Embodiment 1

[0049] Such as figure 1 shown.

[0050] A kind of manufacture method of pollution-free low-tar cigarette, comprises steps as follows:

[0051] (1) Tobacco leaf pretreatment:

[0052] According to the prior art, the tobacco leaves are classified, stemmed, shredded, baked, aired and sun-dried;

[0053] (2) Dry distillation:

[0054] Carry out dry distillation on the tobacco leaves processed in step (1) by dry distillation technology: the dry distillation temperature is 900°C, and the dry distillation pressure is 0.1Mpa;

[0055] (3) Dust removal and purification:

[0056] Removing fine tobacco leaf particles, carbon monoxide, nitrogen oxides and formaldehyde during the dry distillation of tobacco leaves; the fine tobacco leaf particles are particles with a particle size ≧20 μm;

[0057] (4) Frozen collection:

[0058] cooling and collecting the product of dry distillation of tobacco leaves in step (3) with a cooling medium at a temperature of -30 to 0° C., to obtain a dry ...

Embodiment 2

[0066] A manufacturing method of a pollution-free low-tar cigarette as described in Example 1, the difference is that the dry distillation temperature is 600°C.

[0067] The heating carrier is a chemical heating carrier; when smoking, the chemical heating carrier atomizes the smoke essence through chemical heating to achieve the effect of smoking.

Embodiment 3

[0069] A manufacturing method of a pollution-free low-tar cigarette as described in Example 1, the difference is that the inert carrier is a non-heating carrier. The non-heating carrier is wood cellulose, cellulose acetate or propylene fiber, and the non-heating carrier is filled with tobacco essence. When smoking, the airflow enters to promote the volatilization of the tobacco essence in the non-heating carrier to achieve the effect of smoking.

Abstract

The invention relates to a pollution-free low-tar cigarette and a manufacturing method thereof. The manufacturing method comprises the following steps of pre-processing tobacco leaves, distilling in a dry mode, removing dust, purifying, refrigerating, collecting, distilling in a fractional mode, upgrading, combining tobacco extract with inertia carriers, processing and assembling the tobacco extract and the inertia carriers into a cigarette holder, and preparing the pollution-free low-tar cigarette. The manufacturing method has the advantages that the requirement for raw materials is simple, and the tobacco leaves of the same grade or class can be used and do not need to be refined. Moreover, the raw materials are treated simply and the problems of the three wastes are not caused. According to the cigarette, harm of passive smoking to other people and environment in the smoking process is small, the open fire of smoking can be avoided, and fire risks can be reduced.

Description

technical field [0001] The invention relates to a pollution-free low-tar cigarette and a manufacturing method thereof, belonging to the technical field of tobacco manufacturing. technical background [0002] At present, the process of making tobacco leaves into cigarettes includes two major processes: shredded and cigarette rolling, tipping, and packaging. Shredded is the key to the entire process, which also includes tobacco leaf blending, deformation processing (stemming and shredding) ), adding moisture and drying, adding spices and other processes. Qualified cigarettes can only be processed after these processes. In order to improve the aroma quality and certain physical properties of cigarettes, various additives are added to the tobacco leaves. The smoke produced when cigarettes are lit and the gas exhaled by smokers (commonly known as second-hand smoke) contain hundreds of known toxic or carcinogenic substances. General air purification or ventilation equipment cann...
