Working instructions

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).

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.

Since the attainable temperature depends on the set fan
power, the charged material to be dried and the type of
clamping lid, the table below serves as a guide. The
temperature in the TG200 is measured at the measuring point

TM.

Operating conditions 1:

TG200 without material to be dried, with basic equipment –
clamping lid with filter bag and 6 ltr glass vessel as separate
accesory, Art no. 72.783.0001

Operating conditions 2:

TG200 without material to be dried and with attachment with 3
glass vessels, each of 0.3 ltr, as separate accessory - Art. No.

72.002.0005

General

Do not clean the TG200 with running water.

Danger to life through current surge.

F1

The 3 filters F1 on the rear side of the machine must be
replaced after approx. 100 hrs. The maintenance interval is
shortened depending on the dustiness of the surroundings. This
must be assessed empirically by the operator.

If the filter elements and bags are contaminated too much the
efficiency of the TG200 will be reduced to an unknown extent.

Cleaning

TG200

The TG200 should be cleaned only with brushes, and possibly
with an industrial vacuum cleaner or with compressed air.

The system of protection for the TG200 with drying vessel
and clamping lid is IP43.

Without vessel and lid this is reduced to IP22.

Filter bags

The filter bags can be washed out under running water.

Filter elements and filter on the machine rear side

These must be replaced when contaminated.

Drying vessels 6 and 0.3 litres

These can be cleaned under running water or in an ultrasonic
bath.
