Types of PAN DRYER A) Top Agitation type PAN DRYER B) Bottom Agitation type PAN DRYER
A) PAN DRYER (TOP ENTRY AGITATOR TYPE) The top driven Pan Dryer relies on rotational velocity. A particularly fast agitator with circumferential speed of up to 3 m/s ensures optimum mixing. The raising 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 rotational high speed of the agitator combined with its vertical translation does not require the use of a chopper.
B) PAN DRYER (BOTTOM ENTRY AGITATOR TYPE) The vessel is equipped with a bottom driven agitator turning at low and variable speed, depending on the nature of the product to be dried and its moisture content. The agitator ensures the constant renewal of the product in contact with the Heated vessel shell and ensures a good homogeneity and a constant temperature of mixing. In Both type of Pan Dryer the heat required for drying is supplied by the circulation of hot fluid (water, steam or thermal fluid) in the insulated double jacket of the vessel (bottom, shell, cover, dust filter) and avoids areas of condensation. Loading is done at the top of the vessel in both type.
Agitator Sealing without Product Contact :- The mechanical seal of the pan dryer is also advantageously located outside of the product area. Depending on the application, it can either be lubricated with gas or liquid. The axial motion of the agitator is sealed by metal bellows, as with the Filter / Dryer.
Easy internal inspection 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 quick-locking bayonet flange instead of standard C-Clamps. Important advantages at a glance
