Fruits or vegetables are insert into a chamber and contacts a auger screw (worm) that breaks down the plant material and then presses it against the housing, straining screen or crushes it. The slowly rotating mechanism creates great pressing force on the fruit and vegetable matter and forces the juice out of this plant matter leaving a very dry pulp material that is automatically eject. This slow rotating mastication process minimizes heat and oxidation of the juice to preserve nutrient value. This method tends to provide a more pulpy and fibrous juice. Use requires reasonable force to insert hard fruits and vegetables into the feed chute and press against the auger or screw mechanism. Large fruits and vegetables must be cutting up into smaller chunks. Attachments make machines more versatile in preparing nut butters, pureed foods and pastas.
