Study and design of a poultry feed crusher-calibrator

This work focuses on improving the technical and economic performance of the poultry farming sub-sector in Benin. We were specifically interested in the study and design of a grinder-grader for poultry feed. Indeed, two different technologies for controlling the particle size are combined into one to form the crusher-sizer. This is the fragmentation of food particles, carried out by the mobile hammer mill and the dimensional classification carried out by a vibrating sieve or sizer. These two technologies are well developed in industries, especially in quarries, but their applications in the field of agro-food processing in Benin are rare or practically non-existent. This technology will allow an increase in the production time and cost of poultry feed. The grinder-grader is then a new technology, a new piece of equipment designed with the aim of allowing poultry farms in general and traditional poultry farmers in particular, the self-production of poultry feed. It is then that they will be able to efficiently minimize the time and cost of poultry production to finally optimize the economic performance of farms.
