With a method as well as a system for processing of sunflower extraction grist, particularly for obtaining proteins, wherein the particles from shell kernel parts and adhering proteins of the extraction grist are separated from one another by means of screening, a solution is to be created for processing the extraction grist of sunflowers, which occurs in the production of sunflower oil, in such a manner that it can be utilized in many different ways and, in particular, in practical manner.This is achieved, in terms of method, by means of the following steps:comminuting the grist by means of breaking it in beater impact mills (3) and/or corrugated rollers (16), screening the mixture of coarse and fine particles produced, separating the plant shells (fibers) and proteins by using water (5, 18), drying (6) the components, and pressing (8) the woody components into pellets as fuel for energy production.
