Abstract
Mechanical intervention in each stage of post-harvest rice processing is essential to reduce cost and minimize post-harvest loss. Drying is an important post-harvest operation for long term storage, maintaining rice quality and reducing postharvest loss. BAU-STR was tested at the Department of Farm Power & Machinery, Bangladesh Agricultural University, Mymensingh during Boro and Aman 2015 harvesting seasons to understand the effectiveness and potential of using at farmers’ level as an alternative to sun drying. The temperature profile of the dryer proved that hot air temperature uniformly distributed throughout the dryer, and also the rough rice dried uniformly and reached at desired level of moisture content within 4 to 5 hours. The moisture removal rate was 2.4 and 2.0 %hr-1 during Boro and Aman season, respectively. The drying efficiency was found 55.3 and 48.6% during Boro and Aman season, respectively. The milling recovery was found more in BAU-STR (73.0±1.3%) compared to the sundried rough rice sample. Head rice yield was found 66.9% for BAU-STR and 63.9% for the sundry method. The germination rate was above 80% in both seasons for BAU-STR and sundried method. The drying cost of paddy was found Tk. 0.87 kg-1 and Tk. 0.74-1 for diesel and electricity operated dryer, respectively. In terms, benefit-cost ratio and payback period BAU-STR dryer are recommended for drying of rough rice at the farm level. The dryer could be used successfully as cost saving and user friendly technology to eliminate drying problems in the rural area of Bangladesh.
Key Words: BAU-STR dryer, Drying rate, Drying efficiency and Rough rice
