The presently disclosed subject matter is directed to a method of extracting bioactive agents from biomass using continuous microwave-assisted extraction. The disclosed method includes contacting the biomass with a solvent and optionally homogenizing the biomass. Then blending the biomass and the solvent and continuously passing the biomass though one more microwave assisted extraction units, thereby exposing the biomass to microwave energy. The solvent is separated from the biomass, where the separated solvent is the bioactive agent.

A liner (10) for lining a microwave oven (M) to prevent food from adhering to the top (T), sides (R, L), and floor (F) of the microwave during the cooking of food. The liner has a top panel (12), and three side panels (18, 20, 22) which are initially folded in place with the top panel of the liner first being installed and then the other panels in a prescribed sequence. A two-sided tape (14) is used for adhering the panels to corresponding sides of the microwave. The liner further includes a panel (28) similarly installed on the floor of the microwave, this piece having a central opening which exposes the turntable installed in the floor of the microwave. A separate circularly shaped panel (30) attaches to the top of the turntable.

The invention relates to a household appliance, which comprises at least one catalytically effective substance in a surface, wherein the catalytically effective substance is a polyoxometalate that is comprised in an inner an/or outer surface of the household appliance, provided that the polyoxometalate is comprised at least in an outer surface of the household appliance if the household appliance is a water-bearing household appliance having a container for receiving objects to be cleaned. The invention further relates to a method for operating the household appliance.

A microwave oven is provided herein having a cooking cavity, a dividing shelf for dividing the cooking cavity into at least two sub-cavities, and a door movable between an open and closed position for selectively providing and preventing access to the sub-cavities respectively. The door is provided with a choke frame configured to communicate with the dividing shelf in the closed position so as to attenuate microwave transmission between the sub-cavities.

A device for producing exfoliated graphite from graphite flakes, intercalated graphite, or expanded graphite by means of microwave heating using single mode microwave cavities, a method of producing such materials and products from such methods.

An electromagnetic cooking device and method of controlling the same is provided herein. The cooking device has a cavity in which a liquid is placed and a plurality of RF feeds configured to introduce electromagnetic radiation into the cavity for heating the liquid. A controller is provided and is configured to: analyze forward and backward power at the plurality of RF feeds to calculate efficiency; determine and monitor a coefficient of variation of the efficiency; detect a specified temperature of the liquid based on changes in the coefficient of variation; and adjust a power level of the electromagnetic radiation in response to detection of the specified temperature.

An arc-shaped microwave oven is disclosed, including a cooking cavity, an oven base, a microwave generation unit disposed within the oven base, and a control unit also disposed within the oven base, wherein the oven base includes a bottom portion and a back portion that is assembled with the bottom portion, the cooking cavity is formed by a cavity surrounded by the bottom portion, the back portion and a furnace door, the furnace door is in a hood shape and provided with a microwave shielding cover, and the microwave generation unit and the control unit are electrically connected to an operation/display unit. The furnace door can be movably connected to the back portion, the furnace door can swing up and down relative to the bottom portion and the back portion to open and close respectively, and the furnace door can be in an arc hood shape.

An oven includes a plurality of walls, a fan, and a heating element. The plurality of walls defines an internal cavity in which food may be placed for cooking. A first of the plurality of walls defines a plurality of orifices that establishes fluid communication between the internal cavity and a fluid path. The fan is configured to direct air from the fluid path, through the plurality of orifices, and into the internal cavity. The heating element is disposed on the first of the plurality of walls and adjacent to the plurality of orifices. The heating element is configured to heat the air being directed from the fluid path, through the plurality of orifices, and into the internal cavity.

A microwave oven is provided herein having a cooking cavity, a dividing shelf for dividing the cooking cavity into at least two sub-cavities, and a door movable between an open and closed position for selectively providing and preventing access to the sub-cavities respectively. The door is provided with a choke frame configured to communicate with the dividing shelf in the closed position so as to attenuate microwave transmission between the sub-cavities.
