Pressurized Steam Fluid Bed Dryer - PSFB - A totally closed drying
system.
The Niro pressurized steam fluid bed dryer (patented) represents the most
cost-effective and environmentally friendly system for handling the vast
quantities of moist, fibrous materials produced in brewing, food and sugar
processing.
Other succesful applications include the drying of wood
based bio-fuels. Use of pre-dried fuel significantly improves boiler
efficiencies.
SOME APPLICATIONS:
- Co-products from starch production
- Distiller's dried grain and substrate
- Wood based bio-fuels
MAIN CHARACTERISTICS OF DRYING IN STEAM:
- A totally closed drying system. No air pollution. No vapour, dust or odour.
- Recovery of energy. More than 90% of the energy used in drying the product
is recovered as 2-4 bar steam
- Improved product. No product oxidation. No flue gas contamination
- No product losses
REFERENCES:
Although this is a relatively new
technology, Niro has installed several commercially sized steam fluid bed
dryers processing sugar beet pulp, as well as wood based bio-fuels, and
bio-sludge.
OPERATING MODE:
Superheated
steam has long been recognized as a drying medium offering important advantages
in terms of energy consumption, environmentally friendly processing and dried
product quality for a range of selected materials. This potential has been
fully utilized by the latest designs of Niro pressurized steam fluid bed
dryers.
Moisture evaporated from the feed material forms the
pressurized steam circulating within the dryer. Excess pressurized steam is
continuously discharged for use elsewhere in the factory to obtain maximum heat
recovery.
Niro A/S, Denmark, has entered into a licence agreement with
BMA AG, Braunschweig, Germany who has been granted the exclusive right to sell
and supply Niro's Pressurized Steam Fluid Bed Dryer (PSFB) to manufacturers in
the sugar industry world-wide. Details below.
