Preparation method of tobacco flakes through tobacco stems using biochemical machinery method

Abstract

The invention discloses a preparation method of tobacco flakes through tobacco stems using a biochemical machinery method. The preparation method of the tobacco flakes through the tobacco stems using the biochemical machinery method comprises (1) conducting pretreatment to tobacco stem materials, (2) putting the tobacco stems into white rot fungi solution, then adding water, preparing biological enzymolysis solution, conducting enzymolysis of the tobacco stems in the biological enzymolysis solution, (3) mixing urea which is 4-10 % of the tobacco stem materials by mass and sodium hydroxide which is 5-15 % of the tobacco stem materials by mass, and adding water to dissolve to obtain lignin degradation solution, spraying the lignin degradation solution into the biological enzymolysis solution to obtain biochemical reaction soak solution, soaking the tobacco stems into the biochemical reaction soak solution and generating biochemical reaction, (4) conducting concentrate fluid exhaustion treatment, (5) conducting pulp abrading and pulp washing treatments, (6) conducting purifying treatment, acquiring tobacco stem pulp, (7) manufacturing tobacco base flakes, and (8) obtaining the tobacco flakes. The preparation method of the tobacco flakes through the tobacco stems using the biochemical machinery method can remove the lignin in the tobacco stems effectively, reserves tobacco ingredients in the tobacco stem, and thus turns the waste to wealth, and is safe and environment friendly.

Description

technical field [0001] The invention relates to a production process of tobacco flakes, in particular to a method for preparing tobacco flakes from tobacco stalks by using a biochemical mechanical method. Background technique [0002] my country is a big tobacco consumption country and a big tobacco production country. After picking tobacco leaves every year, more than 4 million tons of tobacco stalks will be produced. Tobacco stalk cleaning is an important agricultural task in tobacco leaf production, and it is also a major problem that plagues tobacco farmers and the tobacco sector. It is understood that in some places, the tobacco stalks are either burned, discarded, or returned directly to the field. However, a large number of pathogens are parasitic in tobacco stalks, which not only easily spreads diseases such as black shank, anthracnose, and green orange disease, but also causes waste of resources and pollution of tobacco fields, becoming an "invisible bomb" that affe...

Problems solved by technology

[0008] The purpose of the present invention is to provide a method for preparing tobacco flakes from tobacco stalks by using a biochemical mechanical method, which can effectively remove lignin in tobacco stalks, and at the same time retain most of the tobacco components in tobacco stalks, turning waste into treasure It is also safe and environmentally friendly, and overcomes the defects of high chemical dosage, harsh reaction conditions, and large environmental pollution in chemical pulping. It can also overcome the defects of high energy consumption and low fiber strength in mechanical pulping, and overcome the tobacco-like substances in tobacco stems. Defects that it is difficult to keep and that tobacco stalk flakes cannot be used instead of tobacco leaves
