RESEARCH OF EFFICIENCY OF PROCESS OF PREPARATION OF MIXTURES IN THE MIXING MACHINE WITH THE CONTINUOUS INTRODUCTION OF COMPONENTS
Introduction. The article deals with the problem of increasing the efficiency of mechanization for preparation of feed in livestock. At the present stage of development of the agricultural sector, in a market economy is not growing involves additional investment per unit area and the animal's head, and there is a necessity in the development and creation of new advanced technologies to ensure a continuous production process at the lowest cost. Materials and methods. The review of the equipment for the preparation of feed mixtures for different industries, as well as their classification. Results. According to the analysis of structures of mixers and installations proposed experimental design, which allows covering the whole range of devices supplied, but additionally replacing the auxiliary equipment required for the stable course of the process. The design combines the functions of the pump, mixer and metering device, which in turn reduces power consumption. Discussion. It is shown the method of evaluating the quality of the mixture (degree of uniformity) with continuous introduction of components, as well as a diagram of the laboratory setup. Experimental studies have shown a range of supply installations for different speeds of the impeller shaft. Mixing Studies have confirmed the effectiveness of the design and installation of its components devices: power supply, pump and mixer. With the help of experimental design methods identified the main factors influencing the mixing process, and the optimal blend of quality parameters. Conclusion. When the installation of a pump, got the feed range when opening and closing the loading chamber and the mixing quality metrics while continuously introducing components, and water temperature t = 25... 38 o C and the rate of rotation n = 1 500... 1 600 min-1 reached the value of the degree Θ = 94,8 %.
