Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a negative pressure filtering device for spice extract. Background Art

[0002] Filter paper-based liquid negative pressure filtration devices perform excellently in the filtration process of spice extracts, effectively removing impurities such as tiny particles, plant debris, and bacteria from the extract, ensuring the purity and quality of the final product. Key components of this device include a pump system, filter paper, and a filter container. To facilitate filter paper replacement, the filter paper is typically placed directly into the filter container. While this structure facilitates replacement, it is difficult to ensure a tight seal between the filter paper and the filter container, and liquid bypass or leakage can easily occur at the edges of the filter paper, resulting in poor filtration results. Therefore, improvements are necessary. Utility Model Content
