Soybean milk filtering device and soybean milk filtering method thereof

Abstract

The invention relates to a soybean milk filtering device and a soybean milk filtering method thereof. The soybean milk filtering method comprises the steps: in a forward rotation stage of a motor, ribs rotate towards a dreg blocking plate to propel and extrude bean dregs, the soybean milk flows to a soybean milk collecting part through a backflow filtering gap, and the bean dregs are deposited in a dreg storing groove; and in a reverse rotation stage of the motor, the ribs move rotatably to propel the bean dregs to be extruded and discharged towards the direction of a dreg outlet along a spiral groove, and the soybean milk flows to the soybean milk collecting part through the backflow filtering gap. Compared with the prior art, the soybean filtering device and the soybean filtering method thereof have the advantages that the filtering efficiency is high, the bean dreg content is low, the soybean milk yield is high and the like.

Description

technical field [0001] The invention relates to a filtering device and a filtering method, in particular to a soybean milk filtering device and a soybean milk filtering method. Background technique [0002] Existing soymilk filtration methods generally use sieves for manual filtration; or a sieve is embedded in the barrel to filter the slurry by using the gravity of the soymilk. However, the bean dregs filtered through the sieve generally have a relatively high slurry content, resulting in a large waste of soy milk; in addition, the filter screen is very easy to adhere to the bean dregs, and it is very difficult to clean; During the process, the meshes are easily blocked, resulting in a very slow filtration rate of the slurry. Making one soymilk often requires repeated filtering operations to obtain soymilk with a better taste.

Problems solved by technology

However, the bean dregs filtered through the sieve generally have a relatively high slurry content, resulting in a large waste of soy milk; in addition, the filter screen is very easy to adhere to the bean dregs, and it is very difficult to clean; During the process, the mesh is easily blocked, resulting in a very slow filtration rate of the slurry. It often requires repeated filtration operations to obtain a good-tasting soymilk.

[0003] The existing juice extractor field also discloses some screw propulsion extrusion juice extractors, including a propulsion screw, a squeeze barrel cooperating with the propulsion screw, a motor, a juice collection cavity and a filter part arranged at the front end of the squeeze barrel, through which the push screw Cooperate with the rotation of the extrusion barrel to push the crushing and extrusion, the crushed material slag and juice continue to advance along the gap between the propulsion screw and the extrusion barrel under the push of the propulsion screw, and go to the filter part for filtration, and the slag is discharged from the slag The juice is discharged through the filter part and flows to the juice collection cavity. It can be seen that the juice extractor must be equipped with another filter part structure to achieve the purpose of separating the juice residue, and it cannot completely change the traditional filter mode such as a filter or a sieve.
