Grass Seed Cleaner

Development

Concept generation and idea exploration were performed to design a new industrial grass seed cleaning device for a medium size throughput.

The goal was to be able to clean grass seed from chaff and other contamination in the first stage. During the second stage, grass seed was purified to a 95+% purity of fertile seed.

Proof of Concept

Using sheet metal, CNC machining and other fabrication techniques, functional prototypes were produced for a proof of concept.

First stage seed cleaning was based on traditional cleaning, using vibrating sieves and gravity.

Second stage cleaning (purification) was based on the mass difference of fertile and non fertile seed, using vacuum extraction and gravity.
