  • Publication number: 20130236615
    Abstract: A method for providing cooking programs for at least one selectable product to be cooked, which can be cooked in at least two different charges in a cooking chamber of a cooking appliance. Cooking processes conducted depending on charge-dependent parameters are replaced by cooking programs that depend solely on fixed parameters. One cooking program is assigned to each charge respectively. A cooking process is conducted as a function of at least one charge-dependent parameter at least once for each charge, with a caliber-dependent parameter determined by a core temperature of the product to be cooked being selected as the charge-dependent parameter. A cooking process that leads to a specific cooking result is selected for each charge, with the cooking result being determined by the core temperature of the product and a cooking program being stored for each selected cooking process after the charge-dependent parameter is replaced by a fixed parameter.

  • Patent number: 8025740
    Abstract: A process for conducting cleaning operations at predetermined time intervals in a chamber or container of a fluid-receiving device of a foodstuff-processing apparatus first comprises receiving a first fluid in the chamber or container. Then, first and second degrees of cleaning are determined at first and second moments in time, respectively. Then, a first difference between the first and second degrees of cleaning is determined. In a first case, in which the second degree of cleaning lies below a first limit value, the action duration of the at least one cleaning agent during at least one subsequent cleaning operation is set depending on the first degree of cleaning. In a second case, in which the second degree of cleaning lies above the first limit value, a greater amount of cleaning agent is supplied and/or the time interval between two subsequent, successive cleaning operations is shortened.
