Description

Technical Field

[0001] The utility model relates to the technical field of juicing, and particularly relates to a food chopping, grinding and juicing machine. Background Art

[0002] With the increasing improvement of people's living standards and the demand for homemade processing of green food and beverages at home, various juicers have emerged. There are mainly two juicing methods for existing juicers. The first is high-speed cutting and centrifugal drying juicing, and the second is slow-speed strong extrusion juicing. Although the first juicing method has the ability to juice quickly, due to the large volume of the centrifugal bowl in the juicer, the noise and vibration during the high-speed operation of the juicer are relatively large, causing great noise pollution to the operating environment. Although the second juicing method solves the noise problem, the juicing speed is relatively slow, the operation time is too long, and the fruit must be cut open in advance before use, and the operation is relatively complicated.

[0003] In the prior art, a pre-cutting cutter head and pre-cutting blades are used for cutting, and the structure is complex. Since the pre-cutting blades are of a generally planar structure, the chopping efficiency is low; moreover, the structures of the pre-cutting cutter head and the pre-cutting blades are mainly applicable to the pressing of thick and long fibers such as sugarcane. When other foods are placed in the juicing cup, it is easy to cause the food to get stuck between the pre-cutting cutter head and the pre-cutting blades, affecting the operation of the slow juicer.
