A juice extractor module includes a cover and a juice extractor fluted dome and pulp filter which filters the extracted juice. A second module is formed by a pitcher. The juice flows into the pitcher through the pulp filter of the first module. Apaddle depends from a third module and is driven by a motor and gears simultaneously with the extractor, for mixing the extracted juice and other ingredients such as water, sweeteners, etc. The third module contains the motor, drive gears and switch in substantial fluid isolation from the first and second compartments, for driving the paddle and the juice extractor. Different extractors may be attached for different size fruits. A lid may be attached over the pitcher for juice/beverage storage.
