A worrying problem in most of the cattle growing regions in developing countries is the dry season,
which reduce the forage availability and produce economical losses for the cattlemen. In order to
reduce this problem, an extruder was designed. This equipment produces briquettes from crop
residues just in the end of harvest season. So, the densified feed or briquettes can be stored and
handled wisely. This way, the animals can be fed in dry season hence reducing the problem of
losses in the small farms.
The extruder capacity is 400 kg per hour and 20.5 kW of power consumption. It is driven by
agricultural tractors of category II of ASAE standard S217.10. The density of the briquettes was
measured among 821 to 911 kg/m3 and the preliminary test of durability showed durability rating of
81%.
