Activity: Liquid Filling Line By, Tey Yi Shen

It is important to know the type of behavior of the fluid we want to dispense into its container, in order to transfer or package them in well manner.

In these video, showing that it is vital for us to know the viscosity of the liquid that we want to dispense. Hence, we can know the right time that we need to allow the opening of the pipe to flow the fluid out. By knowing the viscosity of the liquid at that specific time (dispensing), we can calculate the time and force we need to apply. This has to be regulated with other process/instrument so that the process can run smooth from the beginning to the end. For example, the dispensing time needs to be suited with the time of the bottle passing by. (the bottle will not move on half half way the fluid is dispensing from orifice)

Another point is, we have to know the yield stress of the liquid to ensure enough force is applied to pump it out and then into respective container. Otherwise, consumer will see empty bottle or not fully filled bottle (but manufacture won’t distribute this to market right…) for the liquid which exert Bingham or Plastic behavior.

In the video Filling machine for honey, we can observe that honey is non-newtonion time dependent behavior

Honey is non-newtonion fluid, so it will return to the flat shape after dispensing. Meaning, it will not show stand up characteristic.

One of the instrument involve multiple heads nozzle in the filling, this is to minimize the shear generated to the fluid. By decreasing the shear, we can minimize the disturbance which are caused by shearing. This is important especially for shear-sensitive fluid.
