This production line features an innovative dual-mode intelligent switching system for both fresh-squeezed and concentrated processing, enabling flexible production of three product categories: NFC (Not-From-Concentrate) orange juice, FC (Frozen Concentrate) orange juice, and pulpy orange beverages. With a daily processing capacity of 200 tons of fresh fruit, it utilizes low-temperature physical processes to achieve ≥95% vitamin C retention rate, complying with GB 17325, FDA 21 CFR Part 120, and other international food safety standards.
Core Systems & Innovative Technologies
| Module | Technical Specifications | Dual-Mode Compatibility |
| 1. Intelligent Sorting & Washing | Sugar degree detection + 360° brush washing (Pesticide degradation rate ≥90%) | Universal for both modes |
| 2. Whole-Fruit Extraction | Brown extractor (Yield rate ≥82%, bitter compounds ≤5ppm) | Fresh-squeezed mode only |
| 3. Ultrafiltration Separation | Ceramic membrane molecular sieve (Retains pulp particle size 40-100μm, removes seed fragments) | Universal |
| 4. Aroma Recovery | Vacuum falling-film aroma capture tower (Recovery rate ≥92%, for concentrate reconstitution) | Concentrated mode core |
| 5. Pasteurization | Tubular multi-stage sterilization (Fresh: 72℃/15s; Concentrate: 88℃/30s) | Independent dual-process control |
| 6. Vacuum Concentration | Quadruple-effect falling-film evaporator (45% energy saving, solids: 12°Bx→65°Bx) | Concentrated mode only |
| 7. Aseptic Filling | Negative-pressure filling + N₂ protection (O₂ residual ≤0.5%, compatible with PET/Tetra Pak/aseptic bags) | Universal |
| 8. CIP/SIP | Full-pipeline H₂O₂ sterilization (Real-time microbial risk monitoring) | Mandatory for both modes |
