  • Patent number: 11130258
    Abstract: A system for processing material, for example recycled material, comprises a compacting device (101) for compacting the material and a treatment device (102) for agglomerating, pelletizing, or nozzle-extruding the compacted material. The compacting device comprises a compacting chamber (103) and a compacting element (104) that is moveable in the compacting chamber to reduce the volume of the compacting chamber so as to compact the material to be delivered to the treatment device. As the material is compacted prior to being agglomerated, pelletized, or nozzle-extruded, supply of the material to the treatment device can be more reliable especially when the material is chopped waste plastic or other fluffy material including much air. Furthermore, efficiency of the agglomeration, pelletizing, or nozzle-extruding is improved because the compacting increases density of the material prior to the agglomeration, pelletizing, or nozzle-extruding process.

  • Patent number: 10759106
    Abstract: A cutter assembly includes a rotatable cutting head carrying outwardly extending cutter blades, as well as a rotatable drive hub and interconnected spring housing. The drive hub has a bearing housing, whereas spring housing includes coil spring. The spring housing is operably coupled with the cutting head, in a manner such that the spring exerts an unrestrained force against the cutting head and blades so that there is unrestrained movement of these components toward the outlet face of an extruder die plate. Consequently, there is a substantially constant self-adjusting force exerted on the cutter and blades against the plate, which promotes cleaner cutting of extrudate, even in the event that there is a degree of misalignment between the cutting edges and the outer surface of die plate. This arrangement lengthens the service life of the blades and the die plate.

    Abstract: Insulated shipping container with rabbet-joint side panels and the procedure for making the same. The insulated shipping container consists of an outer box and six insulated panels. The outer box is made of corrugated fiberboard. The insulated panels are made of expanded polystyrene foam with a thickness of at least 2 inches. The panels are cut with a hotwire machine and the rabbet-joint design locks the side panels in place, which gives the insulated container superb structural and thermal integrity. The box is assembled with a specific H-shape taping and the six panels are inserted to form the insulated container. The invention is the first to meet the packaging requirements of postal carriers and their insurance underwriters. The cost-effective manufacturing process allows for multiple container sizes without additional setup expense, which lowers the cost of shipping affected by dimensional weight versus actual rate shipping rates by the carriers.

  • Publication number: 20150021807
    Abstract: An apparatus and process to maintain control of the temperature of low-melting compounds, high melt flow polymers, and thermally sensitive materials for the pelletization of such materials. The addition of a cooling extruder, and a second melt cooler if desired, in advance of the die plate provides for regulation of the thermal, shear, and rheological characteristics of narrow melting-range materials and polymeric mixtures, formulations, dispersions or solutions. The apparatus and process can then be highly regulated to produce consistent, uniform pellets of low moisture content for these otherwise difficult materials to pelletize.

  • Patent number: 8877107
    Abstract: The present invention relates to increasing the molecular weight during a thermal treatment of polyester in combination with a latent heat granulation. With the newly-developed method, an SSP (Solid State Postcondensation) can be directly combined with an underwater granulation. The method differs from a conventional solid state postcondensation by an increase in the molecular weight being possible without additional heat input and hence only by using the residual heat and the crystallization heat present. A characterizing element is improved water separation and dehumidification during the granulation. Only in this way is an increase in viscosity possible even with a small granulate of an average particle weight less than 20 mg.

  • Publication number: 20140319715
    Abstract: A method for producing non-expandable pellets can include introducing a vinyl aromatic polymer to a pelletizer (L). The pelletizer (L) can have a die plate having a holes of large diameter. During the start-up of the production of the non-expandable pellets, pellets can be produced in the pelletizer (L). When the polymer flow rate is in the operating range of the pelletizer (S), the introduction of the vinyl aromatic polymer can be switched from the pelletizer (L) to the pelletizer (S). The pelletizer (S) can be operated at conditions effective to produce the non-expandable pellets. The pelletizer (S) can have a die plate having holes of small diameter. The non-expandable pellets can be recovered from the pelletizer (S), and the pellets can be recovered from the pelletizer (L).

  • Publication number: 20140070447
    Abstract: An apparatus and method for the pelletization of waxes, wax-like and other materials having a sharp melt point include a vessel for forming the wax into a hot molten material. A heat exchanger then cools the molten wax to a temperature just above its melt temperature. The cooled liquid wax is fed to an extruder which further reduces the temperature and mixes the liquid wax into a thoroughly mixed extrudable solid wax. The solid wax is then extruded through die orifices of a die plate into a cutting chamber, and a rotary cutter cooperating with the die face of the die plate cuts the extruded solid wax strands into pellets. The die plate, cutting chamber and rotary cutter can have the same structure as an underwater pelletizer, but operating without water or liquid as a dry face pelletizer. The thus formed wax pellets drop out of the cutting chamber by gravity through an opening in the bottom thereof.
