Abstract
A sizing table for a product such as potatoes which sorts product according to its size includes a frame which supports a plurality of horizontally extending parallel rotary spindles. A first group of the spindles supports tapered rollers while a second group of spindles interposed in alternating fashion with the first group includes variable pitch augurs. A motor imparts rotary motion to both groups of spindles and drives the product down the table. When the pitch of the augur combined with the distance from the augur to the spindles increases sufficiently, product is allowed to drop through into selected bins or conveyors placed below the table.
