Embodiment 1

[0027] S1. Cleaning the tobacco stems (sourced from Guangdong China Tobacco Raw Materials Bank, which does not limit the present invention, those skilled in the art can use tobacco stems from other sources);

[0028] S2. Using 5 mL of hot water at 60°C to extract 1 g of tobacco stems for 50 min;

[0029] S3. After leaching the tobacco stems, filter to collect the extraction liquid and the extracted tobacco stems respectively; dispose of the extraction liquid separately, squeeze the tobacco stems dry, cut into shreds to obtain cut stems, and dry the cut stems to be evaluated.

[0030] The processes such as pressing stems, squeezing, and drying refer to existing conventional technologies.

[0031] The gap between the rolls of the stalk is set at 0.7-1.0mm, HDT expansion technology is adopted, and the temperature is set at 200°C-220°C.

Embodiment 2

[0033] S1. Clean the tobacco stems;

[0034] S2. Using 20 mL of hot water at 60°C to extract 1 g of tobacco stems for 30 min;

[0035] S3. After leaching, filter to collect the extraction solution and the extracted tobacco stems respectively; the extraction solution is disposed of separately, the tobacco stems are squeezed dry, and shredded to obtain shredded stems, which are to be evaluated after being dried.

[0036] The processes such as pressing stems, squeezing, and drying refer to existing conventional technologies.

[0037] The gap between the rolls of the stalk is set at 0.7-1.0mm, HDT expansion technology is adopted, and the temperature is set at 200°C-220°C.

Embodiment 3

[0039] S1. Clean the tobacco stems;

[0040] S2. Using 80°C hot water 8mL to extract 1g of tobacco stems for 60min;

[0041] S3. After leaching, filter to collect the extraction solution and the extracted tobacco stems respectively; dispose of the extraction solution separately, squeeze the tobacco stems dry, cut into shreds to obtain shredded stems, and dry the shredded stems for use in the cigarette leaf group in the recipe.

[0042] The processes such as pressing stems, squeezing, and drying refer to existing conventional technologies.

[0043] The gap between the rolls of the stalk is set at 0.7-1.0mm, HDT expansion technology is adopted, and the temperature is set at 200°C-220°C.

Abstract

The invention discloses an upgrading method of tobacco stems in tobacco shreds. The method includes: cleaning tobacco stems, extracting with water 50-70 DEG C hot, filtering, and collecting extracted fluid and extracted stems; further disposing the extracted fluid, drying the tobacco stems by squeezing, and cutting to obtain stem shreds; separating, purifying and compressing the extracted fluid, and performing appropriate Maillard reaction on a reaction product to recycle the stem shreds for feeding. The upgrading method of tobacco stems in tobacco shreds has the advantages that the stem shreds processed by the method are added to a cigarette tobacco set, sensor quality is greatly improved, physicochemical indexes are significantly improved, cigarettes with the same tobacco stem processed by the method have comprehensive quality significantly improved, application value of the tobacco stems in cigarettes is improved, and use value and use ratio of raw tobacco stems are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and more specifically relates to a method for improving the quality of tobacco stems mixed in shredded tobacco. Background technique [0002] my country is a big tobacco country, and its annual output and consumption of cigarettes rank first in the world. The huge annual output and consumption of cigarettes puts forward an urgent demand for raw materials for cigarette production. [0003] Tobacco stems are the thick and hard veins of tobacco leaves, accounting for about 25% to 30% of the leaf weight. If the production capacity is 500,000 tons, more than 120,000 tons of tobacco stems are produced every year. As a big tobacco producing country, about hundreds of thousands of tons of tobacco stem waste is discarded and wasted in my country every year. Tobacco stems have been gradually used in cigarette production in recent years, but the tobacco stems are mainly used to prepare recons...
