The
powder must flow smoothly from a small container.
Example:
A dairy creamer must pour smoothly and
consistently from its packaging.
The dairy creamer must be added to the beverage at
a constant rate with little added effort.

The
powder must fill a processing die evenly and repeat ably.
Example:
A tableting die must be filled with the same
amount of powder every time to
insure a proper dosage of the drug.

Test Method: Flowability,
Granulation and Caking |
|
|
|
The
powder must form larger particles during
a granulation process.
Example:
The formation of large granules helps the powder
flow smoothly through process handling
equipment.

Granulation |
|
The
powder must not have large granules or clumps after transportation
or storage.
Example:
A face powder must not have large clumps in its
container. The
powder must have the same size particles so the face powder
will apply evenly to the face.

Test Method: Flowability and
Caking
|
|
|
|
The
powder must remain the same particle size during
handling, mixing
or blending.
Example:
Milk powder has to mix properly with water
for the powder to dissolve properly. Large clumps of powder that
do not dissolve can plug bottle nipples.

The
powder must fluidize.
Example:
Toner must fluidize to adhere to the printing
surface. If
the toner does not fluidize in the drum, it will cause uneven or
missing printing.

Method: Fluidization |

The
powder creates large particles or cakes during storage
and must break up during usage.
Example:
Baking products form large clumps during storage.
This caking property makes it difficult for the
consumer to remove the product from the container.

Method: Caking |
|
The
powder must not fluidize.
Example:
A percentage of the powder fluidizes during
processing. The
manufacturing facility is unable to process the material
adequately and effectively. The factory is losing a percentage of raw
material due to the fluidization process adding to the raw
material cost.

After the powder
flows from the silo, the powder must not contain clumps.
Example:
A food powder is stored in a silo. The
powder is removed from the silo for processing.
Due to storage in a silo, the powder has formed large
clumps. These large clumps cause mixing
complications in the manufacturing process.
