Problems solved by technology

[0003] The object of the present invention is a method for preparing a concentrated liquid of reconstituted tobacco specially developed for the problems of the existing technology of the above-mentioned prior art, such as the low aroma of reconstituted tobacco and relatively high production costs. Next, the production raw materials are classified according to grades, and ethanol and other organic solvents are selected for leaching of high-grade raw materials, so that more flavor substances can be dissolved in the leaching liquid, so that the reconstituted tobacco leaf products can highlight the original aroma of tobacco. Harmony with Leaf Group Formula in Cigarette Use

Embodiment 1

[0021] Formulate 7 kinds of tobacco stems and 5 kinds of tobacco powder according to a certain ratio, among which 1 kind of tobacco stem with higher grade and 4 kinds of tobacco powder are mixed in a total of 30Kg, and 6 kinds of tobacco stem with lower grade and 1 kind of tobacco powder are mixed Finally, a total of 70Kg was mixed.

[0022] The high-grade raw material is leached with ethanol with a concentration of 15%, the conditions are: temperature 30°C, solid-liquid ratio 1:9 (weight ratio), time 20min, leaching twice. It is stirred by paddle type straight leaf method, squeezed, separated and filtered after leaching.

[0023] Pour the ethanol leaching solution into the concentration tank, the concentration conditions are: temperature 45°C, vacuum degree 0.092MPa, when the Baume number of the concentrated solution reaches 25-35 0 When Be, break the vacuum and add 0.9kg urea and 0.6kg ammonium dihydrogen phosphate, raise the temperature to 70°C and continue to concentrate ...

Embodiment 2

[0029] The 4 kinds of tobacco stems and 6 kinds of tobacco powders are formulated according to a certain ratio, wherein 20Kg of 6 kinds of tobacco powders with higher grades are mixed in total, and 4 kinds of tobacco stems with lower grades are mixed in total of 80Kg.

[0030] The high-grade raw material is leached with ethanol with a concentration of 5%, and the conditions are: temperature 20°C, solid-liquid ratio 1:10 (weight ratio), time 25min, leaching twice. It is stirred by paddle type straight leaf method, squeezed, separated and filtered after leaching.

[0031] Pour the ethanol leaching solution into the concentration tank, the concentration conditions are: temperature 40°C, vacuum degree 0.092MPa, when the Baume number of the concentrated solution reaches 25-35 0 When Be, break the vacuum and add 0.8kg urea and 0.7kg ammonium dihydrogen phosphate, heat up to 80°C and continue to concentrate under normal pressure until the Baume number reaches 38-45 0 Stop concentrat...

Embodiment 3

[0037] Formulate 5 types of tobacco stems and 8 types of tobacco powder according to a certain ratio, in which 2 types of tobacco stems with higher grades and 6 types of tobacco powders are mixed for a total of 35Kg, and 3 types of tobacco stems with lower grades and 2 types of tobacco powders are mixed Finally, a total of 65Kg was mixed.

[0038] The high-grade raw material is leached with 10% ethylene-propanol, the conditions are: temperature 40°C, solid-liquid ratio 1:8 (weight ratio), time 30min, leaching twice. It is stirred by paddle type straight leaf method, squeezed, separated and filtered after leaching.

[0039] Pour the ethylene-propanol leaching solution into the concentration tank. The concentration conditions are: temperature 50°C, vacuum degree 0.090MPa, when the Baume number of the concentrated solution reaches 25-35 0 When Be, break the vacuum and add 1.75kg urea and 1.3kg ammonium dihydrogen phosphate, heat up to 80°C and continue to concentrate under norma...

Abstract

A method for preparing a reconstituted tobacco leaf concentrate, comprising the following steps: a. selecting tobacco raw materials for compatibility according to product target requirements, and classifying and classifying the tobacco raw materials for extraction and concentration respectively; b. using high-grade tobacco raw materials Extract, filter and concentrate the organic solvent with a concentration of 5-50%, add urea and ammonium dihydrogen phosphate during the concentration process, and then concentrate at normal pressure at elevated temperature; c. Extract, filter and concentrate low-grade tobacco raw materials with water , add urea and ammonium dihydrogen phosphate, then increase the temperature and concentrate under normal pressure; d, mix and prepare the two concentrates and then apply them to the film base. The essence of the present invention is: select formula raw material according to target requirement, the raw material of high grade is leached with the organic solvent of low concentration, and the raw material of low grade is leached with water, so that extract more flavor substances from high-grade tobacco raw material, Thereby making the product more prominent the fragrance of tobacco.

Description

technical field [0001] The invention relates to the tobacco industry, in particular to a method for preparing a reconstituted tobacco leaf concentrate, which is used for coating on a reconstituted tobacco leaf base made by a papermaking method. Background technique [0002] Papermaking reconstituted tobacco leaves use waste tobacco stems, tobacco powder and other raw materials in the cigarette manufacturing process, and comprehensively utilize leaching, separation, recombination, papermaking and other technologies to produce sheet-like substances that meet the needs of cigarette formulations and are close to natural tobacco. At present, the most widely used papermaking reconstituted tobacco production technology is a two-step production process. The first step is to separate the soluble chemical components in the tobacco from the insoluble plant fibers. The second step is to separate the plant fibers in the tobacco. The film base is made by papermaking technology and the sol...
