Jujube grading packing line installed in Australia

The Challenge: Moving Beyond Size Grading

The customer, one of Australia’s largest jujube growers, needed a sophisticated solution to move beyond simple size grading. Their primary challenge was managing three distinct fruit classes simultaneously to maximize market value:

• First Grade – Premium fruit requiring precise size grading into four sub-categories.

• Second Grade – High-quality fruit (approx. 15% of yield) still holding significant retail value.

• Juice Class – Lower-grade fruit destined for processing.

Standard inspection tables typically allow only one rejection category. The grower needed a customized interface where workers could manually divert “Seconds” and “Juice” grades into separate, automated streams without slowing down the primary grading line.

The Solution: A Highly Customized 15-Meter Processing Line

Our engineering team developed a bespoke jujube grading and packing line featuring several custom modifications to the standard 4-meter inspection station.

1. Tri-Channel Manual Inspection Table

A specialized inspection table with three separate exit hoppers on each side:

• Second Grade Stream – Fruits placed into end-hoppers drop onto a dedicated collection belt, leading to an automated weighing and boxing station.

• Juice Grade Stream – Fruits placed into center hoppers drop directly into collection tubs below.

2. Integrated Precision Weighing & Packing

The system handles various packaging needs from 3kg to 10kg boxes. Five integrated weighing stations ensure both First and Second-grade fruits are packed with 99% weight accuracy, ready for immediate market distribution.

3. Ergonomic & Space-Saving Design

Customized guardrails and elevated platforms on both sides of the inspection table optimize the facility’s footprint and ensure worker safety, while maintaining a high throughput of 2,000–3,000 kg/hour.
