Problems solved by technology

The technical scheme disclosed in this patent has a stable feeding material, which can avoid excessive crushing of tobacco raw materials, but has high requirements on the cleanliness of the feeding material, which requires impurity removal, and the output concentration is too low, resulting in a too low concentration of soluble matter in the leachate. Concentration consumes a lot of energy

Embodiment Construction

[0016] A kind of tobacco stem pulping process of the present invention comprises the following concrete steps:

[0017] (1) Transport the mixture of tobacco stems and water with a mass concentration of 10%-18% (preferably 15%) to a two-stage medium-consistency refiner in series for deflaking and pulping;

[0018] (2), and then transport the deflated slurry to a high-consistency hydraulic pulper, the slurry mass concentration is 10%-18% (preferably 15%), and the pulping temperature is kept at 60-80°C (preferably 70°C) , the pulping time is 15-30min (preferably 25min);

[0019] (3) After pulping is completed, it enters the leaching stage, and after reprocessing, papermaking is carried out;

[0020] (4) Soak the tobacco stems and sheets after making in heated water, the water ratio is 4-6 times (preferably 5 times) the weight of the tobacco, the temperature is kept at 50°C-70°C (preferably 60°C), and the soaking time is 1 -2h (preferably 1.5h);

[0021] (5) After leaching, the...

Abstract

Disclosed is a tobacco stem pulping process. The process includes the following steps: delivering a mixture of tobacco stems 10-18% in mass concentration and water to a middle-concentration pulping machine in two-stage series for defibering pulping; delivering pulp after being defibered to a high-concentration hydrapulper, wherein mass concentration of the pulp is 10-18%, pulping temperature is maintained to be at 60-80 DEG C, and pulping time is 15-30min; entering a leaching stage after pulping is completed, and manufacturing paper with the pulp after retreatment. The tobacco stems are properly defibered, so that uniformity in tobacco stem pulping is realized, and smooth extraction of soluble substances in the process of leaching is facilitated; due to adoption of high-concentration grinding and high-concentration hydrodynamic pulping, overmuch tiny broken tobacco stems cannot be generated as high-concentration pulping does, and macromolecular substances like pectin cannot be dissolved out too much, so that purification of leaching liquid and improvement of sensory quality are facilitated, favorable factors in two aspects are combined, products are enabled to be good in bulk, higher in softness and excellent in liquid absorbing performance, and physical quality and sensory quality are improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a tobacco stem pulping process. Background technique [0002] The papermaking method of reconstituted tobacco leaves, commonly known as tobacco flakes, is to use tobacco waste such as tobacco stems, tobacco powder and chips as the main raw materials, impregnate the tobacco raw materials with water, and then separate the water-soluble and insoluble substances in the tobacco from solid-liquid. Equipment and technology, beating the insoluble matter such as tobacco fiber to make it a slurry suitable for paper machine making, and then making a fiber sheet through a paper machine, and at the same time, the water-soluble matter is concentrated and added back to the sheet. After drying It is reconstituted tobacco leaves by papermaking method. This process technology can improve the chemical composition of tobacco, and has a good effect on reducing tar and harm. ...
