Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a fruit and vegetable juice extraction device. Background Art

[0002] Among the existing fruit and vegetable juice extraction equipment, the traditional juicer undoubtedly occupies a core position. The working principle of this type of juicer is relatively simple and intuitive. Users only need to put the cut fruits and vegetables into the top feeding port of the device. Inside the device, the most core component is one or more carefully designed screws. These screws are engraved with special threads, and the width of these threads gradually decreases from one end of the screw to the other, forming a clever gradient.

[0003] When the juicer is started, the screw begins to rotate slowly. During the rotation, the fruits and vegetables are guided by these gradually narrowing threads and gradually move toward the outlet end of the screw. At the same time, due to the squeezing effect of the threads, the juice in the fruits and vegetables is gradually squeezed out and flows into the collection container along a specific channel. However, although this design achieves juice extraction to a certain extent, we must also note that the squeezing force of the screw has certain limitations. This limitation results in some juice in the fruits and vegetables cannot be completely extracted, thus affecting the overall juice extraction efficiency. Utility Model Content
