This demonstration activity was conducted with the objectives of enhancing farmers’ awareness of the importance and use of the powered grain de-huller machine, evaluating the performance of the powered grain de-huller machine under farmer’s conditions, and collecting farmer’s feedback on the machine at Munessa, Lemu Bilbilo and Adaba districts of Arsi and west Arsi zones. The demonstration site and representative farmers were selected based on location and suitability to involve more farmers in visiting the demonstration sites. Min-field day was organized to enhance farmer-to-farmer learning, information exchange, and experience sharing among Farmers and other stakeholders on technology. The training was organized on grain de-huller technology; a total of 107 participants, of which 25.2% were male and 74.8% were female, participated in both theoretical and practical training on grain de-huller technology. The training was mainly focused on how to operate technology and the relative advantage of technology over local practice, which was de-hulling grain using traditional material. The experiment was carried out to estimate the performance of the grain de-huller machine in comparison with traditional de-hulling practices. The results indicated that grain de-huller technology had a de-hulling capacity of 320kg/hr. for barley with one operator and 390kg/hr. for wheat with operator respectively. Whereas traditional grain de-hulling practices took 33kg/hr. on average with one operator for barley and 38kg/hr. for respectively wheat. This finding indicated us grain de-hulling technology had a huge advantage in terms of time minimization and quality of grain de-hulling. Therefore, livestock feed mixer technology is recommended for further scaling up and wider utilization.
