Abstract

This study investigates the dynamic behaviour of particle velocity in a pneumatic conveying system for bird food, focusing on the effects of blower voltage and feed rate on system performance and stability. Particle velocities were recorded under blower input voltages ranging from 4.5 to 7 V (2310 to 3260 rpm) and feed rates from 30% to 70%, using a rotary feeder. Principal Component Analysis (PCA) revealed that the first two components accounted for most of the variance in particle velocity, indicating a significant but not exclusive impact of the studied variables. Autocorrelation analysis of detrended particle velocity showed substantial system inertia, with a decay rate of -0.046 over five 1-second intervals, highlighting the influence of historical conditions on current dynamics. This insight is crucial for refining control algorithms to manage temporal dependencies within the system. Cross-correlation analysis identified a time-lagged response in particle velocity following adjustments in blower voltage
