Abstract :

An Arecanut (Areca catechu L) prototype cracker was developed and tested. The cracker, comprises a rectangular convergent feeding zone, nozzle system, breaking plate, collector, powered by compressor arrangement. The equipment was conceived to split the shell and kernel of arecanuts through force by air pressure. Performance evaluation showed the moisture level and the rate of feeding of arecanuts and pneumatic pressure had significant effect at different levels on cracker's efficiency. Evaluation of chemical composition showed no significant (P>0.05) difference between cracked and uncracked samples. Based on the range of selected parameters the highest performance of the cracker was found to be the moisture level of 11.7% (db), feed rate, 25.3 kg/h and pneumatic pressure of 4 bars. The estimated capacity of the machine was 25.3 kg/h. The cracker does not require sizing of nuts prior to cracking, eliminating the laborious, time consuming current cracking methods.
