Embodiment 1

[0013] Example 1: Weigh 4g of shredded tobacco and put it into a tube furnace, heat it to 200°C, pass nitrogen gas, bring the smoke generated by pyrolysis into an absorption bottle placed in a cold trap, absorb it with 25mL propylene glycol, and use 40mL Propylene glycol washes out the smoke condensate in the pipe to obtain tobacco extract.

Embodiment 2

[0014] Example 2: Weigh 4g shredded tobacco and put it into a tube furnace, heat it to 400°C, pass nitrogen gas, bring the smoke generated by pyrolysis into an absorption bottle placed in a cold trap, absorb it with 25mL propylene glycol, and use 40mL Propylene glycol washes out the smoke condensate in the pipe to obtain tobacco extract.

Embodiment 3

[0015] Example 3: Weigh 4g of shredded tobacco and put it into a tube furnace, heat it to 600°C, pass nitrogen gas, bring the smoke generated by pyrolysis into an absorption bottle placed in a cold trap, absorb it with 25mL propylene glycol, and use 40mL Propylene glycol washes out the smoke condensate in the pipe to obtain tobacco extract.

Abstract

The invention relates to electronic cigarettes, in particular to a method for applying tobacco subjected to dry distillation pyrolysis to a novel tobacco product to obtain an extract with sensual pleasures and psychological intensity similar to those of traditional cigarettes. The method for preparing electronic cigarette nicotine liquid by means of tobacco subjected to dry distillation pyrolysis comprises the steps of weighing tobacco, placing tobacco in a heating furnace, increasing temperature to 150-1000 DEG C, introducing carrier gas, introducing smoke generated from pyrolysis into an absorption bottle, placing the absorption bottle in a cold trap, conducting smoke collection with an electronic cigarette solvent, washing smoke condensation products in a pipeline out by means of collection liquid, and obtaining smoke extraction solution. The electronic cigarette nicotine liquid has the advantage that sensual pleasures and psychological intensity similar to those of traditional cigarettes are obtained.

Description

technical field [0001] The present invention relates to electronic cigarettes, and in particular to a tobacco treatment method for treating tobacco by dry distillation and pyrolysis and applying it to new tobacco products, so as to obtain extracts close to the sensory enjoyment and physiological strength of traditional cigarettes. Background technique [0002] Smoking is harmful to health, and second-hand smoke is even more harmful, causing secondary pollution and public hazards. Therefore, smokeless tobacco products are in urgent need of research and development. New tobacco products such as electronic cigarettes, heat-not-burn tobacco products, and snus have become hot spots in domestic and foreign industries. . Tobacco combustion process has complex thermal cracking, Maillard and other reactions, and different temperatures and atmospheres have a great impact on the product. Studies have shown that tobacco releases the most types of aroma components when heated to 600°C. ...
