A counter-rotation twin screw extruder
A counter-rotation twin screw extruder and single screw extruder and sheet production extruder for extracting a juice by squeezing vegetables and/or fruits has mutually engaging screws mounted to two mutually parallel rotary shafts which rotate in mutually opposite directions. The screws are enclosed inside a screen structure made of a curved member made of a stainless steel plate and having slits through which juice is collected.
Examples of conventional twin screw rotary extruder include co-rotation twin screw extruders having screws mounted to two shafts adapted to rotate in the same direction and compounding extruder having screws mounted to two shafts adapted to rotate in opposite directions.
