AI Technical Summary

Technical Problem

Conventional juice extractors require pre-cutting of materials before juicing, leading to potential nutrient loss and difficulty in processing certain fruits and vegetables, and existing solutions increase juicer size and complexity.

Method used

A screw design with spiral ribs that extend radially outward and upward, featuring a crushing section with an inclined surface for guiding and cutting the material, a containment space for crushing, and a transfer surface for smooth material transport, reducing the need for pre-cutting and minimizing juicer size.

Benefits of technology

Enables smooth introduction and transfer of materials without pre-cutting, reduces load on the screw, and maintains nutrient integrity while efficiently processing various fruits and vegetables.

Abstract

To provide a screw for a juicer, which can smoothly input and transfer an object to be juiced without the need to cut the object before input, and a juicer equipped with the screw. [Solution] In a screw for a juice extractor that rotates around a screw rotation axis and has spiral ribs formed on its outer circumferential surface, the screw is provided with a crushing section that extends radially outward and upward from the screw rotation axis and cuts the material to be juiced. The crushing section is formed to protrude above the upper end of the screw rotation axis and includes an inclined surface that guides the material to be juiced when it is fed, and a cutting section that forms an inclination angle with respect to the screw rotation axis and cuts the material to be juiced.
