STREAM OF EFFICIENCY OF RICE GRAINS MULTI-DISC GRINDING

A search for design solutions for grain grinding devices offering energy-saving production processes justify the research into the improvement of the theory and the design of grinders. The efficiency, functionality and performance of the rice grains grinding are significantly influenced by processes, difficult to describe, occurring within the working space of the grinder. Although there are some studies on the principles of the functionality and analysis of multi-disc grinders, an attempt has not been made so far at describing the influence of features and behaviour of ground material on efficiency, performance and usefulness of the biomaterial comminution/grinding process. The basis for the improvement of the functionality of a grinding device is an analysis of the potential of existing solutions and a determination of the scope of effective design features of the working unit within the permissible area. The criteria may be fulfilled by objective-oriented control of the design features of the multi-disc unit. In order for these actions to be effective, relevant relationships need to be explored and a mathematical description needs to be developed for the flow of ground grains through the working space of a multi-disc grinder, as a result variable of the structure and the operation of a working unit.
