Lab - grade hollow fiber membranes feature a high specific surface area and low energy consumption, with filtration pore sizes precisely tailored for juice systems (typically 0.1–1μm). They enable juice clarification experiments at room temperature, efficiently retaining pectin, suspended particles, microorganisms, and other impurities in fruit juices while maximizing the preservation of active ingredients such as vitamins and polyphenols, avoiding nutrient loss and flavor damage caused by traditional thermal clarification processes.
Suitable for small - scale and pilot - scale clarification of small batches of fruit juices (e.g., apple juice, grape juice, orange juice), they support cross - flow filtration mode to effectively reduce membrane fouling. After experiments, flux can be restored through simple backwashing, facilitating the optimization of clarification process parameters (e.g., pressure, temperature, feed liquid flow rate) for different juice systems and providing reliable data support for industrial - scale juice clarification processes.
