General
Schematic diagram The TG200 is an ultra-modern, highly efficient product from the
firm Retsch GmbH.
Through the fluidized bed technology (see schematic diagram) and
the generously dimensioned drying vessels materials can be dried
effectively in the TG200 within a few minutes.
The air throughput and heating power can be set separately, the
temperature reached depending on the air throughput and the
material to be dried.
In this process agglomeration, as with conventional drying
processes, is avoided to a considerable extent; further processing
is thus facilitated.
A large selection of accessories makes it possible to use the
machine for many different applications (see section on
accessories).
Mode of operation of the TG200
TM
Air filtered on the suction side (filter quality – pore size 30 µm) is
passed through a radial fan into the heating chamber. The heated
air then enters the drying vessel and brings about continuous
circulation of the material to be dried through the fluidized bed
technology in the drying vessel.
See schematic diagram.
The hot air removes moisture from the material to be dried and
escapes through the filter bag or filter element (30 µm pore size).
The temperature is measured below the drying vessel in the air
stream.
See photo – temperature measuring point TM.
On completion of the drying process the vessel with dried material
can be easily removed.
When removing the lid and drying vessel hold this only by the
plastic grips or clamping elements provided. We recommend the
use of protective gloves.
Risk of burns on hot metal and glass components.
