Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0014] like figure 1 As shown, the existing dip coating coating method is to pass the substrate 6 with a dryness of about 75% through a pair of counter-rotating rubber rollers 8, and there is a coating liquid (dip 6) with a height of ~200mm between the roller surfaces at the passing place. Paste) is impregnated on the substrate 6. After coating, the sheet 5 goes up to the set height along the inclined surface and then enters the drying box 1 horizontally for drying. Since the substrate 6 adopts a strong drying method on the large cylinder 11, and the small cylinder 10 The role of the film is limited to state adjustment, not beneficial to eliminate the poor smoothness of both sides, so the front and back of the substrate 6 has poor smoothness before coating, although after coating, the sheet 5 is guided upward by the copper mesh 12 from the fixed-lengt...

Abstract

The invention disclose a method for reducing difference on two sides of paper-making reconstituted tobacco, which adopts the moistening manner of quantitatively spraying atomized tap water on the back of a coated substrate through an atomizing nozzle to increase the liquidity of coating liquid on the back of a sheet, and prompt the coating liquid on the back to further permeate to the front, and the distribution difference of coating weight on the front and the back is reduced, and uniformly front and back coating weight of the sheet is achieved. The method has less input, simple control, and obvious effect. The vertical height between the atomizing nozzle and the sheet is 250 to 350 mm; the centre line of the nozzle is vertical to an oblique plane of the sheet; the mist granularity is not greater than 300 micrometers; and the spraying volume for the sheet is 150 to 250 g per square meter.

Description

technical field [0001] The invention relates to a method for reducing the two-sided difference of reconstituted tobacco leaves by the papermaking method. Specifically, the two-sided difference of the finished sheet after drying due to the uneven coating amount on the front and back sides after substrate coating is reduced by means of spray humidification, which belongs to the reconstituted tobacco leaf technology in the cigarette industry. field. Background technique [0002] Reconstituted tobacco leaves are 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). The known production method of reconstituted tobacco leaves is mainly the wet papermaking method. Its characteristics follow the traditional pulping and papermaking technology. The tobacco raw materials (tobacco stems, tobacco powder, tobacco powder...
