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 mesh size, a perimeter and a gasket positioned adjacent the perimeter,
- wherein 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 method of transferring a particulate material from a first container to a second container using a system comprising an upper portion, a lower portion and a sieve, the 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, the lower portion comprising a collector funnel, a low frequency vibrator and a collar securing the low frequency vibrator to the collector funnel, and the sieve comprising a mesh size, a perimeter and a gasket positioned adjacent the perimeter, wherein 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, the method comprising:
- a) moving the particulate material to the upper portion from the first container;
- b) vibrating the upper portion with the high frequency vibrator and the lower portion with the low frequency vibrator;
- c) passing the particulate material through the sieve to the lower portion;
- and,
- d) moving the particulate material from the lower portion to the second container.
