| 101 | Apparatus for granulating thermoplastic strands | US33994773 | 1973-03-09 | US3837584A | 1974-09-24 | LEHR H; SWARAT W |
| In an apparatus for granulating thermoplastic strands there is provided a feeding device which, at its downstream end is interlocked with a comminuting device. The strands are advanced by cooperating conveyor belts along a supply path in the feeding device and are introduced into the comminuting device. In the feeding device and in the granulating device there is contained a liquid coolant which has a uniform liquid level and in which the cooperating portions of the conveyor belts are submerged to ensure that the strands are comminuted in a condition in which their outer surface is already hardened, while their interior is still soft.

| 110 | Device for recycling mixed plastic waste, a blade system for said device and a method for recycling mixed plastic waste | US14299540 | 2014-06-09 | US20150258713A1 | 2015-09-17 | Andrus VALDMAA; Aivo KÄSNAR; Aarne SAAREVÄLI |
| A blade system for device for recycling mixed plastic is disclosed. Furthermore, a device and a method for recycling unidentified, unclean, and unsorted mixed plastic into reusable plastic mixture is disclose. The present solution allows the recycling of mixed plastic waste outdoors, both in warm and cold climate conditions. In the course recycling mixed plastic waste the mixed plastic waste is taken to a melting temperature, at which the mixed plastic waste is mixed in a molten state, and the organic and bacterial material is destroyed during the thermal processing. After the melting, mixing and thermal processing of the mixed plastic waste, the compaction process of the molten mixed plastic waste is performed. Volume compacting is performed, and the mass of mixed plastic waste in a molten state is rapidly cooled down, crushed, after-cooled and homogenized. | ||||||
| 111 | CELLULOSIC MICROPOWDER PRODUCTION SYSTEM | US13839472 | 2013-03-15 | US20140265002A1 | 2014-09-18 | Seiji HATA |
| An improved process is provided for reducing cellulosic biomass into air suspendable micropowder. Although the process is particularly suitable for processing empty fruit bunches of oil palms, it is adaptable to most cellulosic biomass. The incoming biomass has a water content of around 50% and is reduced to centimeter scale pieces by a chipper or similar device. These pieces are then processed by a tandem line of four pairs of grooved rollers each successive roller having a larger number of grooves. This process squeezes moisture from the biomass and reduces the material into millimeter scale pieces. After an optional drying stage, the material is fed into a terrace line of three or four essentially smooth rollers which squash the material and reduce the particle size into a micrometer scale. Finally, the material is suspended in an air stream and fractionated by a cyclone and bag filter system. | ||||||
| 112 | Thermally insulated die plate assembly for underwater pelletizing and the like | US13353030 | 2012-01-18 | US08708688B2 | 2014-04-29 | Michael A. Fridley |
| An insulated die plate assembly for use in underwater pelletizing and other granulation processes includes a thin, continuous air chamber formed across the plate assembly generally parallel to the die face such that the heated upstream portion of the die plate assembly is thermally insulated from the downstream portion. The air chamber is atmospherically equilibrated by venting the air chamber to the atmosphere. The plurality of extrusion orifices, either individually or in groups, are formed in extrusion orifice extensions that extend through the insulation chamber so that the process melt to be granulated can pass therethrough. The orifice extensions and the components forming the air chamber around the orifice extensions channel heat along said extensions to maintain the process melt therein at a desired temperature, to help rigidify the die plate assembly and to better seal the air chamber. | ||||||
