Apples with Core Rot And Internal Browning Now Readily Identified

GP Graders Release Internal Apple Defect

MELBOURNE, Monday, 24 July 2017: Multi-award winning Melbourne-headquartered company, GP Graders have entered into a technology partnership with Ellips of Holland to revolutionise the ability for apple packers to identify apples with internal defects in order to meet the increasing supermarket demands which is crippling the industry.

“This cutting-edge technology will change the industry, and strengthen the packers ability to provide defect free apples to supermarkets,” said Stuart Payne, Managing Director, GP Graders.

The system uses light spectrometer technology and takes 10 images sliced across each apple to detect internal browning and core rot wherever it is located in the fruit.    

The technology doesn’t just shoot a beam of light through the centre of the apple to look at the core in isolation, it also analyses the entire mass of the apple, slicing the apple at 10 incremental stages in order to check for internal rot or browning wherever it is located through the fruit.  This is a standout feature of the technology as older technology only took one light image through the centre of an apple.

Ellips Chief Executive Officer, Erwin Baker oversaw the installation operating first hand at GP Graders’ head office in Melbourne, Australia, where the technology has been fitted to an operating apple line.  

Bins of apples were run through the system allowing GP Graders to intensively test and demonstrate the technology.

“The results were remarkable,” said Payne.

Of those apples discarded to an exit with a reading of internal browning and core rot, 100% of them in fact showed those characteristics when cut open.  Of those apples that were deemed not to have a reading of internal or core rot, only one single apple showed specific characteristics when cut into during the collation of test results.  The total sample size was 1,500 apples.  

On-site visits to GP Graders manufacturing plant to see the live demonstration of the technology working will be available until mid August with several sales already being concluded within days of its release.

GP Graders have been designing and manufacturing turn-key apple grading and packing lines since their beginning in 1963 with hundreds of packing lines in operations throughout Australia and the world.
