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 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.
