A model of the fibre flows through a milling train has been developed. The model
includes the t10w of fibre suspended in juice streams that is recirculated along the
milling train as part of the imbibition system. By including the recirculated fibre, the
model is capable of estimating the fibre rate being processed by each milling unit. Using
typical tlbre contents for all fibre streams, the second mill is identified as the milling
unit that processes the greatest tlbre rate. This mill processes the fibre in the expressed
juice from the first three mills. While it is not necessary to know the amount of fibre
recirculation for most milling train calculations, it is necessary to account for fibre
recirculation when comparing factory results to outputs from fundamental milling
models. Consequently, this model is likely to be of benefit to ongoing research to better
understand the milling process.
