| Abstract | ||
| The study was carried out to test and evaluate using of Microwave for drying the chamomile flowers and rosemary plants. The experimental treatments included three different levels microwave power (450, 720, and 900Watt), three different load (1.5, 3.0, and 4.5 kg/m²). The drying behavior was simulated using two different models (Lewis and Henderson Pabis). The studied models were compared for fitting the obtained drying data and the most suitable model for predicting the moisture content chamomile and rosemary 78%, and 65% during the drying process was assessed. Final quality of both the dried chamomile and rosemary plants were also determined. The results show that, both studied models could describe the drying behavior of chamomile and rosemary satisfactorily. However, the Lewis model considered more proper for describing the drying behavior and predicting the changes in moisture content in terms of precision and application simplicity. The quality tests of chamomile and rosemary plants dried showed that, microwave power of (900 W) and (720W) with load of 3.0 kg/m² recorded the best quality for dried chamomile and rosemary respectively, in terms of the highest percent of volatile oil and compound oil. | ||
