Abstract: Methods of simultaneously forming feed particles of different densities involves extruding a heated feed through an extruder having an extruder die defining a plurality of die openings. A first plurality of the die openings comprises a land length that is at least two times as long compared to a diameter of a respective die opening. A second plurality of the die openings comprises a land length that is equal to or less than a diameter of a respective die opening. Extrusion through the first plurality of the die forms extruded ribbons with a first density, while extrusion through the second plurality of the die openings forms extruded ribbons with a second density that is lower than the first density. The method proceeds by cutting the first and second plurality of extruded ribbons to simultaneously form feed particles of the first and second densities.

Abstract: A method for identifying an angle of roll for a multi-nozzle extruder includes moving the extruder in a first process direction to form a first set of swaths of extrusion material using two nozzles in the extruder and moving the extruder in a second process direction to form a second set of swaths of extrusion material. The method further includes identifying a location of one nozzle relative to the other nozzle in two dimensions based on cross-process direction distances between the first and second sets of swaths and identifying the angle of extruder roll for the extruder based on the location of the one nozzle and a predetermined geometry of the extruder.

Each of the polymeric ribbons and strands has a length and width, with the length being the longest dimension and the width being the shortest dimension. The polymeric ribbons have a height-to-width aspect ratio of at least five to one, a major surface that is intermittently bonded to only one polymeric strand, and a height greater than the height of the one polymeric strand. An extrusion die and method useful for making the polymeric netting are also disclosed.

Abstract: The present invention is directed to a process for producing a modified olefin polymer in an extruder having a feed zone, a melting zone, optionally a mixing zone and optionally a die zone, (A) introducing a stream of an olefin polymer into the feed zone of the extruder; (B) introducing a stream of a free radical generator directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (C) introducing a stream of a functionally unsaturated compound directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (D) extruding the mixture in the extruder at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder; and, optionally, (G) passing the melt of the modified olefin polymer through the die zone to a pelletiser.

Abstract: The method and system produces a high-moisture aquatic feed that is stable in water and has a texture that more closely resembles naturally-occurring aquatic feedstocks. The system includes a “tempering unit” that is structured to allow an operator to control the temperature of a low-carbohydrate high-moisture extrudate after the extrudate leaves a conventional extruder. As the extrudate flows through a tubular matrix within the tempering unit, expansion of the extrudate is controlled to produce the high-moisture water-stable aquafeed.

Abstract: 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.

Abstract: A compression system includes a compression device and a controller. A treated material is pressed longitudinally through a compression chamber by simultaneously applying a lateral pressure and a two-dimensional cross-section compression which includes a pressure applied in a direction traverse to a direction of transport and a pressure applied in a direction parallel to the direction of transport. The controller controls the two-dimensional cross-section compression applied to the treated material such that, during compression, liquids in the treated material migrate to the outer surface of the treated material upon reaching the outlet orifice.
