Abstract

A rotary separator was developed to separate the kernels and shells of pili nut after longitudinal compression. The machine was primarily composed of a separator drum with a design based on the size distribution of pili and kernels obtained using a sieve shaker. Using pili nuts with moisture content of 11.05±0.38% wet basis, the machine was tested using drum speeds of 32rpm, 42rpm and 52rpm and at 118mm and 178mm drum helix pitches. It performed well at 32rpm drum speed and at 118mm helix pitch, resulting to a throughput capacity of 96.45kg/h, separation capacity of 6.43 kg/h and separation efficiency of 50%. A slower speed of rotation and a shorter helix pitch was recommended to further improve the output purity (14.6%) of the machine.
