Application

Ideal for automatic weighing, portioning, filling, and clamshell tray packaging of small fruits, especially products requiring both accurate target weights and gentle handling.

The source document specifically identifies: Blueberries, Cherry Tomatoes, Cherries, Cranberries, Jujubes, Other compatible small fruits.

The machine is particularly suitable for small, high-value, and delicate fruits, because its low-drop filling and flexible cushioning structure are designed to reduce impact, bruising, and skin damage during packaging.

Automatic Tray Feeding

Automatically feeds empty trays into the packaging line for continuous filling and packing.

Gentle Fruit Discharge

Flexible cushioning flaps reduce impact during discharge, helping minimize bruising and damage to delicate fruit.

Multi-Lane Fruit Conveying

Multiple lanes organize and continuously convey fruit to the weighing section for efficient processing.

Multi-Head Combination Weighing

The multi-head weighing system automatically combines target portions for accurate and consistent fruit dosing.

Guide-Rail Lid Closing

Guide rails automatically press and snap the integrated hinged lid securely onto the tray for continuous and hygienic packaging.

Final Lid Pressing System

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

Why Choose the ZONESUN ZS-GWF15?

✅ Multi-Head Combination Weighing — Accurate Target Weight Control: Multiple independent weighing hoppers simultaneously measure fruit portions, while the control system selects the combination closest to the required target weight for accurate and consistent portioning.

✅ 8-Head / 12-Head Options — Match Different Production Capacities: The ZS-GWF15 is available in two documented weighing configurations: 8 heads for 32–48 boxes/min and 12 heads for 55–72 boxes/min, allowing the system to be selected according to production requirements.

✅ Gentle Fruit Discharge — Protect Delicate Products: Flexible cushioning flaps reduce impact during fruit discharge, helping minimize bruising and damage to sensitive fruits such as blueberries and cherries.

✅ Low-Drop Product Handling — Reduced Bruising & Skin Damage: The fruit handling structure uses a low drop height and flexible cushioning to reduce collision and impact during discharge, helping protect delicate fruit surfaces.

✅ Multi-Lane Fruit Conveying — Organized & Continuous Feeding: Multiple conveying lanes organize fruits and continuously transport them toward the weighing section, improving feeding efficiency and maintaining an orderly product flow.

✅ Automatic Tray Feeding — Continuous Packaging Operation: Empty trays are automatically supplied to the packaging section, reducing manual tray placement and supporting continuous weighing and filling production.

✅ Guide-Rail Lid Closing — Mechanical Snap-Fit Closure: Instead of heat sealing, the machine uses guide-rail physical pressure to press the integrated hinged lid downward and snap it securely onto the tray.

✅ Final Lid Pressing — More Reliable Clamshell Closure: After the integrated hinged lid is initially closed by the guide rails, a final pressing system applies additional pressure to ensure that the lid is completely and securely snapped into place.

✅ Up to 72 Boxes/Min — Efficient Small-Fruit Packaging: The 12-head configuration reaches a documented maximum of 72 boxes/min, providing efficient packaging capacity for commercial fresh-fruit operations.
