Agro-oils are oils extracted from agro –seeds with oil potentials. These oils from Groundnuts, Melons, Maringa, Cocoa beans , Palm fruits and the likes are consumed by people due to their, medicinal and minerals content for human health. Their extractions requires quality approach and are costly therefore waste of these materials cannot be compromised. Hence the needs for machines that are of high effectiveness which is the products of efficiency, quality rate and availability. Cocoa beans processing machine was used as case study .By determining its efficiency, quality rate and availability and compared the results with the acceptable standards of these strategic decisions. The machine effectiveness acceptable standard was set at 0.85 (85%), but this case study shows 0.77 (77%). This is low compared with the acceptable standard of ≥ 0.85 with negative deviation of 0.08. This is caused by the low values of machine availability and Quality rate which should not be ≤ 0.90 and ≤ 0.99 respectively. The availability of the machine was improved to 0.94 and its quality rate to 0.97. This gave a new acceptable machine effectiveness of 0.875328 (87.5%) which led to better achievement on the cocoa oil yiled thus: Cocoa Liquor (chocolate colored paste from milled nibs), based on pure Cocoa Beans available (after foreign material removal) which is 14.2589% . The percentage of liquor available for pressing to get the oil called cocoa butter was 85.7411%. Cocoa Butter yield (based on total Cocoa Liquor was 35.25% while the Cake yield ( residue after oil extraction) was 43.95% Cocoa Butter waste (based on total Cocoa Liquor ) 2.435% and Coca cake wasted was 4.076%. This model will find its application in small, medium and large scale agro oil extraction industries.
