Abstract

The invention provides a dynamic extraction treatment method of cut tobacco in a heating non-combustion state. The method concretely comprises the following steps of (1) taking tobacco raw materials for use; (2) putting the tobacco raw materials in the step (1) into a supercritical extraction device; adding a certain number of entrainers at certain extraction pressure and temperature; and after the extraction time is reached, taking out extracts to obtain the extracted cut tobacco (the extraction temperature is 40 to 50 DEG C; the time is 2 to 5h; the extraction pressure is 20 to 30 MPa; the separation pressure is 4 to 8 MPa; the entrainers are selected from 1,2-propanediol, glycerol or a mixture of 1,2-propanediol and glycerol; and the consumption of the entrainers is 5 to 20 percent of the materials); and (3) uniformly mixing the cut tobacco obtained in the step (2) with a moisture preservation agent; and then performing balancing treatment 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 ...
