CONTINUOUS FLOW DRYER FOR TREATING BULK MATERIAL
20180003439 · 2018-01-04 ·

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.

VIBRATION ISOLATING INSERT FOR A PIPE CLIP AND METHOD FOR MANUFACTURING SUCH AN INSERT

A vibration-isolating insert for a pipe clip is adapted to bear against an inner circumference of a substantially annular pipe clip body and ultimately, in use, to be positioned between the outer circumference of a pipe and the pipe clip body. The vibration-isolating insert includes an elongate strip of vibration-isolating material which has a pipe facing side and a pipe clip facing side. The strip of vibration-isolating material has adjacent either lateral edge thereof a series of discrete exposed hooks of plastics material which is more rigid than the vibration-isolating material. The hooks protrude relative to the pipe clip facing side of the strip of vibration-isolating material.

OPTICAL SHEET FORMING DEVICE AND OPTICAL SHEET FORMING METHOD

An extruding unit, a forming roll unit and a thick portion forming mechanism are provided. The extruding unit has an ejecting slit which ejects sheet-shaped molten resin.
