Abstract: A device is provided for extracting paste from a kneading machine, in particular a kneading machine having a cylindrical vessel with a vertical axis of rotation, provided with a spiral type kneading tool which has a vertical axis and is mounted eccentrically relative to the axis of rotation of the vessel and which is driven by a driving device partly disposed in a housing in alignment with the tool. This device comprises a withdrawable paste extractor having an intermediate position of equilibrium between a working position and a withdrawn position, and a pivotable main cover having a shape complementary to the shape of the extractor so as to prevent access to the vessel when the extractor is in the intermediate position of equilibrium or the working position.

Abstract: The machine comprises a container supported by settable legs so as to make the machine perfectly vertical on its support. The container contains a filter opening into a discharge duct and supporting at its upper portion a cylinder containing at its base a motor and reduction gear assembly driving a central vertical shaft, said assembly being covered by a fixed bottom formed with a radial opening connected to a nozzle emerging above the aforementioned filter. The machine has a disc having at least one boss in relief driven by the shaft and coated on its upper portion with an abrasive layer. The cylinder is closed by a water tight cover through which the products to be cleaned have been introduced while said products are discharged after having been cleaned through a door placed in front of a discharge chute.
