Abstract

Malaysia being situated near the equator receives abundant solar radiation and having characterized by an average daily solar radiation of about 500-700W/m2. This could be contributed as energy sources for drying green tea. This paper present the experimental studies conducted on the herbal tea or green tea using a solar assisted drying system. The drying system has an array of collector with the size 13.8 m2. It is located at the Solar Energy Research Park, Universiti Kebangsaan Malaysia. The fresh tealeaves form the plantations are first soaked I warm water for five minutes. Next, Water from the tealeaves will be drained out and dried in the chamber. The collector is of the V-Groove type. The system has two fans to circulate air. A 10 kW auxiliary heater is also included and will be on if the temperature of the drying chamber is less than the specified preset temperature of 50°C. A drying chamber of 55°C can be reached at solar radiation levels of 600-700 Wm2 and ambient temperature of 27-34°C. The flow rate is fixed at 15.1 m3/min. The initial moisture content is 87% (wet basis) and the final moisture content is 54% (wet basis). A total of 12 hours of drying time is required where solar energy contribute about 56% the total energy requirement.
