Techno-Economic Assessment of Ginger Drying for Essential Oil Extraction by Using Infrared Technique

摘要

This paper presents technique and economical comparative analysis of ginger drying between infrared and HAD. A technique of ginger drying was studied the kinetic of drying and the electrical energy consumption in each levels of the temperature dryer at 50°C, 60°C and 70°C. In the other parts, the quality of ginger drying was studied by HPLC technique to analysis an important substance volume of ginger drying. The experimental studying on quality of this research was found that the optimal temperature of ginger drying with Infrared as 60°C had an important substance volume, gingerol-6 and shogaol-6 was 56.56%, gingerol-8 and shogaol-8 was 24.52% and gingerol-10 and shogaol-10 was 18.74%. Also, we could be saved energy 7.69 kWh. Finally, economical calculations indicated that the payback period of the infrared drying is 0.34 years.
