Problems solved by technology

[0004] The above technologies mostly use multi-stage pressurized or decompressed extraction, which requires high production equipment and large investment, and when the extracted organic aroma substances are applied back to the surface of the product, there are odors such as poor taste quality and heavy miscellaneous gas. Defects that affect the use and addition of tobacco sheets in cigarette products

[0019] Propylene glycol is miscible with water, and the mass percentage of propylene glycol in the solution is respectively prepared as 0% to 25% (see Table 2 for details), and sodium bicarbonate (NaHCO 3 ), so that the concentration of sodium bicarbonate is 2%. The extracted liquid obtained and the raw material of the paper-making tobacco sheet were subjected to a single extraction under normal pressure at a mass ratio of 5:1, the extraction temperature was 40-80°C (see Table 2), and the extraction time was 30-90min (see Table 2) . Among them, propylene glycol and disodium bicarbonate are commercially available analytical reagents. The extraction results are shown in Table 2.

[0020] Table 2

[0021] Example

[0022] The results in Table 2 show that the addition of propylene glycol to the extract solution system at 3%-25% can significantly improve the extraction rate of raw materials, but when the concentration is higher than 20%, the extraction rate decreases s...

[0024] Be that the sodium bicarbonate of different amounts is added in the 10% propylene glycol aqueous solution in mass concentration, make the concentration of sodium bicarbonate be 0%-9% (specifically see Table 3), the extraction liquid that obtains is with papermaking method tobacco sheet raw material by mass ratio The ratio of 5:1 is carried out for a single leaching under normal pressure, the extraction temperature is 40-80°C (see Table 3), and the extraction time is 45min, 30-90min (see Table 3). Among them, propylene glycol and disodium bicarbonate are commercially available analytical reagents. The extraction results are shown in Table 3.

[0025] table 3

[0026] Example

[0027] The results in Table 3 show that the concentration of disodium bicarbonate solution in the range of 1%-5% can obviously improve the extraction rate of raw materials.

Abstract

The invention discloses a method for preparing a leaching liquor of paper-making tobacco sheet raw materials. According to the method, propylene glycol and water are mixed and dissolved to obtain a solution, the mass percent of the propylene glycol in the solution is controlled in a range from 3% to 20%, then sodium bicarbonate is added in the solution, and the mass concentration of the sodium bicarbonate in the solution is controlled in a range from 1% to 5% to obtain a normal pressure leaching liquor for the paper-making tobacco sheet raw materials. By means of the leaching liquor prepared by the method, the one-time normal pressure extraction ratio of tobacco powders and tobacco stems can reach to above 65%, the extraction ratio is far higher than the one-time extraction ratio which is about 50% in existing methods in factory, and the extraction effects are extremely remarkable.

Description

technical field [0001] The invention relates to a preparation and extraction method of an extraction liquid extracted from tobacco sheet raw materials by papermaking method under normal pressure. The extraction liquid obtained in the present invention is used for the normal pressure extraction of tobacco sheet raw materials by papermaking method, and the primary extraction of tobacco dust under suitable conditions The yield can reach more than 70%, and the one-time extraction rate of tobacco stem can reach more than 65%. Background technique [0002] Tobacco sheet by papermaking method uses waste tobacco stems, tobacco powder and other raw materials in the cigarette production process. After three steps of leaching and concentration, beating and papermaking, and drying and flavoring, it is made into a sheet with properties close to or even better than natural tobacco leaves. Cigarette production, so that the raw materials of tobacco leaves can be utilized to the maximum exte...
