Described are an apparatus for generating and collecting nanospray reactive droplets and a method for analyzing a protein digestion. The apparatus includes a capillary, counter electrode, collection vessel, electrostatic lenses, and voltage control module. The capillary receives a mixture that includes a protein and an enzyme and has an outlet disposed in the aperture to dispense the mixture. The collection vessel has a concave surface to receive a nanospray plume emitted from the capillary outlet. The counter electrode and electrostatic lenses are disposed along a nanospray path defined between the capillary outlet and the collection vessel. Each electrostatic lens is formed of an electrically conductive plate having an aperture therein to pass a nanospray reactive plume. The voltage control module is in electrical communication with and is configured to independently control the voltage of the capillary, the counter electrode, the collection vessel and each of the electrostatic lenses.

An electrodischarge apparatus has a nozzle that includes a discharge chamber that has an inlet for receiving a liquid and an outlet. The apparatus has a first electrode extending into the discharge chamber that is electrically connected to one or more high-voltage capacitors. A second electrode is proximate to the first electrode to define a gap between the first and second electrodes. A switch causes the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes from the nozzle ahead of the plasma bubble.

A voltage assisted painting system includes a housing, at least one nozzle, and at least one electrode. The housing has a conduit for receiving paint from an external source into the housing. The at least one nozzle is disposed in the housing. The at least one nozzle has an inlet that is fluidly connected to the conduit to receive paint from the conduit. The at least one nozzle has an outlet that dispenses paint. The at least one electrode is provided at the housing at a location downstream of the inlet with respect to the conduit. The at least one electrode is configured to generate a magnetic field in the vicinity of the outlet.

The present invention generally relates to an electrostatic coating system for spraying a stream of particles onto a medium, and in particular to a system comprising one or more apparatuses equipped with a powder coating suspension device. What is also contemplated is the use of a powder management system configured to supply predetermined powdered and air mixtures to the apparatus and a controller configured to adjust parameters of operation of both the apparatus and the powder management system. The present disclosure relates to an in-line industrial device able to coat paint, starch, thermoplastic materials, or any other powder material onto a medium by successively controlling a plurality of parameters.

The subject invention is an electrostatic plant watering system for the delivery of water and nutrients to the roots of plants. The system provides water or another fluid from a fluid source or container using a pump. The pump provides a pressurized fluid at a constant flow rate through a nozzle at a low pressure, which sprays a fine mist of particles through a conductive metallic ring that is electrically charged by a voltage source. As the fluid particles pass through the center of the electrically charged ring, the particles themselves become charged, allowing them to attach to the roots of a target plant positioned at a selected distance away from the electrostatic plant watering system.

The present invention provides an electrostatic spraying device and an electrostatic spraying method. The electrostatic spraying device includes: a high-voltage electrostatic generator configured for generating high-voltage static electricity and including a positive output terminal and a negative output terminal; a charging electrode connected to the positive output terminal or the negative output terminal of the high-voltage electrostatic generator and configured for directly contacting a liquid to be sprayed and applying electrostatic charges to the liquid to be sprayed; and an ionizing emitting electrode connected to the negative output terminal or the positive output terminal of the high-voltage electrostatic generator and configured for ionizing the surrounding air to realize an ionizing grounding.

A dry powder coating apparatus for coating pharmaceutical solid dosage forms includes a housing; a drum coater; a powder coating system; a liquid spray system; a ventilation system; a heating system; a touch screen control panel; and an operation box. The drum coater may have a truncated cone on both sides, in which one side is opened and another side is closed. The drum coater is horizontally placed inside the operation box along its axis and fixed on a rotatable shaft and a motor drives the rotatable shaft and rotates the drum coater about its own axis.

An electrostatic spray drying system comprising an electrostatic spray nozzle for directing electrically charged liquid into a drying chamber, a drying gas inlet from which drying gas is simultaneously directed, and a conical powder direction plenum for receiving drying gas and entrained dried powder for direction to a filter containing powder separation plenum via a connecting conduit. The powder direction plenum and connecting conduit each have a surrounding water jacket heat exchanger through which cooling water is directed for cooling the drying gas and powder below damaging temperatures prior to entry into the powder separation plenum. The powder separation plenum has a return line for redirecting separated drying gas to the drying chamber through a condenser, blower, and heater for reuse in the system, with condensed water being selectively redirected to the inlet of the powder direction plenum heat exchanger and/or to the cooling water supply.
