Abstract

Regarding the importance of sizing and GRADING crops for marketing and as well as processing operations, a machine was designed, constructed, and evaluated for HAZELNUT sizing. The machine design was based on sizing mechanism of DIVERGED BELT type. The sizing unit benefits from a structure similar to a horizontal belt conveyor, where instead of the belt; a continuous endless rope is divertingly wrapped around the driven and driving roller grooves. The distance between the ropes at the entrance of the input product (the end of the driven roller) is small becoming gradually larger to the other end of the drive roller. HAZELNUTs are continuously fed into the sizing unit through the feeding unit that consists of a hopper and an inclined conveyor. HAZELNUTs along the sizing path based on the size discharged on the tray with the output being led to the drain. In this plan, HAZELNUT is sized as based on the smallest diameter in the three sizes as small (less than 14 mm), medium (greater than 14 mm and less than 16 mm) and large (greater than 16 mm). The evaluation results indicated that the linear velocity and the class size significantly affected on the performance of the machine. The most appropriate linear rope speed was determined as 0.8 m/sec. Sizing machine efficiency for medium-sized nuts is highest and at about 92%. The overall efficiency of 84% was estimated for the machine.
