A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a rotatable drum that receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube at least partially disposed within the drum is configured to introduce a flow of air into the drum.

Tumbler systems and methods

A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a housing for rotatably supporting a removable screened drum on a plurality of rollers. The drum receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube disposed within the drum is configured to direct air through the screens to an air blower intake positioned outside of the drum.

An embossed screen having raised deflector elements on the internal surface is provided for a centrifugal pellet dryer. The deflector screen is formed as an integral structure, eliminating the need for separate deflector components secured by fastening elements along with the associated risks such as loosening or separation of the strip and contaminate build-up between the strip and the screen. The embossed deflector screen effectively deflects the pellets back toward the rotor where the pellets are reengaged with rotor energy, resulting in increased dryer efficiency and flow rate. The embossed deflector screen also enhances the overall structural strength of the screen, reduces manufacturing costs and prevents pellet entrapment that can lead to contamination in future runs.

A centrifugal dryer ( ) 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.

Centrifugal pellet dryer

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.

Improvements in centrifugal pellet dryers and more particularly to improvements in the rotor structure which includes a shaft, pellet lifter assemblies and supporting spiders which support the pellet lifter assemblies from the shaft. Each spider is made of a one-piece plate laser cut for strength, balance and simplicity. Mounting of the pellet lifter assemblies on the spider, and the spider on the shaft, are configured for easy assembly and maintenance.

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. Therefore, the machined precision shoulder stud bears most of the sealing pressure and limits the movement of the flanges towards each other so that the axial pressure exerted on the cylindrical glass tubing is minimal.
