| Abstract | The continuous recording tube flow viscometer developed in the AFE division, AIT was slightly modified to obtain flow behavior data for banana puree at low shear rates, even the of the working shear rate range of the LV Brookfield rotational viscometer, 4 to 100 1/s. The performance aspects of the assembly was investigated using sugar solution, a Newtonian fluid. It was found out that its performance is optimized by gathering data over a wide shear rate range; a comprehensive picture of the flow diagram of the sample is obtained. Banana puree of 35% total solids was prepared and characterized using both the tube flow viscometer assemble and a Brookfield rotational viscometer. K and n' parameters from both as well as literature values available were found to be comparable. The sample was pseudoplasticity in behavior. Investigation and correction of slip and end effect efforts on the flow behavior of banana puree were also conducted. It was verified that at low shear rates, in the absence of slip and end effects, the flow behavior of banana puree becomes independent of tube radius. |
