Abstract

The invention relates to the technical field of tobacco leaf processing, and particularly discloses a tobacco leaf blending method which specifically comprises the following steps: extracting tobaccoraw materials to obtain tobacco insoluble substances and tobacco extract liquor; carrying out microwave treatment on tobacco insoluble substances, grinding into slurry, adding calcium carbonate fillerinto the slurry, molding the slurry, and drying to obtain a substrate; adding a compound enzyme agent into the tobacco extract liquor, and carrying out enzymolysis reaction; then adding fructose andamino acid, adjusting the pH value to 7-8.5, reacting at 60-75 DEG C, and carrying out rotary evaporation and concentration to obtain a tobacco concentrated solution; uniformly mixing the tobacco concentrated solution with nano zeolite, sodium lignin sulfonate and organic acid to obtain a coating solution; and finally, coating the coating liquid on a substrate, and drying to obtain the reconstituted tobacco. According to the tobacco leaf blending method, waste materials generated in the cigarette production process are effectively utilized, and resources are saved; and the method has the effects of reducing harm and tar, reducing the content of harmful substances in the reconstituted tobacco and improving the quality of the reconstituted tobacco.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf processing, and in particular relates to a tobacco leaf preparation method. Background technique [0002] When cigarette factories produce cigarettes, a large amount of tobacco waste will be generated, such as short stems, tobacco dust, low-grade tobacco leaves, etc. The direct disposal of tobacco waste will cause waste of resources and loss of economic benefits. Reconstituted tobacco leaf, also known as tobacco flakes, is an important form of tobacco waste reuse, which has great environmental protection and economic value. Powder and some low-grade tobacco leaves are first processed into a base sheet according to the papermaking method, and the base sheet is coated and dried, and finally made into a thin sheet close to natural tobacco leaves. Like ordinary cigarette products, after the tobacco sheet is burned, the smoke contains a variety of harmful chemical substances, mainly tobacco-speci...
