Problems solved by technology

At present, the research on the theory and method of alcoholization of tobacco leaves is mainly focused on the leaves, while there are few reports on the red alcoholization of tobacco stems during storage, especially the lack of research on the changes of red characteristic chemical indicators in the alcoholization process of tobacco stems, resulting in storage The purpose and time of alcoholization are not clear
Generally, tobacco stems are used in production without effective aging, which will affect the smoking quality of cigarette products

Embodiment 1

[0027] A method for improving the quality of tobacco stems, comprising the steps of:

[0028] 1) Screen the tobacco stems, and remove the broken tobacco stems with a length of less than 10mm and a diameter of less than 1.5mm, and wash the selected tobacco stems in a stem washing machine. The parameters for washing stems are as follows: Tobacco stems The falling water speed is 5m / s, the water temperature is controlled at 35°C, the water speed is 2m / s, the number of filter screens is 25.416 mesh (25.4mm), the screen angle is 30°, the water filtration time is 7s, and the circulating water is replaced every 3 hours. Ozone is passed into the water tank of the stem washing machine to carry out ozone treatment on the tobacco stems after washing for 30 minutes. The ozone is produced by an ozone generator, and the ozone concentration is 350 mg / L. Dry;

[0029] 2) Turn on the far-infrared radiation source, and perform far-infrared radiation treatment on the dried tobacco stems in step ...

Embodiment 2

[0046] The difference between the method of this example and Example 1 is that the parameters for washing the stems in step 1) are: the water temperature of the tobacco stems falls into the water at a speed of 4.6m / s, and the water temperature is controlled at 33°C, and the water speed is 1.5m / s. mm) Filter screen angle 28° Filtration time 7s Replace circulating water every 2h Ozone treatment time is 20min, ozone concentration is 300 mg / L; The intensity of irradiation was 100W, and each irradiation was 10s; the tobacco stems treated with enzymes in step 3) were stored for 2 hours.

Embodiment 3

[0048] The difference between the method of this example and Example 1 is that the parameters for washing the stems in step 1) are: the falling speed of tobacco stems is 4.8m / s, the water temperature is 34°C, the water speed is 2.5m / s, and the water filtration time is 8s; step 2) COSCO The intensity of infrared radiation is 300W, and the tobacco stems are irradiated 4 times, each irradiation is 15s, and the interval of each irradiation is 7.5min; the enzyme solution with a biological enzyme concentration of 0.4mg / mL in step 3), each biological enzyme The dosage is 90U / g, and the detection is carried out after storage. The enzyme-treated tobacco stems are stored for 4 hours.

Abstract

The invention belongs to the field of tobacco processing, and in particular relates to a method for improving the quality of tobacco stems. The method comprises the steps of tobacco stem washing, ozone treatment, far-infrared irradiation, stem storage and the like, during which biological enzyme treatment is combined. By adopting ozone treatment, far-infrared radiation and enzymatic treatment with biological enzymes, this application makes full use of the internal changes of the tobacco stems after ozone, far-infrared radiation, and enzymatic hydrolysis, and better improves the internal quality of the tobacco stems. Specifically, this method can increase the content of total sugar and reducing sugar in tobacco stems, improve the softness of cigarettes, reduce the irritation of cigarettes, and reduce the tar content of smoke, thereby improving the internal quality of tobacco leaves. It has certain advantages in the production of cigarettes. promotion and application value.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for improving the quality of tobacco stems. Background technique [0002] Tobacco stems are an important part of tobacco leaves, and tobacco stems accounting for about 25% of the weight of tobacco leaves can be obtained by separating stem leaves. my country can produce about 600,000 tons of tobacco stems each year, of which about 400,000 tons can be effectively utilized. Cut stems are one of the important components of cigarette formula. Well-processed cut stems have a strong supporting effect, which can improve the combustibility of cigarettes, reduce the consumption of cigarette raw materials, improve the utilization rate of raw materials, and reduce the amount of tar in smoke. Therefore, cut stems Processing technology is very important. The existing cut stem treatment process generally includes feeding, dampening, moistening, storing stems, st...
