Problems solved by technology

[0008] 1. The raw materials of tobacco leaves are tense;
[0009] 2. The extraction rate of raw materials is not high, the pressure of sewage discharge is high, and the raw materials of tobacco leaves are not fully utilized
[0010] Product quality, especially the sensory quality, still has certain defects: exogenous chemical smell and miscellaneous gas, strong irritation, heavy oral residue

Embodiment 1

[0022] Example 1: Add 4L of water to 1000g of tobacco leaf powder, stir evenly at 30°C, adjust the ultrasonic power to 500w, extract for 0.5 hours, and then press and filter to separate the separated aqueous solution at 50°C, - Vacuum concentration under the condition of 0.09MPa to obtain a concentrated solution, the mass percentage of solids in the concentrated solution reaches 30%;

[0023] After defibrating and beating the solid raw material residue obtained by pressing and separating, the paper base of reconstituted tobacco leaves is made by papermaking method; the concentrated solution is dip-coated on the paper base, and after rapid drying at 100°C, the papermaking process reconstituted tobacco leaves are adjusted. Moisture content to 12%;

[0024] The miscellaneous gas and irritation of the prepared paper-making reconstituted tobacco leaves are reduced, the oral cavity residue is reduced, and the taste quality is improved

Embodiment 2

[0025] Example 2: Add 12L of tobacco into 1000g of tobacco leaf powder and tobacco stem 1:1 mixture, extract 2000w ultrasonically at 80°C for 2 hours, and after separation by centrifugal filtration, vacuum concentrate at 100°C and 0MPa Obtain a concentrated solution; the mass percentage of solids in the concentrated solution reaches 50%;

[0026] After the solid raw material residue obtained by centrifugation is defibrated and beaten, it is made into a paper-making reconstituted tobacco paper base by the papermaking method; Method reconstituted tobacco leaf moisture content to 12%;

[0027] The miscellaneous gas of the reconstituted tobacco leaves by the papermaking method is weakened, the mouth residue is weakened, the aftertaste is obviously pure, and the taste quality is significantly improved.

Embodiment 3

[0028] Example 3: Add 7L of water to 1000g of tobacco stems, stir and ultrasonically extract at 55°C for 1.5 hours, press and filter and separate, then vacuum concentrate at 80°C and -0.09MPa to obtain a concentrate; The mass percentage of medium solids reaches 40%;

[0029] The solid raw material residue obtained by pressing and separating is defibrated and beaten, and then made into a paper base for reconstituted tobacco leaves by a papermaking method. The concentrated solution is dip-coated on the paper base of the reconstituted tobacco leaves by the papermaking method, and after being quickly dried at 140° C., the water content of the reconstituted tobacco leaves by the papermaking method is adjusted to 12%.

[0030] The smoke of the reconstituted tobacco leaf by the papermaking method has a slight stalk, but no residue, the aftertaste is obviously pure, and the smoking comfort and taste quality are improved.

Abstract

The invention discloses a raw material extracting method for paper-making-method remade tobaccos. The raw materials extracting method includes steps of adding extracting solvent and tobacco raw materials into an extracting tank to obtain extracts; combining one or two of tobacco shreds and stems in an optional proportion to form the raw materials; obtaining tobacco water solution by means of squeezing, filtering and separating the extracts; concentrating the tobacco water solution in a vacuum manner; coating concentration liquid onto a paper base; and drying the paper base coated with the concentration liquid, so that the paper-making-method remade tobaccos are obtained. The raw material extracting method is simple in process and high in controllability, can be widely applied to producing the paper-making-method remade tobaccos, and offensive and irritancy of the remade tobaccos can be reduced.

Description

Technical field: [0001] The invention relates to a method for extracting raw materials of reconstituted tobacco leaves by a papermaking method. Background technique: [0002] Compared with the reconstituted tobacco leaves produced by the roll pressing method and the thick pulp method in my country, the reconstituted tobacco leaves of the papermaking method have unique advantages, including: [0003] 1. Low density and high filling value; [0004] 2. Good mechanical processing resistance and high silk forming rate; [0005] 3. The burning speed is fast and the tar release is low, which is one of the effective means to reduce the tar in cigarettes; [0006] 4. The product has plasticity, and the physical properties and internal chemical indicators of papermaking reconstituted tobacco can be manually adjusted according to actual needs, so as to effectively improve the internal quality of cigarettes. [0007] At present, there are still some links to be further improved in th...
