Title : Testing and evaluation of Mini SRR Dryer in Nepal for rice crop Material Type: printed text Authors: G.B Manandhar, Author ; Rabi Rasaily, Author ; Shrestha, G.L., Author ; R.R Bakker, Author Pagination: 19-27 p. Languages : English (eng) Keywords: Drying air temperature, drying cost, rate, moisture content, payback period Abstract: Mini SRR rice seed dryer received from IRRI consisted of a cylindrical bin, an electric blower (2.5”, 320 watt) with a cylindrical support, a rice husk stove and a metallic pipe. Eight tests were conducted during rainy weeks of Ju ly ,2002 three at Kavre Palanchowk, four at Dhanusha and one at Parsa district Grain loaded varied from 145 to 175 kg with moisture content (MC) from 17.8 to 23.5%. Overall drying rate with rice husk as source of heat was found to be 0.45% MC/hour, which is much higher, compared to results of Vietnamese SRR-1 dryer with electricity as heat source. Extrapolation to 13% final MC by simple linear regression showed an association with one another in a linear way (r = 0.83). With 250 kg loading, drying cost for one ton rice was found to be Rs476 for IRRI dryer but in replicated dryer without heat insulation on metal pipe, it was found to be Rs874 due to lower blower RPM. However, computations show that even cost of replicated dryer would be paid back within 10 years with 35 days of operation per year. It showed the possibility of commercializing t he dryer for the small farmers either for seed or for food grain purpose. Maximum thermal efficiency of 22.4% was obtained at 0.6 kg rice husk/hour and 44.7°C drying air temperature (DAT). With DAT from 44.7°C to 49.0°C at Kavre germination rate of paddy varied from 77-88%. The study, also aimed a t enhancing the coverage of early rice in the country, has shown encouraging result.
