Embodiment 1

[0040]Embodiment 1: After water extraction and solid-liquid separation, the cut tobacco stems have a water content of about 70%, and are dried to about 20% of the moisture by airflow drying equipment, and then the weight of the cut stems is used in the feeding device: the weight of the liquid = Spray 45% solid content of cut stem additives at a ratio of 1:1, the actual backfill rate is 36%, and the water content after backfill is 37.5%. The distribution is relatively even. The cut stems homogenized by the drum are sent to a single-screw continuous extrusion device for extrusion. The compression ratio of the screw extrusion is 3:1, and the rotation frequency of the screw is 25 Hz. After the extruded material is loosened by the flexible loosening device, it is found that the color is uniform. After continuous sampling and testing, the fluctuation value of the backfill rate is less than 1.5%.

Embodiment 2

[0041] Embodiment 2: After water extraction and solid-liquid separation, the cut tobacco stems have a water content of about 70%, and they are dried to about 18% of moisture by airflow drying equipment, and then the weight of the cut stems is used in the feeding device: the weight of the liquid = The ratio of 1:1.5 was sprayed with 45% solid content of cut stem additives, the actual backfill rate was 45.8%, and the water content after backfill was 40.2%. The distribution is relatively even. The cut stems homogenized by the drum are sent to a single-screw continuous extrusion device for extrusion. The compression ratio of the screw extrusion is 3:1, and the rotation frequency of the screw is 35 Hz. After the extruded material is loosened by the flexible loosening device, it is found that the color is uniform. After continuous sampling and testing, the fluctuation value of the backfill rate is less than 1%.

Embodiment 3

[0042] Embodiment 3: After the shredded tobacco is extracted with water and separated from solid and liquid, the moisture content is about 72%, and it is dried to about 30% moisture by airflow drying equipment, and then the weight of shredded tobacco: the weight of feed liquid = 1:0.5 is used in the feeding device The ratio of spraying 40% cut tobacco additives with solid content, the actual backfill rate is 22%, and the moisture after backfill is 40%. After homogenizing by the drum, it is found that some cut tobacco color is lighter microscopically, but the distribution is relatively uniform. The cut stems homogenized by the drum are sent to the upper and lower copper bar chain trapezoidal continuous extrusion devices for extrusion, and the extrusion compression ratio is set to 2.8:1. After the extruded material is loosened by the flexible loosening device, it is found that the color is uniform. After continuous sampling and testing, the fluctuation value of the backfill rate ...

Abstract

The invention discloses a method for homogenizing and mixing tobacco material and backfill liquid. The method comprises the following steps: squeezing the tobacco material mixed with the backfill liquid under a proper pressure; and keeping the mixed material to be turned over homogeneously. As a result, under the microscopic view, the tobacco material in contact with the backfill liquid can tightly come into contact with the tobacco material not contact with the backfill liquid; and the added backfill liquid is redistributed between the tobacco material in contact with the backfill liquid and the tobacco material not in contact with the backfill liquid under a definite squeezing pressure, so that microcosmic homogenization of the backfill is realized, and the tobacco material and the backfill liquid can be fully mixed and absorbed in the microscopic view.

Description

technical field [0001] The invention relates to the field of tobacco technology, in particular to a method for homogenizing and mixing tobacco material and backfill liquid. Background technique [0002] The backfilling process is used in the flavoring and filling process of the cigarette industry, that is, the backfilling liquid is added to the tobacco material to make it evenly mixed to form a finished tobacco product. Generally, the backfilling material is added to the backfilling equipment, and it is divided into flavoring and feeding according to the different materials added. In the processing of conventional tobacco, except for Burley tobacco, which is heavily loaded (up to about 20%), the proportion of other tobacco ingredients is relatively small, generally not more than about 3%. For this reason, the method of adding the tobacco is mainly to add the feed liquid into the rotary drum, and try to realize the uniform distribution of the feed liquid by rolling and conta...
