Juice extractor and spiral-extruded juicing screw thereof

Abstract

The invention discloses a juice extractor and a spiral-extruded juicing screw thereof. An extrusion juicing part is formed at a spiral part of an outside surface of the spiral-extruded juicing screw;an upper part of the extrusion juicing part upwards extend in a spiral manner, and a holding cavity for enabling a rotary central axis of the screw to penetrate is formed between an inside surface andan inner wall of a filter module of the juice extractor; the food material with size exceeding the semi-diameter of the screw can be fed through the holding cavity, and the rotary central axis of thescrew is located in a horizontal projection plane of the holding cavity. The juice extractor is free from using a positioning shaft, a vertical size of the screw is reduced, then the volume of the juice extractor is reduced, and the material cost is reduced, so that the juice extractor is convenient to transport and store; and meanwhile, the top of the extrusion juicing part of the screw is eccentrically arranged, the rotary central axis is located at a discharge channel outlet and the horizontal projection plane of the holding cavity, the size of the holding cavity is increased so that the holding cavity can hold the food material with the size exceeding the semi-diameter of the filter module, and the juicing effect and the juicing efficiency are increased.

Description

technical field [0001] The invention relates to the technical field of juice extractors, in particular to a juice extractor and its helical extrusion juice extraction screw. Background technique [0002] Fruits and vegetables are the main foods for the human body to take in vitamins. Studies have shown that people who often eat fruits and vegetables have a higher health status than those who do not like to eat fruits and vegetables. Especially in terms of disease prevention, fruits and vegetables also play an irreplaceable role, which is really a part of a healthy diet. excellent product. Although fruits and vegetables are rich in nutrition, many people do not like to eat them directly, but use a juicer to extract fruit and vegetable juice. [0003] Existing juice extractors generally include a machine base, a juice collecting chamber connected to the machine base, a screw rod and an extruding filter cartridge arranged in the juice collecting chamber, and a loamer covering ...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the existing juice extractor uses a positioning shaft to connect the screw rod, which leads to a higher setting of the screw rod and an offset setting of the feeding channel, which increases the overall volume, and the feeding is inconvenient, resulting in a poor juice extraction effect. The problem of low juice extraction efficiency
