CONSTRUCTION AND TECHNOLOGICAL PARAMETERS OF THE PROCESS OF REDUCING GREEN MASS OF ENERGY- AND RESOURCE-SAVING PRODUCTION OF LIVESTOCK PRODUCTS

Legumes and leguminous crops, especially alfalfa, clover, amaranth, etc., should be considered the most promising from the point of view of providing animals with feed with a high protein content. One of the possible promising ways to solve this problem is the technology of fractional processing of alfalfa and other legumes. One of the important operations in this technology is the grinding of green mass. After all, the amount of green juice obtained - the raw material for the production of PVC (protein-vitamin concentrate) - depends on the length of the cut and the degree of splitting of the plant stems. A significant role is also played by the energy consumption of the process of grinding green mass. Among serial stationary machines for grinding fodder, only a few of them can perform the task with acceptable quality, productivity and energy consumption. When designing the technological line, the IKV-5A shredder was planned for the grinding operation. Conducting the first production tests on the functioning of the equipment for grinding green mass of alfalfa on the IKV-5A feed grinder confirmed the assumption that the degree of grinding has a significant effect on the yield of green juice. Thus, when the cutting length was reduced from 50 mm to 10 mm, the juice yield during further squeezing increased from 15% to almost 22%. But during the first tests, shortcomings in the operation of the IKV-5A shredder were also discovered. This shredder turned out to be too energy-intensive and unreliable in operation. The analysis of literary sources, our own experience proves that currently in Ukraine there are practically no technical means for successfully carrying out the grinding operation for the needs of the technology of fractional harvesting of leguminous herbs. A promising way to solve the problem of the implementation of the grinding operation within the framework of the technology of fractional harvesting of legumes is the development of our own machines that meet the set requirements, in particular, disintegrators with a vibration effect on the material during the grinding operation.
