Abstract

The invention provides a dynamic extraction treatment method suitable for shredded tobacco in a heat-not-burn state, which specifically includes the following steps: 1). Taking tobacco raw materials for use; 2). Putting the tobacco raw materials in step 1) in a supercritical extraction device , under a certain extraction pressure and temperature, add a certain amount of entraining agent, after reaching the extraction time, take out the extract to obtain extracted shredded tobacco; the extraction temperature is 40-50°C, and the time is 2-5h; The extraction pressure is 20-30MPa, and the separation pressure is 4-8MPa; the entrainer is selected from 1,2-propylene glycol, glycerol or a mixture of the two, and the amount is 5-20% of the material; 3) . After uniformly mixing the shredded tobacco obtained in step 2) with the humectant, balance it for a period of time.

Description

technical field [0001] The invention relates to the field of novel tobacco products, in particular to a dynamic extraction treatment method suitable for shredded tobacco in a heat-not-burn state. Background technique [0002] The research and development of new tobacco products is one of the latest major projects determined by the National Bureau. At present, representative heat-not-burn products in the international market are divided into electric heating and carbon heating products, which are characterized by not directly burning cigarettes but through Heating the tobacco material releases smoke, which reduces the harmful components produced by the pyrolysis of tobacco due to high-temperature combustion, and reduces the harmful components of mainstream smoke. Among them, the research on the matrix in the heating section, one of the key technologies of new tobacco products, is particularly important. It mainly focuses on solving the problem that the tobacco extract can be ...
