Thermal processing is vital in food, pharma, chemical, biomass, cannabis, hemp, and mineral applications, relying on direct or indirect heating methods to change the temperature of a material and alter its state in some way. In many thermal process applications, the drying technology must be extremely precise, and Marion solutions offer uniform heat generation and the ability to efficiently control the operating temperature and moisture content. Tap into our expertise and learn more about the various advantages and disadvantages of different thermal technologies in our Thermal Processing Handbook.

WaveMix: Combining Waves with Motion




In both direct and indirect thermal technology, achieving consistent drying output is essential. For that reason, mixing during the drying process provides a significantly superior outcome. Not only does mixing provide even drying throughout the mix, but it also can speed mixing times. Marion has leveraged its mixing expertise in conjunction with its microwave dryer. We call it WaveMix™.

WaveMix represents the new wave in thermal processing technology that combines microwave, vacuum and mixing. Wavemix unlocks your potential by using microwave energy to generate returns in your application. Our insight has proven that an agitated bed of material is key to industrial microwave processing of powders, granulars and slurries. No hot spots. No long waits. In short, no worries.

Microwave heating of a fluid bed of product creates the advantage of shorter processing time, uniform material temperature (no scorching), and the flexibility to operate under pressure, vacuum and/or nitrogen blanket.

Comparison of WaveMix to other thermal processing methods

WaveMix™ was designed to address the market demands for fast, accurate and sanitary drying and mixing. As compared with indirect heating methods, microwave drying offers the following benefits.


  • Time savings: WaveMix reduces the drying times compared to other thermal processing methods.
  • Repeatable results: By creating a fluidized bed through mechanical agitation, the materials are exposed to even heat distribution.
  • Precise control: Temperature is measured at multiple locations in the vessel allowing for real-time adjustment through the process.
  • Moisture content management: By managing the heating profile, the moisture content can be effectively controlled.
  • Energy optimization: Compared to indirect drying, WaveMix uses less energy because of the faster processing times.
  • Unmatched versatility: With the ability to control the boiling point of materials and heat moment-by-moment, WaveMix places the operator in full control of the application where indirect dryers fall short.
  • No case hardening: While indirect heating methods can cause the outer surface of a particle to be harder than the internal consistency, microwave processing eliminates this problem.
  • Eliminate material loss: Tight control removes the opportunity for batches to be ruined due to burning, overcooking or undercooking.
  • Quality results: WaveMix™ maintains flavor, color and other desirable characteristics of the materials being processed.
  • Safety: People and other equipment are in a safe operating environment due to the low external machine temperature, and the numerous radio frequency safeguards.
  • Gentle processing: Being able to precisely control temperature and agitation allows the handling of delicate, thermolabile, crystalized, nano and other types of sensitive materials.
  • Small and trial batches: WaveMix™ Mini can be utilized for laboratory testing, R&D and small batch processing.
  • Flexibility: The WaveMix™ technology is appropriate for materials that are neither perfect electrical conductors nor perfect electrical insulators.

One of the most common applications for the WaveMix is in working with foods, because of the need to retain the taste, smell and nutritional value of food products. In the next section, we go deeper into the specifics of why food processors are increasingly adopting microwave mixers and microwave drying technology.

Microwave dryer for food

The combination of a microwave mixer and microwave dryer provides particularly high value in the processing of precision mixes, such as in food processing, pharmaceuticals, nutraceuticals and chemicals of a variety of types. Microwave is also appropriate for powder drying for anything from chemicals to powdered metals and consumables. Unlike indirect thermal technology, microwave is a direct thermal processing methodology that provides a level of precision that is simply impossible with indirect dryers.


What makes WaveMix unique is the ability to process heat-sensitive products. For example, when it comes to food, excess heat can cause deterioration in the nutritional value, color and aroma of the products. Dried fruits and vegetables processed through a microwave dryer with vacuum retain a superior flavor, aroma and color compared to other drying methods. The reason is simple: vacuum allows the reduction of the boiling point and the microwave provides direct heat.

Superior quality is just one reason to use microwave mixing and microwave thermal processing for food products. Another essential ingredient is ensuring pristine sanitation of the machines. Violation of sanitary standards is expensive. The average cost of a recall to a food company is $10 million in direct costs, according to a joint industry study by the Food Marketing Institute and the Grocery Manufacturers Association. For that reason, when working with food, it’s important to make sure that mixing and drying equipment maintains 3-A Authorization. Meeting sanitary requirements also means that it’s faster and easier for staff to clean a WaveMix system. Some kinds of powder mixing leave a residue that is hardly visible, but with the right equipment, you can easily clean and maintain safety standards, providing a product that is safe for human consumption. Microwave is also extremely effective in eliminating any bacterial contamination with the direct heating methodology.

Microwave mixing and powder drying

In addition to foods, powders are another application where WaveMix provides results that had been impossible with other drying technology, reaching much lower moisture levels without degrading the quality of heat-sensitive material. In the chemical, biomass and pharmaceutical industries, processors are finding they can create new formulations with the help of this breakthrough technology.

When it comes to working with powders, mixing and drying together saves time and creates more consistent mixes for pharmaceutical, nutraceutical and chemical applications. Powder drying with microwave offers a high level of flexibility in mixing and drying a variety of powders for the consumer market.
