Fresh fruit juice is first filtered through a 5-10μm precision pre-filter to remove large-particle impurities (e.g., pulp residues, fruit stones, suspended solids), protecting subsequent membrane elements from clogging and extending their service life.
Ultrafiltration (UF) Membrane Clarification: Equipped with ultrafiltration membranes with a molecular weight cut-off of 10,000–50,000 Da or microfiltration (MF) membranes with a pore size of 0.1–1 μm. Under low pressure (0.2–0.4 MPa) and room temperature (25–35℃), colloids (e.g., pectin, proteins), fine pulp particles, and other impurities are retained by the membrane.
Membrane Sterilization: Synchronously achieves microbial removal via the same membrane system—bacteria (E. coli, Salmonella), yeasts, molds, and spores (size >0.01 μm) are completely intercepted, with a sterilization rate of ≥99.99%.
Nanofiltration (NF) Membrane Pre-Concentration: The clarified and sterile juice is pumped into the nanofiltration membrane module (operating pressure: 0.8–1.5 MPa). The membrane selectively retains sugars, organic acids, and flavor compounds, pre-concentrating the juice from 10%–15% soluble solids to 25%–30%.
Vacuum Low-Temperature Final Concentration: The pre-concentrated juice enters the vacuum low-temperature concentrator (40–60℃) for further concentration to 65%–70%, reducing energy consumption by 30%–50% compared to traditional single heat concentration.
