Embodiment 1

[0029] (1) Take 30 g of untreated traditional shredded tobacco with a moisture content of 12%, then add 4.5 g of propylene glycol and glycerin mixture, mix well and set aside;

[0030] (2) placing the mixture in (1) in an environment with a temperature of 20° C. and a relative humidity of 60% for 48 hours to obtain a traditional shredded tobacco raw material suitable for heating without burning;

[0031] (3) Roll the balanced shredded tobacco into a traditional cigarette, and place it in a heat-not-burn appliance for evaluation;

[0032] (4) The smoking evaluation results show that the smoke concentration of traditional shredded tobacco is small, the smoke is too hot, and the cigarette paper has obvious water stains in the heat-not-burn state. The basic conditions for evaluating the sensory quality are not met.

Embodiment 2

[0034] (1) Supercritical extraction treatment: The traditional shredded tobacco with a moisture content of 12% is subjected to supercritical extraction. The extraction temperature is 50°C and the extraction pressure is 35MPa. The inlet and outlet of the extraction kettle are closed, and the extraction is left to stand for 3 hours. Press to make all the extracts cover the surface of the shredded tobacco, take it out and set aside;

[0035] (2) Place the shredded tobacco in (1) in a supercritical extraction device, add 5% 1,2-propanediol entrainer at an extraction temperature of 50°C and an extraction pressure of 25 MPa, extract for 2 hours, and take out the extract , the shredded tobacco obtained after extraction has a water content of 3%, which is taken out and used for later use;

[0036] (3) Get 30 g of shredded tobacco that contains a certain amount of moisture after being treated in (2), add 4.0 g of propylene glycol and glycerin mixture, and immediately place it at 20 ° C...

Embodiment 3

[0040](1) Supercritical extraction treatment: The traditional shredded tobacco with a moisture content of 12% is subjected to supercritical extraction. The extraction temperature is 50°C and the extraction pressure is 30MPa. The inlet and outlet of the extraction kettle are closed, and the extraction is left to stand for 3 hours. Press to make all the extracts cover the surface of the shredded tobacco, take it out and set aside;

[0041] (2) Put the shredded tobacco in (1) in a supercritical extraction device, add 10% 1,2-propanediol entrainer at an extraction temperature of 50°C and an extraction pressure of 30 MPa, extract for 3 hours, and take out the extract , the shredded tobacco obtained after extraction has a water content of 1%, which is taken out and used for later use;

[0042] (3) Get 30 g of shredded tobacco containing a certain amount of moisture after being treated in (2), then add 4.5 g of propylene glycol and glycerin mixture, and immediately place it at a temp...

Abstract

The invention provides a supercritical extraction treatment method of cut tobacco in 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 an supercritical extraction device; and relieving pressure at certain extraction pressure and temperature after the extraction time is reached so that allextracts cover the surfaces of cut tobacco; (3) putting tobacco obtained in the step (2) into the supercritical extraction device; adding a certain number of entrainers at certain extraction pressureand temperature; after the extraction time is reached, taking out extracts by using a separation kettle; and obtaining the extracted cut tobacco by an extraction kettle; and (4) uniformly mixing thecut tobacco obtained in the step (3) 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 supercritical 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 c...
