| In this work, the effects of raw material and process parameters on product expansion in a fish feed extrusion process were investigated. Four different recipes were studied with a pilot-scale twin-screw co-rotating extruder according to a set of pre-defined processing conditions. In the four recipes, wheat and protein contents were adjusted and compared with a reference sample. It has been found that a dimensionless equation can well correlate the process parameters and product bulk density for the four different recipe extrusion. The average deviation of the correlation for bulk density is 2.4%. The experimental data show that product expansion decreases with increase of protein content. Several different methods have been applied to quantitatively... |
