| Abstract | Solar-biomass drying system is designed and constructed to dry 100 para rubber sheets having 135.6 kg total weight. The flat plate solar collector with area of 48 m2 is used to provide heat for drying system from 9:00 to 17:00. After 17:00 to 9:00, firewood combustion in the biomass burner is employed to supply heat. The dimensions of the biomass burner are 1.0 ? 1.0 ? 1.2 m. Experimental results showed that drying with solar and biomass takes 53 hours and the final moisture content of para rubber sheet was quite constant at 1.2%db after 39 hours drying. The average drying temperature was 48.2 OC and the drying rate was 0.3 kg-water evaporated/hour. Additionally, the comparison among different drying techniques like sun exposure, smoked type and solar-biomass in terms of drying quality, cost per dried sheet and total drying time are presented. It can be concluded that para rubber sheet dried by using solar-biomass hybrid system yields the best quality, low cost per dried sheet and short drying time. |
