Abstract: A convertible drum-type coating apparatus for applying breading material to food products includes an in-line breader section, a rotary drum section, and an outflow section. The rotary drum is mounted on an elevator for lowering and lifting between a low use position and a high non-use position.

Abstract: A prototyping method and apparatus incorporating the invention enables rapid fabrication of heterogeneous parts with non-planar and/or layer-by-layer printing. An electronically addressable array of micro-electrodes is employed as a "printing" panel, A processor controls the printing panel through use of two dimensional planar slice data. Such slice data is used to address electrodes that correspond to points in the slice image. When the printing panel is brought close to a flat powder bed, a static electrical field at each addressed electrode attracts particles to the electrode's surface. The powder image on the printing panel electrodes is then placed over a substrate and the powder image is released to the substrate by applying a reverse polarity voltage to the electrodes. Multiple applications of powder image layers, with intervening fixing of each image layer, enables a three dimensional object to be rapidly constructed.
