Description

A kind of composite filter rod containing tea and preparation method thereof

technical field

The invention belongs to the field of cigarette processing, and in particular relates to a composite filter stick containing tea and a preparation method thereof.

Background technique

At present, cigarette filters generally use polypropylene fiber or acetate fiber filter rods. The chemical properties of the tow used are relatively stable, and it is not easy to decompose under normal circumstances. Therefore, after cigarette consumption is completed, it becomes garbage that is not easy to handle and will pollute the soil.

Tea contains more than 450 kinds of organic chemical components and more than 40 kinds of inorganic mineral elements. The organic chemical components and inorganic mineral elements in tea contain many nutrients and medicinal ingredients, which have special functions of detoxification and sterilization. At the same time, the aroma substances in tea can also produce a pleasant fragrance.

In the existing technology, tea powder is directly added to the filter rod, or mixed with other substances to make granules and then added to the filter rod. These powders will absorb the plasticizer used for filter rod molding, which will affect the molding and filtration efficiency of the filter rod. At the same time, it is also easy to block the processing machinery. After being rolled into cigarettes, the powder is also easy to enter the mouth, causing harm to the human body. Although the tea powder mixed with other substances to form granules weakens the adverse factors brought by the powder, it will bring serious problems. Tea aroma affects the characteristics of tea aroma and the quality of cigarette aroma.

Contents of the invention

Aiming at the problems in the prior art, the invention provides a composite filter stick containing tea leaves. There is no dust pollution during the filter rod processing, no clogging of processing machinery, and no danger of powder entering the human mouth. The obtained tea-flavored cigarette smoke is in full contact with the tea shreds, and the tea aroma and tobacco aroma are well integrated, and there is no aroma component. Layer phenomenon, soft cigarette aroma, prominent tea aroma characteristics, reducing the amount of tow filter rods, reducing soil pollution.

Specifically, the present invention provides the following technical solutions:

A composite filter rod containing tea leaves is composed of a molded wrapped filter core, the filter core is divided into three sections, the two ends are ordinary fiber tow filter rods (1), and the middle is a tea silk filter rod (2).

In the present invention, the tea shreds are from one or more of white tea, black tea, yellow tea, black tea, green tea and green tea.

In the present invention, the water content of the shredded tea leaves is 8-11% (eg 8%, 9%, 11%).

In the present invention, the preparation method of the tea shreds can utilize the methods in the prior art. For example, the finished tea leaves can be rehydrated to a moisture content of 16% to 21% (such as 16%, 18%, 21%), and shredded at 56°C to 64°C (such as 56°C, 59°C, 64°C). Width is controlled at 0.6-0.9mm (such as 0.6mm, 0.7mm, 0.8mm or 0.9mm, preferably 0.7mm), and the water content is adjusted to 8-11% (such as 8%, 9%, 11%) after shredding to obtain tea shreds .

Further, the tea silk is rolled into a tea silk filter rod, and then the composite filter rod containing tea leaves according to the present invention is wrapped with the ordinary fiber tow filter rod by forming paper, as shown in Figure 1, the ordinary fiber tow in the filter rod The filter stick (1) is placed at both ends, and the tea silk filter stick (2) is placed in the middle. When the cigarette is rolled, the compound filter rod containing the tea leaf of the present invention is wrapped with pine paper to become a filter tip, and connected with cigarettes (3) as a whole to form a cigarette.

In the present invention, the common fiber tow filter stick is acetate fiber tow filter stick and/or polypropylene fiber tow filter stick.

The present invention also provides a method for preparing the tea-containing composite filter stick of the present invention, which is to rehydrate the finished tea leaves to a moisture content of 16% to 21% (such as 16%, 18%, 21%), Shred at 64°C (such as 56°C, 59°C, 64°C), the width is controlled at 0.6-0.9mm (such as 0.6mm, 0.7mm, 0.8mm or 0.9mm, preferably 0.7mm), and the moisture content is adjusted to 8～11% (such as 8%, 9%, 11%) obtain tea shreds, the tea shreds are rolled into tea shreds filter rod, and then with common fiber tow filter rod by molding paper wrapping the present invention containing tea A composite filter rod, wherein the ordinary fiber tow filter rod (1) is placed at both ends of the composite filter rod, and the tea silk filter rod (2) is placed in the middle.

The present invention also provides a cigarette, the filter rod of which is the composite filter rod containing tea according to the present invention.

The advantages of the present invention are that: the composite filter rod of the present invention contains tea silk filter rods, which can reduce the amount of chemical fiber materials and reduce soil pollution, and will not generate dust pollution during the processing of tea silk filter rods, will not block processing machinery, and does not exist Hazard of powder entering human mouth. In the present invention, after the tea silk is rolled into a filter rod, as a section of the composite filter rod, on the one hand, it can filter flue gas and achieve the effect of reducing coke and damage; on the other hand, the tea silk is looser than acetate fiber, When smoking, the smoke can stay in it, which can fully integrate the aroma of cigarettes and tea, and there is no aroma layering phenomenon. The aroma of cigarettes is soft, and the characteristics of tea aroma are prominent, which improves the overall quality of cigarette aroma.
