The bottom edge of the inclined surface is fixedly and sealed to the inner ring edge of the horizontal annular connecting surface. The outer ring edge of the horizontal annular connecting surface is fixedly and sealed to the bottom edge of the filter mounting cavity (i.e., forming a sedimentation tank).

[0049] The diameter of filter hole 204 is greater than or equal to the diameter of the first filter hole 402, the diameter of the first filter hole 402 is greater than the diameter of the second filter hole 502, the diameter of the second filter hole 502 is greater than the diameter of the third filter hole 602, the diameter of the third filter hole 602 is greater than the diameter of the fourth filter hole 702, the diameter of the fourth filter hole 702 is greater than the diameter of the fifth filter hole 802, and the diameter of the fifth filter hole 802 is greater than the diameter of the sixth filter hole 902. Therefore, the pickled vegetables cannot pass through the first filter hole 402.

[0050] Working principle:

[0051] When it is necessary to clean floating debris from pickled vegetables, close the first valve 112, open the second valve 113, and open the third valve 114. Then, valve 114 is connected to the output of an external water source through a pipe. External water continuously enters valves 109 and 110 until the water level inside valve 101 is slightly lower than the level of valve 102 (for example, about 10cm). This causes the floating debris attached to the pickled vegetables to separate from the vegetables (the floating debris is on the water surface, while the pickled vegetables are underwater, and the density of the pickled vegetables is greater than that of water). The operator then uses a strainer to scoop up the floating debris. During the process of scooping up the floating debris, the water that sloshes on the surface can be drained through valve 102.

[0052] When it is necessary to clean the sediment, connect the input end of the second valve 113 to the output end of the external water source through the first pipe (remove the connection between 114 and the output end of the external water source). In use, the operator places the pickled vegetables into the cleaning chamber 109 through the top opening of 109. Then, open the second valve 113 and close the third valve 114, allowing the cleaning water in the cleaning chamber 109 to rinse the pickled vegetables (during this process, the operator can continuously turn the pickled vegetables). This rinses the pickled vegetables... Wastewater enters the sedimentation chamber 110 after passing through the first filter hole 402, the second filter hole 502, the third filter hole 602, the fourth filter hole 702, the fifth filter hole 802, the sixth filter hole 902, and the filter hole 204. The wastewater entering the sedimentation chamber 110 is guided by the inclined surface to the sedimentation tank at the bottom of the chamber for sedimentation. The first valve 112 is then opened to discharge the wastewater (the discharged wastewater can be collected in a wastewater collection tank and treated according to existing mature wastewater treatment standards). The flip door 105 (one end of which is hinged to one side of the retrieval and cleaning window, and the other end is rotatable and can be snapped onto the corresponding side of the retrieval and cleaning window) can be made of food-grade transparent material. Opening the flip door 105 allows for the cleaning of sediment in the sedimentation tank.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
