Embodiment 1

[0025] Spray the 40% ethanol solution onto the tobacco leaves using a throat sprayer with compressed air, turning the tobacco leaves during the spraying process to make the spray even. The water content of the sprayed sample is about 19%. The sample is put into a capsule, vacuumed to a relative vacuum of -0.085, and sealed. For capsule high-pressure treatment, apply a pressure of 580MPa and keep it for 5min. Take out the sample and dry it. Cut tobacco shreds to make single tobacco, and place it in a constant temperature and humidity environment with a temperature of 22±2°C and a humidity of 60%±5% for 48 hours.

Embodiment 2

[0027] Spray the 45% ethanol solution onto the tobacco leaves using a throat sprayer with compressed air, turning the tobacco leaves during the spraying process to make the spray even. The water content of the sprayed sample is about 17%. The sample is put into a capsule, vacuumed to a relative vacuum of -0.09, and sealed. For the high pressure treatment of the capsule, apply a pressure of 530MPa and keep it for 10min. Take out the sample and dry it. Cut tobacco shreds to make single tobacco, and place it in a constant temperature and humidity environment with a temperature of 22±2°C and a humidity of 60%±5% for 48 hours.

Embodiment 3

[0029] The 42.5% ethanol solution was sprayed onto the tobacco leaves using a throat sprayer of compressed air, and the tobacco leaves were turned over during the spraying process to make the spray even. The water content of the sprayed sample is about 18%. The sample is put into a capsule, vacuumed to a relative vacuum of -0.095, and sealed. For the high pressure treatment of the capsule, apply a pressure of 550MPa and keep it for 7.5min. Take out the sample and dry it. Cut tobacco shreds to make single tobacco, and place it in a constant temperature and humidity environment with a temperature of 22±2°C and a humidity of 60%±5% for 48 hours.

Abstract

The invention discloses a method for improving the quality of low-grade tobacco leaves. The method includes the following steps of firstly, adding ethanol water to the surfaces of the low-grade tobacco leaves; secondly, sealing and packaging the low-grade tobacco leaves processed in the first step in capsules in a vacuum mode; thirdly, putting the low-grade tobacco leaves packaged in the capsules in the second step in a high-pressure device, and relieving pressure after high-pressure treatment. After the low-grade tobacco leaves are processed through the method, offensive odor of samples is lowered, stimulation is weakened, sensory quality is improved, and meanwhile combustion performance is improved.

Description

technical field [0001] The patent of the invention relates to a synergistic means for improving the quality of low-grade tobacco leaves, which belongs to the field of tobacco production and processing. Background technique [0002] Tobacco leaves are affected by various factors such as soil, climate, variety, cultivation, growing parts, and processing, resulting in differences in quality. Classifying tobacco leaves is conducive to promoting the development of tobacco leaf production and meeting the needs of the cigarette industry. Generally speaking, there are many problems in the use of low-grade tobacco leaves, such as high irritation, poor combustibility, low smoke concentration, flat aroma, insufficient aroma and so on. These problems have caused low-grade tobacco leaves to be sold at extremely low prices for the production of low-grade cigarettes, and even can only be stocked or discarded, resulting in considerable economic losses. In order to improve the quality of lo...
