[0002] In recent years, with increased attention to health and improved living standards, high-quality, high-value-added products have become increasingly popular, and premium beverages and fruit and vegetable juices have gradually become staples of daily consumption. Simultaneously, food processing technologies and methods need corresponding changes and adjustments to maximize the preservation of nutrients and flavor compounds in raw materials during processing. Nutrient loss and the loss of aromatic substances are major technical challenges in fruit juice concentration. For decades, the international fruit juice industry has been dedicated to researching new concentration technologies to improve juice quality and reduce energy consumption.

[0003] In the production of fruit juice, after the pulping process, a residue removal process is required to remove coarse fibers from the pulp. The equipment used is a filter. Application number 202010587164.4 discloses a dragon fruit juice filtration device, which uses a hydraulic cylinder in conjunction with a filter tube to filter and remove residue from the juice. However, this technical solution requires separating the extrusion block from the filter tube before adding pulp. During this process, the pulp is easily oxidized when exposed to air, which is not suitable for filtering fruit juice. At the same time, there is a problem that the filter residue will stick to the inside of the filter tube after extrusion filtration, and it is time-consuming and laborious for personnel to clean the filter residue.
