| Abstract | Introduction. Studies of the grinding modes in the shredded process have established that there are modes of grinding grain and similar product of the shredded process in roller machines which achieve the highest yield of grain products, which are then sent for enrichment. The highest yield of grain products that can be obtained in the shredding process makes it possible to increase the yield of high-grade flour, which is obtained on the first three grinding systems. There are no data in the literature and information sources on the modes of grinding of roller machines of the most important first three grinding systems of the first quality on which the largest amount of high-grade flour is obtained. These issues are important for designers when developing the grinding balances of new flour mills, as well as for flour mill technologists. Based on this, one of the tasks of our research is to study the modes of grinding of grain products in roller machines and entoleiters-dismembers, as well as their combined action. Aim. Increasing the competitiveness of products of domestic flour mills by improving the technological process of grinding wheat grain into flour and reducing energy consumption in the process of its production. Methods. Studies of wheat grain quality and grinding products were carried out in the production laboratory in the production conditions of the flour mill with a capacity of 330 t/day. To study the system "roller machine - entoleiter-dismembler" the first three grinding systems of the first quality were chosen, on which entoleiters-dismembers are installed for maximum grinding of enriched products into flour. Results. The modes of grinding are determined and the mathematical dependences of the product of flour and grain products of the first grinding system with additional equipment entoleiter-dismembler ESM-1,5 are offered. The largest product of flour on the 2nd grinding system is achieved by grinding modes on a roller machine – 35 %. The use of entoleiter-dismembler ECM-1.5 allows to increase the total product of flour on the 2nd grinding system to 62 %. Conclusions. The modes of grinding of intermediate products of first-grade grinding in the rollers and ESM-1,5 dismembler enthlators are investigated. On the basis of experimental data, the dependences of the output of certain classes of intermediate products of grinding from the products of the studied systems are obtained. | ||
