The drying of paddy in Sub-Sahara Africa is mostly by sun-drying. This is done rudimentarily by spreading the paddy on nylon woven bags stitched together to produce a drying mat or tarpaulin placed directly on the ground. Most of the nylon and tarpaulin bags have holes through which grains can drop. There was no control for moisture during drying and mixing is done by scattering the paddy with hands or feet while walking on it. This results in high postharvest loss. An improved sun-drying method is being promoted by AfricaRice where the paddy is uniformly spread (2 to 4 cm thick) on a tarpaulin placed on a cemented surface enclosed by a fence. The paddy is mixed 1-2 times every 30 min using a plastic rake to ensure uniformity in moisture loss during drying. When the moisture was 16%, the paddy is collected in bags and store for three days. After this period, the drying process is continued to a moisture of 14% and the paddy weighed before milling. In the humid agroecological zones in the continent, sun-drying of paddy is not possible during the wet season. Other drying options such as the husk fuelled flatbed dryer and the GrainSafe are being evaluated at AfricaRice as possible solutions to paddy drying challenges in the humid zones of Africa.
