Any industry that handles raw meat offers an interesting set of challenges, with cross contamination and bacterial transfer being major issues that have to be countered. For this reason, regular cleaning at high pressure, high temperature and with chemicals is the norm.
The mechanical design of exterior components and machine chassis and casings is a mature and proven discipline, but any additions outside of this mechanical “comfort zone” can introduce trap points and voids. This is not a particularly straightforward exercise.
According to Josep Tarradas, Automation Manager at Metalquimia: “We had a wide choice of existing displays, but they all had issues relating to how we were going to deploy them. We needed to develop one with a larger and more effective bezel in order to prevent environmental ingress. We also needed something that offered us a nice look, as we did not want to upset the clean, modern lines of our machines.”
Any new HMI design has to resist a two-pronged attack: prevention of contamination and resistance to harsh cleaning regimens. These capabilities have to be addressed in a solution that would also be sympathetic to the design of the rest of the machine. Ideally it needed to be certified too, to give end users to confidence that any new developments or design tweaks do not have a detrimental effect on the machine’s hygiene rating.
