Fstsort passion fruit grading machine: choose roller grader (4t/h, 3–6 grades) for high speed, or electronic weight sorter (±2g, 6–12 exits, ~20,000 pcs/h/lane) for soft handling. Customizable lanes & exits. Gentle design for fresh fruit. Get quote.
Product Overview – Two Sorting Technologies for Passion Fruit
This Fstsort passion fruit grading machine is designed for accurate sorting with large capacity, while maintaining gentle handling for fresh fruit. We offer two sorting technologies – you choose based on your priority: speed or gentleness.
Technology | Principle | Best for | Handling |
|---|---|---|---|
Roller Grader | By diameter (straight rollers) | High volume, fast processing | Gentle, but less soft than electronic |
Electronic Weight Sorter | By weight (±2g accuracy) | Premium packing, export grades, very fragile fruit | Very gentle – soft padding at all points |
💡 Which one should you choose?
Roller grader – higher speed (3t~4t/h), lower cost, proven design
Electronic sorter – softest handling, weight accuracy, multi-lane capability
Both machines share these common features:
Gentle handling for fresh fruit
Variable speed – electrically adjustable
Grade sizes adjustable – wide choice to suit your needs
Easy to move – wheels on the legs (roller grader)
Inspection tables – belt or roller conveyor for manual sorting
Soft Handling – Standard on Both Machines
We understand that passion fruit is delicate. Both machines are designed to minimize damage:
Feature | Roller Grader | Electronic Sorter |
|---|---|---|
Straight roller design | ✅ Gently rotates and orients fruit | ❌ Not applicable |
Soft mat at slope exits | ✅ Optional | ✅ Standard |
Foam rubber on elevator | ❌ No | ✅ Yes |
Elastic joints at connections | ❌ No | ✅ Yes |
Sponge-padded packing tables | ❌ No | ✅ Yes |
Rounded weighing cups | ❌ No | ✅ Yes |
Roller grader – A straight roller is used to gently rotate and orient the fruit until it separates onto the conveyor at the appropriate distance. The fruit is spread on the conveyor according to size.
Electronic sorter – Extra soft protection (foam rubber, elastic joints, sponge padding) for very fragile fruit.
Option 1 – Roller Grader (Diameter Sorting)

Key features:
Straight roller design – gently rotates and orients fruit
Variable speed – electrical adjustment
Grade sizes adjustable – wide choice to suit your needs
Easy to move – wheels on the legs
Inspection tables – belt or roller conveyor for manual sorting
Discharging conveyors – gentle, durable belts; soft mat can be added at bottom of each slope exit to reduce damage
Application: Passion fruits, bell peppers, potatoes, carrots, mangosteen, etc.

Frequently Asked Questions
Key questions customers usually ask before choosing this solution.
Is the roller grader gentle enough for fresh passion fruit?+
The roller grader uses straight rollers to gently rotate and orient fruit, and we can add soft mats at slope exits to reduce damage. However, for fully ripe, very soft passion fruit sold fresh in premium markets, we recommend the electronic sorter.
Can I add soft mats to the roller grader exits?+
Yes. We can add soft mat at bottom of each slope exit to reduce damage on the roller grader.
Can I add an automatic box packaging system?+
Yes. As shown in our Australian customer project, we can integrate bin tipper + elevator + inspection table + size grader + automatic box fill and weigh packaging.
