    A close-up of an electrospray device, with emitter tip in foreground pointing to the right. The jet of ionised spray is visible within the image. To simplify the discussion, the following paragraphs will address the case of a positive electrospray with the high voltage applied to a metallic emitter.

  3. Spray drying - Wikipedia

    en.wikipedia.org/wiki/Spray_drying

    The spray drying technique was first described in 1860 with the first spray dryer instrument patented by Samuel Percy in 1872. [citation needed] With time, the spray drying method grew in popularity, at first mainly for milk production in the 1920s and during World War II, when there was a need to reduce the weight and volume of food and other materials.

  4. Electrostatic coating - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_coating

    Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.

  5. Rotary atomizers - Wikipedia

    en.wikipedia.org/wiki/Rotary_atomizers

    Spray drying and spray painting are the most important and common uses of this technology. Many industries need to convert a large mass of liquid into a dispersion of small (micron-size) droplets (generate a spray). Some examples of this need are evaporative cooling, meteorology, printing, medical applications, spray combustion, coating, and ...

  6. Nano spray dryer - Wikipedia

    en.wikipedia.org/wiki/Nano_spray_dryer

    Nano spray dryers refer to using spray drying to create particles in the nanometer range. Spray drying is a gentle method for producing powders with a defined particle size out of solutions, dispersions, and emulsions which is widely used for pharmaceuticals, food, biotechnology, and other industrial materials synthesis.

  7. Electrostatic spray-assisted vapour deposition - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_spray...

    Electrostatic spray-assisted vapour deposition (ESAVD) is a technique (developed by a company called IMPT) to deposit both thin and thick layers of a coating onto various substrates. In simple terms chemical precursors are sprayed across an electrostatic field towards a heated substrate, the chemicals undergo a controlled chemical reaction and ...

    en.wikipedia.org/wiki/Spray_(liquid_drop)

    Spray drying [15] [16] is used to produce hundreds of food products, including instant coffee, powdered soups, and flavor concentrates. Coating of food products with flavorings and surface additives. Cleaning and sanitizing storage tanks, and process equipment single fluid nozzles are used to rinse and wash away materials.

  9. Flue-gas desulfurization - Wikipedia

    en.wikipedia.org/wiki/Flue-gas_desulfurization

    In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO 2-absorber. However, in dry injection or spray drying operations, the SO 2 is first reacted with the lime, and then the flue gas passes through a particulate control device.
