Problems solved by technology

[0007] In the above technologies, there may be the following defects: the internal structure of the prepared particles is not fluffy and porous, the specific surface area is not large enough, and the harmful substances in the flue gas are less intercepted; because the polymer binder is used in the preparation process, it may When the obtained particles are added to the filter rod for smoking, there will be an odor that is not in harmony with the smoke, which will affect the sensory quality of smoking

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...
