Abstract
A juice extractor including a helical spindle connected to a power driven source, and a housing having an inlet in the upper part and an outlet in the lower part. The helical spindle includes a fine grinding portion and a refine grinding portion. At the end part of the helical spindle is a drum cap which includes a durable bushing element. The drum cap has a threaded tube portion formed in the lateral direction to join with a pressure control cap which has a squeezing flange formed on the inner part of the circumference thereof so as to press a circular protrusion of the bushing element in order to control the optimum squeezing pressure and maximize the effectiveness of the compression of foodstuff such as fruit or vegetables.
Claims15
