Steam cooking method and steam cooking oven

摘要

Steam cooking method for operating a steam cooking oven (1) comprising at least the following steps:
- placing vacuum packed food stuff (2) in an oven cavity (5);
- a heating step comprising heating up the oven cavity (5) until the oven cavity centre has reached a defined temperature (T d ) by operating a steam generator (3) and supplying steam generated by the steam generator (3) into said oven cavity (5), wherein a convection fan (4) is operated within the oven cavity (5);
- a maintaining step comprising maintaining said oven cavity (5) at said defined temperature (T d ) of the oven cavity centre by operating said steam generator (3) and supplying steam generated by the steam generator (3) into said oven cavity (5) over a certain period of time while said defined temperature (T d ) of the oven cavity centre is not allowed to vary about more than +/-1,5°C;
- wherein at least during said heating step and said maintaining step the actual temperature (T a ) of the oven cavity centre is determined by a control unit of the steam cooking oven (2) by means of an algorithm that is based on the temperature values measured by a temperature sensor within the oven cavity (5) and wherein said actual temperature (T a ) is used to operate the steam generator such, that said defined temperature ((T d ) of the oven cavity centre is reached or maintained.
