Modeling of Susceptor Assisted Microwave Heating in Domestic Ovens
Susceptors are used in microwavable food packages to facilitate preferential heating. Modeling of susceptor assisted microwave heating in domestic ovens was performed using radio frequency and heat transfer modules of COMSOL Multiphysics 4.2. Two different approaches (domain discretization and transient boundary condition) were studied for taking into the account of discretizing thin susceptor ...
متن کاملHeating Performance Assessment of Domestic Microwave Ovens
Due to inherent nature of standing wave patterns of microwaves inside a cavity and dielectric properties of different components in a food, microwave heating leaves non-uniform distribution of energy inside the food volumetrically. Achieving heating uniformity plays critical role in improving the safety of microwave heated products. In this paper, we present a method for assessing heating unifo...
متن کاملFrequency Distribution in Domestic Microwave Ovens and Its Influence on Heating Pattern.
In this study, snapshots of operating frequency profiles of domestic microwave ovens were collected to reveal the extent of microwave frequency variations under different operation conditions. A computer simulation model was developed based on the finite difference time domain method to analyze the influence of the shifting frequency on heating patterns of foods in a microwave oven. The results...
متن کاملApplication Study of New Solid-State High-Power Microwave Sources for Efficiency Improvement of Commercial Domestic Ovens
The work is concerned with an emerging technology of microwave ovens fed by several independently controlled solid state power sources. Its advantages are summarized and a computational method for adjusting individual amplitudes, positions, and relative phases of the multiple sources is presented in general terms. While mathematical details will be published elsewhere, here for the first time t...
متن کاملOne dimensional models for the microwave heating of moist foodstuffs
Microwave ovens are frequently used in domestic situations for the heating of chilled foodstuffs which are generally approximately 80% by weight water. Rapid, internal heating are some of the key benefits over conventional ovens. The food industry utilises these attributes in a number of ways most in particular with the introduction of microwave ready meals and convenience food. It is important...
