Wobil Technologies has developed a Multi-Stage Rice Thresher, a climate-smart, farmer-centered innovation designed to significantly reduce post-harvest losses among smallholder rice farmers in Ghana. Field research conducted in 2021 in the Adansi South District revealed that farmers lose up to 46.05% of their harvested rice due to delayed and inefficient manual threshing, often exacerbated by exposure to adverse weather conditions such as rainfall, excessive heat, and humidity.

The innovation addresses this critical challenge by enabling rapid, efficient threshing within the optimal three-day post-harvest window, while maintaining grain integrity with less than 0.3% breakage. The machine integrates hybrid-powered systems, including solar energy, and advanced winnowing mechanisms to improve productivity, reduce labor intensity, and enhance grain quality.

Through flexible business models such as pay-per-use services, cooperative leasing, and direct sales, the solution ensures accessibility and affordability for smallholder farmers. To date, the technology has served over 898 farmers and processed more than 993 metric tonnes of rice, demonstrating strong field validation, market acceptance, and measurable impact on farmer incomes and food system resilience.

Overall, this research highlights a scalable, climate-smart mechanization approach that strengthens Ghana’s rice value chain by reducing losses, improving quality, and supporting inclusive agricultural growth.
