Preferably the impeller comprises a hollow central core, and a shaft extends through the hollow core into at least one through-hole formed in the neck. A handle is present for turning the shaft to rotate the impeller. A base is provided with a retaining arm for removably receiving the receptacle. The system is capable of easy disassembly for cleaning, by removal of the receptacle and impeller from within the receptacle.
