The Tri-Phase Difference
Tri-Phase Drying Technologies offers significant energy savings of 25 to 75% when compared to traditional forms of drying. Retrofit your existing dryer or purchase a new Tri-Phase II Dryer to attain the low heat duty of 500-600 Btu per pound of water evaporated. The Open Cycle Drying Option offers low temperature exhaust air with low concentration of volatiles and odors. The Closed Cycle Drying Option offers no air emissions, improved aroma and fuel value of products such as wood pellets. The low temperature drying option ensures maximum product quality and no “bake on” to equipment surfaces.

Material Characteristics
- Materials that require product temperatures less than 210F to maintain quality
Typical End Use Applications
- extruded food/feed products
- aquatic foods
- pet foods
- snack foods
- textured soy protein
- seeds
- grains
- oil seeds (soy, canola, rape)
- popcorn
- rice
- wood and biomass chips and pellets
- sawdust
The Tri-Phase process also technically works well for applications where the product temperature is commonly allowed to exceed 210 degree F (100 degree C);
The Tri-Phase process may be adapted to fit a wide variety of drying configurations such as belt conveyor, rotary drum, hopper/column, fluidized bed, vertical cascade, multi-tray types, and others.
