The study of soybean chaff pressing process depending on its fractional composition and humidity

A by-product of soybean production, as a non-grain part of the crop, can be used to meet the needs of livestock in providing complete feeding of livestock. Pressing the floor allows to reduce the volume of plant material in order to reduce the cost of storage and transportation, improve the safety of its nutrients during long-term storage. Therefore, the development of an efficient, cost-effective and less energy-intensive technology and a process line for compacting the soybean floor by pressing is a promising direction. The pile of the floor is a complex mixture of particles of different sizes, as well as voids filled with air. Equipment compaction chaff should provide a stable preparation of pellets under all the fluctuations of the moisture content and fractional composition of chaff. In 2018, research experiments were carried out in the Far Eastern Scientific-Research Institute of Mechanization and Electrification of Agriculture to study the process of pressing the soybean floor, depending on its fractional composition and humidity, on the manufactured laboratory unit for compaction with the production of soybean floor briquettes...
