Zeytin küspesi için ayarlanabilir titreşimli sıcak hava kurutucusunda kalış süresi kontrolü ve nem kaybının tekrarlanan faktöriyel incelemesi

Özet (abstract)

Abstract This study examines whether adjustable shelves and outlet shutters control solids transport in a prototype vibratory hot-air dryer for olive pomace. A replicated $$2^{4}$$ design combined two levels of each shelf inclination and shutter opening: 16 settings with four runs each. Residence time and recovered mass were recorded at 65 $$^{\circ }$$ C and 1190 rpm; velocity was derived from the fixed path. Raising shelf 2 shortened residence time by 416.4 s (95% CI: $$-419.2$$ to $$-413.6$$ s), the largest transport effect. Shutter 2 gave the largest recovered-mass effect ( $$-0.0848$$ kg; 95% CI: $$-0.0892$$ to $$-0.0803$$ kg). Factorial regression predicted held-out residence time better than a compact ANN, whereas the ANN gave the lower recovered-mass error. With inlet moisture recorded at 55%, moisture loss and outlet moisture (34.8–53.3% wet basis) were obtained gravimetrically from the combined product and cyclone-fines mass. The novelty lies in the replicated separation of four geometric adjustments and their condition-grouped predictive comparison.
