Problems solved by technology

However, while this composite filter selectively absorbs the harmful components of the smoke, it also causes a relatively large loss of smoke moisture and some flavor components, thereby adversely affecting the smoking quality of cigarettes.

Embodiment 1

[0024] Prepare a composite filter adsorption material, wash the yam of the Dioscoreaceae plant, remove impurities such as sediment, and slice it for later use; place the cut yam slices in the sun for 12 hours to dry the moisture on the surface, and then The yam slices were steamed with steam at 100°C for 15 minutes to remove the bad smell in the yam, and then placed for 2 hours and then humidified by steam, and the yam slices were dried with superheated steam at 300°C to improve its internal structure and control its odor. The final moisture content is in the range of 10% to 15%. Finally, the yam slices are crushed into fine particles and passed through a 40-mesh sieve to obtain the required composite filter adsorption material.

Embodiment 2

[0026] Repeat Example 1 with the following differences: the yam slices were steamed for 5 minutes with 150° C. steam, and left for 5 hours.

Embodiment 3

[0028] Repeat embodiment 1, have following difference: use 350 ℃ of superheated steam drying yam slices.

Abstract

The invention discloses complex filter tip adsorption material, a preparation method and application thereof. A root, a tuber, a bulb or a corm of a plant are selected to be made into fine particles of 40-60 mesh sieves after being cleaned, dried, wet-steamed, steam-dried and grinded. The particles are added in a filter element to obtain binary composite filter tip. With the specific internal spatial structure of the plant root and the stem, the invention can selectively filter and absorb harmful components in flue gas to improve the cigarette safety. At the same time, because the plant root and the stem contain ketones and saponin materials, the flue gas can be organically resolved in smoke fragrant components when flowing through the filter tip. The richness of the smoke fragrant is increased and the suction quality is improved. The material has the advantages of safety, environmental protection, degradable performance, simple preparation process, low cost and good application prospect.

Description

technical field [0001] The invention belongs to the technical field of cigarette material preparation, and in particular relates to an adsorption material used for a composite cigarette filter. At the same time, the invention also relates to the preparation method and application of the adsorption material. Background technique [0002] The advent of cigarette filters in the 1960s effectively reduced the amount of tar in cigarettes. The contribution of the filter tip to reducing harmful components such as tar and nicotine in cigarettes lies in the selective filtration of the particulate matter in the smoke by the filter rod. When the cigarette is smoked, the smoke passes through the filter tip and enters the oral cavity. After contact with the nozzle fiber tow, some will be absorbed and cannot be returned to the air flow. In the prior art, in order to further enhance the filtering and adsorption functions of the filter, more materials with large specific surface area and s...
