Abstract

The invention provides a production method and device for tobacco sheets. The production method includes: grinding tobacco stems, tobacco powder and tobacco residue to obtain tobacco stem, tobacco powder and tobacco residue pulp; adding a thickener into tobacco coating liquid, adding calcium carbonate, adding a foamer, and stirring to obtain foamed coating liquid mixed with the thickener and calcium carbonate; adding calcium carbonate into the tobacco stem, tobacco powder and tobacco residue pulp to obtain pulp containing calcium carbonate; mixing the foamed coating liquid with the pulp, adding the foamer for foaming to obtain foamed size, applying the foamed size on a forming net through a foam applying device, and drying through a drying unit to obtain the tobacco sheets. The production method is needless of adding plant fiber, high in forming concentration, low in liquid carrying amount, high in filler retention rate and low in energy consumption in the process of drying, and the tobacco sheets are high in bulkness and breathability and free of chromatic aberration between two faces.

Description

technical field [0001] The invention relates to a method for preparing tobacco sheets, belonging to the technical field of tobacco sheet production. Background technique [0002] Tobacco sheet is a reconstituted tobacco leaf made by recombining low-grade tobacco leaves, discarded tobacco powder, tobacco stems, tobacco leaf fragments and additional plant fibers in the cigarette production process. Papermaking sheet manufacturing technology has become the main production method of tobacco sheet because of its advanced process principle and manufacturing technology. [0003] The production of tobacco sheets by the papermaking method mainly includes two aspects: on the one hand, waste tobacco stems, tobacco powder, tobacco shreds, and additional plant fibers are used as raw materials through a series of beating treatments to make sheet base paper. On the other hand, the liquid extracted from raw materials such as discarded tobacco stems, tobacco powder and tobacco shreds is com...
