Lemon grass porous particle and application thereof to cigarettes
The invention discloses a lemon grass porous particle and application thereof to cigarettes. The lemon grass porous particle adopts lemon grass powder with the water content being 7 to 9 percent and the particle diameter being 100 to 160 meshes and micro-powder silica gel as raw materials, and adopts one kind or several kinds of materials from sodium carboxymethyl starch and sodium carboxymethyl starch as bonding agents, a fluidized bed top spraying process is adopted for preparation, and 20 to 60 meshes of lemon grass porous particles are obtained. The particle has the advantages that the surface is rough, the specific surface area is higher, the effective contact area of the particle materials and the smoke gas of the cigarettes can be obviously increased, and crotonaldehyde and ammonia in the smoke gas of the cigarettes can be selectively adsorbed. The particle can effectively reduce the irritation of the smoke gas of the cigarettes and improve the aftertaste, and meanwhile, the effect of enhancing the ventilation effect of the smoke gas is also realized. The lemon grass porous particle provided by the invention has the advantages that the production process is simple, the operability and the standardability are high, the raw materials can be easily obtained, the cost is low, the industrial production can be conveniently realized, and good application prospects are realized. 1. A lemon grass porous particles, prepared by the method through the following steps: (1) the temperature of the fresh lemon grass in the 20-25 [...] , humidity 30%-40% moisture to the lower adjusting conditions 7-9%, further crushing into 100-160 purpose powder, spare; (2) in accordance with the weight the share name takes 97-99 parts lemon grass powder and 1-3 parts micro-silica, mixed evenly, spare; (3) in accordance with said weight takes the hydroxy propyl methyl cellulose 3-8 parts, sodium carboxymethyl starch 2-7 parts, into distilled water for 5-10% adhesive solution, the spare; (4) weighing step (2) standby mixture 300-1000g fluidized bed in the granulating, pelletizing process comprises the following steps: (A) in a fluidized air pressure as 0.12-0.15Bar, maintained under the condition of 50 °C 5-10 minutes; (B) in the fluidizing air pressure 0.12-0.2Bar, the gas flow temperature the 50-60 [...] , spray pressure 0.15-0.20Bar, liquid ejection rate 8-10g/minutes under the condition of, the step of exerting top mode (3) a binder solution is prepared, the amount of binder solution of the weight of the dry material 30%-60%; (C) adhesive after exerts , the fluidizing air pressure 0.12-0.2Bar, airflow temperature 50-60 the drying under the conditions of [...] 10-12 minutes, the water content is prepared 8-10%, the rough surface of the granule kind of circular , is necessary the lemon grass porous granule. 2. Lemon grass porous particles according to Claim 1, characterized in that the prepared lemon grass porous granule the particle size thereof is 20-60 mesh. 3. Lemon grass porous particles according to Claim 1, characterized in that the fluidized bed is preferably Midi Glatt fluidized bed. 4. Lemon grass porous particles in the application of the cigarette filter according to Claim 1, characterized in that the added in the cigarette filter rod is m 1-2mg the lemon grass porous granule.
