Abstract
The separation of palm kernel from the shell is an important process in the
recovery of the kernel for use in vegetable oil production. The inherent
shortcoming of the fertiliser spinner spreader, resulting in non-uniform
distribution, has led to investigations into the possibility of its use in the
separation of palm kernel from shell. The differences in the physical
properties of the kernel and shell provided the basis for separation. Models
describing the motion of the kernel and the shell on a spinning disc with
vanes, feeding a segment at a time, were developed, and comparisons between
the predictions and experimental results were made.
Discharge angles obtained from the predictive models and from the
experiment were in close agreement. The experiment, however, indicated a
mid-span, between the discharge angles for kernels and shells, containing the
mixture. The models reasonably predict approximate ranges of discharge
angles for palm kernels and shells on a spinning disc with specified diameter,
friction coefficient and rotational speed.
