  • Patent number: 9573104
    Abstract: Method of spray-drying a high-viscosity fluid, e.g. comprising a food product. The method comprises providing a nozzle plate wherein at least one nozzle is provided, said nozzle plate having an inner main surface and an outer main surface. The method comprises providing the high-viscosity fluid in a reservoir that is in fluidum connection with the at least one nozzle. The method comprises pressurizing the high-viscosity fluid in the reservoir, wherein the fluid flows, as a result of said pressurizing, towards the nozzle plate, thus creating a pressure difference over the at least one nozzle so that the fluid flows out of the at least one nozzle, thereby passing the outer main surface after passing the inner main surface. A cross-sectional area of the at least one nozzle in the inner main surface exceeds a cross-sectional area of the at least one nozzle in the outer main surface.

  • Patent number: 9573324
    Abstract: Systems and methods for producing a dense, well bonded solid material from a powder may include consolidating the powder utilizing any suitable consolidation method, such as explosive shockwave consolidation. The systems and methods may also include a post-processing thermal treatment that exploits a mismatch between the coefficients of thermal expansion between the consolidated material and the container. Due to the mismatch in the coefficients, internal pressure on the consolidated material during the heat treatment may be increased.

  • Patent number: 9555556
    Abstract: Polymer pellets are formed using air to influence the separation of polymer from a polymer melt. In accordance with one or more embodiments, a polymer material is extruded through a nozzle to form a polymer melt extending from the nozzle. A non-uniform thickness is generated in the polymer melt using a gas or gasses to apply a drag force to the polymer melt. This drag force reduces a thickness of a portion of the polymer melt adjacent the nozzle, and the polymer melt is fractured into discrete droplets at the reduced thickness. The discrete droplets are then solidified to form pellets.

  • Patent number: 9539765
    Abstract: In a method for discharging a volume flow consisting of successive drops to produce a three-dimensional object of solidifiable material present in a fluid phase, the fluid phase of the material is introduced into a material storage means. A pressure (p) is applied to the fluid phase, in order to discharge the material in drops out of a cyclable outlet opening to build up the three-dimensional object in a construction chamber. A method is provided for achieving a constant, discontinuous volume flow by the pressure (p) being regulated via a closed-loop control in the event of a change in the viscosity of the fluid phase of the material, while maintaining the other process parameters, to achieve a predetermined drop size. The pressure is applied by a conveying element, the average displacement velocity of the conveying element per discharged drop being converted as a measured variable into the control variable for the closed-loop control.
