Method for preparing expanded stem granules for filter stick of cigarette

Abstract

The invention relates to the field of materials added to a filter stick of a cigarette, in particular to a method for preparing the expanded stem granules for the filter stick of the cigarette; the invention aims to greatly improve the production efficiency by further optimizing the process for preparing the expanded stem granules applied to the filter stick of the cigarette and achieves better technical effect of the prepared expanded stem granules. The method comprises the following steps: firstly, conducting the microwave expansion treatment on a stem; conducting the conditioning treatment on the expanded stem; granulating the conditioned stem, namely, allowing the conditioned stem to enter a granulation device, and subjecting the conditioned stem to granulation and screening, so as to obtain stem granules with the granule diameters being 26 to 40 meshes; then, conducting the recovery-sizing treatment on the stem granules, namely, placing the stem granules in a recovery-sizing device, and dewatering the conditioned stem under the microwave action until the water content is 3% to 9%; and finally, cleaning, namely, cleaning the sized stem granules to remove dust.

Description

technical field [0001] The invention relates to the field of additive materials for cigarette filter rods, in particular to a method for preparing expanded tobacco stem particles for cigarette filter rods. Background technique [0002] As a filter system for cigarette smoke, cigarette filter rods play an important role in improving the quality and safety of cigarette smoking. With the contradiction between smoking and health problems becoming more and more prominent, countries all over the world are paying more and more attention to the development of new filter rods and materials. [0003] Chinese patent application name: A new type of filter material for cigarette filter rods and its preparation method, application number: 200710066121.6, which discloses a method for manufacturing a new type of filter material for cigarette filter rods, which analyzes the raw materials and adjusts the mixture of tobacco stems Ratio, so that the total sugar content of the mixed tobacco ste...

Problems solved by technology

[0008] 4. In the preparation method of the above-mentioned patent application, the extraction process is carried out after flavoring and balancing the tobacco stem particles. There are contradictions in the actual operation of this process. If the extraction process is carried out after flavoring the tobacco stem particles If it is not processed, the flavor loaded on the tobacco stem will be extracted, and the purpose of particle flavoring will not be achieved in the end.

[0009] Therefore, the existing methods for processing tobacco stems have disadvantages such as complex process, unreasonable design, poor practicality and long-term storage performance.
