The shake grader is designed to grade produce according to the square size with four-dimensional grading. The produce is fed to the top of the machine onto the top sieve. The sieves in the machine shake in sequential frequencies, which causes the produce to move along on the sieves. The movements of the sieves are caused by the motor on the front side of the machine. This motor drives a crankshaft. The crankshaft causes the shaking of the sieves. The motor of the machine has a computer controlled frequency inverter, which causes the sieves to shake in several sequential frequencies.
