A continuous flow dryer system according to various embodiments can include a source for supplying a material to be treated having a high moisture content, such as a distiller wet grain, a profile screw compression dryer, a profile screw, and a drive coupled to the profile screw for axially rotating the profile screw. The profile screw compression dryer includes an inlet for receiving the material for drying, which is fed therein in a controlled manner. The profile screw is provided within the housing of the dryer. The profile screw has a diameter that increases in dimension in a direction away from the inlet for increasing the compressive force applied to the material to assist with drying as the profile screw rotates and moves the material longitudinally along the profile screw to produce a final product, for example, a distiller dried grain for use as an animal feed.

A method enabling the selection, modification and/or creation of polymer materials which can provide improved response to the application of local shear and/or extensional deformation inside the polymer melt in manufacturing technologies including injection molding, injection stretch blow molding, direct injection, extrusion blow molding, sheet extrusion, thermoforming, etc., is provided. A method for manufacturing a polymer article includes injecting or extruding molten polypropylene, polyethylene or polyester based polymer for converting it into semi-final shape while applying shear and/or extensional deformation on the polymer melt. Applying shear and/or extensional deformation on the polymer melt includes selectively modifying the flow path of the molten semi-crystallizable polymer as a function of local pressure profile over at least part of the flow path. Local pressure profile is a function of optimized response of the polymer melt to the applied local shear and/or extensional deformation over at least the part of the flow path.

A method and apparatus for the pelletization of plastics and/or polymers, in which a melt coming from a melt generator is supplied via a diverter valve having different operating positions to a plurality of pelletizing heads through which the melt is pelletized. The plurality of pelletizing heads have different throughput capacities and are used sequentially for the start-up of the pelletizing process, with the melt first being supplied to a first pelletizing head having a smaller throughput capacity and then the melt volume flow being increased and the diverter valve being switched over such that the melt is diverted by the diverter valve to a second pelletizing head having a larger throughput capacity.

A system according to various embodiments can include a source for supplying a material to be treated, an extruder, at least two screws, and a drive coupled to the screws for axially rotating the screws. The extruder includes an inlet for receiving the material, which is fed therein in a controlled manner. The screws are provided within the housing of the extruder. The screws have a plurality of compression and release stages that create mechanical heat which is directly applied to the material to change the mechanical properties of the material thereby facilitating a conversion of a physical state of the material from a non-compactable state to a compactable state as the screws rotate and move the material longitudinally along the screws to produce a final product, for example, a feed tub for use as an animal feed.
