An automated rapid non-destructive testing grader based on machine vision technology for jujubes was designed, which can discriminate and grade jujubes according to their external indicators. The equipment is mainly composed of five parts：monomeric orientation arrangement conveying system, multi-surface image acquisition and processing system, grading actuators, transmission mechanism and control system. Rapid monomeric arrangement delivery of jujubes was achieved by roller conveyor and cam intermittent motion mechanism, multi surface images of jujubes were obtained by industrial camera, front and back light and STM32 system. In addition, pneumatic grading actuator was designed to grade jujubes. The performance parameters were determined by calculating and testing，which were conveyor angle 28°, running speed 160mm/s, monomer orientation arrangement rate 95%, grading speed 10 jujubes/s,accuracy 92%, the maximum production capacity 550kg/h. The requirement of automated rapid detection and grading can be reached well by the grader.
