The Apple Juice Plant Sterilization, Clarification & Concentration Equipment is an integrated high-efficiency processing system designed for fruit juice deep processing. It integrates three core functions: impurity removal, sterilization, and concentration. Based on advanced membrane separation technology and low-temperature concentration technology, the system solves industry pain points such as juice turbidity, short shelf life, and nutrient loss.
It is widely applicable to various fruit juices (e.g., orange, apple, mango, dragon fruit) and functional fruit drinks, delivering clear, sterile, and high-concentration final products while maximizing the retention of natural flavors and vitamins. This equipment meets global food safety standards such as FDA, SC, and EU regulations.
Fresh fruit juice is filtered through a 5-10μm precision pre-filter to remove large-particle impurities, protecting subsequent membrane elements from clogging.
Ultrafiltration (UF) Membrane Clarification: Uses membranes with a molecular weight cut-off of 10,000–50,000 Da. Colloids, pectin, and proteins are retained while nutrients pass through.
Membrane Sterilization: Achieves complete microbial removal (E. coli, yeasts, molds) with a sterilization rate of ≥99.99% without thermal damage.
Nanofiltration (NF) Pre-Concentration: Selectively retains sugars and organic acids, pre-concentrating juice to 25%–30% soluble solids.
Vacuum Low-Temperature Final Concentration: Further concentrates juice at 40–60℃ to 65%–70% soluble solids, saving 30%–50% energy compared to traditional heat methods.

The system utilizes high-precision membrane filtration (UF/MF) that physically intercepts bacteria, yeasts, and molds based on pore size (0.01-1μm), achieving a 99.99% sterilization rate at room temperature.
By operating under vacuum at 40–60℃, the juice avoids thermal damage, preserving natural vitamins, enzymes, and delicate flavor compounds that are usually lost in traditional boiling methods.
Yes, the pretreatment and UF stages are specifically designed to manage pectin and pulp residues, making it suitable for a wide range of fruit types from clear apple juice to thicker mango purees.
The combination of Nanofiltration (NF) pre-concentration and vacuum concentration reduces overall energy consumption by 30%–50% compared to systems relying solely on thermal evaporation.
All materials in contact with the juice are made of 304/316L stainless steel or food-grade PVDF, complying with global standards including FDA, EU, and SC regulations.
The system includes an integrated CIP (Clean-in-Place) unit that automatically circulates cleaning reagents through the membranes and pipelines to prevent fouling and extend equipment life.
