The present invention relates to household food-processing devices. In order to provide a household food-processing device with a mounting system ensuring that it is not possible to touch the processing tool in an operating state, a household food-processing device (10) is provided that comprises a base unit (12), a processing tool unit (14) with a processing tool (18) for processing supplied food, and a receiving unit (16) with a receiving volume (20) for receiving the processed food. The base unit provides a driving force for actuating the processing tool. The receiving unit is mountable to the processing tool unit, and the base unit is mountable to the processing tool unit. The processing tool unit is provided with a safety mounting mechanism (38) defining a mounting order, according to which the base unit is mountable to the processing tool unit only when the receiving unit is mounted to the processing tool unit; and according to which the de-mounting of the receiving unit from the processing tool unit is blocked when the base unit is mounted to the processing tool unit.
