Abstract:
A power operated ash gourd seed extractor was developed, tested and its performance was
evaluated. The major parts were flexible shaft, cutting blades, V-groove, seed outlet and collecting
drum and an electric motor with a speed reduction unit of 6:1. The extraction took place due to the
scraping and scooping action of the cutting blades inside the fruit. The capacity and the seed extracting
efficiency were found to be 81.39 kg per hour and 97.5 % respectively at an optimum speed of 240
rpm. The ash gourd seeds showed the germination capacity of 85.5 % and 76.1 % by mechanical and
manual means respectively.
