Pelting

Most of the effort devoted to mechanized sheep slaughter and dressing has been in the area of pelt removal. Many research organizations, engineering companies, and other groups have developed and refined various concepts designed to reduce the manpower needed for pelting.

In the late 1970s, the New Zealand meat industry initiated and funded a project to mechanize the pelt removal operation. People began to recognize the hygiene and labor benefits of depelting sheep from the shoulders to the hind legs, a process more easily done by suspending the animal from the front legs; traditionally sheep were depelted while hanging from their hind legs. Systems using this new carcass orientation became known as inverted dressing systems. A six-head rotary pelt removal machine, developed for the inverted orientation, removed the pelt from the belly, lower back, and hind legs by driving a ring between the pelt and the carcass, removing the pelt as a "sock" (Fig. 2). The machine was completed and released in 1982.

MIRINZ took over the project in 1983 and developed a simpler two-stage pelting system as an alternative. This system consists of a shoulder puller (Fig. 3), which removes the pelt from the shoulder and back regions, and a final puller (Fig. 4), which pulls the pelt off the rear legs. MIRINZ has refined the manual input of the inverted dressing system by introducing new butchering techniques to enhance the advantages that the inverted dressing system has over the traditional system, that is, less labor required, lower levels of microbial contamination particularly in the most valuable hind quarter area, reduced skills level required, and lower worker injury risk.
