AP22685422 «Improving the press to improve the efficiency of safflower oil production»

A mathematical modeling system and an engineering calculation methodology have been developed to improve the pressing process using a pressure control mechanism. The consistency between the mathematical modeling results and experimental studies was validated through advanced engineering calculations for the efficient extraction of oil from safflower seeds, accounting for interrelated factors (pressing temperature, speed, and pressure; oil separation time; equipment design features; energy consumption; and productivity).Based on the relationship between speeds within a specific range and the diaphragmatic gap, harmonic parameters satisfying the process requirements were identified: a speed of ω=6,2 rad/s and a clearance between the screw and the cage bars of δ=5·10^-3 m. Through the dashed line indicating the inclined intersections, the productivity and pressure during efficient oil separation were determined. The deviation between the experimental results and the mathematical modeling analysis system does not exceed 4.6%. These research findings are detailed in the article titled "Development of a Mathematical Model for the Vegetable Oil Pressing Process," which has been accepted for publication in the scientific journal Science and Technology of Kazakhstan (Toraighyrov University).The dependence of the product's structural and mechanical properties (yield shear stress, plastic viscosity, and effective viscosity) on the pressing temperature and residual oil content was experimentally investigated. The "Structurometer ST-2" instrument, designed for solid and plastic materials, was used to determine the structural and mechanical properties of the safflower product. For analyzing the yield shear stress of the press cake, a "Cone" indenter with a 45° apex angle was utilized.

Based on the research results, an article titled "Development of a Mathematical Model for the Vegetable Oil Pressing Process" has been published (Scientific Journal of Toraighyrov University, Science and Technology of Kazakhstan).
