Grinding of biological materials is an energy-consuming process. During grain decohesion, complex strain state occurs induced by compressing, twisting, bending, tearing, cracking, grinding or shearing. The work attempts to find structural solutions of the grinding and process control system enabling to increase rice grinding functionality: efficiency, energy-saving and regularity. The practical aim was to develop the methodology for innovative research on grain grinding which supports development of grinders. Based on theoretical discussions and earlier scientific research, it can be concluded that it is possible to obtain optimal quality of material being ground and satisfactory functionality of the rice grain grinding process within a permissible range of values of the multi-disc grinder structural features. The exceeding of these values will result in the worsening of the process effectiveness and the quality of a grinding product. Finding relations between functionality, operation regularity, selected movement and energy related characteristics of the grinding process and structural features of the biomaterial grinding unit justifies the need for carrying out an analysis, studies and experiments with quasi-shearing in order to determine the indexes of the research object model variables.
