Professional kettles are versatile kitchen equipment which are under constant development aiming to improve current functions and implement new functions. Equipment with increased functionality enables better use of kitchen space, more flexible processes, better utilization rate of the equipment and smaller cost of total kitchen price. Combining of equipment into a single unit can also be seen positive for environment.

Aim of this master thesis was to design option for professional kettle which enables functionality of certain kitchen equipment to be added to the kettle. Addition is expected to raise interest of professional kitchens in the possibilities of the cooking process. Development process was carried out with VDI 2221 methodology. Design process begun from task clarification where list of requirements for the product was defined, continued by conception phase where different concepts were developed. Best concept was embodied. The results of the design process were verified by building a functional prototype of the concept.

Objectives of this thesis were achieved. The parameters for the cooking process in question were achieved with the prototype as well as level of usability and functionality. The technical and economic information along with assessment of usability needed for the decision-making process about productization of the option were provided with this thesis.
