Problems solved by technology

[0005] Tobacco sheets are coated by dip coating or roll coating, and the concentrated extract (ie, coating liquid) is coated on the base by continuous reflux circulation, that is, the liquid feeds a piece of base dip coating-coating liquid reflux , the disadvantages of circulation in turn are: 1. It is difficult to control the coating amount of the coating process, the coating uniformity is not good, and the coating rate is also low, generally below 50%; 2. During the coating process, the backflow coating liquid, Inevitably, fine fibers in the film base and damaged pieces of the film base will be brought into the coating liquid, which will affect the quality of the coating liquid; 3. The continuous reflux of the coating liquid will gradually increase its viscosity and solid content , which not only causes poor fluidity of the coating liquid, affects the stability of the continuous production of the sheet, but also directly affects the appearance and sensory quality of the sheet

Abstract

The invention provides a device and method for producing tobacco sheets. The production method of the tobacco sheets includes: tobacco raw materials are extracted in an extraction tank to be separated, insoluble substances are pulped and placed on a screen to be made into sheet bases, and obtained extract liquor is filtered through a filter screen and concentrated to obtain coating liquid; a part of coating liquid is foamed by using a foam generator to obtain foam coating liquid, the foam coating liquid is coated on the sheet bases by using a foam spraying process, and the other part of coating liquid is used for coating the sheet bases sprayed by foams again by using a mist spraying process to obtain wet sheet bases coated twice; sound wave or ultrasonic wave processing is performed on the wet sheet bases coated twice, vibration defoaming is performed on small foams to accelerate seepage of the coating liquid, and the coating liquid coated on the surfaces of the wet sheet bases is prevented from transferring to a nylon mesh belt; and the processed wet sheet bases are dried, and finished products of the tobacco sheets are manufactured after slitting of the sheet bases. The tobacco sheets manufactured by the method are large in coating quantity, high in coating evenness and good in air permeability.

Description

technical field [0001] The invention relates to a tobacco sheet production device and method, and belongs to the technical field of papermaking tobacco sheet production. Background technique [0002] Tobacco sheet is processed tobacco waste such as tobacco stems, tobacco powder and low-grade tobacco leaves in the cigarette production process to produce sheet-shaped tobacco regenerated raw materials that meet the requirements of cigarette formula. Tobacco sheet is blended with natural tobacco leaves in a certain proportion Made into cigarettes. [0003] There are three main processes for manufacturing tobacco sheets, namely: roll pressing method, thick pulp method and paper-making method. Among them, the paper-making method has the comprehensive advantages of various processes and currently occupies a dominant position. The production technology of paper-making tobacco flakes adopts a two-step processing process: adding water to soak tobacco stems, tobacco powder and low-gra...
