Title : Development and testing of low cost solar dryer for drying agriculture commodities Material Type: printed text Authors: Shreemat Shrestha, Author ; Rabi G. Rasaily, Author Pagination: 11-14 p. Languages : English (eng) Keywords: Low cost mud dryer, mushroom drying, solar dryer Abstract: Open solar drying has been traditionally practiced in drying agricultural commodities in Nepal. Open sun drying are prone to the contamination of dust, insects etc. To address these problems, different types of cabinet type solar dryers are developed but are not adopted by Nepalese farmers due to high cost and unavailability of the construction materials in the remote areas. To overcome these problems the low cost solar dryer was developed and comparative testing of it with wooden and metallic (galvanized sheet (GI) sheet fabricated) solar dryer was performed for mushroom drying in Agricultural Engineering Division (AED), Khumaltar. The new model of low cost solar dryer is constructed by using the local construction material mud brick/ stone mud mortar and can be constructed of different size according to the requirement of the farmer. Only the external material used is transparent ultra violet (UV) protected polythene sheet, black board paint and GI net The cost of low cost solar dryer of size 0.8- x I ..S-m is about Rs500 where the wooden and metallic solar dryer of similar size costs about Rs2500 and 6000 respectively. The capacity of the low cost solar dryer of size 0.8- x 1.5-m is of 3 kg of mushroom drying per batch. The duration of drying of mushroom to MC level below I0% is attained within 2 days of drying. The moisture curve of the mushroom in the low cost solar dryer, metallic dryer and the wooden dryer indicated that there is no significant difference at high and low moisture level. The temperature curve of the solar dryers indicated that the rate of increase of temperature of mud dryer is less in the initial 2 hours and after this, it is found to be more than the wooden dryer. The low cost solar dryer can be one of the appropriate options in drying the agricultural commodities in the remote areas due to its performance comparable with the modem solar dryers, and low cost of construction.

Title : Improved tubular corn sheller: Appropriate drudgery reducing agricultural equipment for maize growers Material Type: printed text Authors: Shrestha, K.B., Author ; Adhikary, S.K., Author ; Rabi G. Rasaily, Author ; Shrestha, G.L., Author Pagination: 15-18 p. Languages : English (eng) Keywords: Corn sheller, drudgery reduction, rural comnmunity, equipment Abstract: Shelling corn or maize is, in general, the responsibility of the farming woman, whether child, youth or aged. The corn shelling operation is usually carried out manually and hence, a tedious job. It consumes a lot of time, labor and energy of the women force in agriculture. Relieving these agricultural women workers from such drudgery is a major challenge for researchers and development workers in the country. Though some farmers in the country use manual corn sheller developed by Agricultural Tools Factory (ATF) at Birgunj or Development Consulting Services (DCS) at Butwal to some extent, but access to such modern corn-shelling device is beyond the imagination for the majority of the women from the rural sector. Realizing the drudgery of the rural farming community, scientists at Agricultural Engineering Division (AED) under NARC have developed different prototypes of improved tubular corn sheller including manual as well as pedal operated equipment. Various prototypes of both manual and pedal operated corn shellers were designed, fabricated and tested by the researchers at the AED. These AED prototypes of the manual corn shellers are the improved version of the lnternational Rice Research Institute (IRRI) design, while the design or the pedal corn sheller is of the AED itself During performance testing of the manual corn sheller, the shelling capacity and the efficiency were found to be 13.8 kg/h (146 cobs/hr) and 94.6% respectively at 9.2% moisture content of maize kernels. Similarly, in case or pedal operated tubular corn sheller, the shelling capacity of 27.9 kp/hr (318 cobs/hr) and the shelling efficiency of 93.1% were obtained at maize kernel moisture content of 12.7%. The shelling capacity of pedal corn sheller was 102% more than that of manual corn sheller.
