The present disclosure relates to a roasting apparatus and a method of controlling the roasting apparatus, and more particularly, to a roasting apparatus for roasting objects while stirring the objects in a roasting chamber, and a method of controlling the roasting apparatus. An roasting apparatus for heating objects according to the present disclosure includes a roasting chamber part which includes: a cylindrical roasting chamber that extends in a vertical direction and has an internal space in which the objects are stirred; and a rotary stirring part that rotates to stir the objects received in the roasting chamber and rotates about a stirring axis defined in the vertical direction. The roasting apparatus further includes heat source parts which supply heat to the roasting chamber part.

An ultrafine bubble generating apparatus and an ultrafine bubble generating method capable of efficiently generating an ultrafine bubble-containing liquid with high purity are provided. In order to this, a heating element provided in a liquid is caused to generate heat, and film boiling is made on an interface between the liquid and the heating element. A film boiling bubble is generated by the film boiling, and ultrafine bubbles are thus generated near the film boiling bubble.

In order to heat a bag filled, for example, with a food product to a predeterminable temperature, the entire cassette (1) has been heated in the past. The invention relates to a cassette (1) made of plastic, wherein in each of the cassette shells (2, 3) a receiving recess (10) is formed, in each of which a respective heat-conducting plate (11) is arranged securely in position. A heating element (20) is applied to the heat-conducting plate (11) and the heat-conducting plate (11) is retained in an insulated manner on the respective cassette shell (2, 3) such that a thermal insulating air gap remains between the heat-conducting plate (11) or the heating element (20) and the cassette shell (2, 3).

A domestic liquid heating apparatus includes a liquid heating chamber and an electrical heating arrangement arranged to heat, in use, a liquid contained in the liquid heating chamber. The apparatus further includes a handle, for lifting the apparatus, and a user interface, arranged on the handle. The user interface comprises a rotatable dial, operable to select at least one operational parameter of the apparatus, and a display, arranged to display the selected operational parameter.

A sous vide device (100) including an outer housing (104) within which there is located a heated tube (448) surrounding inner tubular wall (311), with the inner tubular wall (311) providing a first duct (461), and a second duct (462) being provided between the inner tubular wall and outer tubular wall with the first duct (461) and second duct (462) co-operating to provide a fluid flow path extending from an inlet (107) to an outlet (106), with vanes (450) being attached to the inner tubular wall (311) so as to be rotatably driven thereby to cause the liquid to pass along the fluid flow path.

The roasting apparatus further includes heat source parts which supply heat to the roasting chamber part.

A protective case of a intelligent cup warmer includes a shell, a control circuit board, a heating device a thermal conductive tray, and a touch sensing switch. The thermal conductive tray is disposed on an upper side of the shell. The shell includes an installation chamber for accommodating the heating device and the control circuit board. An upper surface of the thermal conductive tray is configured to heat cups, a bottom surface of the thermal conductive tray are connected the heating device. The touch sensing switch includes a touch sensing area disposed on the shell, integrated with the shell and formed with the shell in the same molding process. The induction element is disposed between the touch sensing area and the control circuit board, one end of the induction element is in connected to the touch sensing area, and the other end is electrically connected to the control circuit board.

A cooking device comprising: one or more heating elements for heating a fluid; and a control system configured to: control the one or more heating elements for a first period of time in order to heat the fluid to a first temperature; control the one or more heating elements for a second period of time such that the temperature of the fluid falls to a second temperature; and control the one or more heating elements for a third period of time to increase power supplied to the one or more heating elements relative to power supplied to the one or more heating elements during the second period of time.

An electric kettle may include a body formed by an outer body and an inner body having a cylindrical shape and an open upper surface and an open lower surface, a heat insulation space being formed between the outer body and the inner body, a lid configured to open or close the open upper surface of the body, a heating module configured to partition an inside of the inner body vertically and heat fluid, such as water inside of the inner body, a mounting portion which is formed on an inner surface of the inner body and on which the heating module is mounted, and a base on which a lower surface of the body is seated and which transfers power applied from outside to the heating module when the body is seated. The heating module may include a heating plate inserted through the open lower surface of the inner body and coupled to the mounting portion to form a bottom surface of the inner body, and a heater provided on a lower surface of the heating plate to generate heat.
