Described herein are industrial application systems for treating (e.g., forming protective coatings on) produce, agricultural products, or other items. An exemplary application system can include a bed comprising a plurality of rollers, one or more sprayers over a first portion of the bed, one or more blowers over a second portion of the bed, a mixing system configured to prepare a mixture comprising a coating agent in a solvent, and a liquid delivery system connected inline between the mixing system and the one or more sprayers. Items placed on the bed can have the mixture applied to their surfaces via the one or more sprayers, after which the one or more blowers can at least partially remove the solvent from the surfaces of the perishable items, thereby causing the protective coatings to be formed over the perishable items.

Some embodiments of the invention belongs to a technical field of NdFeB magnet processing, and mainly relates to a device and method for improving the coercivity of ring-shaped NdFeB magnet. A layer of heavy rare earth coating is sprayed on the inner and outer surfaces of the ring-shaped NdFeB magnet by the device, and then the ring-shaped NdFeB magnet sprayed with the heavy rare-earth coating is subjected to diffusion treatment to improve the coercivity of the ring-shaped NdFeB magnet. The invention uses heavy rare earth slurry as the diffusion source, combined with spraying technology, can quickly and uniformly cover a layer of heavy rare earth coating on the inner and outer surfaces of the ring-shaped NdFeB magnet, and the coercivity of the ring-shaped NdFeB magnet is improved after heat treatment.

The double-layer vacuum chamber and the process chambers are arranged in two juxtaposed rows in a Y-direction transverse to the Z-direction. A feed lifting mechanism is disposed in one of the double-layer vacuum chamber 3 and the process chambers, and includes a feed lifting seat movable in the Z-direction. A plurality of first conveying devices are respectively disposed in the other ones of the process chambers for conveying the carrier. A method for coating a multilayer film on at least one object to be coated carried by a carrier is also disclosed.

The present invention discloses a method and an apparatus for spray painting an annular object. The annular object to be spray painted is placed and positioned on a loading tray disposed on a machine station and transported by a transporting mechanism along a spray painting path of the machine station. A self-rotation mechanism is turned on to automatically rotate the loading tray and the annular object to be spray painted. An air gun and a spray gun are turned on to remove dust on a disk surface of the annular object and spray paint the disk surface of the annular object to form a protection layer thereon.

Coating apparatus (20) includes a pair of juxtaposed bodies (22, 24, 112, 114, 112a, 114a, 138, 140) defining a nip region (30, 126, 126a, 150) therebetween, with each presenting a periphery (26, 28, 116, 118, 116a, 118a, 144, 146) and being rotatable in opposite directions, respectively. The peripheries (26, 28, 116, 118, 116a, 118a, 144, 146) of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) are provided with a series of indentations (32, 120, 120a, 148). Liquid coating material is directed onto the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) through an outlet (100, 110, 158) during rotation of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140). This generates an adjustable spray or fog flow pattern (108) for effective coating of a substrate.

Coating apparatus (20) includes a pair of juxtaposed, cylindrical bodies (22, 24) defining a nip region (30) therebetween, with each presenting a periphery (26, 28) and being rotatable in opposite directions, respectively. The peripheries (26, 28) of the bodies (22, 24) are provided with a series of laterally extending notches (32), optionally oriented to provide chevron patterns (68) with apices (32a) and diverging legs (70a, 70b); the patterns (68) are positioned so that the apices (32a) first pass through the nip region (30), with the legs (70a, 70b) in trailing relationship. Liquid coating material is directed onto the bodies (22, 24) through an outlet (100, 110) during rotation of the bodies (22, 24). This generates an adjustable spray or fog flow pattern (108) from the apparatus (20) for effective coating of a substrate.
