New brochure: Small Scale and R&D Plants

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-FLUIDIZERŪ – for final treatment of powders, agglomerates and granules
• FILTERMAT™ – the spray dryer for drying sticky, hygroscopic, thermoplastic, slowly crystallizing and aromatic products into 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.
