Abstract

This study is conducted to analyze the drying characteristics of domestically produced Lycii Fructus for improving drying conditions which was dependant on the shape and materials of drying plate. The materials of the drying plates were steel, aluminum and ABS resin, and each plate was shaped semicircle, quadrangular pyramid, and triangle pyramid. Also, mesh plate, the most general type was included. In other words, 10 kinds of plates were made and tested. The test was conducted at $45^{\circ}C$, for 24 hours and moisture content was measured every 4 hours. The quality of tested Lycii Fructus was measured by colorimeter after drying. The experimental results show that regardless of species of Lycii Fructus, the drying rate of the aluminium plate shaped quadrangular pyramid was fastest, 3.11%w.b./h. Except the mesh plate, the drying rate of most plates was about over 2.52%w.b./h. The quality of Lycii Fructus dried on the aluminium plate shaped quadrangular pyramid was the highest, and it was easiest to separate the dried Lycii Fructus from the aluminum plate shaped quadrangular pyramid.
