Article Title: Design, Fabrication and Evaluation of Palm Nut-Pulp Separator
by Nwankwojike B. Nduka, Odukwe A. Okay, Agunwamba C. Jonah

A palm nut-pulp separator consisting of a cake breaker, auger separator, hopper, 3HP electric motor, nut and pulp discharging chutes was designed, fabricated and evaluated. The results of its performance test indicated 90.05% and 419.92kg/h as the efficiency and throughput of the separator respectively. The results of the comparative analysis of introducing this machine in semi-mechanized small scale palm fruit processing showed significant differences in the amount of palm oil extracted and palm oil loss to pressed fibre in the existing semi-mechanized methods and this new technique. Also the results indicated no significant difference (at & = 0.05) in the oil loss to palm nuts between the two processes irrespective of the type of fruit processed. The average quantity of palm oil extracted is greater while oil loss to fibre is low with the mechanized process with palm nut-pulp separation was used and also this new technique eliminated nut breakage and second pressing operation. All materials used for fabrication were sourced locally, and the estimated cost of producing this machine is one hundred and twenty seven thousand, one hundred and sixty naira (N127,160.00).
Keywords: pressing, screw press, nut breakage, palm oil loss, nut-pulp separation, separator
