PRODUCTION PROSPECTS FOR PROTEIN FEEDS MADE FROM SUNFLOWER SEEDS IN SMALL FARMING ENTERPRISES
05.20.00 Processes and machines of agroengineering systems
DescriptionThe quality of feed is one of the main factors determining the development of industries necessary for the country. In this regard, extrusion technologies for processing raw materials of plant origin are of great interest. The prospect of processing plant raw materials using thermoplastic extrusion is due to two main reasons: first, the large volume and variety of products produced using this technology, and, secondly, the economic effect that gives the production of extrusion products by expanding the consumer properties of the feed produced. Extrusion equipment not only expands the range of feed, but also increases the employment of the rural population during the off-season. Therefore, the purpose of the study is to assess the prospects for the introduction of protein feed production by extruders from sunflower seeds in small agricultural enterprises. The study used an analytical review and analysis of published and patent information on technical means – extruders used for the production of protein feed from oilseeds, such as sunflower. The analysis of literature sources on the work of the existing forage preparation equipment showed that serial machines are metal-consuming, energy-consuming, used with low efficiency, due to technical and technological shortcomings. The analytical review of patent sources of extruders for preparation of compound feeds for the purpose of identification of the direction of their development and elimination of shortcomings of the existing is given. Modernization of extruders for the preparation of feed in the patent information goes in different ways, depending on the goal, which will improve their productivity and quality of protein feed. Serial production of technical equipment for the preparation of protein feed allows you to compete with foreign technology. Therefore, the development and improvement of serial domestic equipment for the preparation of protein feed from sunflower seeds for functional purposes are competitive and significantly cheaper and can reduce energy costs for their extrusion, which is an urgent task

OPTIMIZATION OF THE PROCESS OF MIXING FEED
05.20.00 Processes and machines of agroengineering systems
DescriptionBased on the analysis of the designs of feed mixers for farm animals, the option of using a two-stage mixer is being investigated. The proposed design of the mixer allows you to improve the quality of the feed mixture and reduce energy costs per process. To optimize the mixing workflow, the design parameters of the machine and their influence on the technological process under various working conditions are determined. It has been established that the design of the mixer and the initial physical and mechanical properties of the components of the feed mixture directly affect the most important technological characteristic of the installation, its performance. Therefore, the study aims to optimize the process of mixing feed
