Abstract
A system for transferring a particulate material from a first container to a second container including an upper portion, a lower portion and a sieve. The upper portion having a housing and a high frequency vibrator, the housing having a first end, a second end opposite the first end, and a gasket positioned adjacent the first end. The lower portion having a collector funnel, a low frequency vibrator and a collar securing the low frequency vibrator to the collector funnel. The sieve having a mesh size, a perimeter and a gasket positioned adjacent the perimeter. The upper portion is releasably secured to the first container and the sieve is releasably secured between the second end of the upper portion and the lower portion.

A system for transferring a particulate material from a first container to a second container comprising:
- an upper portion comprising a housing and a high frequency vibrator, the housing comprising a first end, a second end opposite the first end, and a gasket positioned adjacent the first end;
- a lower portion comprising a collector funnel, a low frequency vibrator and a collar securing the low frequency vibrator to the collector funnel;
- and,
- a sieve comprising a perimeter and a gasket positioned adjacent the perimeter,
- wherein the upper portion is adapted to be releasably secured to the first container and the sieve is releasably secured between the second end of the upper portion and the lower portion.
A system for transferring a particulate material from a first container to a second container comprising:
- an upper portion comprising a housing and a high frequency vibrator attached to the housing, the housing comprising a first end, a second end opposite the first end, and a gasket positioned adjacent the first end;
- a lower portion comprising a collector funnel, a low frequency vibrator and a collar securing the low frequency vibrator to the collector funnel;
- and,
- a sieve comprising a perimeter and a gasket positioned adjacent the perimeter,
- wherein the upper portion is adapted to be releasably secured to the first container, the sieve is releasably secured between the second end of the upper portion and the lower portion, the high frequency vibrator imparts high frequency vibrations to the housing, and the low frequency vibrator imparts low frequency vibrations to the collector funnel.
