What do robots do in the food industry? The possible applications are immense. They refine cheese by turning huge cheese wheels and brushing them regularly. They cut up slippery squid. They can even sort vegetables and fruit according to quality characteristics better than humans, ‘evaluating’ aroma, colour, and texture with the aid of sensors and AI. In Japan, they have long been placing pieces of fish on rice balls and rolling maki sushi with impressive precision. Robotic arms knead pasta dough, conjure up latte art on cappuccinos or decorations on desserts and cakes.
Robots have been at the forefront of order picking and palletising for quite some time. They work hard and never tire. Collaborative robots (Cobots) that work alongside humans without protective fencing and without endangering them are on the rise. Another trend is mobile robot cells that are used on different production lines. Thanks to AI and 3D vision systems, palletisers are taking on increasingly complex tasks, such as putting together mixed pallets. And they learn faster than before; programming seems to be intuitive. AI analysis also makes it possible to predict maintenance requirements before a breakdown occurs (predictive maintenance).
Hygienic design specifically for food production
There are specific requirements in the food and feed industry. These industries lag behind the automotive and electronics industries when it comes to the use of robots. But they are catching up. Companies that already have their first robots in use are planning to purchase more (according to DLG Trend Monitor 2023). Models with a hygienic design are used in these industries, often made of stainless steel with particularly smooth surfaces. They are easy to clean and can withstand a lot, such as the jet of a high-pressure cleaner (with IP69K protection) and aggressive cleaning agents and disinfectants. Numerous details such as sealed cable routing and special grippers are part of the hygiene concept. Pressurising the robot arm prevents microorganisms from entering it. The lubricants used must also be harmless to health.
