Je. Schlesser et al., VOLUMETRIC FLOW-RATE COMPARISONS FOR WATER AND PRODUCT ON PASTEURIZATION SYSTEMS, Journal of dairy science, 77(4), 1994, pp. 950-957
A flow calibration tube system was assembled to determine the volumetr
ic flow rates for water and various dairy products through a holding t
ube, using three different flow promotion methods. With the homogenize
r, the volumetric flow rates of water and reconstituted skim milk were
within 1.5% of each other. With the positive displacement pump, the f
low rate for reconstituted skim milk increased compared with that for
water as the pressure increased or temperature decreased. The largest
increase in flow rate was at 310-kPa gauge and 20-degrees-C. On a magn
etic flow meter system, the volumetric flow rates of water and reconst
ituted skim milk were within .5% of the flow rate measured from the vo
lume collected in a calibrated tank. The flow rate of whole milk was s
imilar to that of skim milk on the three flow promoters evaluated. Ice
milk mix increased the flow rate of the positive displacement pump, b
ut not the homogenizer and magnetic flow meter system.
