Constructive design
For the design of the
drying plant, there are numerous variants, which
are assembled individually. According to your
wishes, you will receive an optimal design for
your application with the suitable components.

Design with
centro separator
The free flowing
product is fed into the store tank (1), runs due
to gravity through the drying (2) and cooling
elements (3) until it is discharged in batches
by the discharge device (4) into the discharge
hopper (5). Burner (6) and air heater (7) –
direct or indirect heating are optionally
possible - heat up fresh air. The exhaust air of
the cooling elements is mixed with this air.
Thus the whole heat stored in the product is led
back to the drying process (energy saving by
heat recovery). The large-scale hot (8) and
exhaust air caps (9) guarantee an optimum air
and heat distribution in the drier column.
The hot air flows through the product pile,
absorbes moisture and is sucked off from the
exhaust air cap by the exhaust fan(10).
The dust-laden exhaust air is cleaned in the
centro separator (11) and carried off into the
open air. The separated dust gets through pipes
to the dust bin or to a bagging device.

Design with
circulating air
Not only the exhaust air from the cooling zone,
but also the exhaust air (and so the contained
energy) from the lower drier elements is
recovered by means of a circulating air fan
(10). A pneumatic discharge slide (4) brings
about short discharge cycles. By means of
pneumatic air flaps, which are installed
blow-out-sided at the fans (10), the air flow is
interrupted during this short discharge cycle.
The share of the total air volume that can be
recovered as so-called circulating air depends
on the initial moisture of the product which is
expected on an average and on the parameters of
the ambient air. So the plants are calculated
and designed depending on the site – e. g.
Central Europe, Southern Europe or the Tropics.
A drier in Central Germany, which is designed
mainly for maize drying with an average initial
moisture of 35 %, requires another air
distribution than e. g. a drier in Southern
Hungary, where average initial moistures of 22 %
are expected.
