Problems solved by technology

[0009] However, these new technologies that continue to explore the comprehensive utilization of tobacco stalks and prevent pollution are far from achieving the expected results in terms of economic and environmental benefits.
Because tobacco farmers cannot get direct profits, the results of various new technologies have not formed industrialized production and corresponding sales markets, and many hard efforts have been wasted. Every time the tobacco harvest season comes, the tobacco fields are still billowing with black smoke. Scenery, pollution remains

preparation example Construction

[0024] The preparation method of the present invention is realized through the following specific steps:

[0025] 1. Rolling and breaking the skin:

[0026] Pave tobacco straw in the material yard, remove sundries, and use rolling equipment such as light rollers, tractors and other equipment to roll, turn, and then roll tobacco straw, and destroy the skin structure of tobacco straw by extrusion and tearing , forming more cracks or micro-cracks on the surface of tobacco straw fibers, expanding the contact surface between tobacco straw fibers and biochemical agents, so that H 2 o 2 The aqueous solution A, the cellulose compound enzyme B and the inducing melt enhancer C are fully infiltrated into the interior of the tobacco straw fiber skin to perform biochemical reactions to transform lignin.

[0027] 2. Impurity removal: remove sediment and other impurities through a flat vibrating sieve.

[0028] 3. Cutting and crushing: Cut or crush the tobacco stalks into 2-3 cm short joi...

Embodiment

[0037] Spread the tobacco straw material in the yard, the thickness of the material is roughly uniform, after rolling, turning, and rolling again, then use a flat vibrating screen to remove dust and other sundries, and then cut or crush the tobacco straw with a lawn cutter or grinder into 2-3 cm long short joints or shreds, and take samples to test the content of moisture, cellulose, hemicellulose and lignin in the tobacco stalk material. And weighing 100 kg of tobacco stalk material, put it into a kneader with a volume of 1500 liters, start the kneader, and spray H 2 o 2 Aqueous solution A can also be an aqueous solution of organic solvents such as acetic acid, ethanol or methanol. After stirring evenly, disperse and sprinkle cellulose compound enzyme B after stirring evenly, then disperse and sprinkle in induction melting agent C until the tobacco straw material is in the kneader Co-kneading and soaking for 30 to 40 minutes, wherein the absolute dry weight of tobacco stalks...

Abstract

The present invention is biological conversion plus puffing process of pulping tobacco stalk and making tobacco flake and corresponding product. The process has the complete utilization of tobacco stalk and no steaming and no waste water exhaust, and the produced regenerated slurry may be used in producing low tar tobacco stuffing and making tobacco slurry together with tobacco material and seasoning. The present invention can lower cigarette cost and is environment friendly.

Description

technical field [0001] The invention relates to low-tar tobacco straw pulping and sheeting technology, in particular to a pulping and sheeting method and product combining biotechnology, life technology and mechanical manufacturing technology. Background technique [0002] China is a big country in tobacco leaf planting and tobacco production, but there are not many ways to use non-tobacco leaf resources at this stage, and the conditions for industrialization have not yet been formed, resulting in a lot of waste of resources. The main purpose of tobacco leaf planting and production is to provide raw materials for cigarettes. China needs 11.6 million mu of land every year to grow tobacco, and a large amount of tobacco leaf resources are continuously supplied to cigarette companies. However, there are 1.5 to 1.6 million tons of tobacco stalks that have no way out every year. In the past, these tobacco stalks were burned by tobacco farmers as fuel. Now, with the improvement of...
