PERFORMANCE EVALUATION OF AN INTEGRATED GROUNDNUT OIL EXTRACTION MACHINE
Publication Date : 01/02/2016
An integrated groundnut oil extraction machine previously development at the Department of Agricultural Engineering, Bayero University Kano was evaluated. Throughput capacity (kg/hr), extraction rate (Lit/hr) and extraction efficiency (%) were used as performance indicators, while variety of groundnut seeds (Manipintar and Ex-Dakar), kneading speed on the paste (200, 111 and 73 rpm) and quantity of groundnut seeds (24, 16.8 and 12 kg) were used as experimental factors. The experiment was conducted using 2x3x3 factorial in completely randomized design (CRD) and the treatments were replicated three (3) times. Thus, a total of fifty four (54) experiments were conducted with the samples at 2.52 and 2.69% (db) moisture content for Manipintar and Ex-Dakar variety respectively. The oil content of the samples obtained were 50.40 and 49.20% for Manipintar and Ex-Dakar variety respectively. Results revealed that the highest throughput capacity achieved was 24.45 kg/hr with combination of V2 (Ex-Dakar Variety), KS (200 rpm) and Q1 (24 kg). The highest extraction rate achieved was 7.90 Lit/hr with combination of of V1 (Manipintar Variety), KS1 (200 rpm) and Q1 (24 kg). Also, the highest extraction efficiency of 78.59% was achieved with combination of V1 (Manipintar Variety), KS1 (200 rpm) and Q3 (12 kg). Comparing the results with what was obtained using the traditional method represents 552, 852 and 21% increase in throughput capacity, extraction rate and extraction efficiency respectively.
