Groundbreaking NuTech evisceration
With the launch of the Stork NuTech evisceration and giblet harvesting system, 1993 saw a truly groundbreaking event in the history of automatic evisceration.
NuTech’s main evisceration departure was the complete separation of the viscera pack from the carcass and its automatic rehang to a separate giblet harvesting line. For veterinary inspection, carcass and giblet harvesting lines had to be synchronized in such a way that carcasses and the packs taken from them were always presented together to the veterinarian. Rejection of a pack would mean rejection of its carcass.
The transfer of each pack to its own shackle opened the way for harvesting all edible giblets automatically. Even where giblets were still being harvested manually, the new method brought considerable advantages.
Giving each viscera pack its own shackle upgraded the image of giblets as products in their own right and not just by-products. The flexibility of harvesting giblets from a shackle suspended from an overhead conveyor system meant that this operation could now be done in an adjoining room and at a height convenient for operatives. By color-coding pack shackles, individual operative performance could now be monitored, resulting in a substantial increase in giblet yields. There was a hygiene benefit too. Viscera packs were transferred to their shackles with intestines hanging down and away from the edible giblets.
Virtually right from its launch, fully automatic giblet harvesting was a NuTech option. Whereas manual giblet harvesting was often the first to suffer when processing plants were short of labor, this process was now no longer reliant on people. Not only did NuTech save a lot of labor, fully automatic giblet harvesting meant that giblet yields could leap too.
They say that imitation is the sincerest form of flattery. All equipment suppliers now offer systems based on the automatic transfer of giblet packs to a separate pack shackle pioneered by Stork.
