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):

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):

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:

  1. Empty box moves into position automatically

  2. Fruit fills until target weight is reached

  3. Belt stops – 1–2 extra pieces may drop due to inertia

  4. Full box moves out automatically

  5. Next empty box moves in

  6. (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
