The invention discloses a steam-heated high-speed food processor, aiming at solving the technical problem of an existing food processor that food materials, when heated, can adhere to the bottom of the food processor. The food processor comprises a base, a water tank and a stirrer, wherein both the water tank and the stirrer are arranged on the base; a heating module, an air pump and a water tankcontrol module are arranged at the bottom of the water tank; a water passage pipeline is connected to the bottom of the water tank and the bottom of the stirrer; the heating module, under the controlof the water tank control module, is used for heating water in the water tank; and the air pump is used for pumping a water-vapor mixed body, which is heated until steam appears, into the water passage pipeline, so that the water-vapor mixed body enters the stirrer from the bottom of the stirrer. When the stirrer needs to be injected with water for heating food materials, steam and water, which are heated in the water tank, pass through the water passage pipeline and are injected from the bottom of the stirrer by virtue of the water pump, so that the food materials, when heated, are turned from bottom, and the food materials are prevented from adhering to the bottom of the food processor in a heating process; and a steaming box is arranged at the upper side of the water tank, and the foodmaterials in the steam box are heated by virtue of the steam in a stirring process, so that an effect of simultaneously implementing stirring and steaming is achieved.
