ZS-GWF24 Automatic Multi-Head Weighing & Clamshell Fruit Filling System
The ZONESUN ZS-GWF24 is an automatic weighing and filling system designed for small fruits and similar free-flowing products packed into clamshells, trays and selected boxes. It combines an incline feeding conveyor, multi-head weighing unit, tray feeding, automatic filling and dual-lane conveying, with an automatic lid closing and pressing section for continuous packaging.
The system supports single-lane and double-lane configurations. The stated output is a reference range under suitable product, package and setup conditions; actual throughput and weighing performance depend on fruit size, shape, density, flowability, target weight, packaging format and machine settings.

How the Packaging Process Works
- Products are elevated by the incline feeding conveyor.
- The multi-head weigher portions the product to the preset target weight.
- Stacked trays or clamshells are released and transferred into the filling position.
- Weighed portions are discharged into the packaging containers.
- Filled containers move through the dual-lane conveyor.
- Hinged lids are guided into position and pressed closed before downstream handling.
System Components
Incline Feeding Conveyor
Continuously lifts and transfers products to the multi-head weigher for automatic portioning and filling. Feed stability is important for consistent weighing performance.
Multi-Head Weighing System
Weighs products according to the preset target weight and distributes portions for consistent filling. Actual weighing accuracy depends on the product characteristics, target weight and sensor configuration.
Stacked Tray Loading & Feeding System
Holds stacked trays and releases them one by one onto the conveyor to maintain a continuous packaging flow.
Automatic Weighing Filling System
Transfers weighed portions into trays or containers for efficient and repeatable product filling.
Dual-Lane Conveyor System
Provides stable horizontal conveying of filled containers for continuous downstream packaging operations.
Automatic Lid Closing & Pressing System
Guide rails position hinged lids, while the pressing mechanism applies closing pressure for secure closure during continuous packaging.
Best-Suited Applications
- Blueberry and cherry packaging
- Cherry tomato and cranberry packaging
- Jujube and similar small-fruit packaging
- Fresh produce portions packed by target weight
- Clamshell and tray-based retail packaging where the container format is compatible with the feeding and closing system
Performance & Compatibility Notes
- Weighing: The stated ±0.5–2.0 g range is a reference based on the weighing sensor configuration. Product characteristics and target weight can affect actual results.
- Speed: 15–25 bags/min for single lane and 30–50 bags/min for double lane are reference ranges, not guaranteed output for every fruit or package.
- Product handling: Fruit size, shape, surface condition, density and flow behavior should be evaluated before final configuration.
- Packaging: Clamshell/tray dimensions, lid geometry and container rigidity should be confirmed so the tray feeding, filling and lid-closing sections can be matched correctly.
- Utilities: The listed air pressure and consumption are machine-side references. Compressor capacity and site utilities should be checked against the final configuration.
Before Ordering
For a project quotation, provide the fruit type, typical piece size, target weight per package, desired output, clamshell or tray dimensions, package material, and whether single-lane or double-lane production is preferred. Sample testing is recommended when product shape, size variation or packaging geometry may affect weighing, feeding or closure performance.
FAQ
Can this machine package fruits other than the listed examples?
Potentially, if the product has suitable flow and handling characteristics. Final compatibility should be confirmed by sample testing.
Does the machine automatically weigh the fruit?
Yes. The multi-head weighing section portions the product to the preset target weight before discharge into the packaging container.
Does it support clamshell closing?
Yes. The listed configuration includes tray feeding and an automatic lid closing and pressing section. The exact container and lid format should be confirmed before ordering.
What determines the actual production speed?
Fruit characteristics, target weight, number of weighing heads, lane configuration, tray format, feeding stability and machine settings all affect actual throughput.
