Synergistic intermittent heating and energy intensification of scale-up parameters in an optimized microwave extraction process

The most daunting challenge in microwave extraction is the variability in the output quality due to inherent uncontrollable temperature factors. This study focused on how to optimize the energy absorption and reduce the effects of temperature fluctuations on extracts quality in microwave extraction...
