Problems solved by technology

For example, Chinese patent document 200710066121.6 discloses a technique of adding microwave-expanded tobacco stems to granules and then adding them to the cigarette tip. However, the tobacco stem particles prepared by this technology still contain a large amount of alcohol-soluble substances, so the smoke cannot pass through. can only bypass
The tobacco stem particles prepared by this technology have only a simple interception effect on the smoke, and the reduction of tar is extremely limited.
Moreover, the tobacco stem after microwave treatment already has a specific smoke smell, and it is difficult to be suitable for different brands of cigarettes.

preparation example Construction

[0028] The preparation method of the tobacco stem filter material provided by the invention comprises:

[0029] Swelling the tobacco stems;

[0030] Extracting the expanded tobacco stems with ethanol, followed by solvent removal;

[0031] Treating the tobacco stems after the desolvation treatment with biological enzymes, and then drying them;

[0032] The dried tobacco stems are granulated to obtain a cigarette tip filter material.

[0033] According to the present invention, the tobacco stems used for expansion treatment are preferably screened and mildew-free tobacco stems, and the content of non-stem impurities in the tobacco stems is preferably below 1 wt%. The length of the tobacco stem is preferably 1 cm to 15 cm, more preferably 1 cm to 12 cm, more preferably 1 cm to 5 cm. The water content of the tobacco stems for swelling treatment is preferably 8.5wt%-15wt%, more preferably 9wt%-13wt%, more preferably 9.5wt%-12wt%.

[0034] According to the present invention, whe...

Embodiment 1

[0043] The filter material granules are made by the following steps:

[0044] Step 1, using non-mildew tobacco stem raw materials, screening the tobacco stem raw materials, the content of non-tobacco stem impurities is below 1%;

[0045] Step 2, cutting the raw material length of the tobacco stem to be controlled at 1cm to 15cm, and the water content of the tobacco stem is 12wt%;

[0046] Step 3, treating tobacco stems with microwave expansion;

[0047] Step 4, extracting the expanded tobacco stems with ethanol at a temperature of 45° C. and an extraction time of 8 hours;

[0048] Step 5, the leached expanded tobacco stems are treated with steam precipitation for 30 minutes.

[0049] Step 6, add biological enzyme treatment to the tobacco stem after desolvation (80-1 million units of cellulase activity per kilogram of expanded stem, 2-3 million units of pectinase activity, 500,000 units of laccase activity), and the treatment temperature is 36 ℃, treatment for 8 hours;

[0...

Embodiment 2

[0054] Steps 1 to 7 are identical with embodiment 1;

[0055] Step 8 is: granulating to obtain 40-60 mesh granules.

[0056] Get the filter granules that this example makes, add respectively in the A (embodiment 2A), B (embodiment 2B) according to the amount of per millimeter filter rod 1.5mg, measure the smoke index of embodiment 2A and embodiment 2B and list in Table 1, Table 2 describes the flavors measured for Example 2A and Example 2B.

Abstract

The invention provides a preparation method of a cigarette mouth filter material, which comprises the steps of carrying out expansion treatment on tobacco stems; extracting the tobacco stems after the expansion treatment with ethanol, and then carrying out precipitation treatment; processing the tobacco stems after the precipitation treatment with a biological enzyme, and then carrying out dryingtreatment; and carrying out granulation on the tobacco stems after the drying treatment for obtaining the cigarette mouth filter material. The preparation method firstly carries out the expansion treatment on the tobacco stems for improving the specific surface area of the tobacco stems, but the tobacco stems after the expansion treatment have obvious scorch aroma, and then the preparation methodfurther extracts the tobacco stems after the expansion with the ethanol, thereby removing the special scorch aroma of the tobacco stems, reducing the specific weight of the tobacco stems and leading the tobacco stems to load more aroma. The preparation method further carries out the treatment on the tobacco stems with the biological enzyme after removing the ethanol by the precipitation treatment, so as to lead filter crystals of the tobacco stems to be more crisp and loose, be conductive to lead the tobacco stem material to absorb tar in smoke and improve the absorption effect of the tobaccostems to the tar; and then the granulation is carried out for obtaining the cigarette mouth filter material.

Description

technical field [0001] The invention relates to a filter material, in particular to a method for preparing the filter material of a cigarette tip and the filter material of a cigarette tip. Background technique [0002] With the needs of social development, the safety of cigarette products has been paid more and more attention by consumers and cigarette companies. One of the important indicators that affect the safety of cigarettes is the tar content. In order to ensure the safety of cigarette products, the State Tobacco Monopoly Administration has issued a rigid timetable for reducing tar to various cigarette companies. However, since tar is closely related to cigarette smoking, developing a technology that reduces tar content and stabilizes cigarette smoking has become one of the key research directions of tobacco-related enterprises. [0003] Cigarette filters are one of the effective means to reduce the harm of cigarettes. Cut tobacco and cigarette paper are burned to p...
