It’s all about speed….
• Speed from the tree to being packed
• While growers are “sorting for quality” they
are potentially degrading shelf-life through:
• Holding NIS in inadequate storage
facilities
• Sorting while they could harvest
• Spending money that may not need to be
eg gas, electricity, wages
How to do it fast!
• We developed a system that allows
growers to deliver with some husk, trash,
FM and gross rejects (within limits) to
achieve speed
Technology is the key

What should you do with this?
a.Throw it out
b.Leave it in
Conclusion
• Focus on consumer quality
• Technology has allowed us to do more
• Growers are seeing a 10-15c/kg saving in on farm costs by using the full system
• Plus increased production per hectare
• How much kernel have we as an industry lost over the years???????????
• How much shelf-life have we lost over the years???????
Quality is made in the
paddock
We can only preserve it after that,
not improve it
