Technology of re-baking of tobacco leaf and development of its automatic control system

In view of the shortcomings of the traditional technology for tobacco leaf baking and the problems of adjusting double-sided valves of the re-baking machine with double poles, the technological parameters of the tobacco leaf re-baking were studied and the changing law with other factors was obtained. The way for well-balanced adjustment of double-sided valves of the re-baking machine with double poles was found out. Based on those research results, a YWS96-B type control system of tobacco leaf re-baking machine with the function of well-balanced adjustment and self-adapted adjustment was researched and developed, which can be controlled through the pattern of hand control, keyboard control or centralized-distributed automatic control using temperatures in different baking zones and rooms as control conditions. The practical application shows that this control system has met the design requirements of continuous and stable operation, energy-saving, cost-reducing and on-line maintenance. Using this technology and automatic control system, the quality and output of the tobacco leaf were raised, and better socioeconomic benefits were obtained.
