Seed Coat Separation Apparatus for Leguminous Seeds

This project, which earned me a score of 19.5 out of 20 for my undergraduate thesis, focused on designing a Legume Seed Husking Machine. This machine efficiently separates the husk or shell from legume seeds, particularly small legumes like mung beans and lentils, to maximize protein extraction while minimizing waste.

Legumes are known for their high protein content, primarily found in the seed embryo, with no protein in the husk. Including the husk in legume-based products increases protein impurities. The machine achieves husking with minimal damage and waste, ensuring a high protein yield.

The machine’s operation involves feeding categorized legume seeds into it, powered by a three-phase electric supply. Roller mills with needle-like blades rotate at 3000 RPM, husking the seeds without damaging other components. The two-stage process ensures a 100% husking rate with over 90-95% efficiency.

The machine’s output, primarily raw protein, finds applications in various industries, including animal feed, dairy, human consumption, drilling, cosmetics, pharmaceuticals, and more. Its key components include the chassis, nano filter, roller mills, and two outlets for separated husks and husked legume seed material.

In summary, this Legume Seed Husking Machine maximizes protein extraction from legumes while minimizing waste, serving as a valuable asset in various industries.
