P 41 15 471.1 05647 Electrically Powered Food Processing Apparatus The invention is directed to an electrically powered food processing apparatus for processing and preparing any type of food, receiving in a housing (1) an electric motor (8) rotating a processing tool located in a working vessel for processing the food material. The electric motor (8) is supplied with cooling air by means of a motor-driven impeller (38) rotatably arranged in the housing (1), and the electric motor (8) and the impeller (33) are disposed in an air duct (4) providing at its one end an air inlet (45) and at its other end an air outlet (46). To obtain a food processor of a construction as compact as possible, yet with a high motor output rating, while at the same time motor noise is reduced, the impeller (38) is driven by an additional electrically powered impeller motor (30) arranged in the housing (1) separate from the electric motor (8), and the impeller motor (30) is not connected to the supply until a predeterminable power input of the electric motor (8) is exceeded. ----27 Mar 92/BH.
