A DEVICE FOR SEPARATION OF BREWER''S DRAFF IN A LIQUID AND THICK FRACTION
One of the important tasks of animal husbandry, aimed at increasing the productivity of animals and poultry, largely depends on the use of new feed materials and the rational use of technical means and technologies in their quality preparation. In solving this problem, it is effective to use highly concentrated feed (brewers' draff) as a feed additive in the diet of animals. However, the solution to the problem of waste management of Breweries is constrained both by insufficient financial resources of agricultural organizations, and the lack of resource-saving technologies using high-performance technical means, in particular when centrifuging the beer pellet to produce a liquid and thick fraction, for which, accordingly, separate technologies for further processing are provided. From the thick fraction with the lowest possible costs by drying or pressing, the production of dry concentrated fodder to be stored for a long time. The aim of the study is to increase the efficiency of the process of separating the beer pellet into thick and liquid fractions by improving the design and mode parameters of the vibration-centrifugal continuous operation. In the article, as a result of the analysis of centrifugation devices, the design of a vibration-centrifugal unit for the separation of a beer pellet into a liquid and a thick fraction is proposed. The results of theoretical and experimental studies are presented. The equation for determination of the main design-mode parameters of the rotor of the blade vibration-centrifugal installation is obtained analytically and the differential equations describing the real process of movement of the beer pellet on the disk and rotor blades are made. The rational constructive parameters of rotor of the centrifugal device are determined. A mathematical model of the relationship between the moisture content of the beer pellet sludge and the main parameters of the vibration-centrifugal unit, which allows to determine its rational parameters, is obtained.
