerobic treatment device, forming an anaerobic environment in the device by using negative-pressure vacuum, storing the stalks for 2 to 4h; drying the stalks to remove unnecessary moisture by a fluidized bed to control the moisture to be within 20 to 30 percent; and pressing and slicingthe treated stalks to enter the conventional stalk treatment processes, such as feeding, flash evaporation, and drying. The method replaces the vacuum conditioning, stalk cleaning by water, HT and stalk pressing of the conventional stalk treatment processes to reduce the pretreatment period of slicing stalks, improve the treatment effect, and improve and optimize the conventional stalk treatment processes.

Description

technical field [0001] The invention belongs to the technical field of tobacco stem treatment, in particular to a process realization method for improving the quality of tobacco stems by combining steam explosion and anaerobic treatment technology. Background technique [0002] The existing shredded 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 presses 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 period...

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.
