Abstract: The electrospray device comprises a sprayer comprising a sprayer body and nozzle, and a partition positioned vertically and coaxially with the sprayer. The sprayer body is provided with a swirl generator for generating a swirling air stream, and a power supply connected between the nozzle and the partition, to apply voltage to the nozzle and the partition. The electrospray device may be part of a fluidized bed apparatus comprising a product container, a lower plenum base, an air distribution plate resided therebetween. When the power supply applies voltage in opposite polarities to the nozzle and the partition, the fluidized bed apparatus is used for coating particles; and when the power supply applies voltage of the same, the fluidized bed apparatus is used for spray-drying a solution. The electrospray device uses an electromagnetic hydrodynamic method to improve the performance of the fluidized bed apparatus and optimize the process of product.

Abstract: The disclosure relates to ultrahigh efficiency spray drying systems and processes, utilizing induction of localized turbulence in a drying fluid flow stream to produce spray dried product, having particular utility for low temperature spray drying operations. In a specific implementation, a method of processing a spray dryable liquid composition to form a spray dried product includes the steps of: generating a spray of the spray dryable liquid composition; contacting the spray of spray dryable liquid composition in a spray drying contact zone with a stream of primary drying fluid; injecting pressurized secondary drying fluid into the stream of primary drying fluid in the spray drying contact zone at multiple loci thereof to provide localized turbulence at said multiple loci; and recovering the spray dried product from the spray drying contact zone. Systems of the present disclosure are effective in achieving high-rate production of dry powder spray dried products, with substantially reduced capital equipment costs, energy requirements, and operating expenditures.

Abstract: A surgical spray instrument is disclosed comprising a main body connectable to a transfer tube; a propellant actuator for selectively releasing propellant from the main body and along the transfer tube and out through a distal end thereof. An ion emitter is arranged along the tube, the ion emitter having an ion emission zone. This enables the directed and concentrated delivery of therapeutic, pharmacological and diagnostic agents to tissues inside or outside of the body. There is further disclosed a surgical assembly for enabling uniform deposition of a particulate material to a surface of an intracorporeal cavity of a patient. The surgical assembly comprises an ion emitter; a dispenser having an outlet locatable within the cavity and for dispensing the particulate material therefrom, and a processor for determining a location of the ion emission zone of the ion emitter in dependence upon the position of the outlet of the distributor within the cavity to provide for the uniform deposition.

Abstract: A method of stripping, prepping and coating a surface comprises first stripping the exiting coating from a surface, using continuous or pulsed fluid jet, followed by prepping the surface by the same fluid jet. The method also provides entraining particles into a fluid stream, if desired to generate a particle-entrained fluid stream that is directed at the surface to be stripped and prepped. The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to coat the surface. The particles form both mechanical and electronic bonds with the surface.
