Abstract: The present invention comprises a system for cracking grain preferably comprising four cracking cylinders, wherein the cylinders are preferably individually and independently driven by a separate motor, with motoreducers and frequency inverters, and controlled by a speed divider, which is capable of independently adjusting the speed of each cylinder. The position of the cylinders is preferably adjustable to adjust the spacing between opposing cylinders. Humidity sensors can be provided to determine the moisture content of the grain being processed. These adjustments are preferably automatically controlled by a programmable logic control, installed on an electric control panel.
