Problems solved by technology

However, increasing the coating speed will inevitably reduce the contact time between the blank substrate and the coating liquid. Under the premise that the penetration rate of the coating liquid on the substrate remains unchanged, the coating rate will also be reduced accordingly.
In addition, after the coating speed is increased, since the penetration rate of the coating liquid remains unchanged, part of the coating liquid will remain on the surface of the substrate. During the drying process, the remaining coating liquid will form a solid protective film on the surface of the substrate. , to block the evaporation of moist

Embodiment 1

[0089] (1) Preparation of blank coating liquid: extract 10 g of tobacco stems (place of origin: Yunnan) with 500 g of water, the extraction temperature is 80 ° C, the extraction time is 20 min, filter to obtain the filtrate, and concentrate the filtrate to a density of 1.3 g / mL to obtain liquid A. Mix 12g of tobacco leaves (place of origin: Fujian) with 8g of tobacco powder sticks (produced by Longyan Cigarette Factory), add 1000g of water for leaching, the leaching temperature is 80°C, and the leaching time is 20min, filter to obtain the filtrate, and concentrate the filtrate to The density was 1.2g / mL, and liquid B was obtained. Mix liquid A and liquid B at a mass ratio of 1:1 to obtain a blank coating liquid.

[0090] (2) Take 100 g of the blank coating solution, add 5.0 mg of eugenol methyl ether, and stir evenly to obtain coating solution 1.

Embodiment 2-5

[0092] Take multiple blank coating solutions, each 100g, add 1mg, 2.5mg, 7.5mg, 10mg of eugenol methyl ether respectively, and stir them evenly to obtain coating solutions 2-5. Wherein, the preparation method of the blank coating solution is the same as in Example 1.

Abstract

The invention belongs to the field of reconstituted tobaccos and particularly relates to a coating liquid for the reconstituted tobacco. The coating liquid for the reconstituted tobacco comprises methyleugenol and a coating liquid A, the weight ratio of the methyleugenol to the coating liquid A is less than 0.01%:1 and is not 0, wherein the coating liquid A is prepared through a method comprisinga step (1), a step (2), a step (5), an optional step (3) and an optional step (4) as follows: (1) extracting tobacco leftovers with water, and implementing solid-liquid separation to obtain a first liquid-phase material; (2) extracting a tobacco material with water, and implementing solid-liquid separation to obtain a second liquid-phase material; (3) concentrating the first liquid-phase materialto obtain a first concentrated solution; (4) concentrating the second liquid-phase material to obtain a second concentrated solution; (5) mixing the first liquid-phase material with the second liquid-phase material, or mixing the first concentrated solution with the second concentrated solution. The invention further relates to the preparation method of the coating liquid. The permeation rate of the coating liquid on a substrate is high, and the sensory quality of the reconstituted tobacco is not affected.

Description

technical field [0001] The invention belongs to the field of reconstituted tobacco leaves, and in particular relates to a coating solution for reconstituted tobacco leaves and a method for preparing the coating solution. Background technique [0002] In the reconstituted tobacco leaf process, the coating rate is the limiting factor to improve production efficiency. At present, the average coating speed of the papermaking reconstituted tobacco industry is about 120m / min, and the corresponding average coating rate is 36%-38%. However, increasing the coating speed will inevitably reduce the contact time between the blank substrate and the coating liquid, and the coating rate will be correspondingly reduced under the premise that the penetration rate of the coating liquid on the substrate remains unchanged. In addition, after the coating speed is increased, since the penetration rate of the coating liquid remains unchanged, part of the coating liquid will remain on the surface ...
