Embodiment 1

[0021] Take 500g of a low-grade tobacco leaf formula module tobacco leaf raw material, pack it under the condition of ensuring the appearance, and place it in a closed dry cleaning tank as a whole. After closing the feeding channel, vacuumize, inject liquid propane solvent, and completely immerse the finished tobacco leaf ; The material-solvent ratio is 1:3, the dry cleaning time is 10 minutes, the temperature is 30°C, and the pressure is 0.29MPa; after the dry cleaning, the liquid solvent is pumped into the evaporation tank, and the sample and the liquid solvent are desolvated separately. The solvent gas evaporated from the low-smoke sample and the liquid solvent is compressed and liquefied by the diaphragm compressor, and the liquid solvent flows back to the solvent circulation tank for recycling. After the treatment, the appearance and shape of the tobacco leaves remained good, and the harmful components were all reduced to varying degrees. The ratio of sensory products aft...

Embodiment 2

[0023] Take 200g of blended Henan BK31 low-grade tobacco leaves, pack them under the condition of ensuring the shape, put them in a closed dry-cleaning tank as a whole, inject liquid butane solvent, and completely immerse the finished tobacco leaves; the material-solvent ratio is 1:4, dry-clean The time is 5 minutes, the temperature is 25° C., and the pressure is 0.25 MPa; after the dry cleaning is completed, the solvent is removed according to the method in Example 1, and the sample is taken out. The comparison of sensory products after treatment shows that compared with the control sample, the characteristics of sweetness and aroma are improved, the aroma quality is better, delicate, slightly stronger, less irritating, and the aftertaste is clean and comfortable.

Embodiment 3

[0025] Take 500g of mixed C1B1 low-grade tobacco leaves from the Baiyun warehouse in Guizhou, pack them under the condition of ensuring the shape, place the whole in a closed dry-cleaning tank, inject liquid dimethyl ether solvent, and completely immerse the finished tobacco leaves; the ratio of material to solution is 1: 5. The dry cleaning time is 10 minutes, the temperature is 10° C., and the pressure is 0.36 MPa; after the dry cleaning is completed, the solvent is removed according to the method in Example 1, and the sample is taken out. The ratio of sensory products after treatment shows that compared with the control, the sample has better combustion characteristics, the woodiness and throat dryness are reduced, the richness and fineness are improved, and the aroma volume is increased.

Abstract

The invention discloses a method for improving the use value of inferior tobacco leaves with a subcritical dry cleaning technology, and the method belongs to the field of the tobacco industry. The inferior tobacco leaves are packed and put into a closed dry cleaning tank and vacuumized; an appropriate amount of subcritical fluid is injected into the dry cleaning tank as dry cleaning solvent, and dry cleaning is carried out under a certain dry cleaning condition; after the dry cleaning, the liquid solvent is pumped into an evaporation tank; a sample and the liquid solvent are respectively subjected to desolvation, so that the solvent is separated from the dry cleaned object, and tobacco leaves with higher quality are obtained. The method for improving the use value of the inferior tobacco leaves can effectively improve the quality of the inferior tobacco leaves, has practical value at the aspects of improving the use rate and grade of the inferior tobacco leaves, reducing the cost and the like, and has very wide application prospect.

Description

technical field [0001] The invention relates to a method for dry-cleaning low-grade tobacco leaves by using a subcritical fluid, thereby improving the quality of low-grade tobacco leaf raw materials and increasing their use value. Background technique [0002] Low-grade tobacco leaves refer to tobacco leaves of various grades below the fifth grade of middle yellow, fourth grade of upper yellow, and second grade of green yellow in GB2635-86. In terms of the appearance quality of this part of tobacco leaves, the color is brownish-yellow, yellowish-brown with cyan, uneven thickness, loose leaf structure, weak gloss, with obvious flower pieces, large damage area and insufficient oil content, etc. ; From the perspective of internal smoking quality, the aroma is lacking, the aroma is rough, bitter and spicy, the irritating and astringent taste is obvious, the aftertaste is not clean, and there are many residues in the mouth and tongue. Among them, miscellaneous gases are the main...
