A steam generator for a cooking appliance is provided. The steam generator includes a warm tank having a water inlet. The steam generator also includes a heating element configured to heat water in the warm tank to produce steam to be directed into an oven cavity of the cooking appliance. The steam generator further includes a first cold tank having an input connected to a supply of water and an output, and a second cold tank having an input connected to the output of the first cold tank and an output configured to provide water to the water inlet of the warm tank.

Provided is an apparatus (100) for preparing a food puree comprising a chamber (102) for containing food ingredients and a steam supply (104) for supplying steam to the chamber for steaming the food ingredients. A liquid supply (106) supplies a liquid to the chamber and an agitator (108) purees the steamed food ingredients in the presence of the liquid to obtain the food puree. A user interface (110) permits user selection of a texture of the food puree. A controller determines a steam parameter and a liquid amount to be supplied by the liquid supply according to the user selection. The controller further controls the steam supply and the liquid supply according to the determined steam parameter and liquid amount. Further provided is a method for preparing the food puree.

A cooking appliance, in particular a commercial cooking appliance, comprising a cooking chamber; a motor-driven fan wheel which is arranged in an area which is separated from the cooking chamber by a suction plate having a central suction opening; a heating device which has one, at least two heating coils and is arranged around the fan wheel; an appliance control, the appliance control activating the heating coils independently of one another.

A toaster with a steam system comprises a casing and a chassis. A slot for a bread slice is defined by the chassis. A pop-up mechanism is within the casing and supported by the chassis, the pop-up mechanism configured for supporting a bread slice received via the at least one slot, and for raising the bread slice to project partially out of the slot at an end of a toasting/steaming process. Heating element(s) in the casing are for generating toasting heat. A steam system within the casing is configured for producing steam and feeding the steam to a steam vessel in the chassis during the toasting/steaming process. A closing system has flap(s) to close the at least one slot during the toasting/steaming process, and to open the at least one slot at completion of the toasting/steaming process.

A cooking method is used to prepare a food in the cooking chamber of a cooking device. The cooking chamber includes a first opening, a second opening and a closure for closing the second opening. Furthermore, the cooking device includes a temperature sensor arranged outside the cooking chamber for detecting gas volumes escaping from the cooking chamber through the first opening. During the cooking process, the closure is moved from a first position to a second position. After leaving the first position, a measurement is performed by means of the temperature sensor.

In a method for operating a household steam treatment appliance which includes an evaporator with a heatable water holding chamber and a fill level sensor with at least two measurement electrodes, which are disposed over one another at a distance from each other in the heatable water holding chamber, a water detection measured value provided for indicating wetting of the at least two measurement electrodes with water introduced into the water holding chamber is adapted in an adaptation process to an electrical conductivity of the water in the water holding chamber.

A method for calibrating an oxygen sensor of a household appliance includes a calibration process which is automatically started when at least one status parameter of the household appliance has at least reached a predetermined threshold value. The household appliance can be a steam cooking appliance, and the oxygen sensor can be a lambda probe.

A steam generator is provided. The steam generator may include a steam chamber, a steam heater to supply heat into the steam chamber, a water supply, through which water to generate steam may be supplied into the steam chamber, one or more interference members disposed in the steam chamber to interfere with a flow of the water introduced through the water supply, and at least one discharge to discharge the steam generated in the steam chamber. The one or more interference members may be disposed under the at least one discharge and above the water supply.

An apparatus comprises at least two cooking devices, a control unit, an input device and an output device. The control unit is adapted to determine if at least two of the foodstuffs to be cooked can be cooked in one of the cooking devices in an at least partly concurrent manner. Depending thereon, the control unit allocates the foodstuffs to be cooked to the cooking devices and outputs, via the output device, which of the foodstuffs can be cooked in which cooking device or in which cooking devices.

Examples of a pre-cooked instant food products and a process for preparing such food products are described. The process comprises the steps of i) steaming the food product for pre-determined time; ii) immersing the steamed food product in a high concentration cooled brine solution; iii) removing excess water from the surface of the food product; iv) packing a pre-determined amount of the food product into a container and sealing such container, and v) storing the containers of pre-cooked instant food products at temperatures of 2° C. or lower. The container is made of a material safe for keeping food products and is able to withstand temperatures higher than 90° C. The surface of the food product is coated with the salt from the brine solution to preserve it.
