Seed Processing

From the time the seed arrives by truck, it is carefully tracked. Having been weighed and the moisture tested, any drying is carried out before it is delivered into the cleaning system, or temporarily stored in one of 120 silos.

The Westrup screen/air machine is first in the processing system. It is a system of vibrating screens through which the seed travels, and stubble, weed seeds, plant debris, dirt and stones, insects, husks and any other contaminants are removed. Indent cylinders separate short from long seeds, and the gravity table separates light from heavy.

Should a line of seed pose a problem, Tatiara Seeds can meet that challenge with specialised equipment including five sets of velvet rollers and three double spirals. Velvet rollers separate seed by surface type and do an excellent job of removing dock, wireweed and yellow burr weed from lucerne, persian and white clovers. The spirals separate flat from round seed.

When the seed is clean, it is either kept in bulk or bagged for storage in the 8,000 square metre warehouse. From there it is loaded into containers for export, or despatched to Australian destinations.

The on-site seed laboratory can check for germination and purity of the seed.
Tatiara Seeds organises all the paperwork for the seed, including inspection of containers, arranging AQIS testing of seed, sending samples for official purity and germination testing, and tracking of the product at every stage.
