Abstract:
A sieve device is provided. The sieve device includes a sieve body and an inlet unit. The sieve body includes a cylinder, a filter, and a blade. The cylinder is adapted to be supplied with a powder. The filter is disposed at a bottom of the cylinder. The blade is adapted to agitate the powder within the cylinder to allow the powder to pass through the filter. The blade is rotatable about a rotation axis that intersects with the filter in proximity to the filter. The inlet unit is adapted to introduce the powder into the sieve body.
