Abstract

The invention provides a method and device for producing tobacco sheets. The production method of the tobacco sheet comprises: grinding tobacco stems, tobacco dust and tobacco scraps to obtain a slurry of tobacco stems, tobacco dust and tobacco scraps; adding a thickener to the tobacco coating solution, and then adding calcium carbonate , then add foaming agent, stir to obtain a foamy coating solution mixed with thickener and calcium carbonate; add calcium carbonate to the tobacco stem, tobacco powder and tobacco crushed slurry to obtain a slurry containing calcium carbonate; A foaming coating solution with a thickener and calcium carbonate and a slurry containing calcium carbonate are mixed, a foaming agent is added, and foamed to obtain a foam slurry, which is applied to a forming net through a foam application device, and dried through a drying unit to obtain tobacco Flakes. The preparation of the tobacco sheet of the present invention requires no additional plant fibers, high forming concentration, low liquid carrying rate, high filler retention rate, low energy consumption in the drying process, good bulkiness of the tobacco sheet, high air permeability and no color difference on both sides of the sheet.

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...
