Drying 715 The dished head is provided with the appropriate nozzles for feed inle instrumentation, heating or cooling medium, vapor outlet, lamp and rupture disk. The dished head and the cylindrical body are separated by means of a hydraulic system to provide easy access to the vessel for inspection or eaning. A high powered agitator having two crossed arms located at different heights, is designed for processing products that go through a viscous transition phase(high viscosity). The same dryer can be provided with a different agitator, high speed, which is applicable for low to medium viscous products. The agitator can be totally heated. To eliminate possible agglomerates or lumps formed during the drying process, and discharge problems, a chopper device is supplied. The shaft sealing can be either tuffing-box or a mechanical seal a bottom discharge valve for the dry product is hydraulically driven and located in a closed hatch. The geometri l volume of these vertical dryers ranges from a few liters to approximat 500 liters(see Table 3) Table 2.
