In summary, most of the machines are designed for the purpose of detaching and separating shell from seed. If the removal of the husks from the kernels is required, another seed cleaning system/device needs to be added. A concept has been proposed by Universiti Putra Malaysia to recover kernels directly from the whole fruits within a single machine as demonstrated in Fig. 11. It involves two stages, namely cracking and separation processes. Both stages consist of a double level cracking unit and a pneumatic separation unit complete with a blower and duct to supply air movement. Both stages have a similar design but with different roller clearances and blower speeds. Based on preliminary testing reports, the shell and husk removal achieved were 100.00% and 45.46% respectively. A total of 2.40% of the kernels were lost throughout the various stages in the process [75]. However, the technology is not mature and is still under development
