Where the Dahmes ThermaShear™ Nozzle Shines

Real-world applications and opportunities 

The Dahmes ThermaShear™ Nozzle was never meant to be a lab toy or a showpiece just for our R&D Center dryers. In this final post of the series, we'll look at where it fits best, and the options it opens up that conventional atomization can't. 

Compact spray drying for constrained spaces 

Plenty of processors work in buildings where a tall spray tower or a big new chamber just isn't practical. Ceiling height, structural limits, and existing layouts all cap what's possible. Many of these plants still run aging, low-profile dryers that are getting harder to operate and support. 

Because the ThermaShear Nozzle does more evaporation with less air, with high-temperature, high-velocity air handling both the atomizing and the drying, it enables smaller chambers for the same water removal, lower building-height requirem

ents, and compact, low-profile dryers that still deliver serious throughput. 

That makes it a strong option for sites that need more capacity, or a modern replacement for an aging low-profile dryer, without a major building addition. 

Ideal applications for the ThermaShear Nozzle 

Based on development work at the Dahmes R&D Center and decades of in-field experience with the challenges processors face, a few areas stand out as especially well-suited to the ThermaShear Nozzle. 

1. Dry egg applications (food-grade, pet-grade, and breaker eggs) 

Egg drying spans a wide range, from high-value food-grade whole egg, yolk, and albumen powders to pet-grade egg ingredients and breaker-egg byproducts. Each segment has its own challenges, but they share a theme: egg products can be viscous, heat-sensitive, and prone to fouling or unstable atomization, especially in older dryers that weren't built for today's throughput expectations. That makes the ThermaShear Nozzle a strong upgrade option across the egg sector. 

Food-grade egg powders demand reliable drying performance, cleanability, and consistent particle characteristics. The ThermaShear Nozzle's ability to handle higher-viscosity egg concentrates lets processors push more water removal into the evaporator and take load off the dryer, a real advantage where sanitation standards are strict and uptime is critical. 

Pet-grade egg powders often run on older dryers or in constrained facilities. Here, the combination of lower pump pressure, reduced nozzle wear, and higher tolerance for solids delivers practical, measurable gains while keeping capital needs manageable. 

Breaker eggs remain a relevant subset, especially for processors handling off-spec shell eggs, floor eggs, or mixed egg streams bound for pet food and animal feed. These feeds are more variable and can carry small particulates. The ThermaShear Nozzle's larger orifice and resistance to plugging make it a more forgiving, more reliable choice in those conditions. 

Across every egg application the opportunity is the same: a practical path to modernize egg-drying capacity and efficiency without a new tower or major structural changes. 

2. Palatants 

Palatants are the flavor enhancers that give pet food its aroma and taste, typically made from enzymatically treated meats, livers, or organ-based extracts. These materials can be thick, sticky, high in solids, and occasionally abrasive, and they're produced in high volumes for a competitive market where reliability and cost efficiency matter. 

The ThermaShear Nozzle suits palatants well because it handles high-viscosity, protein-rich slurries without the plugging risk common to high-pressure nozzles, runs at lower liquid pressure to reduce wear from abrasive ingredients, and delivers strong water removal in compact equipment, a fit for the many palatant facilities operating in older buildings or tight footprints. For processors looking to increase throughput or stabilize difficult formulations, it offers a durable, predictable drying method. 

3. Meat slurries and animal proteins 

Meat and poultry processors often generate slurries or emulsions that end up as pet food or feed ingredients. These streams can include bone fragments and hard particles, abrasive components, and batch-to-batch variability. 

The ThermaShear Nozzle helps by providing a larger flow path that tolerates particulates better than small high-pressure orifices, reducing mechanical wear by pumping product at around 200 psi instead of 4,000, and lowering the risk of unplanned downtime from clogging or nozzle failure. For plants where uptime and throughput matter more than fine particle engineering, those are meaningful advantages. 

4. High-concentrate permeate 

Whey permeate is a classic lower-value dairy co-product. The economics are tight, and making the numbers work usually means pushing solids as high as possible before spray drying. Standard practice concentrates permeate until it behaves almost like wet sand, which is where many atomization approaches start to struggle. 

With the ThermaShear Nozzle, you can handle higher-viscosity feeds than typical high-pressure nozzles allow, which means you can target higher upstream solids, for example moving from roughly 50–55% toward 60–70%, depending on the product and system design. Because spray drying is the least efficient way to remove water, shifting more of that work into earlier, cheaper evaporation improves overall energy efficiency, dryer sizing and capital cost, and operating cost per unit of finished product. For permeate, small efficiency gains add up fast on the bottom line. 

5. Wastewater and sludge-type streams 

Many processors face the same problem: turn a wastewater or sludge stream into a manageable solid. The typical approach is to concentrate the waste in an evaporator, send the concentrate to a spray dryer, and produce a dry material suitable for disposal or downstream use. 

These products are usually cost centers, not profit centers. In that context, the ThermaShear Nozzle offers the ability to handle thick, difficult feeds, high evaporation capacity in a compact system, and a simpler pumping setup with lower capital and maintenance demands. It's a straightforward, dependable option where reliability matters more than fine powder customization. 

Retrofit vs. new-system opportunities 

Retrofits. In the right scenario, an existing tall-form dryer can be upgraded with the ThermaShear Nozzle to unlock more capacity on established products. The key questions: 

• Can downstream conveying, packaging, and dust collection handle higher powder throughput? 

• Is the exhaust system and ductwork ready for higher dew points, so condensation doesn't become a hygiene or reliability issue? 

• Do we need changes to insulation or conditioning air to keep surfaces above dew point and prevent buildup? 

  
  

Where those items are addressed, the ThermaShear Nozzle can deliver significant capacity gains without replacing the chamber. 

New systems. The largest opportunity may be in new, low-profile systems designed around the ThermaShear Nozzle from day one. Dryer geometry, airflow, and exhaust can be optimized for high-temperature, lower-airflow operation; NFPA-compliant design and modern hygienic practices can be built in from the start; and plants get compact, practical equipment that fits their real constraints. This part of the market is often underserved, with most suppliers focused on tall-form towers and standardized configurations. Dahmes sees real value in purpose-built, compact solutions for challenging products and facilities. 

When the ThermaShear Nozzle is the right tool 

It's a strong fit when: 

• Product value is moderate to low, and extreme flexibility isn't required 

• Feeds are viscous, chunky, or abrasive 

• You need more capacity within an existing footprint 

• You want to push more water removal upstream and let the spray dryer handle less of the work 

• A straightforward, repeatable, dependable powder is the goal 

  
  

It's less ideal when: 

• You're producing high-value powders with tight particle-size and structure requirements 

• You need wide turndown flexibility or frequent recipe changeovers 

• Agglomeration, instantization, or specialized powder engineering are central to the product 

  
  

Proving it on your product 

We don't expect anyone to reconfigure a plant on a concept alone. The next step is simple: 

• Bring your product to the Dahmes R&D Center: breaker eggs, permeate, meat, wastewater, or whatever else is challenging your current setup or sitting in your development pipeline. 

• We'll run it on the ThermaShear Nozzle under realistic conditions. 

• Together we'll review capacity, dew-point behavior, energy implications, powder characteristics, and what it would take to put the technology to work in your facility. 

  
  

At Dahmes, technology only matters if it works every day in your plant, with your crew, on your schedule.
