Featuring a three-bearing shaft that cantilevers for quick removal of internal components, according to Henry Alamzad, President of Kason. Vibration free operation and good structural support even under heavy load are achieved by external roller bearings located at the motor end of the shaft and on a hinged cover at the discharge end. When the hinged end cover is open, the shaft cantilevers on a third externally-mounted roller bearing located between the motor-end bearing and material feed point, allowing internal components to slide freely from the opposite shaft end.

By using the integrated Clean-In-Place spray balls the Centri-Shifter van be rapidly sanitised steam or cleaning solution. A durable construction of stainless steel allows good performance and cleaning characteristics. The Centri-Shifter complies to 3-A, FDA, BISSC, and other sanitary standards, and is equipped with a stainless steel motor.

The unit is intended for food, dairy and pharmaceutical applications requiring thorough wash-down, as well as general chemical applications involving frequent screen changes/inspections or runs of multiple materials with no cross contamination.

Dry or moist bulk solid material is gravity-fed into the horizontally-oriented cylindrical screening chamber fitted with heavy-duty wedgewire screen. A rotating helical paddle assembly accelerates the radial movement of particles against the screen causing on-size particles to pass through apertures in the screens and fall through a cone-shaped discharge chute. Oversize particles are propelled through the open end of the screen cylinder and ejected through a discharge spout. In addition to sifting and scalping of dry bulk materials, the screener can break up soft agglomerates and/or dewater moist solids or slurries.
