“…Acoustic chemometric studies related to characterization of particulate material and pneumatic transport lines have been well established in previous studies [21][22][23][24]. Previously published literature on acoustic chemometrics for particle characterization has shown that it is possible to predict particle size, moisture content, crystallization point etc.…”

“…Acoustic chemometrics is a non-invasive on-line PAT technique which has entered a new phase in recent years. The recent advances offer vast opportunities for research and development in areas of technological applications which are documented in the literature [21][22][23][24][25]. Mass flow rates of material transported in pneumatic conveying lines in dilute phase [21] and dense phase [26] systems have previously been investigated.…”

Fish farmers consider the cost of fish feed pellets as one of the most expensive factors in fish cultivation. Proper control of the handling and conveying systems is necessary to avoid damage and disintegration of the cylindrically shaped fish feed pellets. Pneumatic conveying is widely used to transport large quantities of fish feed. Proneness of crushing the fish feed pellets caused by pellets interaction with the inner wall of the pipeline is a major concern to the manufacturer due to the associated economic loss; pellet damage increases exponentially with the conveying air velocity. On the other hand, too low conveying rates would lead to pipeline blockages and severe pipe vibration. In order to address the foregoing issues, it is necessary to optimize the conveying velocity of fish feed pellets during pneumatic transport. Application of an on-line monitoring technique based on non-invasive passive acoustic measurements and multivariate regression modeling (acoustic chemometrics) was investigated. A partial least squares regression (PLS-R) model was calibrated to predict pellet velocity from 19 m/s to 36 m/s in a pilot scale pneumatic conveying system. The PLS-R prediction model was validated based on independent experimental data (test set validation). The root mean square error of prediction (RMSEP), slope and r 2 of the prediction results were 0.64 m/s, 1.02 and 0.97 respectively. The prediction results obtained shows the applicability of acoustic chemometrics for real-time prediction of the velocities of fish feed pellets during pneumatic conveying.

“…In this regard, the calculated frequency spectra are thus related to the physical/chemical properties of the investigated materials/test system. In recent years, application of acoustic chemometric for various research and industrial process studies has increased [7,[12][13][14][15][16][17]24]. The advantages of acoustic chemometrics as compared to other on-line methods are numerous and some of them can be summarised as follows:…”
