Which combi oven should I buy?
RATIONAL combi ovens offer numerous advantages. These include the technology, quality, service, training and troubleshooting. Find out more about the RATIONAL advantages below:
Technology and features.
Precise climate
In combi ovens, a precise cooking cabinet climate is crucial
because it ensures consistently high and reproducible food quality.
The intelligent climate management function in the iCombi Pro, iDensityControl,
ensures that cooking cabinet conditions are adapted to the requirements
of the food being cooked by using sensors, active dehumidification and
a flow-optimised cooking cabinet geometry.
Planning pre-installed cooking programs
Pre-installed cooking programs are available in the iCombi Pro, which are very easy to use, thanks to the iCookingSuite. Simply specify the desired cooking result, such as browning or cooking level, and the intelligent cooking control will automatically adjust all the relevant parameters, such as temperature, cooking cabinet climate and cooking time. The sensors detect the size, quantity and condition of the food, reacting dynamically to the cooking process. The automatic adjustment of the cooking parameters can
help to achieve the desired cooking results with less monitoring
required.
Mixed loads without flavour transfer
The iCombi Pro enables mixed loading through
the individual monitoring of the racks by iProductionManager. It automatically
detects how far along each product is in the cooking process and notifies you when it is ready
. Cooking times are automatically adjusted, such as to the time the door remains open
.
Automatic cleaning and descaling
The iCareSystem recognises the degree of soiling of the iCombi Pro and recommends the appropriate cleaning procedure, including the necessary amounts of cleaner and descaler. Dosing is automatic based on the detected degree of soiling. Descaling also takes place automatically if necessary. Additionally, cleaning time schedules can be created and saved individually, and tailored to operating times and hygiene requirements.
Easy to operate, including for new staff
With MyDisplay, predefined dishes can be
be selected directly on the display using images or icons. Once selected,
the iCombi Pro will automatically start the corresponding cooking process. This can
make operation easier and help to ensure
consistent quality.
Digital networking with ConnectedCooking
With ConnectedCooking, cooking programs can be distributed, unit software updated and HACCP data documented centrally, regardless of where the cooking system is located.
Efficient use of resources.
High energy efficiency can help to reduce operating costs, depending on usage and operating conditions
A study shows that modern kitchen technology can reduce energy consumption by more than 24 % and water consumption by over 45 % (according to a study on energy and water savings in the AXA Deutschland staff canteen) – whilst simultaneously improving food quality and working conditions.
