The particle segment 30 includes first particles and second particles, which are used to enhance the flavor of the cigarette or to adsorb harmful gases in the cigarette smoke. The weight ratio of the first particles to the second particles is a preset weight ratio, wherein the preset weight ratio is specifically set according to practical situations, and the preset weight ratio can be that the weight ratio of the first particles to the second particles is 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 and 1.0. The tipping paper 40 contains bacterial cellulose thereon.
In order to enrich the smoke feeling of the cigarettes and improve the adsorption effect of the filter tip, the first filter segment 10 is made of acetate fiber tows, and the second filter segment 20 is made of activated carbon fibers. The first particles are flavor slow-release particles for increasing the flavor of the cigarettes, and the second particles are polyethylene glycol particles.
The first particles of the embodiment are prepared by adsorbing a flavoring agent by slow-release shell powder particles, wherein the flavoring agent is one or more of crape myrtle essence, sandalwood essence, jasmine essence, rose essence, grass essence, lavender essence and peppermint essence. The slow release shell powder particles are obtained by putting clean shells into a plasma generator for cleaning, calcining, modifying by a high-pressure furnace, and mixing with chitosan.
The first particles were prepared as follows:
pretreating and modifying shell powder, namely cleaning clean shells in a plasma generator, adding the clean shells into 2-10% citric acid solution for soaking for 5-8 hours, preferably adding the clean shells into 6% citric acid solution for soaking for 6 hours in the embodiment, then performing sand cleaning, cleaning with clear water, airing and crushing into small pieces; putting the crushed shell small blocks into a tubular furnace, calcining for 4 hours at the temperature of 1000-1100 ℃, naturally cooling along with the furnace, then putting the calcined shell small blocks into a high-pressure furnace, controlling the temperature in the furnace to be 650-750 ℃, then injecting water vapor and nitrogen into the high-pressure furnace, and controlling the pressure in the high-pressure furnace to be 10-12 atmospheres for modification for 5 hours; taking out the modified shell small blocks, crushing and sieving the crushed shell small blocks with a 200-mesh sieve to obtain modified shell powder;
preparing slow-release shell powder particles, namely preparing 0.5% chitosan solution by adopting acetic acid aqueous solution with the concentration of 1%, flatly spreading modified shell powder, uniformly spraying the chitosan solution, then drying until the chitosan solution with the mass of 0.5 times is sprayed, drying and granulating to obtain slow-release shell powder particles;
and (3) mixing the slow-release shell powder particles with the flavoring agent to obtain the accessory spice, and screening out the slow-release shell powder particles to obtain the first particles.
The flavoring agent is attached to the shell powder by utilizing the porous adsorption effect of the shell powder, and then the slow release of the flavoring agent is realized by chitosan, so that the phenomenon that the flavor of the front mouths of smoking is too strong is avoided.
Example 2
The embodiment also provides a cigarette filter, the structure of the cigarette filter of the embodiment is the same as that of the cigarette filter of the embodiment 1, and the difference is that the second particles are herbal carbon particles, and the herbal carbon particles are formed by carbonizing one or two or three of rheum officinale, hawthorns and radix scutellariae.
Wherein, the process for preparing the rhubarb charcoal particles by using the Chinese herbal medicine charcoal particles is as follows: drying fresh rhubarb at 120 ℃ for 3 hours, heating to 200 ℃ for pre-carbonization, wherein the pre-carbonization time is 1 hour, heating to 320 ℃ for carbonization for 1 hour after pre-carbonization, cooling to room temperature after carbonization, crushing carbide, and sieving with a 100-mesh sieve to obtain the rhubarb charcoal-prepared herbal charcoal particles.
The preparation process of the herbal carbon particles for preparing the hawthorn carbon comprises the following steps: drying fresh hawthorns at 100 ℃ for 2 hours, heating to 200 ℃ for pre-carbonization for 1 hour, heating to 300 ℃ for carbonization for 1 hour after pre-carbonization, cooling to room temperature after carbonization, crushing carbide, and sieving with a 50-mesh sieve to obtain herbal carbon particles prepared from hawthorns.
