Problems solved by technology

In the heating effect evaluation and sensory evaluation of traditional cigarettes, it is found that the smoke concentration of conventional cigarettes is very small in the heat-not-burn state, and the cigarette paper has obvious water stains. The sensory evaluation shows that the suction end of the filter is The smoke is too hot

Abstract

The invention provides a supercritical extraction treatment method of cut tobacco applicable to a heating non-combustion state. The method comprises the following steps of (1) taking tobacco raw materials for use; (2) putting the tobacco raw materials into a supercritical extraction device; and relieving the pressure at certain extraction pressure and temperature after the extraction time is reached so that all extracts cover the surface of the cut tobacco; (3) putting the tobacco obtained after the treatment in the step (2) into the supercritical extraction device; adding a certain number ofentrainers at the certain extraction pressure and temperature; after the extraction time is reached, taking out extracts by a separation kettle; and obtaining extracted cut tobacco by an extraction kettle; and (4) uniformly mixing the cut tobacco obtained in the step (3) with a humectant; 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 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 released from the m...
