Performance of Solar Drying System with Rotating Rack for Malaysian Red Chili (Chili Bangi)

摘要

This paper presents the performance of solar drying for Malaysian red chili (Capsicum annuum L.) as known chili bangi. The red chili is dried from moisture content of about 80% (wet basis) to 10% (wet basis) in 31 h (daytime drying). It was compared with open sun drying, which for open sun drying of 65h obtained. However, saving in drying time of 49% for solar drying over open sun drying obtained. Also at average solar radiation of 420 W/m~2 and air flow rate 0.07kg/s, the collector, drying system and pick-up efficiencies were found about 28%, 13% and 45%, respectively.
