Post-harvest activities in Bangladesh are traditional and labour intensive. The main activities are manual harvesting, manual threshing, animal or mechanical treading, sun drying, traditional parboiling and milling in huller mills or traditional devices. The milling recovery and quality of milled rice depends on the milling machinery, pre-milling treatments and the paddy variety. Many of the post-harvest activities in the rural area are done by women. These activities are mainly threshing, cleaning, drying, parboiling, milling and grading. The post-harvest losses in paddy are estimated at about 13% of which the processing losses are very high. The losses are due to delayed harvesting, improper handling, incomplete threshing, scattering, bird and domestic animals eating the grains, improper soaking, parboiling and drying, and the use of inefficient steel huller for both husking and polishing. There is no organized rice marketing system in the country. As a result, the farmers receive low prices f

or their paddy. Millers, traders or enterprises are not accountable for the quality of the polished rice in the market. Improved methods for loss prevention are suggested in this paper. The practice of steam parboiling in all the rice mills will produce uniform parboiled paddy. The rubber-roll huller for husking can be incorporated with the existing machinery and used as a polisher. The owners of automatic rice mills can take out loans to run the mills. Some action programmes are suggested for the adoption of appropriate post-harvest technology and the improvement of rice processing and marketing.
