In some mills the rice is passed through a second set of hullers. Bran reel.—The bran reel receives the product from the hullers and separates the rice from the powdery bran. This reel is com- posed of a large octagonal framework covered with fine wire screen, the square meshes of which are 14 per linear inch. The reel is set on a slight incline and its slow revolving motion takes the rice, which enters at the higher end, through its length of 9 feet in about 5 minutes. As the reel revolves, the rice con- stantly falls from side to side and forces the bran through the wire covering. Pearling cone.—The pearling cone, which has recently been in- troduced in many mills to supplement the work of the hullers, is essen- tially the same ma- chine that is used in the pearling of barley. The principal working part of the machine is a frustrum of a cone covered with a compo- sition stone; this is surrounded by a sieve mantle composed of close - meshed heavy iron wire. The rice is fed from above be- tween the stone and the sieve and is thor- oughly rubbed before passing out at the bottom. The severity of the scouring is regu- lated by raising or lowering the stone, thus decreasing or increasing its distance from the wire screen. The best milling practice now approves the use of the pearling cone, because with its use the grain may be more gradually scoured than where the hullers alone are used and the breakage can also be kept lower. The loosely adher- ing bran resulting from the action of the pearling cone is removed from the rice in a bran reel. This bran is generally combined with.
