Patent number: 9943817Abstract: An apparatus for continuous pelletization and crystallization of a polymer includes a unit for forming a polymer pellet material and cooling the pellet material in a liquid cooling medium. An after-connected drying unit has an exit opening for exporting gas and a crystallizer for crystallizing the pellet material. The crystallizer communicates via a connection line with the pre-connected unit for separating the liquid cooling medium from the pellet material and drying the pellet material. The crystallizer communicates with an inert gas tank, whereby the pressure in the crystallizer can be increased relative to the pressure in the drying unit. A related process is also disclosed.Type: GrantFiled: September 20, 2013Date of Patent: April 17, 2018Assignee: POLYMETRIX AGInventors: Andreas Christel, Brent Allan Culbert, Fernando Eusebio

Patent number: 9039948Abstract: The invention relates to a method and a device for producing and treating plastic pellets. According to said method, a melt of the plastic material is granulated to give pellets, the pellets are cooled in a cooling fluid, the pellets are separated from the cooling fluid and the pellets are crystallized. The device according to the invention is characterized by comprising a control unit which monitors the crystallization step and controls the method in such a manner that, in case of a disturbance of crystallization, the pellets are supplied to an intermediate storage alter separation of the pellets from the cooling fluid and, as soon as the disturbance is removed, the pellets temporarily stored in the intermediate storage are supplied to crystallization and are crystallized.Type: GrantFiled: March 11, 2013Date of Patent: May 26, 2015Assignees: Rieter Automatik GMBH, Buhler Thermal Processes AGInventors: Frank Glöckner, Fernando Eusebio, Brent Allen Culbert, Franziska Morganti

Patent number: 8562882Abstract: The invention relates to a method for the continuous production of semicrystalline polycondensate pellets. Said method comprises the following steps: producing a polycondensate material; shaping polycondensate pellets and solidifying the polycondensate melt in a liquid cooling medium, wherein the shaping of the pellets can be carried out prior to or after solidification; separating the pellets from the liquid cooling medium once the polycondensate pellets have cooled down to an average temperature that lies within the crystallization temperature range of the polycondensate; and crystallizing the pellets in a treatment chamber, the treatment gas being led in said treatment chamber in a countercurrent to the polycondensate pellets, the flow rate of the treatment gas being above the incipient fluidization point of the polycondensate pellets and the polycondensate pellets having a narrow dwell time spectrum in the treatment chamber.Type: GrantFiled: December 5, 2007Date of Patent: October 22, 2013Assignee: Bühler AGInventors: Fernando Eusebio, Brent Allan Culbert, Andreas Christel, Peter Locker

Patent number: 8147738Abstract: The invention relates to a method for the production of granulate grains of polymers from thermoplastic polyesters or copolyesters from a polyester melt using an extrusion granulator. The polyester melt is fed to nozzles of the extrusion granulator and then, with draw-in rollers, to the granulation device via an extraction section as extrusions exiting from the nozzle, wherein, e.g., an extrusion extraction speed is set by the draw-in rollers. The invention also relates to an improved extrusion granulator according to the invention having a wave device between the nozzles and the extraction channel, and granulate grains produced according to the method according to the invention.Type: GrantFiled: November 12, 2007Date of Patent: April 3, 2012Inventors: Jaroslaw Boczon, Andreas Doll, Sven Fenchel, Brent Allan Culbert, Fernando Eusebio, Franziska Morganti
