THE RESULTS OF EXPERIMENTAL STUDIES OF A VIBRATING-CENTRIFUGAL DEVICE FOR THE SEPARATION OF BREWER'S GRAINS
This article touches upon the problem of utilization of beer grains forthe purpose of obtaining highly concentrated feed for farm animals, which is anactual problem for today. Based on the analysis of designs of centrifuges,developed a vibration-centrifugal unit for the separation of brewer's grains ona liquid and thick fraction. Improving the efficiency of the process andlifetime of the device is achieved through the use of differentiation(distribution) of the fluid stream in the separation process of brewer's grainson liquid and dense fraction and on that basis still thickened layer offiltered material on the surface of the blades of the rotor rotating with axialvibration, as well as reverse movement of the rotor will improve the filtrationefficiency. Conducted preliminary research to identify the zero (baseline)values of kinematic parameters: frequency of rotation of the rotor ,the amplitude of oscillation of the rotor ,the oscillation frequency of the rotor affecting the final sludge moisture content.The assessment of the impact of each factor on the sludge dewatering incentrifugal rotor vibration and centrifugal installation planned four factorexperiment at 3 levels of variation. The resulting nonlinear equation ofmultiple regression of the second order, which is a mathematical model based onthe sediment's moisture spent grains from the main parameters ofvibration-centrifugal setting specifying management settings: rotationfrequency of the rotor = 500 rpm; amplitude of vibration of the rotor = 4 mm; the oscillation frequency of the rotor = 600 rpm; the area of the discharging flow = 0,00072 m2, in which the sludgemoisture content of brewer's grains is 56 – 58%.
