Patent DE-4204771-A1 (DE)
Inventor: NIEHUES HEIKO
IPC: F26B25/22
Filed: 1992-02-18
Abstract: Cut tobacco 2 is transported through a rotary drum-shaped dryer 1 and heated by steam. The rate of heat supply corresponds to the difference between the initial moisture content and the desired final moisture content. The desired final moisture content, temperature, quantity and initial moisture content of particulate material upstream of the dryer may be taken into account to relate the output of hot steam supply 16, 17 to the dryer, to fluctuations of the condition and/or quantity of material transported toward and into the dryer. The quantity of heat to be supplied to the dryer in order to achieve a predetermined final moisture content is ascertained by determining and by taking into consideration the quantity of moisture to be expelled from successive increments of the mass flow. Additional adjustments in the quantity of heat are carried out if the actual final moisture content departs from the desired final moisture content. <IMAGE>
