In back to back start-up period II, more and more fresh air is incorporated in described process air.Correspondingly open described fresh air valve FL, and close described process air valve PL with increasing degree.Substantially when proportional with described fresh air valve FL, control described exhaust gas valve AL, wherein also exist in accordance with constant deviant (Offset) or the feasible program of preserving straight line equation in described governor motion.Described exhaust gas valve AL opens together with described fresh air valve FL thus.
Roughly in the center of described region II, the temperature (Reference numeral 60) measured by the tobacco material T* that loosens is lower than described temperature rating (Reference numeral 62).This causes following result: feed back the fresh air share in described process air, this means, closes described fresh air valve FL further, and opens described process air valve PL once again further.
Finally in the III of region, reach a kind of stable state, the valve position of described fresh air valve FL, exhaust gas valve AL and process air valve PL only stands less fluctuation.By the actual temperature of the tobacco material T* loosened can be adjusted to except less deviation make every effort to the rated value 62 that reaches.
