Process for improving crushing resistance of rolled slices

Abstract

The invention relates to a process for improving the crushing resistance of rolled slices, which comprises the following steps of: (1) impregnating and defibring externally-added fibers in alkali liquor, and performing extrusion and oven-drying to obtain defibred dry fibers; (2) crushing and uniformly mixing 10 to 20 weight percent of defibred dry fiber, 70 to 80 weight percent of tobacco material and 2 to 10 weight percent of methylcellulose to form mixed fibers; (3) uniformly mixing the defibred dry fibers and slice glue, and then mixing the mixture, a phosphoric acid, glycerol and water toobtain slice glue mixed fibers; (4) mixing the mixed fibers and the slice glue mixed fibers according to the weight ratio of 1:1-2, and storing the mixture in a storage tank; and (5) rolling and forming the raw material, drying and cooling the formed raw material, and slitting the raw material to obtain slice shreds. Through the process, the toughness of tobacco slices is improved; and the prepared tobacco slices have strong mechanical strength and high crushing resistance.

Description

technical field [0001] The invention relates to a preparation method of a tobacco sheet, in particular to a process method for improving the crush resistance of a roll-pressed sheet. Background technique [0002] In the process of manufacturing tobacco sheets, in order to improve the strength of the sheet and increase its utilization rate, it is necessary to go through the process of defibrating and adding fibers. The basic requirement is to separate the raw materials under the premise of minimizing the loss of fibers and consuming less power. Form individual fibers or fiber bundles to make the slurry have a certain specific surface area and interweaving performance, and then mix the fibers with tobacco powder chips, tobacco stems and other auxiliary materials to create the necessary conditions for the recombination between fibers. [0003] The commonly used fiber separation methods in the cigarette industry are mechanical fiberization, hydrolysis fiberization and NaOH alkal...

Problems solved by technology

In the mechanical defibration process, because a mechanical force is applied to the raw material, a large force is also applied to the fiber itself, which will affect the strength of the fiber and change the mechanical properties of the fiber, etc.; the simple hydrolysis of the fiber will take a long time , the fibrillation is not complete, which affects the follow-up process; NaOH lye treatment, the pH of the lye is too high to be controlled, and it is easy to cause part of the lye residue, which affects the taste of cigarette products

At present, the commonly used fibering process is mostly to mix the hydrolyzed and dried fibers with CMC, tobacco powder fragments, and short-stem sticks in proportion, and then crush and mix them. Toughness and resistance to crushing
