Continuous heating, cooling & predrying.When Coperion Waeschle GmbH in Germany (U.S. offices in Houston) introduced its Bulk-X-Change continuous tubular tubular /tu·bu·lar/ (too´bu-lar) 1. shaped like a tube. 2. of or pertaining to a tubule. tubular 1. pertaining to renal tubules. 2. pertaining to fallopian tube. heat exchanger heat exchanger Any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications, one fluid needs to be heated and another cooled, a requirement economically accomplished by a heat exchanger. for solids at the K 2004 show in Dusseldorf, the firm wasn't sure where it might fit in polymer processing. (All 20 commercial applications have been in minerals and fillers.) The firm thought it might be used primarily for cooling--e.g., of PET chips after solid-stating. But the first plastics application--being installed now in Brazil--is for preheating PET chips before fiber spinning, and Waeschle sees more interest in heating/drying than cooling. With some modification, for example, the unit could predry PET. Each heat-exchange tube is custom designed for plant height, throughput The speed with which a computer processes data. It is a combination of internal processing speed, peripheral speeds (I/O) and the efficiency of the operating system and other system software all working together. 1. , material, and pellet pel·let n. 1. A small pill; a pilule. 2. A small rod-shaped or ovoid mass, as of compressed steroid hormones, intended for subcutaneous implantation in body tissues to provide timed release over an extended period of time. or chip size. Material enters the vertical tube through a special feeder feeder abbreviation for self-feeders. Used in feeding groups of animals at intervals of several days. Feed has to be dry and comminuted so that it will run down the spouts from the hopper into the troughs. plate (right). The tube has a flow valve at the bottom. Air is forced upward through the chips to remove heat and some moisture. Tel: (281) 449-9944 * PTDirect: 789LZ |
