Abstract

This research is to study on the kinetics of drying and electrical energy consumption of aloe vera dried by far-infrared radiation (FIR) combined with hot air (HA) technique. The experiment conditions of aloe vera   (Aloe Barbadensis Mill.) drying were set up a velocity of 0.6 m/s, drying temperature at 50, 60 and 70 C, initial moisture of 98 % w.b. and final moisture of 5 % w.b. The results found that drying temperature increased could reduce the moisture content and drying time of dried aloe vera. The optimization condition of dried aloe vera by FIR combined with HA was aloe vera dried by drying temperature at 70 C which had drying time of 170 minutes, electrical energy consumption of 1.12 kWh and specific energy consumption of evaporation of 45.891 MJ/kgwater.
