Heat treatment of crushed oil seeds sunflower before pressing

Abstract

The work investigates the process of preliminary heat treatment of oilcake of sunflower variety Dushko in the field of infrared irradiation before pressing. Based on the planning of experiments, a pattern of changes in the value of the output parameter - the residual oil content of the crushed oil seeds sunflower - was obtained from factors influencing the process: radiant flux density and duration of irradiation in intermittent mode. Using Response Surface Methodology, the optimal values of the influencing factors were determined: radiant flux density 7.2 kW/m2 and irradiation duration 160 s, at which the residual oil content of sunflower oilcake will be within 9.5-10% after the first pressing.
