roduct Overview – Complete Box & Carton Filling Solutions
After grading, your fruit needs to be packed efficiently. Our box and carton filling systems integrate seamlessly with any grading line that has takeout belts – including roller graders, electronic weight sorters, and optical sorters.
We offer three levels of automation to match your volume, budget, and labor availability.
Model | Automation Level | Best for |
|---|---|---|
Manual Filler | Hand packing | Small farms, low volume, tight budget |
Semi-Automatic Filler | Automatic filling + manual box change | Medium packers, moderate volume |
Fully Automatic Filler | Fully automatic filling + box change + sealing | Large packers, high volume, export |
How It Works – Integration with Your Grader
The box filler connects directly to the takeout belts of your existing grader:
Grader (roller/weight/optical) → Takeout belts → Box filler → (optional) Sealing machine
Graded fruit exits through takeout belts
Fruit is directed into waiting boxes or cartons
Weighing system stops filling when target weight is reached
Full boxes are moved out – empty boxes move in
Model 1 – Manual Box Filler
Description:
Operators manually place boxes under each grading outlet. Fruit fills the box while the operator monitors weight on a digital scale. When target weight is reached, the operator replaces the box.
Best for:
Small farms
Multiple grade outlets (3~5 grades)
Low budget
Low labor cost
Specifications (customizable):
Parameter | Range |
|---|---|
Number of stations | 3–6 (depends on grade outlet) |
Weighing method | Digital scale (operator monitored) |
Target weight range | 2 – 25 kg |
Box type | Cartons, plastic crates, wooden boxes |
Integration | Takeout belts from a grader |
Model 2 – Semi-Automatic Box Filler
Description:
Fruit fills automatically into the box while a load cell monitors weight. When target weight is reached, the belt stops automatically. The operator then replaces the full box with an empty one and restarts the belt.
Best for:
Medium packers (2–8 t/h)
Reducing labor without full automation
Boxes 2kg and above
Specifications (customizable):
Parameter | Range |
|---|---|
Number of stations | 3–6 (you choose how many) |
Weighing method | Load cell (automatic stop at target weight) |
Accuracy note | Belt inertia adds 1–2 pieces after stop |
Recommended box size | > 2 kg |
Target weight range | 0.5 – 25 kg (but <2kg not recommended) |
Box type | Cartons, plastic crates |
Operation | Automatic fill + manual box change |
Integration | Takeout belts from a grader |
Model 3 – Fully Automatic Box Filler
Description:
The fully automatic system handles everything: filling, weighing, box indexing, and full box discharge. It can be connected to an automatic sealing machine for a complete packing line.
Operation sequence:
Empty box moves into position automatically
Fruit fills until target weight is reached
Belt stops – 1–2 extra pieces may drop due to inertia
Full box moves out automatically
Next empty box moves in
(Optional) Full box enters sealing machine
Best for:
Large packers (8+ t/h)
Export orders requiring consistent box weights
High labor cost regions
Boxes 2kg and above
Specifications (customizable):
Parameter | Range |
|---|---|
Number of stations | 4+(you choose how many) |
Weighing method | Load cell (automatic stop at target weight) |
