Description

dry distillation cigarette

The invention belongs to the field of cigarettes, and in particular relates to dry distillation cigarettes.

Background technique

Studies have shown that nicotine and most tobacco flavor components can be transferred to smoke at lower temperatures (300-500°C). If the temperature of the cigarette is lowered to below 600°C (the ignition point of tobacco is about 700°C), various harmful components of the smoke can be greatly reduced, while the aroma components are relatively less affected. Therefore, a kind of cigarette that utilizes carbonaceous heat source to carry out dry distillation tobacco component is invented.

Retort cigarettes are mainly composed of four parts, namely heat source section, dry distillation section, filling section and stick section. The heat source section is based on carbon rods, and the outer layer is wrapped with a breathable layer and ordinary cigarette paper in turn; the dry distillation section is divided into three layers from the inside to the outside, the first layer is dry distillation shredded tobacco, the second layer is heat-conducting insulation layer, and the third layer is It is a flame-retardant wrapping layer, and the second and third layers are aluminum foil paper; the filling section mainly serves two functions, one is to supplement the supply of atomized raw materials, and the other is to reduce the temperature of the smoke after carbonization and atomization to prevent burns. Consists in part of tobacco products and the airtight rolling papers that wrap tobacco products.

R.J. Reynolds Tobacco’s cigarette carbon heat source adopts the method of wrapping carbon rods with glass fibers. However, the carbon rods are formed by extrusion, and the interior is dense. In order to form hot air flow, the outer layer needs to be wrapped with breathable glass fibers. Some studies believe that, Even if such particles can be trapped by the filter material, they will inevitably be adsorbed on the filter during packaging and other processes, resulting in inhalation and endangering health. At the same time, dense carbon rods are also more difficult to ignite than slender carbon filamentous materials.

Contents of the invention

The object of the present invention is to address the above-mentioned shortcomings and provide a retort cigarette with a carbonaceous heat source with natural voids, thereby reducing the harm caused by glass fiber inhalation into the human body and improving the flammability of the carbonaceous heat source.

The above-mentioned purpose is achieved through the following technical solutions:

A dry distillation type cigarette, comprising a heat source section, a dry distillation section, a filling section and a stick section, the heat source section, a dry distillation section, a filling section and a stick section connected in sequence, the heat source section includes a carbonaceous heat source and a carbonaceous heat source wrapped in a carbonaceous Cigarette paper on the outer layer of the heat source, the interior of the carbonaceous heat source is provided with pores penetrating in the axial direction.

There is also a metal layer between the carbon heat source and the cigarette paper, and the metal layer is provided with mesh pores.

Preferably, the metal is aluminum foil.

As a preferred solution, the carbon heat source is a multi-layer structure rolled from sheet-like carbonaceous materials, and the pores are arranged between the sheet-like carbonaceous materials.

As another preferred solution, the carbon heat source is a porous structure rolled from filamentous carbonaceous materials, and the pores are arranged between the filamentous carbonaceous materials.

The filamentous carbonaceous material is distributed along the axial direction of the cigarette.

The mesh pores cannot pass a ball with a diameter of 3 mm.

The suction resistance of the heat source section is 10-40Pa/mm.

The beneficial effects of the present invention are:

1) The heat source section in the present invention has natural gaps, is elastic, and is convenient for coiling processing, while the carbon rod in the existing heat source section is formed by extrusion, and the inside is dense. In order to form air permeability and coiling flexibility, the outer surface The air-permeable glass fiber layer should be wrapped, but the carbon heat source in the present invention is not wrapped with glass fiber, thereby reducing the harm caused by glass fiber inhalation into the human body.

2) Since the heat source section in the present invention is provided with an axially penetrating gap, there is a better air flow through the channel, so the flammability of the heat source section of the present invention is better than that of the heat source section made of the same material. The atomization effect is also better.

3) The present invention has simple structure, convenient manufacture and low production cost.
