Iso-Flo® Clearing Grader

The Iso-Flo® Clearing Grader’s double-deck screens separate peas or small berries such as cranberries or blueberries from debris as the product is conveyed. The upper deck eliminates pods, sticks, and similar material, and the slotted lower deck removes small, immature product, and fruit skins.  The clearing feature periodically raises the frequency of operation for a brief “pulse” that clears the screens of binding particles.

Simple to install, operate, clean, and maintain, the Clearing Grader has all Iso-Flo® features and benefits. It is quiet and reliable, operates at high capacity, and uses quick-change Vector-Lock™ screen clamps.

Today, more than 25,000 Iso-Flo units are in use worldwide. Smart Shaker® advancements including real-time SmartArm™ monitors, StrongArm™ spring arms, Forté™ controls and Predictive Maintenance programs provide up-to-the-minute opportunity for even more efficiency and long life.  This global record of superior reliability is backed by Key’s industry-leading 5-year warranty on all Iso-Flo conveyors, maximizing long-term return on your investment.
