Example Embodiment

[0042] Example 1

[0043] (1) Pretreatment

[0044] The tea stalk raw materials are pretreated to remove impurities such as iron filings, mud and dust in the tea stalks to obtain the tea stalks that have been cleaned;

[0045] (2) Expansion treatment

[0046] The tea stems that have been removed in step (1) are expanded by microwave, with a microwave power of 15kW and an expansion time of 150s, so that the tea stems are expanded to more than 160% of the original volume to obtain expanded tea stems;

[0047] (3) Heat treatment

[0048] Under anoxic conditions, heat the expanded tea stems obtained in step (2) to 120°C by superheated steam or inert gas, and keep it at this temperature for 300 minutes;

[0049] (4) Regain treatment

[0050] Step (3) The expanded tea stalks obtained after the heat treatment are stored in a cool, ventilated, and moisture-proof natural environment for 3 months, and then enter the moisture regain balance stage. The moisture content of the tea stalks is adjusted to...

Abstract

The invention relates to a method for treating tea stems to prepare filter stick flavor increasing particles by the microwave expansion technology. The method comprises the steps of pre-treating; expanding; heating; wetting-back; granulating. The filter stick flavor increasing particles prepared by the method have the advantages of being of an inner structures and an irregular loose multi-pore form, large in specific surface area, in fully contact with smoke, effectively reducing the contents of harmful substances such as total peculate matters, tar, nicotine and CO in the smoke, being high in flavor remaining performance, improving the suction flavor of cigarette, enabling fine and soft smoke, and reducing smoke irritation; in addition, the prepared particles are high in later processing performance and suitable for industrial cigarette production.

Description

【Technical field】 [0001] The invention belongs to the technical field of cigarette processing. More specifically, the present invention relates to a method for preparing filter stick aroma-enhancing granules by using microwave expansion technology to process tea stems. 【Background technique】 [0002] Cigarette filter rods are an important part of cigarette products. On the one hand, it intercepts and filters the mainstream smoke to reduce harm and coke; on the other hand, it modifies and enriches the characteristics of the smoke to improve the quality of cigarette smoking and highlight the individual characteristics of the product. [0003] With the deepening of harm and coke reduction in the industry, the reduction of harm and coke has also brought about the problem of a decline in the richness of the aroma of cigarette products. Therefore, various flavoring forms and flavoring substances have gradually emerged in the industry and applied to various cigarette products. F...
