Robertson has one of the best casing plants in South Africa. Despite the process of cleaning casings being an initially dirty process with a low risk end product the factory standards are comparable to a mainstream food factory.
The end product that comes from the factory can be considered and bench marked along with the best in the world There are two main reasons for this.
Firstly; all of the casings are either produced from the groups own abattoir or if demand requires sourced from local abattoirs within a few hours drive of the factory. This means that all of the casings are cleaned within 72 hours of being slaughtered. There are a number of benefits to this that are evident in the end product. The casings produced are exceptionally white and strong when compared with casings that have only been salted and refrigerated before final processing. The length of time between slaughter and final processing has a critical impact on the quality of the end product.
Secondly; the premium casings are only produced (cleaned, calibrated and graded) by hand rather than machines. Producing the casings by hand allows for consistent cleaning and less damage to the casings. Producing by hand allows the factory to manage the natural variation in the sheep casings that a machine simply cannot.
The casings are graded and calibrated according to the different customers requirements based on the end product needs. It is essential for the final producers productivity that the calibration is accurate to ensure their products are of the highest quality whilst maintaining yields and production efficiency.
The grading of the casings in terms of worm beds and whiskers is also done by hand as is standard practice and is entirely according to the individual customers requirements.
