Microwave Techniques manufactures ridged waveguide serpentine systems with patented technology for microwave drying of industrial materials. This type of system can be used to post-dry materials after a conventional dryer to optimize final moisture uniformity or purely for standalone drying. In addition, the ridged waveguide applicator technology offers an efficient solution to many challenging heating or drying processes.
Ridged Waveguide Serpentine Applicator Technology: Benefits
Our patented ridged waveguide systems and related microwave applicator technology eliminates hot spots by uniformly heating thin materials of medium to low moisture content that do not efficiently absorb energy by conventional conductive or convective heat transfer processes. Overall, benefits of this technology include:
- Increased production throughput as high speed microwave heating reduces drying times.
- Microwave energy distribution reduces risk of over-drying or scorching the product surface.
- Rapid power adjustments and on/off capabilities eliminate lengthy warm up and cool down times.
- Modular design and construction: compact footprint suitable for vertical or horizontal applications.
- Lower energy consumption than conventional dryers with products containing less than 15% moisture.
Applications
A ridged waveguide serpentine system applicator consists of a series of specially designed waveguides arranged in a serpentine pattern. Its modular construction allows an electric field orientation, parallel to the material passing either on a microwave inert belt through the applicator or directly as a substrate without a belt. The result is greater absorption of power by the material. We’ve seen success with various materials.
A range of loose granular to continuous sheet materials has been successfully heated or dried, and includes:
- Textiles
- Crumb rubber
- Medical foams
- Wood products
- Corrugated paper
- Insulation materials
- Non-woven materials
