SIL Fab

Multi-Crop Thresher Fabrication Training

Background

The Feed the Future Innovation Lab for Soybean Value Chain Research (SIL) is dedicated to soybean research for economic development and the reduction of poverty and hunger by nurturing improved soybean value chains in Africa. A shared commitment to reduce quality and quantity losses associated with poor threshing is the basis of an ongoing partnership between SIL and ADMI.

Project Information

Soybean threshing remains one of the larger bottlenecks for improving productivity among soybean producers. The lack of access to mechanical threshing reduces planted hectares because of the extensive labor demands of threshing at harvest. It also reduces seed quality and germination levels among seed producers. In addition, farmers receive lower sale prices when poor threshing results in poor grain quality.

To address the thresher bottleneck, SIL has worked with manufacturers in multiple African countries since 2016 to develop low cost, locally produced, medium-scale multi-crop threshers that can shell maize and thresh soybean, rice, beans, sorghum, and other crops. The threshers have been under continuous improvement through testing, redesign, and direct engagement between engineers, fabricators, and users. In 2018, after two years of research and development, the thresher went fully commercial with sales in northern Ghana.

Objectives

With funds from ADMI through the ADM Cares program, SIL received a grant to support multi-crop thresher trainings in four African countries: Ethiopia, Kenya, Nigeria, and Zimbabwe.

Outcome & Results

The Soybean Innovation Lab mechanization team led by Dr. Kerry Clark trained 26 local equipment manufacturers and educators in thresher fabrication at the Wolkite Polytechnic School in Wolkite, Ethiopia, from November 18-25, 2019. The training was organized by the Ethiopian Emerging Technology Center(EETC), a division of the Ethiopian Biotechnology Institute (EBTI). The training program included a seminar involving all participants and interested parties including funders, local NGOs, USAID, media, Government of Ethiopia officials, agro-businesses, and farmer groups. The seminar provided a platform to inform the public of the capacity of Ethiopian businesses to provide thresher fabrication services. SIL conducted a similar thresher fabrication training in Harare, Zimbabwe in March 15-23, 2020. This workshop included train-the-trainer elements and was conducted in coordination with the International Maize and Wheat Improvement Center (CIMMYT), which was invited to suggest commercial fabricators for the workshop. ADM Cares financed the SIL trainers at this event and the materials used for one of the three threshers constructed. CIMMYT received the thresher produced with ADM Cares funds so the international organization could utilize and demonstrate it for farmers.

Trainings in Nigeria and Kenya aredelayed due to COVID-19.
