Final Lid Pressing System
Applies additional pressure to the closed tray lid, ensuring the integrated hinged lid is fully and securely snapped into place.

Key Features
✅ Integrated 6-Stage Automated Workflow: Combines fruit conveying → combination weighing → automatic tray feeding → fruit filling → guide-rail lid closing → final lid pressing in one continuous packaging line.
✅ 8-Head or 12-Head Configurations: 8-head achieves 32–48 boxes/min; 12-head achieves 55–72 boxes/min — selectable to match production throughput requirements.
✅ Gentle Fruit Discharge — Flexible Cushioning Flaps: Cushioning flaps on the discharge chute absorb impact during fruit release, helping minimize bruising and surface damage to delicate fruits.
✅ Multi-Head Combination Weighing: Automatically combines bucket contents to hit the target fill weight for accurate, consistent dosing into every tray.
✅ Automatic Tray Feeding: Continuously supplies empty trays to the filling station without manual placement, maintaining uninterrupted line operation.
✅ Two-Stage Lid Closure: Guide-rail snap-close followed by a final pressing station ensures every hinged tray lid is fully and securely engaged for retail-ready packaged fruit.
✅ SUS 304 Stainless Steel: Full stainless steel construction for corrosion resistance and easier cleaning in fresh produce processing environments.
