Wood as
regenerative alternative for
fossil fuels is gaining more and
more importance. Benefited by
the uncertain price trend in the
field of primary energy (like
oil and gas), heating with wood
becomes important again for a
wider group of users. The
produced quantity of wood
exceeds the spent one by far.
Only approx. 40 million m³ of
the annual increase of 60
million m³ are used
industrially. This means that
approx. 25 % of the 32 billion
litres of oil spent in Germany
every year could be replaced by
wood fuel. The regional
availability of wet wood
shavings and moist wood chips
guarantees a safe and
independent supply with fuel.
Wood reduces the dependence on
fossil raw material, transfers
the added value in the region
and thus offers an additional
lucrative source of income for
farmers and forestry owners as
well as for sawmills. So wood
pellets and dried wood shavings
are fuels pointing to the
future.
Generally,
high-quality drying of the
initial product is necessary for
producing wood pellets and
chips. Forest-fresh wood can
have a water content of 40 % to
60 %. Through drying to a water
content of 10 % to 12 %, the
calorific value of approx. 2
kWh/kg is increased to approx.
4.5 kWh/kg. Thus ideal
conditions for direct firing
with a simple plant system or an
optimum ability of pelletizing
for producing high-quality wood
pellets are achieved.

The
STELA drying system is a highly
efficient and individually
adaptable modular system to dry
wood shavings and wood chips
with low-caloric heat. The
drying aims at increasing the
calorific value and creating
ideal general conditions for the
direct firing of wood chips
and the processing of wood
shavings to high-quality
wood pellets.
The wood shavings or chips from
woodworking are directly fed
into the drier by conveying
systems. The product is placed
onto the drying belt lying
underneath by means of a feeding
hopper and a distribution unit
and is distributed evenly by
means of a dosing screw. The
product layer is adapted to the
specific drying parameters of
the product by a height
adjustment and brought into the
dryer tunnel.
A hot airflow ventilates the
product layer and dries the wet
product continuously. This kind
of convective drying treats the
product with extreme care, as it
is heated up only
insignificantly primarily during
the first drying step.

The
materials for the STELA belt
drier systems reach from
galvanized steel up to special
steel, according to the specific
customers' requirements with
regard to installation etc. The
STELA belt drier system
distinguish themselves by best
accessibility of the
product-carrying assembly groups
and measuring devices in and at
the drier, by extensive doors
and inspection windows and offer
the user optimum cleaning and
maintenance possibilities for a
trouble-free operation.
Having
supplied and installed a huge
number of STELA belt drying
systems, the company Laxhuber
can look back on decades of
know-how in this field and thus
can place proven plant
technology at the customer's
disposal. The modular
construction of the drying
systems allow individual
adaptations without extra cost.
Plant designs with a throughput
rate of up to 10 t of wet
product per hour and more can be
designed. |
