Abstract: The disclosure discloses a method for co-production of gelling and emulsifying pectins from chicory/Jerusalem artichoke pulp, including raw material pretreatment, extraction, filtration, concentration, alcohol precipitation, and drying. According to the cell wall structure and tissue characteristics of chicory/Jerusalem artichoke pulp, the disclosure targetedly adopts the salt extraction and the dilute acid extraction to sequentially produce gelling and emulsifying pectin products. The gelling chicory/Jerusalem artichoke pectin has characteristics of simple molecular structure, high purity, low degree of acetylation (DA), and high gel strength; and the emulsifying chicory/Jerusalem artichoke pectin has excellent emulsifying properties. The extraction method for chicory/Jerusalem artichoke pectin in the disclosure can provide two types of pectin at the same time, broaden the application range of chicory/Jerusalem artichoke pectin, and improve the processing utilization of chicory/Jerusalem artichoke pulp.

Abstract: A filter apparatus includes a filter unit and a conveying unit. The filter unit is configured to filter a liquid to-be-filtered, and the liquid to-be-filtered enters the filter unit in a first tangent-line direction of the filter unit. The conveying unit extracts a liquid to-be-conveyed from a periphery of the filter unit to output a conveyed liquid, and the conveyed liquid enters the filter unit in a second tangent-line direction of the filter unit.
