Abstract
An electric heating and stirring machine that heats and stirs a substance or substances placed in a carafe for brewing coffee, tea, or extracting substances into fats or oils. The device uses a motor to rotate a magnet holder upon which magnets are mounted. The rotation of the magnets magnetically rotates a stirrer, through attraction to the rotating magnets, rotation of the stirrer stirs the contents of the carafe. The contents of the carafe are heated, preferably by an infrared or induction heater located below the carafe. The base of the stirrer is heated via induction or direct infrared heat. The temperature of the substance in the carafe is measured by a thermometer. A control circuit can be used to control the speed of mixing, the temperature, and the time of both stirring and heating.
Claims17
An extraction brewer for extracting solids into liquids comprising:
- a carafe capable of containing liquid contents, the carafe having a top and a bottom, with sides extending between the top and bottom, and a perimeter around the sides;
- a heating element located proximate to the bottom of the carafe;
- a magnet located proximate to, and outside of, the sides of the carafe, the magnet located between the bottom and the top of the carafe, the magnet capable of movement in a path around the perimeter of the carafe;
- and
- a stirrer capable of fitting inside the carafe, the stirrer comprising
- a base;
- an elongated riser with a first end attached to the base and a second end extending away from the base;
- and
- a block attached to the second end of the elongated riser, the block capable of being attracted to the magnet,
- where when the stirrer is inserted inside the carafe, the base rests upon the bottom of the carafe, and the block is located between the bottom and top of the carafe, proximate to the location of the magnet.
An extraction mixer comprising:
- a carafe with an interior volume and an external surface, the interior volume capable of containing a liquid and a solid, the carafe having a bottom and sides;
- a heating element located proximate to the bottom of the carafe, the heating element capable of heating the liquid and the solid;
- a thermometer located proximate to the carafe, the thermometer capable of measuring the temperature of the liquid and the solid;
- a magnet capable of movement in a path around the external surface of the carafe, along the sides of the carafe;
- a motor capable of imparting rotational movement on the magnet;
- a stirrer capable of fitting inside the carafe, the stirrer comprised of:
- an area attracted to magnetic fields and which serves the purpose of being attracted to the magnet, creating a rotational movement of the stir rod, and
- an elongated riser attached to the area attracted to magnetic fields, the elongated riser elevating the area attracted to magnetic fields to a position above the heating surface;
- and
- a controller which takes input from both the thermometer and an operator to control the heating and stirring of the substances.
