Research on the effects of some structural parameters on high productivity cassava chopping machine (10 -20 ton/h) using the experimental planning model

Abstract

This article presents the research on the effects of the structural parameters on
high productivity cassava chopping machine. Experimental research results
have identified the mathematical equations indicating the influence of three
basic structural parameters on the chopping process of cassava chopping
machine (the rotation speed of the disk n, the angle of knife position β, the
angle of knife grinding σ) to productivity Q, the individual energy
consumption q and the ratio of broken θ. From the analysis of variance using
the optimal method of multi-objective function of level 2 Box Behnken
Design model, the determined optimal conditions are: the rotation speed of
the disk is 200 rpm; the angle of knife position is 100 and the angle of knife
grinding 250. Under these conditions, the highest predicted performance was
0.9162%. Correspondently, the expected value of objective function is: the
biggest productivity is 11.6734 ton/h, the smallest individual energy
consumption is 6.13554kW/h and the smallest ratio of broken is 1.50621%.
