How does a Hannaford mobile seed processor achieve these objectives?
All Hannaford seed processors working across Australia have the same separation and treating capabilities, and incorporate the following five steps: • Grain is threshed to remove whitecoats in wheat and awns in barley. The thresher can be adjusted to a soft thresh or bypassed by the operator when processing legumes. • Air separation occurs at two places on the Hannaford processor. The principal is to run a curtain of grain over a flow of air blowing the lighter material into a settling chamber and sending the clean grain onto the next process. • Foreign seeds and longer material such as straws are next removed through indented cylinders. The ‘indents’ work on centrifugal force by picking up the grain in the cylinder pockets and depositing into an internal auger and rejecting all longer material. The indented cylinders are critical to the cleaning aspect of seed processing and dictate at what capacity a given sample may be processed effectively. • Screening is the final separation tool
