One of the upper filtering screw squeezing juicer

Abstract

The invention provides an upper filter vertical screw squeeze juice extractor, which comprises a machine base, a juice collection chamber connected with the machine base, a screw longitudinally arranged in the juice collection chamber, and an upper cover closed on the upper port of the juice collection chamber. Cover, the screw includes a screw body and a screw shaft, and the screw body is provided with a screw, wherein, the screw body includes a feeding section, a grinding section and a slag discharge section from top to bottom, and the lower part of the juice collection chamber is provided with an extrusion crushing section, The extrusion crushing part cooperates with the screw grinding section to form an extrusion crushing gap. The upper part of the juice collection chamber is provided with a juice outlet, and the screw grinding section is provided with a helical mutation section with a larger helix angle. The upper part of the juice collection chamber cooperates with the screw feeding section. A pressure discharge channel is formed, the squeeze crushing gap is not greater than the gap value of the pressure juice discharge channel, the squeeze crushing part cooperates with the screw grinding section to make the slag fill the squeeze crushing gap under the pressure of the screw, and the juice is forced to It surges up to the pressure juice discharge channel and discharges from the juice outlet, which improves the juice discharge efficiency and optimizes the taste of the juice.

Description

technical field [0001] The invention belongs to the field of food processing machines, in particular to a vertical screw extrusion juicer. Background technique [0002] Existing vertical juice extractors generally include a base, a juice collecting cavity arranged on the base, a screw longitudinally arranged in the juice collecting cavity, and an extrusion cylinder sleeved on the outside of the screw, and a filter screen is arranged on the extrusion cylinder The upper cover with the feeding port is set above the juice collecting chamber. The user inputs the material from the feeding port, and squeezes and pulverizes in the squeezing and pulverizing gap formed between the extrusion barrel and the screw, and the juice in the material is squeezed out. And enter the juice collecting chamber through the filter mesh hole, and the juice outlet is set at the lower part of the side wall of the juice collecting chamber to introduce the juice into the juice receiving container, and the...

AI Technical Summary

Problems solved by technology

During the juicing process of the existing vertical juicer, the precision of the extrusion and crushing gap is low, and the filter mesh on the extrusion cylinder is easily blocked by fine slag, and the juice cannot be filtered out in time, so a large amount of it accumulates in the extrusion and crushing process. In the gap, the juice extraction efficiency and filtration effect are affected, thereby reducing the juice yield, and the metal filter of the extrusion cylinder is often easy to react with the juice, which affects the quality of the juice and the service life of the accessories

[0003] In addition, the juice filtered from the filter mesh needs to go through a certain distance in the vertical direction and the circumference of the juice collection chamber to reach the juice outlet, and a large amount of juice cannot be discharged from the juice outlet at the lower part of the juice collection chamber in time, resulting in juice It stays in the space between the juice collection chamber and the extrusion cylinder, and the retained juice contacts with the air, which accelerates the oxidation of the juice and affects the taste of the juice

Moreover, the extrusion cylinder is set outside the screw, and at the same time, there is a space for juice circulation between the extrusion cylinder and the juice collection chamber, so that the volume of the juice collection chamber is too large, and the whole machine takes up a lot of space, which is not conducive to storage

Moreover, the juice extractor involves squeezing and crushing many accessories, so it is not easy to install

After the juice is squeezed, the filter mesh on the squeeze cylinder is clogged and difficult to clean

In addition, the joint between the lower end of the extrusion cylinder and the juice collection chamber is prone to residual materials, which will further affect the juice yield and lead to waste of materials
