  • Japanese Patent Application Laid-Open No. 62-3778 discloses a method for drying cigarettes and an apparatus therefor in which a two-stage airflow drying process is continuously performed. That is, a tobacco raw material is supplied into a high-temperature gaseous medium, moves to a first separation device through a first duct, and separates the raw material and the gaseous medium. A hot gaseous medium is supplied to the second duct, while the separated tobacco raw material is supplied downstream of the first separator. The tobacco raw material and the hot gas medium are transferred to the second separation device through the second duct and separated.
  • Patent No. 4031115 has a short passage time of the tobacco raw material and the vapor in the apparatus from the description of the free fall speed, the effective height of the apparatus, and the rotational speed of the winor (200 rpm). Therefore, the tobacco raw material is not sufficiently wetted and swollen due to the short contact time with the steam. In addition, since Winoa has a rotating part, the deterioration of parts is fast. Furthermore, the tobacco raw material is easily entangled with the rotating part. Intertwined tobacco materials have a great influence on taste and physical properties.
  • US Pat. No. 4,766,912 has a structure in which a steam spraying device conveys raw materials by vibration and sprays steam from a hole in the bottom of the vibrating conveyor. For this reason, since the deterioration of the drive component due to vibration is fast, the durability is inferior. Further, vapor spray from the bottom surface of the vibration conveyor uses, for example, pores having a diameter of 0.8 mm. For this reason, scales (inorganic substances such as calcium carbonate) contained in the steam and fine powder of tobacco raw material are clogged in the pores. Pore clogging causes fluctuations in the amount of steam and destabilizes the quality of the tobacco raw material after processing.
