Embodiment Construction

[0018] Preparation Examples:

[0019] Take 5 kg of tobacco stems that have undergone normal treatment processes such as tempering and alcoholization, quickly rinse with clean water to remove the dust attached to the surface, and let it dry to remove surface moisture; use a steam blasting machine to blast the tobacco stems that have removed surface moisture. The blasting working medium is Saturated with water vapor, the burst pressure is 0.8MPa, and the pressure retention time is 20 seconds. After the tobacco stems are steam-exploded, they are dehydrated and dried by suspension blast drying, so that the moisture content is kept at about 30%. After the ligninase and cellulase are activated, they are evenly added, and then the stems are stored. The temperature of the storage device is set at 35° C., the relative humidity is set at 90%, and the treatment is protected from light for 12 to 24 hours. After the enzyme treatment, the tobacco stems are cut into shreds after the enzymes...

Abstract

The invention relates to a method for improving tobacco stalk quality by combining steam explosion and enzyme treatment technology, which comprises the following steps of: performing steam explosion on tobacco stalks by using a steam explosion machine; adding lignin enzymes and cellulase into the exploded tobacco stalks; treating the tobacco stalks which are added with enzymes under the conditions of constant temperature and wet temperature, and keeping the treatment temperature of between 30 and 35 DEG C and the relative humidity of 90 percent; dehydrating and drying the tobacco stalks whichare subjected to enzyme treatment at low temperature, and controlling moisture content to about 20 to 30 percent; and finally, shredding the dehydrated tobacco stalks for cigarette production. The method for improving the tobacco stalk quality can reduce the influence of the lignin and cellulose on the tobacco stalk quality, improve the addition rate of the tobacco stalks in the cigarette production and reduce the production cost of cigarettes.

Description

technical field [0001] The invention relates to a method for improving the quality of tobacco stems by combining steam explosion and enzyme treatment technology, belonging to the field of tobacco processing. Background technique [0002] Tobacco stems are an important part of tobacco leaves, generally accounting for about 1 / 4 of the mass of the entire tobacco leaf. The content of cell wall substances such as cellulose, hemicellulose, lignin and pectin in tobacco stems accounts for about 43.8% of the dry matter mass. The high content of cellulose, hemicellulose, lignin and pectin results in strong irritation of tobacco stems, heavy miscellaneous gas, choking and astringent taste, and low aroma, which restricts the use of shredded stems in cigarette formula. Use ratio. Contents of the invention [0003] The purpose of the present invention is to provide a method for improving the quality of tobacco stems by combining steam explosion and enzyme treatment technology, so as t...
