Abstract
The article presents a developed design of a sectional pneumatic screw conveyor intended for laboratory experimental studies on the transport of bulk materials used in the food industry. To determine the influence of bulk material transport parameters and conveyor design parameters on productivity (the optimization parameter Q), a full factorial experiment was conducted. Based on the experimental results, corresponding regression equations and response surfaces were developed to establish the influence of the controlled factors on productivity. Investigation of the transport process made it possible to determine the dependence of productivity on several factors characterizing the process, namely: the screw rotational speed n (rpm), the outlet opening area of the conveyor hopper S (cm2), the moisture content of the transported material W (%), and the air pressure P (MPa). Thus, productivity can be expressed as a functional relationship of the form: Q = f(n, S, W, P).
