This production line is specially designed for high-protein milk beverages (e.g., Nutritious Fast Line, Fruit Granule Milk You, etc.), integrating three core technologies: two-phase emulsification, aseptic cold filling, and flavor embedding. It realizes full-process automation from raw material processing to post-sterilization. The protein stability is ≥98%, complying with GB 21732-2008 National Standard for Milk-containing Beverages and FDA 21 CFR Part 131.
Core Systems and Technological Innovations
| Module | Technical Description | Solved Pain Points |
| 1. Dual-protein Pretreatment | Step-by-step dissolution of milk protein/soy protein (60℃ gradient hydration to prevent caking) | Protein aggregation and precipitation |
| 2. Nanoscale Emulsification | Two-stage homogenization (40MPa+20MPa) + phospholipid embedding technology (particle size ≤0.5μm) | Fat floating and layering |
| 3. Online Fruit Particle Addition | Servo metering injection system (fruit particle integrity ≥90%, particle size adjustable between 3-8mm) | Fruit particle crushing/distribution unevenness |
| 4. Aseptic Cold Blending | Ultra-high temperature instantaneous sterilization (137℃/4s) → cooling to 25℃ for filling | Thermal nutrient loss |
| 5. Negative Pressure Filling | Dual-channel electronic valve filling (accuracy ±0.5%, residual oxygen ≤0.3%) | Vitamin oxidation |
| 6. Instant Post-sterilization | Spray-type pasteurization (95℃/10min → gradient cooling) | Secondary pollution risk |
| 7. Intelligent Capping | Torque closed-loop control (capping pass rate ≥99.8%, compatible with PP bottles/Tetra Rex) | Leakage/swelling |
| 8. Laser Coding | Dual-position traceability codes on cap and bottle (PDA scanning for batch/production line/operator) | Low efficiency of quality traceability |
