Inventor: CHRIST MICHAEL
IPC: F26B13/10
Filed: 1998-09-29
Abstract: A fuel fired drying system for a continuous material feed has the material (WB) passed horizontally between upper and lower drying jets (3,4) fed by twin blowers which draw hot gasses from a common duct (11). The hot gasses comprise combustion gasses from the burner and recirculated gasses. If the material feed stops, a safety procedure switches the by-pass flaps for the lower drying jets to shut off the drying flow onto the material while the blower of the other jets has its speed reduced, or stopped, by a frequency switch. With the by-pass flaps switched into the safety setting a recirculating gas flow is maintained so that the drying process can be re-started at the selected temperature.
