A food preparation appliance including a housing containing a sieve having an inner perforated surface for extracting fruits and vegetables into liquids and solid particles, a source of rotatable power for rotating the sieve, and a manually operated cleaning device for removing pulp of food particles from the perforated surface of the sieve. The cleaning device includes a cleaning implement having a first position normally biased into a non-engaged position from the perforated surface and a second position when the cleaning device is operated to an engaged position against the perforated surface. The cleaning implement is biased against the perforated surface in the second position using a biasing member configured to maintain constant engagement of the cleaning implement against the perforated surface while the sieve is rotated. In an embodiment, the biasing member is a coil wave spring.
