The present disclosure relates to a stirring blade for attachment to a support plate, and to a combination of a stirring blade and of a support plate, for use in a mixing vat of a mixing apparatus. The support plate is attached to a driving element of the mixing apparatus. The stirring blade has an elongate section for mixing a content of the vat. The stirring blade also defines an aperture for attachment of the stirring blade to the support plate. The aperture is configured so that raising the stirring blade away from the bottom surface of the vat causes an upper surface of the stirring blade to abut on a stop of the support plate, and raising the driving element and the support plate away from the bottom of the vat allows the stirring blade to pivot downward about the support plate for easy removal of the stirring blade.
