Description

Tobacco stem nano ternary composite filter

technical field

The utility model relates to the field of cigarette products, in particular to a ternary composite filter tip.

Background technique

Tobacco stems are the remaining veins of flue-cured tobacco after the leaves are removed. Its lignocellulose content is high and its irritation is strong. It is only added in an appropriate amount in cigarettes to increase the filling value of cigarettes and reduce the production cost of cigarettes, which limits its use in cigarette production. Currently, tobacco stems have become the largest industrial waste in cigarette production.

The mainstream smoke formed by burning shredded tobacco contains various harmful substances such as tobacco-specific nitrosamines (TSNAs), polycyclic aromatic hydrocarbons (PAHs), aldehydes, volatile hydrocarbons, and CO. Harm reduction and tar reduction have become an important part of cigarette production. an important research direction. The adjustment of flue-cured tobacco planting and curing process, the processing of shredded tobacco, and the improvement of filter materials are the three main directions for cigarette harm reduction and tar reduction. Although the adjustment of flue-cured tobacco planting and curing process can theoretically reduce cigarette raw materials from the source However, under the current technical conditions, industrial application cannot be truly realized. The processing of shredded tobacco and the improvement of filter material are the main measures to reduce harm and tar in current cigarette production, among which the improvement of filter adsorption material is the basic line of defense for cigarette harm and tar reduction. In addition to the nozzle adsorption materials, a variety of adsorption materials based on advanced technology have also been successfully applied to the filter to improve the adsorption effect of the filter on harmful substances in the mainstream smoke.

The hemoglobin adsorption material filter rod developed by Dai Ya et al. can effectively reduce various harmful components in flue gas. Beijing Tsinghua University and Beijing Cigarette Factory developed an Al ₂ O ₃ -based nano-adsorption material filter, which reduced the tar content in the smoke to about 3 mg, and the adsorption of other harmful components has not been reported. The above-mentioned kinds of adsorption materials are all exogenous materials, which can only be added to the filter rod to filter harmful components in the smoke. However, due to the need to maintain the stability of the sensory quality of cigarettes, the amount of their addition is restricted, resulting in a decrease in the adsorption effect .

Utility model content

In view of this, the purpose of the utility model is to provide a composite filter which can keep the sensory quality of cigarettes stable and has an obvious effect of absorbing harmful components.

In order to solve the above technical problems, the technical solution provided by the utility model is to provide a tobacco stem nano-ternary composite filter. The composite filter includes an outer cylindrical tipping paper, and two sections of fiber bundles are wrapped in the tipping paper. Nanoized stalks are filled between the two sections of fiber bundles.

Preferably, the fiber bundle is acetate fiber bundle.

Preferably, the length ratio of the two fiber bundles is 3:2.

Preferably, the length ratio of the two fiber bundles is 1:1.

Preferably, the filling length of the nano-sized stem particles is 1/3 of the total length of the composite filter.

Compared with the prior art, the beneficial effect of the utility model lies in that the utility model uses nano-sized stem particles with a high specific surface area, that is, nano-sized tobacco stem particles, which have a relatively high impact on harmful components in cigarette smoke. The adsorption capacity effectively reduces the release of harmful gases in the mainstream smoke of cigarettes. Using the composite filter tip of the present invention can significantly reduce the release of phenol and ammonia in cigarette smoke.

The tobacco stem nanometer ternary composite filter tip of the utility model not only reduces the harmful substances in the cigarette, but also ensures the stability of the sensory quality of the cigarette, and has very high practical value and popularization value.

The tobacco stem nano ternary composite filter tip of the utility model has a simple process for adding tobacco stem nano particles, and there is no need to worry about uneven addition of nano stem particles.

Description of drawings

Fig. 1 is a partial cross-sectional structural schematic diagram of a preferred embodiment of the present invention.

Detailed ways

The following will be described in conjunction with the accompanying drawings and a specific embodiment.

Referring to Fig. 1, Fig. 1 shows a cigarette, which includes a cigarette 20 and a tobacco stem nano-ternary composite filter 10 of the present invention. The tobacco stem nano-ternary composite filter 10 is composed of two sections of fiber bundles 11, nano-sized stem particles 12 and tipping paper 13, and the fiber bundles used in this embodiment are acetate fiber bundles. The tipping paper 13 wraps the cellulose acetate bundle into a cylinder, and the length ratio of the two sections of the cellulose acetate bundle is 3:2. As a more preferred embodiment, the length ratio of the two sections of the cellulose acetate bundle is 1:1. 12 is filled between two sections of cellulose acetate bundles to form a nano-sized stalk segment, the length of which is 1/3 of the length of the composite filter tip. Cigarette smoke passes through the nano-sized stalk section, so that harmful substances in the smoke can fully contact with the nano-sized stalk, and the harm reduction effect is obvious.

The above are only preferred implementations of the present utility model. It should be pointed out that the above-mentioned preferred implementations should not be regarded as limitations on the present utility model, and the protection scope of the present utility model should be based on the scope defined by the claims. For those skilled in the art, without departing from the spirit and scope of the utility model, some improvements and modifications can also be made, and these improvements and modifications should also be regarded as the protection scope of the utility model.
