Aspects regarding the design of equipment and monitoring of the parameters that affect the drying and fighting process against insects and pathogen factors in microwave field

This paper deals with numerical computation of high frequency electromagnetic field for an industrial mixed microwave and hot air spurt drying system. Finite element method employing 3d elements is used to solve the complex electromagnetic problem. The paper will review some recent results using finite elements in the quest to acquire informed design knowledge in some of these processes, where possible validation with other numerical techniques or by thermal imaging will also be presented.
