Abstract: A centrifugal dryer (10) for removing surface moisture from pellets of resin material having a diameter generally ranging between approximately 0.015 to approximately 0.25 inches received from an underwater pelletizer. In one embodiment of the present invention, the dryer is constructed with smaller dimensions enabling it to effectively operate at low volume rates and be easily assembled and disassembled to facilitate cleaning and replacement or interchange of components with its overall size enabling it to be effectively used in small applications. In other embodiments of the present invention, the dryer is constructed with larger dimensions enabling it to effectively operate at high volume rates for use in commercial applications.

Abstract: A dryer for removing surface moisture from a pelletized product and more specifically a dryer which is constructed with dimensions enabling it to effectively centrifugally remove surface moisture from pellets of resin material received from an underwater pelletizer. The dryer is capable of operating at very low rates and easily cleaned with its overall size enabling it to be effectively used for small operations, especially laboratory applications.

Abstract: A sight glass apparatus and method limiting external pressures on the sight glass. The sight glass apparatus has a pair of flanges wherein each of the flanges includes a tubular top portion which abuts the respective pipes. The tubular top portion includes a circular cut-out for providing a victaulic type connection for a clamping means to clamp to the respective pipes and a conical section which tapers into an annular rim section having a plurality of apertures wherein a bottom portion of the annular rim includes a center aperture being co-axially aligned when mounted to the pipes. An O-ring is mounted in a recess with a cylindrical glass tubing for observing the fluid or the like. The sight glass apparatus further includes machine precisioned shoulder studs with threaded ends. The ends protruding through the apertures of each of flange when connecting the sight glass apparatus together.
