Computational Modeling Tools to Enhance Development
of Microwave and Radio-Frequencies Processes
for Microbial and Pest Control

Problem Addressed

The proposed research will develop an integrated computational model for prediction of electromagnetic field and thermal phenomena associated with heating processes of microwave and radio frequencies (RF). The model will have the flexibility for use in developing radio frequency and microwave based systems and processes for sterilizing or pasteurizing packaged foods and for developing thermal treatments for post-harvest pest control in agricultural commodities.

Goal

Application of computational electromagnetics and heat transfer to study microwave heating process for food sterilization.

Implications

• The process will positively influence the multi-billion dollar thermal processing industry in the PNW and US.
• New technologies developed with the support of the computation models will add value to commodities and to the competitiveness of the agricultural and fish products produced and harvested in Washington and PNW.
• The numerical methods used to develop the model are uniquely suited for simulation of microwave food processing systems.
