FstSort provides punnet packing machines for blueberries, cherry tomatoes, and jujubes. The system can work independently or integrate with sorting and grading lines for efficient small fruit packing.
The FstSort small fruit punnet packing machine is designed for blueberries, cherry tomatoes, jujubes, litchis, longans and other small fruits that require gentle handling and accurate weight filling.
This system can work as a standalone packing line or be integrated after a FstSort sorting and grading line. It helps packhouses complete manual inspection, automatic weighing, punnet or clamshell filling, checkweighing, labeling and finished pack collection in one smooth workflow.
Product Overview
For small fruits, packing accuracy and gentle handling are just as important as grading quality. After fruit has been
cleaned, sorted or graded, the next step is to fill each punnet or clamshell with consistent weight while reducing product damage and labor cost.
This 8-head linear weigher packing system is built for small round fruits with a diameter below 40mm. It distributes fruit through 8 weighing channels, selects the best weight combination, and fills punnets or clamshells according to the target weight.
The system is suitable for packhouses that need either:
- A standalone small fruit packing machine
- A packing module after sorting and grading
- A complete small fruit sorting, weighing and packing line
- A customized packing solution for different box sizes and fruit types
Typical Applications
This punnet packing machine is suitable for:
- Blueberry
- Cherry tomato
- Winter jujube
- Litchi / lychee
- Longan
- Small apricot
- Small walnut
- Other small round fruits within 40mm diameter
How It Works With FstSort Lines
When used with a FstSort sorting or grading system, the punnet packing machine can be placed after the grading
section. Fruits are transferred from sorting or grading to inspection, weighing, filling, checkweighing and labeling.
This helps customers build a more complete post-harvest workflow:
Sorting / Grading → Inspection → Weighing → Punnet Filling → Checkweighing → Labeling → Finished Packs
For customers who already have upstream sorting equipment, the system can also be used independently as a dedicated
packing line.
