Problems solved by technology

[0004] However, the dry distillation spices extracted in the prior art all use tobacco leaves, shredded tobacco or tobacco powder as raw materials, have a low bulk density, and have the problem of a small amount of feeding at one time. The aroma components are condensed into the dry distillation product, which is unfavorable to the quality of the heat-reactive flavor and the cleaning of the extraction tank, and the yield of the prepared flavor is low, making it difficult to realize industrialized mass production
At the same time, the product has not been effectively refined in the prior art, and there is a problem that the core fragrance component groups are not concentrated
Moreover, the corresponding dry distillation extraction device is not perfect, and there are defects such as complex operation process, inability to meet continuous production requirements, insufficient extraction leading to low yield of spices, etc.

Embodiment 1

[0039] see Figure 1 ~ Figure 3 , this embodiment discloses a mass-preparation device for tobacco thermal reaction spices, including an extraction tank 1, a first condenser 2, a first liquid storage tank 3, a concentration tank 4, and a second condenser 5 connected in sequence through pipelines , the second liquid storage tank 6, the vacuum pump 7. The periphery of the tank body of the extraction tank 1 is wrapped with a heating jacket 8, and the inner cavity of the heating jacket 8 forms a heating chamber. Circulating hot oil is filled into the heating chamber of the heating jacket 8, and the extraction tank 1 is heated more evenly by means of peripheral circulating hot oil heating. The heating jacket 8 outside the extraction tank 1 is also wrapped with a layer of insulation cover 9 to prevent heat loss caused by the distribution of heat from the hot oil. The top of the tank body of the extraction tank 1 is provided with a tank cover 10, and the top of the tank cover 10 of ...

Embodiment 2

[0047] The preparation method of the present embodiment tobacco thermal reaction spices is as follows:

[0048] Mix 30kg of Zimbabwe flue-cured tobacco powder, 10kg of Hunan flue-cured tobacco powder and 10kg of flue-cured tobacco stem powder, use 10kg of water, 10kg of ethanol as wetting agent, 1kg of sodium alginate and 0.5kg of chitosan as binder, and use extrusion-spheronization The granulation method was carried out, dried at 80°C for 1 hour, and the tobacco particles of 10 to 40 meshes were screened out by a sieving machine.

[0049] Using the device and operation method shown in Example 1, the tobacco particles were dry-distilled and extracted at 240°C for 2 hours under the protection of nitrogen, and the obtained extract was concentrated by vacuum distillation at 55°C and 0.7MPa for 3 hours, thereby obtaining tobacco heat-reactive spice A, which The main chemical components are shown in Table 1.

Embodiment 3

[0052] In this embodiment, 20kg Guizhou flue-cured tobacco powder, 25kg Hunan flue-cured tobacco powder and 5kg Burley tobacco powder are mixed, 11kg water, 9kg ethanol are used as wetting agent, 0.5kg carboxymethyl cellulose sodium and 0.5kg chitosan are mixed as binding agent The agent was centrifugally granulated, dried at 80°C for 1 hour, and granules of 20-50 mesh were screened out by a sieving machine.

[0053] Using the device and operation method shown in Example 1, the tobacco particles were dry-distilled and extracted at 150°C for 3.5 hours under the protection of nitrogen, and the obtained extract was concentrated by vacuum distillation at 50°C and 0.8MPa for 3.5 hours, thereby obtaining tobacco thermal reaction flavor B .

[0054] Add the obtained tobacco thermal reaction fragrance B from the feed port of the rectifier, and carry out rectification at a temperature of 95°C, a vacuum of 0.05MPa, and a reflux ratio of 2:1. After completion, collect the light component...

Abstract

The invention discloses a macro preparation method of tobacco thermal reaction spice. The macro preparation method comprises two procedures of extraction and concentration, and comprises the followingsteps: granulating tobacco powder serving as a raw material to obtain tobacco particles, performing destructive distillation extraction on the tobacco particles under the protection of nitrogen, andperforming reduced pressure distillation and concentration on the obtained extract to obtain the tobacco thermal reaction spice. The adopted tobacco particles are large in stacking density, the reaction feeding amount is large, and the yield of the extracted thermal reaction spice is high.

Description

technical field [0001] The invention belongs to the technical field of novel tobacco products, and relates to a method for preparing a tobacco heat-reactive fragrance in large quantities. Background technique [0002] Both electronic cigarettes and heated cigarettes belong to the category of new tobacco products. The working principle of e-cigarettes is to heat glycerin, propylene glycol-based e-liquid containing nicotine (salt) and flavors and fragrances through an atomizer to produce aerosols. Commercially available tobacco-flavored e-cigarettes generally use monomer spices to imitate tobacco flavors. , making the expression of tobacco taste extremely unnatural. The tobacco material in the heated cigarette is in a non-combustible state during the heating process and has gone through three stages of "drying-volatilization-curing", which can reduce the harmful substances produced by the high-temperature combustion and cracking of tobacco. Due to the lower heating temperatur...
