Alfred Hannaford (1890 – 25 August 1969) was a South Australian inventor and industrialist, remembered for his wheat pickling machines.
[1] The machine was capable of treating eight to twelve bags of wheat with bluestone (copper sulphate) solution and separating smut and other contamination from whole grain prior to planting.
The apparatus was based on a trough with a copper Archimedean screw to transport the grain from the input hopper to the delivery spout.
He then purchased rights to the Farm Type Carter wheat separator, which performed the grading function with a greater degree of discrimination.
He married (Ivy) Julia Hill ( – 1975) on 2 April 1913, lived at "Wattle Vale", Riverton, later Norman Street, Woodville.. Their children include: Kay Hannaford.
