The NOVA sieve is designed to eliminate common issues by increased simplicity. Through this simplified design, the number of required components is reduced, offering improved durability and reduced risk of contamination over the course of your sieve stack’s operating life. The use of the metal insert frame and combination cleaners reduces overall sieve height, which allows for more sieves or deeper sieves that allow increased material flow in the sifter compartment. During operation, the high-performance cleaners clean both pan and screen simultaneously, making the NOVA sieve a superior choice for high-capacity operations that do not sacrifice flow quality.

NOVA Sieve
The NOVA design uses a unique combination screen and pan cleaner available with plastic knobs or brush tufts. With a combination screen, and pan cleaner slides added to the stainless-steel pan, no backwire is required. Specialized NOVA cleaners are held in place by the sides of the aluminum lift-out tray, which additionally eliminate the need for pan cleaner retaining pins. NOVA Sieves are available in natural wood, laminated wood, and food grade plastic. All trays are aluminum lift-out trays with glued-on screens.
- The use of only one NOVA cleaner per tray compartment is a superior method to create more sanitary conditions.
- The aluminum lift-out frame offers a thinner profile than wooden frames, increasing net screen area per stack.
- The aluminum insert tray provides a stable and wear-resistant support for screen attachment, resulting in optimized conditions for screen tension longevity.
- Improved sanitation and reduced risk of product contamination with use of glue-on attachments over stapled attachments.
- Eliminated backwire reduces hazard of deterioration or fastener loss.
- Unique engineering overall reduces maintenance requirements.
- Space-effective, thinner design allows either increased number of sieves, improving separation efficiency, or deeper sieves, increasing conveying capacity.
- Improved product flow.
