INOVASI PENGERINGAN BUNGA ROSELLA RAMAH LINGKUNGAN: PEMANFAATAN TEKNOLOGI SOLAR FOOD HYDRATOR

Abstract

One of the most abundant commodities in Selopanggung village, Kediri Regency, is the rosella flower. Rosella flowers have numerous benefits when processed. However, the processing of rosella flowers in the community still uses conventional methods. The drying process is ineffective because it requires a lot of time and labor. This condition indicates that conventional drying can reduce the quality of rosella flowers. A drying machine with solar food dehydrator technology is one of the tools that can be used to produce high-quality rosella flowers. Drying at a temperature of 70℃ is the most effective type, resulting in the lowest final mass and a high heat transfer rate. The appropriate drying time for rosella flowers, resulting in a final mass of 0.205-0.152 kg with a final mass percentage of 15%, shows that the drying rate achieved is 1,33 10^-4 kg/m².h at a temperature of 70℃ and 1,25 10^-4 kg/m².h at a temperature of 65℃.
