Tray Dryer
It is the most commonly used batch dryer.
They are box-shaped and loaded and unloaded via a door.
Inside are several heating plates mounted one above the
other on which the product is placed in trays.
The bottoms of both heating plates and trays should be
as smooth as possible to permit optimal heat transfer
between plates and product.
The medium flowing through the heating plates is water,
steam or thermal oil.
The distance between the heating plates is determined
primarily by the surface loading and the foaming of
the product.
To avoid retrograde condensation the cabinet walls are
indirectly preheated by the heating plates. The product is
introduced and heated at atmospheric pressure. Only after
all individual product trays reach the same temperature
the cabinet is evacuated and drying can start.
Double Cone Vacuum Dryer
Reduces drying time.
Eliminates need for re-drying of lumps.
Handling & exposure of final product is avoided.
Gives uniformity size dry product.
System can process crystalline or amorphous
powders which are prone for lumps.
Easy to clean internal surface, Thus ensuring
purity of product.
Optimum and continuous vacuum maintenance
during process.
Uniform material shuffling over the heated
contact surface of the cone
