ABSTRACT:
A juice extractor includes first and second opposing cups relatively movable to compress a fruit therebetween, a strainer tube associated with the first cup, and an orifice tube being movable within the strainer tube and having a pressure-applying end surface for urging juice through the strainer tube. The pressure-applying end surface may have a first surface portion with an angle greater than about 130°, and more preferably about 145° to 160°, such as about 150°, for example. The orifice tube may carry a restrictor tube within an internal bore of the orifice tube in some embodiments. The restrictor tube may have a pressure-applying end surface with a similar angle.
