Recently, the interest in olive leaf has increased due to its high phenolic content. It a potential for industrial exploitation food industry and main process treatment is drying. Drying affects product quality an energy-intensive process, so use of heat pumps drying processes that have low operating cost attracted attention investigators. In this study, response surface methodology was used optimize conditions leaves pilot-scale pump conveyor dryer. The independent variables were air...

Abstract Since phenolic compounds have been known as strong antioxidants, studies on olive leaves attracted the investigators due to richness of in leaves. Recently, are used medicine, cosmetics, and pharmaceutical products. It has a high potential for industrial exploitation food industry. In this study, importance is briefly given, composition leaves, main phenolics their health effects described. Studies conducted technological usage reviewed. The future industry discussed. expected that...

This article deals with the exergy analysis and evaluation of broccoli in three different drying systems. The effects air temperature on destruction, efficiency, exergetic improvement potential process were investigated. destruction rate for chamber increased rise at 1.5 m/s, both tray heat pump dryer. highest efficiency value was obtained as 90.86% fluid bed dryer comparison to other two systems during 45°C velocity 1.0 m/s.

ABSTRACT Recently, interest in olive leaves has increased because of their high phenolic contents. Although the critical process leaf treatment is drying, drying behavior not been known yet literature. In this study, were dried a tray drier at temperature range 50–70C and velocity 0.5–1.5 m/s. Eleven different semitheoretical thin‐layer curve models used to characterize leaves. Effects air on model coefficients determined by multiple regression analysis. The correlation coefficient ( r ),...

Abstract In this study, white cheese powder was produced using a pilot-scale spray dryer. Drying experiments were carried out with an inlet drying air temperature range of 160–230°C, outlet 60–100°C, and atomization pressure 294.2–588.4 kPa. The performance the spray-drying process effects conditions on evaluated energetic, exergetic, exergoeconomic analyses. assessment performed by energy exergy efficiencies, improvement potential () rate, total cost, factor terms. A comprehensive...

Exergy analysis has been used as a powerful tool to study and optimize various types of energy systems. However, the methodology splitting exergy destructions (the so-called advanced analysis) allows for further understanding destruction values improve system efficiency. In this study, was applied pilot-scale heat pump drying in food first time evaluate its performance at different temperatures. The results showed that inefficiencies within compressor condenser were mainly due internal...

Abstract In this study, plum slices were dried in a heat pump dryer designed and constructed Ege University, Izmir, Turkey. Drying experiments carried out at an air temperature range of 45–55°C. The performance the along with its main components evaluated using exergy analysis method. Exergy destruction capital cost rates used for exergoeconomic analysis, which is based on quantities exergy, cost, energy, mass (EXCEM) to values R ex obtained vary between 1.668 2.063 W/USD different drying...

ABSTRACT Recently, olive leaves have a high potential for industrial exploitation in the food industry. The main process leaf treatment is drying. Because drying an energy‐intensive process, analyzing and improving systems important. In this study, were dried tray drier performance of was evaluated using energy exergy analyses methods. effects air temperature velocity on discussed. While utilization ratio values varied between 14.05% 26.21%, exergetic efficiencies 55.95% 75.12%. It inferred...
