The agitator of the pan dryer is heated and is equipped with speed control improving the efficiency. Moreover, the design modification of the heated flat bottom enlarges the heating area considerably. The agitated drying allows a good mixing and a thermal homogeneity which ensures even drying.
The top driven pan dryer relies on a fast agitator with a circumferential speed of up to 3 m/s ensuring optimum mixing. The lifting and lowering agitator also provides mixing on the vertical axis. At the same time, the minimal agitator to wall clearance keeps the wall free from product crust.
The mechanical seal of the pan dryer is located outside of the product area and can be either lubricated with gas or liquid. The axial motion of the agitator is sealed by metal bellows. Inspection is easily possible when the pan bottom is lowered. In the case of frequent cleaning and opening cycles, the pan dryer is also ideally equipped with a time-saving main flange bayonet quick-lock fitting instead of C-clamps.
