Sewage sludge drying
__________________________________________________________________________
The company Laxhuber GmbH is one of the
leading suppliers of drying plants. The product range
includes most different drier designs, like e. g. belt drier,
drum drier, feed and turn drier or tray drier, including the
appropriate air and heating systems. Stela driers are
applied in the food, feed and chemical industry as well as
in the environmental and waste technology.
With more than 2.400 drying plants supplied for the most
various products, we have gained wide experience and
know-how. Constant development and optimization by a
competent team of engineers guarantee quality and
performance.
So meanwhile Stela Laxhuber GmbH is market-leading in Europe
e. g. in the field of agricultural driers.
Several belt driers were built so far especially for sewage
sludge.
This system was optimized and further developed on the basis
of the experience values of these plants as well as by means
of additional laboratory tests. Thus we now can supply a
powerful drying unit with the following characteristics:
simple and clear construction by few proven and tested
components
small space required
uncomplicated operation and maintenance because of the small
and clear system
flexible to install (air and heating system variable to
place). Realizable as single or multi-
belt drier, depending on the space available and the throughput rate
cooling zone for product cooling
dedusting of the exhaust air
heat
recovery by means of exhaust air recirculation (circulating
air system); thus
reduction of the exhaust volume flow and reduced consumption
waste heat utilizing of the heated cooling air
alternating air duct system (upper and lower ventilation) or
multi-belt system for careful
and constant drying of the product
parts with product contact largely made of stainless steel
to increase the operating time
fast
and problem-free start-up and shutdown
high-quality final product, granulated, dust-free,
hygienized, storable
best
accessibility to the product-carrying parts at the drier (drying
belt) by means of
extensive doors and inspection windows; thus optimum control and cleaning
possibilites
fully automatic 24 h operation possible
automatic belt cleaning brushes to reduce the waiting period
full
and partial drying in one step, drying degree adjustable
from 60 up to 95 % DS
low-temperature drying at 100 up to 130 °C. Long operating
life through low heat stress;
low vapour stress; fast start-up and shutdown through small heat storage
capacity.
flexible heating through the most various sources of energy
(fuel oil, natural gas, sewer
gas, steam, water, thermal oil)
utilization of low-calorific, external waste heat (air, flue
gas, water, steam) possible
without any problems
drying without remixing of dry product
product conveyance by the moved belt. No frictional,
shearing or centrifugal stress of the
product. No product abrasion. Long operating life through minimum
wear.
Exactly defined, variable retention time. Thus optimum
adaptation to the required DS
content and throughput rate.
The equipment as well as the process engineering of the
Stela drier for sewage sludge are techniques proven for many
years. We use them to the full satisfaction of a great
number of customers.
The company Stela Laxhuber GmbH offers engineering,
production, commissioning and service together, for
mechanics and electrics. Thus fast service and supply of
spare parts are guaranteed.
Many years of experience, our team of qualified engineers
and our modern manufacture guarantee the utmost
functionality and reliability. Only these central
competences made us one of the leading manufacturers of
drying plants.
