Method for preparing electronic tobacco juice from tobacco raw material by using alkali type low-temperature dry distillation process

Abstract

The invention relates to the field of electronic smoke, and particularly relates to a tobacco treatment method that tobacco is treated by using an alkali type low-temperature dry distillation process, the treated tobacco is used in a novel tobacco product, and obtained pyrolysate is free of acerbity but sensory feeling approximate to that of conventional cigarette. The method for preparing electronic tobacco juice from a tobacco raw material by using an alkali type low-temperature dry distillation process comprises the following steps: spreading the tobacco raw material in a tray, uniformly spraying an alkali liquid to the surface of the tobacco raw material, transferring the tobacco raw material into a heating kettle of a dry distillation furnace, introducing a carrier gas, performing programmed heating on the dry distillation furnace until the temperature reaches 180-280 DEG C, carrying out pyrolysate from the dry distillation furnace with the carrier gas, and capturing and absorbing the pyrolysate by using an electronic smoke solvent, so as obtain a tobacco raw material dry distillation extract, wherein the mass ratio of the alkali liquid to the tobacco raw material is (1-5):100. The electronic tobacco liquid prepared by using the method has the advantages of fragrance, flavor and physiological satisfaction approximate to those of conventional cigarette, and a mouth has no acerbity.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a technical method for processing tobacco raw materials by an alkaline low-temperature dry distillation method to prepare an extract close to the sensory quality and taste of traditional cigarettes, and applying it to the formulation of electronic cigarette liquid. Background technique [0002] Electronic cigarettes, also known as "atomized electronic cigarettes", usually have a similar appearance to cigarettes, can simulate the smoking of traditional cigarettes, and deliver the liquid into the respiratory system after being atomized by a battery heating device. Compared with traditional cigarettes, e-cigarettes have gradually attracted attention because they do not contain tar, carbon monoxide, and do not produce second-hand smoke. However, commercially available e-cigarette products are all composed of flavors and fragrances, with simple ingredients and a taste th...

Problems solved by technology

[0003] However, further studies have shown that the organic acidic substances contained in tobacco raw materials are extremely volatile during the dry distillation process, resulting in high acidic components in the dry distillation product and a sour taste.

Moreover, in the existing patents, the temperature for dry distillation of tobacco raw materials is relatively high, and most dry distillation products are obtained above 300°C. Although high temperature is more conducive to the volatilization of aroma substances, there is carbonization of tobacco raw materials above 300°C, and dry distillation products will produce Obvious burnt smell, which seriously affects its sensory quality
