Niro has released a new brochure for customers who wish to know
more about the opportunities on offer for small-scale and R&D spray drying
plants.
R&D and small-scale production
plants
Niro produce a comprehensive range of versatile spray
drying plants for R&D and Small-scale production. The experience gained
from supplying over 10,000 plants across the world in over 70 years can be seen
in the attention to detail and performance of each plant produced today.
From proof of concept through laboratory and pilot plant testing to
scale-up and project fulfillment, Niro offers unmatched engineering knowledge
and experience – all tailored to produce individual solutions to specific
customer requirements.
Atomization choices
Niro
offers a range of atomization solutions, each carefully designed to produce
varying product properties:
• Rotary atomizer – centrifugal forces
within an atomizer wheel act on a liquid feed to accelerate the feed to a point
where it leaves the wheel as small droplets before being discharged into a hot
drying gas. A wide range of wheel designs and sizes are available for both
abrasive and non-abrasive feeds.
• Two-fluid nozzle, co-current or
fountain mode – high velocity, compressed air or gas acts on the feed to
produce carefully controlled particle sizes. The particle size can be selected
by changing the nozzle flow ratio between the atomizing medium and the feed.
• Pressure nozzle, co-current or fountain mode – atomization results
from converting the energy within the liquid feed into kinetic energy: pressure
applied to the feed within the nozzle forces the feed out of the orifice,
creating atomization. This atomization technique delivers a narrower particle
size distribution than other types of atomization, the size of which can be
altered by changing the feed pressure and/or nozzle size.
Powder engineering
Tailoring the drying process to
achieve the specific particulate size, structure and moisture content for an
application is a discipline that Niro has refined and improved over many
decades, making Niro the world leader in spray dryer powder engineering.
Niro Test Center
In addition to the many years of
supplying an unmatched range of spray drying plants, Niro’s own test center –
the largest facility of its type in the world – is able to offer advice,
validate processes and is supported by on-site laboratories and pilot plants.
Plant types
Niro offers customers a range of
solutions as no one process nor application is suitable for all applications.
Currently, Niro offers the following plants:
• MOBILE MINOR™ – this
flexible, easy-to-handle laboratory spray dryer offers customers the
opportunity to produce small, representative powder samples
• PRODUCTION
MINOR™ – a spray dryer with interchangeable atomization and powder discharge
systems
• VERSATILESD™ – models offer both open and closed cycle options,
with a wide range of standard spray drying modules that can be configured to
meet various customer specific requirements
• FSD™ and FSD MINOR™ – this
fluidized spray dryer uses multi-stage drying technology on a small-scale for
the production of coarse, dustless and free-flowing agglomerates
• IFD™ and
IDF MINOR™ – the integrated filter dryer features spray drying and
agglomeration, second-stage drying, powder cooling and powder separation
integrated in a compact unit. This plant also offers a high level of
containment and simplified powder handling (no need for cyclone nor external
bag filters)
• SWIRL FLUIDIZER™ MINOR – produces fine, homogenous and
non-agglomerated dry product from pastes, filter cakes and viscous liquids
• VIBRO-FLUIDIZER® – for final treatment of powders, agglomerates and
granules
• FILTERMAT™ – the spray dryer for drying sticky, hygroscopic,
thermoplastic, slowly crystallizing and aromatic products int
o free-flowing, agglomerated powders.
Process control
Niro’s well-proven control and automation systems provide safe, flexible
operations with full visibility. Options range from simple push-button panels
to advanced PLC/HMI solutions. Throughout the entire process, all Niro spray
dryer systems and units provide the users with security of experience
unsurpassed in the marketplace.
