Densities of melon seeds, kernels and hulls.

True density, bulk density and apparent density of the seeds, kernels and
hulls of commercial varieties of muskmelon, longmelon and watermelon
were determined. There is a significant difierence between the apparent
densities of kernels and of seeds. Kernels are denser than water whereas
seeds are less dense; hence kernels sink while seeds float in water. A
suitable water separation tank, either batch or continuous, based on this
property can be designed for separation of the kernel and seed fractions
obtained by mechanical dehulling of the melon seeds.
