Kason Europe's ultrasonic, ultra-sanitary Vibroscreen 0.25in Separator with gap-free screen frames, quick-access vertical clamps, and Kasonic ultrasonic anti-blinding system separates bulk foods, pharmaceuticals, chemicals and other products prone to screen blinding and contamination into three particle size fractions.
Made of stainless steel with continuous large-radius weld seams ground and polished to 240-grit, the screener complies with 3-A, BISSC and FDA sanitary standards as well as ATEX and CE electrical standards.
The external, interlocking flange configuration of the screen frame envelops the support ring of the screen, allowing the screen’s wire mesh to extend to the interior walls of the frame. It eliminates the gap between the screen ring and frame wall of conventional screeners where material would otherwise collect.
The gap-free design is said to reduce the possibility of contamination due to bacteria growth, and improves sanitising efficiency, making it suitable for pharmaceutical, food and dairy applications.
The patented Kasonic anti-blinding device allows sifting of powders as fine as 25 microns (500 mesh) at high rates with no screen blinding. Single or multiple transducers (for large diameter machines) transmit ultrasonic frequencies to the screen surface in continuous or pulse mode, automatically adjusting power to maintain constant frequency as screen loads vary. Transducers operate with standard screens and are not fixed to the woven wire mesh, reducing re-screening costs significantly.
The Clean-In-Place design employs spray nozzles, rinsing solutions and/or steam for sanitising the interior of the screening chamber(s) without the need to open or disassemble the unit. The four-leg support stand with open base design and stainless steel wash-down motor enclosure provides complete access for thorough washdown of the unit’s underside and plant floor.
Available in diameters from 46 to 152cm, the unit is also offered with a second spout on the upper frame for continuous discharge of the overs fraction.
