The present invention relates to a support structure configured for drying clay forms while being supported thereon. The support structure comprises a rectangular support surface provided with perforations, having two short and two long perimeter edges, and four support walls extending perpendicularly from the perimeter edges in the same direction. Each support wall is provided at its edge facing away from the support surface with a support wall flange extending parallel to and beneath the support surface. Optionally, the support structure includes a U-shaped reinforcement profile extending parallel to the long support walls between the support walls extending from the short perimeter edges. The ends of each leg of the U-shaped reinforcement profile are provided with securing elements extending perpendicularly to the legs, by which the reinforcement profile is attached to the support surface.

A dryer for ceramic products, such as for example slabs or tiles, comprising: a drying chamber (1): at least one drying channel (10), comprising a shelf (11) for one or more ceramic products: at least two manifolds (20), positioned respectively above and below the shelf (11), each of which is connected to a source of conditioned air. The manifold (20) located above the shelf (11) has an extended shape and is provided with a flat lower surface (21a), which in the plan view covers at least a portion of the shelf (11) and is provided with a plurality of lower openings (22a) for emitting the conditioned air into the drying channel (10). The manifold (20) located below the shelf (11) has an extended shape and is provided with a flat upper surface (21b), which in the plan view covers at least a portion of the shelf (11) and is provided with a plurality of upper openings (22b) for emitting the conditioned air into the drying channel (10).

A method for preparing a ceramic shell for precision casting. The method comprises: S1, smearing the exterior of a wax pattern with corresponding layers of ceramic shell slurry layer by layer, wherein a ceramic shell to be dried is obtained at a corresponding layer each time after the smearing of the ceramic shell slurry is completed; S2, putting said ceramic shell at each corresponding layer into a vacuum rapid drying system for a vacuum rapid drying treatment, and after the drying of the ceramic shell at the layer is completed, smearing same with a subsequent layer of ceramic shell slurry, wherein during the vacuum rapid drying treatment, image data of the ceramic shell to be dried is first acquired and subjected to model structure analysis so as to obtain the position, orientation and depth of a deep hole in the ceramic shell to be dried, same are sent to a fan set control module, the fan set control module performs fan set control analysis according to the position, orientation and depth of the deep hole in the ceramic shell to be dried and controls the starting and stopping and / or control parameters of each fan set according to an analysis result, and the drying time of all portions of the integral ceramic shell to be dried tends to be identical by means of vacuumizing a vacuum drying chamber and / or restoring the chamber pressure and controlling the starting and stopping and / or control parameters of all the fan sets; and S3, waiting for the completion of the drying of the ceramic shells at all the layers to obtain a ceramic shell for precision casting. On the basis of retaining the inherent advantages of a thick-slurry ceramic shell, the preparation method effectively overcomes problems present in the thick-slurry ceramic shell.

An air drying system (10) for ceramic products comprises a drying chamber (11), in which green ceramic substrates (SC) are dried, transit means (14) for the controlled passing through of the ceramic substrates (SC) in the chamber (11) and at least one first recirculation duct (16), connected to the chamber (11) and comprising a first fan (12) and a first burner (13) placed in flow communication by means of a first heat exchange device (15) which is operatively connected to a first heating circuit (CR1), supplied by a first source (S1) of a first heat carrier fluid to indirectly transfer heat from the first heat carrier fluid to the air circulating in the first duct (16). The system (10) further comprises a first monitoring and control unit (UMC) adapted to control the first fan (12), the first burner (13) and the transit means (14).
