Cooking appliance

A connected combi oven cooks many meals evenly and precisely and receives its cooking programmes centrally from the cloud. In 2004, RATIONAL introduced combi steamers that cook autonomously: you enter the desired result and the appliance cooks automatically. MKN loads cooking programmes onto its combi steamers via the Cloud of Things, so that rolls and croissants at the snack counter of a large retail chain always turn out the same.

An IoT platform loads cooking programmes and cookbooks centrally onto all connected combi steamers. MKN uses Deutsche Telekom's Cloud of Things for this, RATIONAL its own ConnectedCooking platform. Before ConnectedCooking, this was only possible by USB stick; today, a customer with many appliances transfers new software or recipes at the push of a button. The cloud also makes it possible to manage several kitchens at different locations.

The appliance documents the relevant data itself instead of staff keeping lists. At RATIONAL, every cooking process automatically goes into standardised, HACCP-compliant documentation. Among other things, MKN stores when the combi steamer was last cleaned and whether it kept the required temperature constant. Hobart gives catering businesses automatic proof of compliance with hygiene regulations through a hygiene check and log.

Connected appliances report faults automatically and supply the cause along with them. According to the solution example, around 25 percent of RATIONAL's service calls are handled remotely, and in about 40 percent of call-outs the cause of the fault is known in advance. Hobart combines automatic error messages with direct contact to a service partner, and the app shows the operator the troubleshooting steps in pictures.
