Mechanical feed mixers are preferred for their higher efficiencies. A wide range of these feed mixers are available and used in the Ashanti and Brong Ahafo regions of Ghana due to a higher concentration of poultry farms in these regions. The performances of both local and foreign poultry feed mixers in the two regions were evaluated. This was carried out as a procedure to identify the types, measure machine parameters, operational parameters and feed characteristics relevant to the performance of poultry feed mixers. Data collected were analysed using statistical tools at 95% C.I. From the results, moisture content of the feed samples ranged from 9.21 to 11.08% (% wb), the geometric mean diameter of all samples ranged from 762.74 to 947.27 µm with the geometric standard deviation range of 2.35–2.50. The two dominating feed mixer types were the horizontal and vertical. The horizontal feed mixers indicated mixing time of 1.5–10 min, mixing speed of 40–80 rpm, energy consumption per mix of 0.9–3.8 kWh and blending uniformity with a coefficient of variation (CV = 7.19%), but relatively high maintenance cost per month. CV less than 10% is the percent commonly recognized by the feed industry as the cut-off for uniformity of mix analysis. The vertical feed mixers indicated low maintenance cost, mixing time of 15–30 min, mixing speed of 250–500 rpm, energy consumption per mix of 0.8–5.5 kWh and CV = 10.30–18.05%. Given that the horizontal feed mixers were found to have better performance metrics, there is the need to adapt the design for local process planning and manufacture, while substituting imported machine parts and components with locally available materials to optimize performance and minimise maintenance cost for the poultry and feed industries.

机械饲料混合器由于其较高的效率而被优选。由于加纳的家禽养殖场集中度较高，因此加纳的Ashanti和Brong Ahafo地区可使用并使用各种各样的饲料搅拌机。评价了这两个地区的本地和国外家禽饲料搅拌机的性能。这是作为识别类型，测量机器参数，操作参数和与家禽饲料混合机性能相关的饲料特性的程序进行的。使用统计工具在95％CI处对收集到的数据进行分析。从结果来看，饲料样品的水分含量范围为9.21至11.08％（％wb），所有样品的几何平均直径范围为762.74至947.27 µm，具有几何标准偏差范围为2.35–2.50。两种主要的饲料混合机类型是卧式和立式。卧式进料混合机的混合时间为1.5–10分钟，混合速度为40–80 rpm，每次混合的能耗为0.9–3.8 kWh，混合均匀性具有变异系数（CV = 7.19％），但是维护成本相对较高每月。CV低于10％是饲料行业通常认为是混合物分析均匀性的临界值。立式进料搅拌机的维护成本较低，搅拌时间为15–30分钟，搅拌速度为250–500 rpm，每次搅拌的能耗为0.8–5.5 kWh，CV = 10.30–18.05％。鉴于卧式进料混合器具有更好的性能指标，因此有必要针对本地工艺规划和制造对设计进行调整，
