Macrowave Radio Frequency Co.

Ultra-Series Post-Baking Dryers
for Biscuits, Crackers, and Snack Foods

Adding a Macrowave™ Dryer to a New or Existing Oven Line Increases the Line's Productivity
and its Ability to Process a Greater Range of Products

Benefits:See How they Work

  • INCREASES OVEN LINE THROUGHPUT: Product throughput on a typical oven line can be increased by 30% or more.
  • ELIMINATES CHECKING: Checking caused by the stresses of uneven product shrinkage is eliminated because of the moisture uniformity achieved.

  • PRECISE MOISTURE CONTROL: Selectively heats products where the moisture content is the highest. The product output will be uniform throughout, regardless of the non-uniformity going in.

  • IMPROVES COLOR CONTROL: Desired color can be developed in the product during baking independent of drying considerations. The Macrowave™ system then achieves the desired moisture content without affecting product color.

Advanced Features of the Ultra-Series Macrowave Dryers:

  • The low operating voltage of the 40 MHz Macrowave system increases the variety of products which can be dried by this method.
  • The latest design of PLC controls provides complete diagnostics and centralized control of all dryer functions.
  • The system can dry products downstream of an oil sprayer in bed depths of up to 6".
  • The Macrowave heat reclamation system uses waste heat from the RF power generator to scavenge moisture and increase drying efficiency.
  • Macrowave dryers conform to OSHA and FCC standards and carry the UL-approved label.
