Problems solved by technology

The coating rate is closely related to parameters such as the surface area of ​​the substrate, dryness and filling value. Due to the low filling value, poor air permeability, and insufficient surface roughness of the substrate made by the wet papermaking method, it is difficult to achieve a coating rate of ≥ 46%. Recharge≥6.0cm 3 / g indicator

Abstract

The invention discloses a dry-type paper-making method reengineering tobacco production process which is characterized in that tobacco fibrous raw materials, or fluff pulp fibrous raw materials, or tobacco and fluff pulp fibrous raw materials are manufactured into base pieces with a high filling value through a dry-method paper-making machine by utilizing an airflow sedimentation method, tobacco powder and rubber mixture are sprayed on the front side and the reverse side of each core base piece, the base pieces are made into tobacco sheet finished products through drying and follow-up procedures, a negative pressure vacuum drawing way is adopted for spraying, the sprayed tobacco powder and the rubber mixture are absorbed in the core base pieces in an attaching mode, and the process is a way of spraying-drying and secondary spraying-drying. A coating rate of the manufactured tobacco sheet finished products is larger than or equal to 46%, the filling value is larger than or equal to 6.0 cm<3> / g, and water content is smaller than or equal to 12%.

Description

technical field [0001] The invention relates to a production process of dry papermaking reconstituted tobacco leaves. Specifically, the outer fiber or tobacco fiber is made into a core layer substrate through a dry air flow forming machine, and then the substrate is sprayed with a mixture of smoke powder and glue on both sides and then dried. Dry molding belongs to the technical field of reconstituted tobacco leaves in the cigarette industry. Background technique [0002] The reconstituted tobacco leaf in the cigarette industry is the tobacco dust, broken stems, fragments and other substances produced during the cigarette processing process, which are processed and recombined into sheet or silk regenerated tobacco products (also called tobacco flakes). It has the advantages of saving tobacco leaf raw materials and flexibly regulating the physical and chemical properties of cigarettes. The known production methods of reconstituted tobacco mainly include rolling method, thick...
