“…These results are in agreement with those reported by Blanco, Ming, Marques, & Bovi (2002b) in peppermint (Mentha piperita L.) and by Blanco, Marques, Ming, & Bovi (2002a) in rosemary (Rosmarinus officinalis L.). In the same way, Buggle, Ming, Furtado, Rocha, and Marques (1999) found that increasing temperature from 30 to 90°C resulted in a decrease in EO content of Cymbopogon citrates. Similar results were also found by Khangholi and Rezaeinodehi (2008) in sweet wormwood (Artemisia annua) from Iran.…”

“…They noted the works of Buggle et al. () who dried lemongrass leaves at 30–90°C and found that the highest oil content of 1.43% was found in leaves dried at 50°C. Drying at 30°C favored fungal growth and drying at 70°C resulted in significant reduction in essential oil content to 0.34%.…”

“…With respect to the effect of air velocity on quality of dried leaves, Coradi et al (2014) found that increasing the air velocity from 0.8 to 1.3 m/s did not negatively affect the essential oil content of lemongrass leaves when compared with fresh leaves; however, further increasing the velocity to 1.8 m/s resulted in a statistically significant reduction in oil content. They noted the works of Buggle et al (1999) who dried lemongrass leaves at 30-90°C and found that the highest oil content of 1.43% was found in leaves dried at 50°C.

The objectives of this study were to investigate the effect of temperature (40, 50, 60, and 70°C), and air velocity (0.5, 1, and 2 m/s) on the drying behavior of West Indian lemongrass (Cymbopogan citratus) leaves. Drying was carried out in a computer‐controlled tray dryer. Overall, the effect of temperature was seen to be more important than that of air velocity, but the air velocity did have an effect on drying rates at the start of the drying process at 50–70°C. Drying rate constants, diffusivity values, and activation energy were determined. Twenty‐two empirical and semiempirical thin‐layer models were tested, and although model fit varied, the Midilli model could be applied to all data with reasonable prediction of MR values.

“…); however, when the drying plant has a temperature of 40 °C, the oil content was reduced to 0.89% (db). Buggle et al (1999) carried out the drying of lemon grass in an oven heated to 30, 50, 70 and 90 °C to constant weight to evaluate the quantity and quality of essential oil. The best results were obtained for the essential oil content by drying at 50 °C (1.43%); although the treatment at 30 °C (1.34%) showed significant difference with 50 °C it is not indicated, because it favored fungus growth.…”

The aim of this study was evaluate the drying of the lemon grass plant (Cymbopogon citratus Stapf) at different air temperatures (40 °C, 50 °C, 60 °C and 70 °C) to adjust the experimental data obtained with different mathematical models and assess the quality of the plant after drying. A completely randomized design (CRD) was used with three drying replications for each speed and temperature of the drying air. The essential oil content extracted from the dried plant at 0.8 m s -1 and 1.3 m s -1 with manual control system was not affected by the drying process; the temperature of the drying air had a negative influence on the levels of the essential oil of the plant; drying with automatic control decreased the essential oil content for all velocities studied compared to the fresh plant; increments in the temperature of the drying air significantly reduced drying time. The mathematical model of Two Terms is adequate to describe the drying process of lemon grass plant (Cymbopogon citratus Stapf); diffusion values increased with increasing temperature of the drying air, while the value of activation energy was 62.84 kJ mol -1 .Key words: air, control, plant, velocity, temperature.
