The Screen Sizer effectively sizes round produce in a continuous process. It is a modular alternative to the Lift Roller Sizer. The Screen Sizer separates produce into two sizes. It has a rotating screen with holes at a set size. Produce is fed onto the screen and small produce falls through the holes while larger produce is carried to the outfeed. This process is aided by mechanical shakers that gently vibrate the produce on the screen. Multiple Screen Sizers can be placed in a row, each with slightly larger screen holes than the one before it, to separate produce into additional sizes.
