A neural network was designed to predict the rheological properties of
dough from the torque developed during mixing. Dough rheological prop
erties were determined using traditional equipment such as farinograph
and extensigraph. The back-propagation neural network was designed an
d trained with the acquired mixer torque curve (input) and the measure
d rheological properties (output). The trained neural network accurate
ly predicted the rheological properties (>94%) based on the mixer torq
ue curve. The ability to measure the rheology of every batch of dough
enables online process control by modifying subsequent process conditi
ons. This development has significant potential to improve product qua
lity and reduce cost by minimizing process variability during dough mi
xing.
