Abstract: The invention relates to a production station for use in producing at least one layered bed, in particular a plurality of layered beds, of a magneto caloric material, the station comprising a frame work and further for arrangement at the frame work the station comprising:—a material receptacle for receiving a particulate magnetocaloric material,—a dosing plate, having at least one intake opening adapted to receive a magneto-caloric material of one layer of the layered bed—at least one reservoir below the at least one intake opening, wherein the reservoir is adapted to receive the one or more layers of the particulate magnetocaloric material, wherein the production station further comprises:—a shutter plate arranged between the reservoir and the dosing plate, wherein the shutter plate is switchable through motion with respect to the dosing plate and wherein the shutterplate is arranged and adapted to at least activate a filling modus, wherein in the filling modus the at least one reservoir is filled with particulate magneto caloric material of the one layer of the layered bed by a switching control of the shutter plate.
