Illia LYTVYNOV – Postgraduate Student, Technician of the Department of Technical Systems Engineering of Dnipro State Agrarian and Economic University (St. S. Efremova, 25, Dnipro, Ukraine, 49000, e-mail: illalitvinov901@gmail.com, https://orcid.org/0009-0001-7961-8086).
The study addresses the technical challenge of improving the efficiency of the fractionation process of crushed cake from niche oil crop seeds by enhancing the design and parameters of a rotary brush separator. It has been established that traditional devices exert low intensity on the bulk material and do not ensure adequate quality of fraction separation and sieve cleaning. An experimental test rig was developed to investigate the influence of design and technological parameters such as rotor rotational speed, feed rate, brush orientation angle, and brush assembly offset angle on the separator’s performance indicators.
The aim of the research is to substantiate and determine the optimal design and technological parameters of the brush rotary separator for effective cleaning of crushed castor cake by means of multi-criteria optimization of machine performance indicators, namely the degree of sieving, the undersieve coefficient, and specific electricity consumption.
As a result of the experimental studies, a test rig for experimental investigation of the rotary brush separator for crushed cake of niche oil crops was created, and dependencies were obtained for the degree of sieving k (%), the undersieve coefficient η (%), the power consumed by the separator P (W), and the specific energy consumption E (MJ/kg) as functions of the crushed cake feed rate q, brush shaft rotational speed n, brush orientation angle α, and brush assembly offset angle β.
Following multi-criteria optimization performed using Wolfram Cloud and the method of multiplicative objective function minimization, the rational values of factors were determined: crushed cake feed rate q=577.2 kg/h, brush shaft rotational speed n=86.4 rpm, brush orientation angle α=14.8, and brush assembly offset angle β=49.9. Under these conditions, a high degree of sieving k=33.4% is achieved with a low undersieve coefficient η=3.6%, minimal specific electricity consumption E=0.00566 MJ/kg, and moderate power consumption P=886 W.
The obtained results confirm the feasibility of applying this method for optimizing the operation of machines of this type and demonstrate the effectiveness of coordinating design and operating parameters considering a set of quality criteria.
