As part of the project, an automated marking apparatus was designed and built by Scott Technology. It consisted of a two-axis manipulator with spray head and food-safe ink. This system was designed to be easily and temporarily integrated into the existing installation to allow quick installation and removal following the carcase marking trials.
A trial was conducted at an Australian processing plant where carcases were x-rayed by the Scott system, their cut positions calculated, and these cut positions were then sprayed onto the exterior surface of the carcases with the automated marking apparatus.
The project confirmed that DEXA derived cut positions can be successfully sprayed onto the visible external surface of lamb carcases by an automated applicator at the desired heights and angles. The MEFE Halal Food Grade ink worked well when sprayed and was unable to be rubbed off immediately after application on hot lamb carcases.
