Rapidly-and-automatically-fed extrusion type juice extractor

Abstract

The invention discloses a rapidly-and-automatically-fed extrusion type juice extractor. The juice extractor comprises an extractor base, a motor arranged in the extractor base, a driving unit arranged in the extractor base, an extrusion screw, a squeezing assembly matched with the extrusion screw to extrude materials and a feeding assembly; the squeezing assembly comprises a squeezing cavity; a feeding opening is formed in the lateral wall of the squeezing cavity; the feeding assembly comprises a feeding channel communicated with the feeding opening; the juice extractor further comprises a material pushing part for downwards guiding the materials; the material pushing part is arranged corresponding to the feeding opening of the squeezing cavity; and an included angle between a connecting line of geometric centers of two ports of the feeding channel and the vertical direction and an included angle between the connecting line and a vertical panel are alpha, wherein the alpha is larger than or equal to 0 degree and smaller than or equal to 80 degree. By means of the structure, rapid and automatic feeding can be achieved, and large-caliber feeding can be easily achieved.

Description

technical field [0001] The invention relates to a food processing machine, in particular to a household squeeze juice extractor. Background technique [0002] There are two types of existing vertical extrusion juice extractors: [0003] The first category is a juice extractor disclosed in Patent No. CN200780001269.X, which includes a cover, a shell, a screw, a mesh cylinder matched with the screw, a rotating brush and a drive unit, and one side of the cover is provided with a feed port. The juice extractor solves the problem of extracting juices of different thicknesses by using the characteristic of the liquid flowing downward. At the same time, because the machine base is set at the bottom, the stability of the machine is good. However, the feeding port of this scheme is set above the screw, and after the material enters the casing, it falls above the spiral of the screw, which is not easy to feed. At the same time, if the material falls into the position close to the axi...

AI Technical Summary

Problems solved by technology

Although this solution solves the problem of the material falling into the axis, and solves the problem of the feeding diameter to a certain extent, it needs to set a depression at the bottom of the cover body, and the shape is irregular, that is, the size of the feeding port to the bottom is determined by Large to small, its disadvantage is that it is only suitable for juicing spherical materials, such as apples, tomatoes, etc. For juicing thicker carrots, cucumbers and other strip materials, it is easy to get stuck, and it is poorly adapted to the diversity of materials. The processing is difficult, and because the feed port is still set above the screw, although the smoothness of feeding has been eased, it still cannot solve the problem of automatic feeding

[0005] Therefore, whether it is the above-mentioned first type of small-diameter vertical screw extrusion juicer, or the above-mentioned second type of vertical screw extrusion juicer that can realize large-diameter feeding, the feed port is arranged above the screw rod. Even if it is set eccentrically, due to the limited space, the material is still close to the center of the screw, and some materials are still not easy to be bitten by the screw, resulting in slow feeding and low processing efficiency; and the screw mainly relies on cutting ribs. The radial force is used to cut the material, which generates a large torque and increases the working load of the motor, which still causes the problem of easy material jamming
