Abstract

Manual dehulling of pumpkin seeds is very tedious. To explore the possibility of developing a mechanical dehulling process, the engineering properties of seed kernels and hulls, e.g. dehulling load, surface roughness, transport velocity and densities, were studied. Effects of size and moisture conditioning on some properties were also evaluated. Results showed that it is possible to dehull the seeds mechanically, by a system in which the sharp tips of the seeds impinge on a hard surface. It is also possible to separate kernels, hulls and any unhulled seeds in suitable equipment, on the basis of differences in properties such as surface roughness, densities and transport velocities.
