· Patil et al. (1992) conducted a series of experiments to test the flammability of fractions of chopped alfalfa (stems, leaves, and a whole mixture) in a rotary drum dryer operating between 300 and 800 °C. The study showed that the material burned even before its moisture was evaporated entirely. The results proved that the partial drying period took only .

The dryer normally operates on a two fan, balanced draught system, whereby the gas inlet is maintained under slightly negative pressure to minimise air inleakage. When drying (and/or preheating) materials which are unaffected by heat or exposure to a flame, an oil or gas burner can be arranged to fire directly into the drum.
