The SDA Grain Classifier has been specially designed to separate grains according to shape and size. It precisely classifies a wide variety of grains, including different types of the same seed.
The rotating discs are partially immersed in the bulk of grains to be classified, and, by rotating, they load them in cells. After that, the seeds fall in small channels where they can be checked for quality and extracted or returned to the process by just moving a valve.
The grains continue on their way to larger cells by a screw attached to the blades of the discs. At the end of the process, only the biggest seeds remain, and they can be extracted from the system through a gate that has a valve to regulate the level inside the machine.
This system can be customized and configured according to the capacity and the amount of grains to be separated.
