Adjustable steam treatment for food ingredients and protein powders
GEA Steamfusion Nozzle
The GEA Steamfusion Nozzle for our FSD® and TFD® spray dryers is
uniquely designed to carry out instantaneous, controllable steam treatment of
your feed within the spray nozzle itself. This in-process steam treatment can
be a great option when you want to process spray dried starch, proteins or food
ingredients with specific properties. The nozzle is interchangeable with other
nozzles designed for the GEA NAD (nozzle with adjustable diameter) nozzle lance
system that fits into our DDD® (direct duct air disperser).
How does it work?
Steam is applied to the product feed directly as it passes through the GEA Steamfusion Nozzle. To achieve this the product feed is finely dispersed by the feed nozzle into the steam environment inside the steam cap. The product feed is heated instantly in the steam before being sprayed into the hot air of the spray drying chamber, where the droplets are dried to particles.
The spray angle, feed flow and feed pressure within the GEA Steamfusion Nozzle can all be adjusted. This level of fine tuning lets you create products with desired structural or functional properties. This can include carrying out starch gelatinization, creating proteins with specific properties, or manufacturing specific high-density products. The high temperature steam also reduces microbial load.
As well as affording opportunities for carrying out product functionalization, this steam heat approach may offer advantages over other heat treatment methods. When using the nozzle steam heating is instantaneous, and product is kept at high temperature for a very short time. The product is also effectively dried and cooled after it leaves the nozzle on entering the spray drying chamber.
Focused on your production needs
We always listen to our customers’ challenges and expectations so that we can develop and deliver hardware components and complete plants, digital tools and automation systems that make spray drying technology more flexible, productive and user friendly. When designing the steamfusion nozzle we kept a focus on helping to reduce issues such as nozzle blockages and deposits from nozzle spitting, and feed line fouling.
The steamfusion nozzle lance can be switched in and out of the NAD nozzle system quickly and easily, for speedy changeover and minimal downtime. The nozzle is also designed to handle conditions of high feed viscosity that can result from these high heat conditions. High viscosity can be problematic when using other heat treatment approaches and equipment, such as UHT or heat exchangers.
We’ve dedicated decades of spray drying knowhow and expertise into developing modular, flexible technologies and end-to-end lines that give you the freedom to create high quality powders with precisely defined properties. We also want you to be as confident as we are that our systems will give you great performance and deliver the results you expect.
GEA Steamfusion Nozzle, user-friendly nozzle design
Features and benefits of steam treatment using the GEA Steamfusion Nozzle:
- Instantaneous steam treatment of feed within the spray drying nozzle
- Feed flow and pressure are easily set for each product
- Quick change in and out of the NAD nozzle system
- Short residence time in the nozzle
- Immediate drying of steam-treated feed upon atomization in the spray dryer chamber
- Hygienic, user-friendly nozzle design
- Compatible with 24/7 operation, dependent on product
- Smooth, automated switching between feed lines results in increased dryer capacity and up time.
How does it fit into the spray dryer?
We’ve developed the GEA Steamfusion Nozzle as an ideal option for the CIP-compatible NAD nozzle lance system, which fits into the DDD® air disperser for GEA spray dryers. NAD lances are introduced at the side of the DDD® air disperser, not from the top. This feature allowed the design of a steamfusion nozzle that can be angled and that is also highly adjustable.
One advantage of this combined DDD® air disperser – NAD nozzle system is the shorter lances, and the flexibility to change the position of the nozzles, so you can alter the distance between the atomization nozzle in the system, as well as the distance between each atomization nozzle and wall chamber. This flexibility means you can better control interspray agglomeration and reduce powder deposits on the chamber walls.
We believe that our DDD® technology gives you more operator friendliness, great control of unwanted powder deposit and fouling, so you can be more confident of reproducible, high-quality processing, and longer production runs between CIP. The DDD® air disperser system may help you to achieve comparatively better energy efficiency and draw less power than other types of air disperser because it results in a significant decrease in pressure drop.
The DDD® air disperser in addition supports 24/7 spray drying, and features an improved nozzle lance design, which is ideal for our steamfusion nozzles. The DDD® system is compatible with our compact SPRAYEYE® and SPRAYEYE® IR nozzle cameras. These can be installed in our DDD® air disperser with easy access, to provide an extra layer of safety and process oversight for your spray drying plant.
Testing with the nozzle
At our spray dryer centre of excellence in Soeborg, Denmark, you can see the GEA Steamfusion Nozzle in action. Whether you are an existing GEA customer or are new to the FSD® and TFD® spray dryers and associated equipment, we can walk you through it all, and demonstrate our components and equipment as part of a complete spray drying setup at pilot scale, along with upstream and downstream equipment.
Together we can evaluate and optimize dryer configurations for different product types and applications, and we may even be able to test the spray drying system with your product. Be assured we’ll always give you straight, honest advice and support, so that you can be confident of a final spray dryer configuration that will match your process- and product-related needs and expectations, and that will also fit in with your existing or new site layout.
