Abstract

This research has purposes to design and analyze for comparing performance of sun-drying oven by using a sun thermal collector having 76.23% heat absorption. We use 180 Lt. of a 3GS hot oil and       80 kg of Ø20-30 mm ball granite filled in an insulated cylindrical tank for our heat storage system.

To evaluate our system, 1000 kg of seasoning beef was put in 2-storey drying oven for 24 hrs. Temperature was recorded every 1 hr. and found that it is approximately 40-65.5C. The highest performance is 68.36% whereas the flow rate of the old is 8Lt/min. At the end of drying process, we found that humidity of the beef is only 6.25% wb. Comparing to non-storage drying system which only working during the day, our system can be used as dryer for 24 hrs. From economical point of view, the investment return point is around 2.9 years.
