Abstract:
The present invention relates to a drying station for at least one ceramic product (P) having at least one upper surface with at least one upper layer (S) adjacent to such upper surface, the dryer assembly comprising: at least one supporting structure (2) delimiting, between at least one loading opening or inlet (3) for the at least one pre-treated ceramic product (P), and at least one discharge opening or outlet (4), a drying chamber (5) for the at least one ceramic product; at least one dryer assembly (7) for such at least one ceramic product (p), the dryer assembly being intended, in use, fordrying the at least one ceramic product (P) in the drying chamber (5). The dryer assembly (7) comprises selective heating means (8) of said at least one layer (S).
Abstract:
A system is provided for controlling a line speed of a conveyor belt [22] of a conveyor system [12] during product changeovers in a wallboard production line [14]. A central control module [40] controls operation of a position sensor [36] and a database [42]. The position sensor [36] is located on top of a conveyor table [18] for providing positional information of a slurry head [34] formed in front of a forming plate [28] of the conveyor system [12]. A position detection module [48] receives a position signal [P] from the position sensor [36], and determines whether the slurry head [34] is located within a predetermined distance relative to the position sensor [36] based on the position signal [P]. A speed adjustment module [50] regulates the line speed of the conveyor belt [22] based on the position signal [P].

Abstract:
Eine Vorrichtung (1) zum Temperieren von Fahrzeugkarosserien, insbesondere zum Trocknen von beschichteten Fahrzeug karosserien (9), umfasst in bekannter Weise ein Gehäuse (2), einen im Gehäuse (2) untergebrachten Temperiertunnel (7, mindestens einen in einem Gehäuse (2) untergebrachten, durch eine Wand (3, 4) von dem Temperiertunnel (7) getrenn ten Druckraum (5, 6), eine Mehrzahl von Düsen (10, 11) in der Wand (3, 4) sowie eine Lufttemperiereinrichtung, welche temperierte Luft in den Druckraum (5, 6) derart einbringt, dass diese durch die Düsen (10, 11) in den Temperiertunnel (7) einströmen und die dortige Fahrzeugkarosserie (9) beaufschlagen kann. Mindestens eine Düseneinrichtung (14, 15) ist so orientiert und besitzt eine so große Wurfweite, dass der aus ihr austretende Luftstrom eine Öffnung der Fahrzeugkarosserie (9) auf der der Düseneinrichtung (14, 15) zugewandten Seite durchqueren und eine Innenfläche der Fahrzeugkarosserie (9) auf der gegenüberliegenden Seite beaufschlagen kann. Mit der erfindungsgemäßen Vorrichtung gelingt die Temperierung einer Fahrzeugkarosserie (9) erheblich schneller als beim Stande der Technik und mit geringerem Energieaufwand, da die zu temperierenden Komponenten der Fahrzeugkarosserie (9) von gegenüberliegenden Seiten mit temperierter Luft beaufschlagt werden.
Abstract:
A drier for drying wet material includes a drying chamber with a plurality of heating region regions and a plurality of drying regions, alternatively located along the path of the material through the drier. Each of the heating regions is heated with heating fluid by a heating recirculation system wherein the heating fluid overall flows in heat exchange with the material in the chamber, but wherein the heating fluid can flow in various ways within each heating region. A fluid circulation system flows drying fluid through each of the drying regions generally in countercurrent flow relative to the flow of material through the drier, although the drying fluid can flow in various ways within each drying region. The drying fluid exiting the drier is used to preheat the heating fluid exiting the drier prior to the heating fluid reentering the drier. Makeup heat is supplied to the system.
Abstract:
A microwave applicator assembly (100) includes a microwave applicator (102) that excites TE modes and provides a generally circular heating pattern in a lossy dielectric material. The microwave applicator has a processing chamber bounded by a circumferential wall (110) in which a plurality of indents (102) are formed. The microwave applicator assembly (100) may further include a feed waveguide (120) coupled to the microwave applicator (102) for inputting microwaves into the processing chamber. The microwave applicator assembly (100) may further include one or more choking sections in communication with the processing chamber (104) to enhance heating efficiency and reduce microwave leakage.
Abstract:
An apparatus for drying tiles comprises moving means (6) suitable for supporting and moving said tiles (2) on a conveying plane (P) through a drying zone (4) provided with drying means (17); said drying means (17) is movable with respect to said conveying plane (P) so that when one of said tiles (2) to be dried is introduced into said drying zone (4), there is induced a suitable movement of said drying means (17).
Abstract:
Disclosed is an apparatus and method for the uniform drying of boards, such as gypsum wallboards. The apparatus includes a dryer through which a series of boards are conveyed in a side-by-side relationship. While in the dryer, heated air is delivered over the boards via a series of separate air channels. A bypass duct delivers a portion of or a totality of unreheated air to the outermost channels where the cooler air displaces a volume of the warmer air. As a result, the air in the outermost channels is cooler than the air in the interior channels. Air from the outermost channels is then directed over the exposed longitudinal edges of the boards.
