| Performance evaluations of three coconut cracking devices was carried out and its results compared with the conventional (hand cracking technique) of hitting on hard surface. The three devices include a punch-split device, an impact-split device and hydraulic press split device which were developed at the Department of Agricultural & Bioenvironmental Engineering Technology, Federal College of Agriculture, Ishiagu. Each technique was evaluated for output capacity, cracking efficiency, ergonomics, and time required to crack a unit of different grades of coconut. The average cracking efficiency for punch split was 87.09 per cent with a range of 86.76 to 95.00 per cent, impact split efficiency varied from 83.33 to 95.00 per cent with the average of... |
