Method for utilizing acids to prepare piece-shaped carbonaceous heat source material for cigarettes

Abstract

The invention discloses a method for utilizing acids to prepare a piece-shaped carbonaceous heat source material for cigarettes. The method comprises the steps of mixing sodium alginate or ammonium alginate or potassium alginate with carbon powder and water, forming jelly by mixing, enabling mass ratio between sodium alginate or ammonium alginate or potassium alginate and the carbon powder to be 1:(5-45), then extruding the jelly into slices, enabling the slices to be fully contacted with acid solution with a PH value no smaller than 3, and obtaining solidified objects; enabling the solidified objects to undergo rinsing and drying to enable moisture content to reach 10-20%, and obtaining the piece-shaped carbonaceous heat source material for the cigarettes. According to the method, not only is harm caused by a glass fiber inhaled into the human body reduced, but also ignition of a carbonaceous heat source is improved, and the method has the advantages of being simple, short in production cycle and low in cost and the like.

Description

technical field [0001] The invention belongs to the field of cigarettes, and in particular relates to a method for preparing sheet-shaped carbonaceous heat source materials for cigarettes used in low-temperature cigarettes by using acid. Background technique [0002] 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 cigarette that uses a carbonaceous heat source for dry distillation of tobacco components was invented. Among them, the carbonaceous heat source of R.J. Reynolds Tobacco’s Eclipse cigarette uses glass fiber wrapped carbon rods. However, the carbon rods are formed by extrusion. , the interior is dense, and in order to form hot air flow, the out...

Therefore, a cigarette that uses a carbonaceous heat source for dry distillation of tobacco components was invented. Among them, the carbonaceous heat source of R.J. Reynolds Tobacco’s Eclipse cigarette uses glass fiber wrapped carbon rods. However, the carbon rods are formed by extrusion. , the interior is dense, and in order to form hot air flow, the outer layer needs to be wrapped with breathable glass fiber. 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 harm. Healthy, dense carbon rods are also harder to ignite than thinner carbon filaments
