Description

Technical Field

[0001] The utility model relates to a juice extraction device, belonging to the field of juice extraction. Background Technique

[0002] Juice extraction is a technology for extracting nutritional and medicinal components through the dissolution and separation of substances. Its basic principle is to rely on the interaction between the solvent and the substances in the sample to achieve the separation and extraction of substances.

[0003] With the improvement of people's living standards and health awareness, how to improve food quality, reduce the residue of harmful substances in food, and ensure the quality and safety of food are important tasks in the current food production and processing industries. In order to ensure that the food put on the market meets the national safety standards, it is necessary to conduct food testing on food before it leaves the warehouse. During the food testing process, taking the juice of the sample for testing is a relatively common and important testing method. This method can clearly detect the harmful substances in the food by extracting the juice of the food.

[0004] In the existing patent document with the authorization announcement number CN217331801U, when preprocessing fruits and vegetables, the fruits and vegetables are put into the interior of the bin body, and the driving mechanism drives two crushing rollers to crush the fruits and vegetables. The crushed fruits and vegetables fall into the interior of the filter cylinder through the connecting hopper. The juice penetrates from the filter cylinder into the interior of the stirring bin. The connecting belt drives the extrusion screw to rotate inside the filter cylinder, extruding the filter residue of the fruits and vegetables from left to right and discharging it from the slag discharge pipe. At the same time, the connecting belt drives the stirring mechanism through the connecting rod to uniformly mix the juice and the reagent, avoiding the step of collecting the juice first and then mixing it, reducing the risk of juice contamination, and improving the detection efficiency. However, when using the extrusion screw to discharge the filter residue of the fruits and vegetables, some filter residues will remain on the surface of the extrusion screw, which is inconvenient to clean and will increase the difficulty of subsequent cleaning. Therefore, we provide a juice extraction device to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a juice extraction device to solve the problems raised in the above background technology. The utility model can pre-crush and then extrude the food when extracting the juice of the food to be tested, so as to separate the solid and liquid. The liquid therein falls downward through the filter holes of the filter frame, and the solid is blocked. Then, the whole filter frame can be slid out from the inside of the extraction box, which is convenient for subsequent cleaning and further reduces the difficulty of subsequent cleaning.

[0006] To achieve the above object, the utility model is realized by the following technical solutions: A juice extraction device includes a bottom plate, and an extraction mechanism is arranged above the bottom plate.

The protective sleeve can be made of sponge material, which can improve the comfort when pulling the filtering frame to slide through the handle. Two symmetrically arranged guide plates are fixedly connected to the inner wall of the extraction box.
