This article presents the design, implementation and evaluation of performance tests of a motorized feed grinder-mixer made from local materials. The dynamic and dimensional study made, allowed the realization of a prototype of 350 liters in capacity. To assess the uniformity rate of the machine, three types of feed were used, namely: (1) starter, (2) chicken and (3) layer. In addition to food, the coefficient of variability between samples after chemical analysis was obtained for each chosen mixing time. The determination of the different optimal rational models of the homogeneity rate was made with Matlab R2017a to determine the minimum mixing time. The results of this study show that the machine developed allows the homogeneous mixing of 427 kg of feed per hour with a maximum energy consumption of 0.72 Wh/kg. The feed variability coefficient is less than 10% in 12 minutes of mixing, resulting in better homogeneity rates. The specific energy consumption is around 59%. This machine has low environmental pollution (little noise and dust), guaranteed ergonomics and stability; also, maintenance is easy. The estimated cost of developing the prototype is around 381,300 FCFA, or 568,00 USD; this machine is therefore accessible to average breeders. The results of this study also show that, compared to what exists on the Cameroonian market, this machine has several advantages for improving farming techniques and the living conditions of the populations.
Author Keywords: salt concentration, coefficient of variability, homogeneity rate, hourly capacity, energy consumption, animal feed.

Abstract
This article presents the design, implementation and evaluation of performance tests of a motorized feed grinder-mixer made from local materials.

To assess the uniformity rate of the machine, three types of feed were used, namely: (1) starter, (2) chicken and (3) layer. In addition to food, the coefficient of variability between samples after chemical analysis was obtained for each chosen mixing time.

Cet article présente la conception, la réalisation et l’évaluation des tests de performance d’un broyeur-mélangeur motorisé de provende conçu à base de matériaux locaux. L’étude dynamique et dimensionnelle faite a permis la réalisation d’un prototype de 350 litres en contenance. Pour évaluer le taux d’homogénéité de la machine, trois types d’aliments ont été utilisés, à savoir: (1) démarrage (2) poulet et (3) pondeuse. En plus des aliments, le coefficient de variabilité entre les échantillons après analyse chimique a été obtenu pour chaque temps de mélange choisi. La détermination des différents modèles rationnels optimaux du taux d’homogénéité a été faite avec Matlab R2017a pour déterminer le temps minimal de mélange. Les résultats de cette étude montrent que la machine développée permet le mélange, de manière homogène, de 427 kg d’aliment par heure avec une consommation d’énergie maximale de 0,72 Wh/kg. Le coefficient de variabilité de l’aliment est inférieur à 10 % en 12 minutes de mélange, d’où de meilleurs taux d’homogénéité. La consommation spécifique d’énergie est de l’ordre de 59 %. Cette machine présente une faible pollution environnementale (peu de bruit et de poussières), une ergonomie et une stabilité assurées; aussi, la maintenance est aisée. Le coût estimatif de développement du prototype est d’environ 381300 FCFA, soit 568 USD; cette machine est donc accessible aux éleveurs moyens. Les résultats de cette étude montrent également que, comparativement à ce qui existe sur le marché camerounais, cette machine présente plusieurs avantages pour améliorer les techniques d’élevage et les conditions de vie des populations.
Author Keywords: coefficient de variabilité, taux d’homogénéité, capacité horaire, consommation énergétique, alimentation animale.
