Embodiment 1

[0023] A method for preparing shredded tobacco for smoking at low temperature without combustion, comprising the following steps:

[0024] (1) Take 50 kg of tobacco leaf fragments, use a stainless steel extraction tank, add 8 times the weight of tobacco leaf fragments in hot water at 60°C, stir and soak for 15 minutes;

[0025] (2) crushing the soaked tobacco leaf fragments with a disc mill until the diameter of the fragments is less than 1mm, forming a slurry;

[0026] (3) Continuously pump the slurry to the rotating cone distillation tower for steam distillation, separate and obtain the solid slurry, and condense and recover the volatile aroma components at the same time, control the distillation temperature in the tower to 80°C, and the vacuum degree to 0.08MPa;

[0027] (4) Concentrate the aroma component solution after separation and recovery to a mass concentration of 50% with a low-temperature flash evaporation device, and control the concentration temperature to 50°C; ...

Embodiment 2

[0036] A method for preparing shredded tobacco for smoking at low temperature without combustion, comprising the following steps:

[0037] (1) Take 200 kg of tobacco leaf fragments, use a stainless steel extraction tank, add 10 times the weight of tobacco leaf fragments in hot water at 50°C, stir and soak for 20 minutes;

[0038] (2) crushing the soaked tobacco leaf fragments with a disc mill until the diameter of the fragments is less than 1mm, forming a slurry;

[0039] (3) Continuously pump the slurry to the rotating cone distillation tower for steam distillation, separate and obtain the solid slurry, and condense and recover the volatile aroma components at the same time, control the distillation temperature in the tower to 100°C, and the vacuum degree to 0.04MPa;

[0040] (4) Concentrate the aroma component solution after separation and recovery to a mass concentration of 60% with a low-temperature flash evaporation device, and control the concentration temperature to 60°...

Embodiment 3

[0049] A method for preparing shredded tobacco for smoking at low temperature without combustion, comprising the following steps:

[0050] (1) Take 100 kg of tobacco leaf fragments, use a stainless steel extraction tank, add 12 times the weight of tobacco leaf fragments in hot water at 40°C, stir and soak for 30 minutes;

[0051] (2) crushing the soaked tobacco leaf fragments with a disc mill until the diameter of the fragments is less than 1mm, forming a slurry;

[0052] (3) Continuously pump the slurry to the rotating cone distillation tower for steam distillation, separate and obtain the solid slurry, and condense and recover the volatile aroma components at the same time, control the distillation temperature in the tower to 90°C, and the vacuum degree to 0.06MPa;

[0053] (4) Concentrate the aroma component solution after separation and recovery to a mass concentration of 55% with a low-temperature flash evaporation device, and control the concentration temperature to 55°C...

Abstract

The invention discloses a preparation method of non-burning low-temperature smoking tobacco shreds. The preparation method comprises the following steps: soaking, pulping and distilling tobacco leaf fragments; recycling and concentrating distilled fragrance to prepare incense liquid; diluting distilled solid slurry, and shaping and drying the distilled solid slurry to obtain tobacco flakes; after slicing and shredding the tobacco flakes, drying tobacco shreds; applying the incense liquid to the tobacco shreds, and storing and alcoholizing the tobacco shreds to obtain the low-temperature smoking tobacco shreds. The tobacco shreds prepared by the preparation method can enrich a large quantity of endogenous low-temperature volatile incense-making components of tobacco leaves; under a non-burning low-temperature heating condition, a large quantity of tobacco smell can be generated; and the tobacco smell has relatively high similarity to the conventional tobacco smoke, so that sense requirements of a smoker can be met better.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of non-burning low-temperature tobacco. Background technique [0002] Tobacco industry enterprises are faced with the contradiction of not only paying attention to consumers' health, reducing the release of harmful substances in cigarettes, but also improving economic benefits. Therefore, the development of new non-combustible tobacco has become a new topic and a key research and development direction of the tobacco industry. Non-combustible low-temperature smoking tobacco is a new type of tobacco product that is different from traditional cigarettes. It mainly relies on heat sources to heat and bake shredded tobacco at a lower temperature, and the volatile components in shredded tobacco volatilize to form smoke. In order to realize the delivery of smoke to the respiratory system under non-combustion conditions during the suction process. At present, most low-temperature tobacco smoke...
