Background
At present, a plurality of tobacco production enterprises at home and abroad adopt devices such as an airflow type cut tobacco dryer, a drum-type cut tobacco dryer and the like to dry expanded cut tobacco on line.
The air flow type tobacco shred baking machine takes superheated steam as a medium, and the tobacco shreds which are preheated and added with water in advance are conveyed into a vertical or large-radian bent pipeline to be heated, so that the water in the tobacco shreds is quickly vaporized, and the qualified tobacco shreds are produced. The main structure of the airflow cut tobacco drier is that the cut tobacco feeding port and the feeding airlock thereof are connected with a heating pipeline and a Venturi drying pipeline which are communicated with each other through a loosening accelerator, and connected with a cut tobacco discharging airlock through a cyclone separator or a tangential separator. The main process comprises the following steps: the process gas is heated by a combustion furnace, the temperature is raised to 350 ℃ at most, the process gas enters a Venturi output pipe, the cut tobacco enters from a feed inlet through a rotary airlock, and the cut tobacco and the process gas are mixed by a Venturi pipe and enter a drying pipeline. In the drying process, a small amount of water is sprayed into a hot air pipeline connected with the combustion furnace in a short time, so that the output temperature of the combustion furnace is regulated and controlled; the process gas and tobacco mixture enter the separator, and the tobacco slowly slides into the lower discharge airlock under the action of centrifugal force. And a part of the process gas is discharged through the main process fan, a part of the process gas is directly returned to the combustion furnace for heating, and a part of the process gas is directly returned to the hot air pipeline and is converged with the hot air pipeline at the outlet of the combustion furnace to reach the required process gas temperature.
The airflow type cut tobacco dryer has the advantages that the high-temperature rapid drying is realized, the expansion rate is high, but the cut tobacco is conveyed and dried through the pipeline, the drying strength is high, the cut tobacco is not uniformly distributed in the pipeline, and the problems of cut tobacco agglomeration and large outlet water fluctuation exist.
The drum-type tobacco shred baking machine uses steam as a heat source, and tobacco shreds which are preheated and added with moisture in advance are conveyed through the rotation of a drum heated by the steam and are heated in the drum, so that the moisture of the tobacco shreds is slowly vaporized at a lower temperature, and qualified tobacco shreds are produced. The main structure of the drum-type cut tobacco drier is that a feeding cover of cut tobacco is connected with a roller ring connected with one end of a drum through soft sealing, the other end of the drum is connected with another roller ring and connected with a discharging cover through soft sealing, and shoveling plates arranged on the inner wall and the inner wall of the drum are heated through steam. The main process comprises the following steps: the tobacco shreds enter the cylinder body through the feeding cover and are conveyed to the discharging cover through the slow rotation of the roller to be discharged. Steam is introduced into the inner wall of the cylinder body and the shoveling plates on the inner wall, the temperature is about 100-150 ℃, the tobacco shreds are subjected to heat radiation, and meanwhile, the tobacco shreds are heated by passing hot air of about 100-120 ℃ into the cylinder, so that the tobacco shreds are dehydrated and expanded at a lower temperature for about 4 minutes.
When the drum-type cut tobacco dryer dries cut tobacco, although the moisture at the cut tobacco outlet is uniform and stable, the expansion rate is low due to the slow speed of conveying the cut tobacco, the cut tobacco is crushed greatly, and the phenomenon of dry ends is caused.
Chinese patent CN106072744A publicationThe method comprises five stages, namely a preheating stage, a stub bar unstable state control stage, a prediction belting stage, a stable state drying stage and a stub bar control stage, and the moisture content of the material is adjusted by adopting a staged gradual control mode. In the preheating stage, equipment is preheated by adopting the temperature delta T lower than the formula temperature; when the continuous passing time of the materials on the belt weigher exceeds t before the tobacco shred drying procedure0In time, adopting a stub bar unsteady state control parameter; when the water content of the material at the drying outlet is more than W1The control parameter of the material-carrying stage is predicted and delayed by t2Then, entering a steady-state drying stage, starting PID (proportion integration differentiation) regulation of the temperature of the cylinder, the temperature of hot air and the moisture discharge opening, and delaying t3And then, entering a material tail control stage, and adopting material tail control parameters. But the conveying speed is slower, and the production capacity of the existing airflow type cut tobacco dryer equipment cannot be achieved.
