Description
Technical Field
The utility model belongs to the tobacco processing field especially relates to a cylinder cut-tobacco drying device.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The process of changing the moisture in the material into steam and discharging the steam to the external environment around the material is called drying, the drying and dehumidification of the cut tobacco is a diffusion process of evaporating the moisture from the inside to the ambient air, partial moisture of the cut tobacco can be removed firstly through expansion drying of the cut tobacco, the filling capacity and the processing resistance of the cut tobacco are improved, and the processing requirements of the subsequent procedures are met. Meanwhile, the aroma style of the cigarettes can be highlighted, the sensory comfort is improved, and the sensory quality is improved. In addition, the sensory quality and the physical quality of the cut tobacco can be considered, and the coordination and unification of the two can be realized.
The existing cut tobacco drying equipment can be divided into the following parts according to different structural forms and cut tobacco drying mechanisms: a leaf shred pneumatic dryer and a drum-type shred dryer. The airflow drying equipment mainly utilizes high-temperature airflow to carry out high-strength treatment on the remoistened cut tobacco so as to obtain higher expansion rate, effectively reduce the content of tar in the cigarette and remove the green miscellaneous gas of the tobacco. The roller cut tobacco dryer has the functions of drying cut tobacco leaves or cut stems at low temperature and low strength, improving the sensory quality of the cut tobacco leaves or the cut stems, and improving the filling capacity and the processing resistance of the cut tobacco leaves or the cut stems so as to meet the technical requirements of cigarettes. The drum-type cut-tobacco drier can be divided into a tube plate type cut-tobacco drier, a thin plate type cut-tobacco drier and a calandria type cut-tobacco drier according to different structures.
Taking a tube plate type cut tobacco dryer as an example, one path of hot air enters the cylinder from the feeding end, flows in the same direction and contacts with the cut tobacco, and is discharged through the moisture discharge port, so that the moisture discharge and drying of hot air flow are realized; the other path of hot air is fed into the cylinder body from the feeding end to preheat the cylinder body, and the cut tobacco continuously rolls and falls down in the circular space through the frying plate and is contacted with the heating tube plate, so that the purpose of drying the cut tobacco is achieved. In the actual processing process, hot air flows in the same direction with tobacco shreds through the cylinder to take away a part of tobacco shreds, so that the moisture removal pipeline is blocked over time, and the pipeline needs to be cleaned irregularly; due to the existence of the frying plate, the tobacco shreds are broken to a certain degree when continuously rolling and falling, so that the tobacco shred yield is reduced; two paths of hot air are needed to act simultaneously in the production process, the structure of the equipment is correspondingly complicated, and if the proportion of the two paths of hot air is not well controlled, the tobacco shreds are easily heated unevenly, and the processing strength is reduced.
The problems not only cause energy waste and tobacco shred crushing, but also restrict the improvement of the processing resistance of the tobacco shred and the highlighting of the cigarette aroma style, improve the sensory comfort and improve the sensory quality.
