Description
Technical Field
The invention belongs to the technical field of reconstituted tobacco production, and particularly relates to a mixing device in the production process of reconstituted tobacco by an unpowered paper-making method.
Background
The paper-making method reconstituted tobacco is to utilize raw materials such as tobacco stalk, tobacco powder, etc. to make the sheet whose character is close to or even superior to that of the natural tobacco, the tobacco raw material is extracted by water first, the dry material is made into slurry after extraction, and the slurry is made into sheet base; the extracting solution is purified, concentrated and flavored to form a coating liquid which is reversely coated on the film base to form a finished reconstituted tobacco product.
On one hand, the tobacco raw material of the paper-making reconstituted tobacco is dissolved out in the subsequent low-concentration pulping process by the part of the soluble components which are not dissolved out in the water extraction process, so that the pulp contains a large amount of saccharides, organic acids and other substances; on the other hand, the solid-liquid separation and low-concentration pulping processes in the leaching section of the reconstituted tobacco leaves by the paper-making method generate part of mixed cells and fine fibers, and the substances such as saccharides, organic acids, mixed cells, fine fibers and the like in the pulp accelerate the putrefaction and deterioration of a pulp system and the stable operation performance of a paper machine, and influence the physical and sensory quality of the finished reconstituted tobacco leaves. Therefore, in the production process of the reconstituted tobacco, pulp washing treatment is usually carried out on the pulp before pulp mixing, namely the purpose of purifying the pulp is realized through solid-liquid separation, the pulp after pulp washing is diluted and used for pulp mixing, and the consistency/dryness of the pulp obtained in the pulp washing process directly influences the papermaking adaptability of the subsequent pulp. However, when the concentration/dryness of the pulp in the pulp washing process is pursued, the requirement on the metering precision in the pulp preparation process is relatively high, which brings a problem to the dilution uniformity of the pulp after pulp washing. In the traditional process, a certain amount of dilution water is added into a pulp storage tank after pulp washing for dilution, and the mixing of the pulp and the dilution water is realized by a tank body stirrer, so that the retention time of the pulp in the tank body is short, a working blind area possibly exists in the stirrer, the uniformity of the pulp is difficult to ensure, the stability of the pulp preparation quality is affected, and the quality of a finished reconstituted tobacco product is further affected.
