Description
The priority of the pulp spraying coating device that a kind of dry method of paper-making method of Chinese invention patent application reconstituted tobacco that the application claims applying date is on March 10th, 2014, application number is CN2014100860987 is produced.
Technical field
The present invention relates to tobacco-containing material manufacturing technology field, relate to a kind of pulp spraying coating device being applicable to dry method of paper-making method reconstituted tobacco and producing.
Background technology
Reconstituted tobacoo is also known as reconstituted tobacco, recombination tobacco leaf, homogeneous tobacco leaf.Primarily of offal, fragment, offal or discarded tobacco leaf, the compositions such as Extra Section fiber, adhesive and other additives.Reconstituted tobacco has that cost is low, fillibility well and the advantages such as tar content to be reduced in flue gas, be widely used in production of cigarettes as tobacco product.The goods of reconstituted tobacco start from the 1950's, and manufacture method mainly contains roll-in method, thick slurry processes and paper process, and current paper process is the main manufacture of reconstituted tobacco.Paper process is divided into again wet papermaking method and dry method of paper-making method, no matter is that wet papermaking legal system makes reconstituted tobacco, or dry method of paper-making method reconstituted tobacco, and all or must be sprayed on substrate by the coating of tobacco correlative, drying becomes reconstituted tobacco.Wet papermaking method reconstituted tobacco be after Yankee cylinder and little cylinder are dried, adopt apparatus for coating the solubility tobacco material after concentrated and additive to be made at substrate coating solution at substrate surface, beat the finished product that sheet becomes reconstituted tobacco after drying.Dry method of paper-making method reconstituted tobacco due to sheet fiber molding mode different with the bonding state of shaping rear fiber, adopt the method carrying out spraying under suction function, be coated on substrate by the pulp spraying that tobacco powder and other correlatives are made, the solid content of spraying and viscosity are far away higher than wet papermaking method coating fluid.
