Avocado Sorting & Grading machines Precision and Efficiency

The Avocado Sorting & Grading Machine is an automated production line that integrates cleaning, drying, defect detection, weight/size/color/internal quality grading, and packaging, providing a standardized, scalable solution for avocados from post-harvest processing to retail.

Operating Principle

The equipment features a modular design and is typically composed of five systems: loading, conveying, sensor detection, grading execution, and data management.

Core Technical Features

The equipment's modular structure allows for flexible configuration based on customer production capacity and grading standards.

The system supports simultaneous multi-channel operation, with a single-line throughput of up to 5 tons per hour and continuous, stable operation for over 16 hours.

The grading module utilizes a continuously adjustable robotic arm and guidance system, enabling simultaneous sorting based on up to eight parameters, including weight, quality grade, and size. Sorting accuracy reaches ±2 grams, ensuring consistent grade determination and significantly reducing manual sorting errors. The equipment can be directly integrated with packaging lines or labeling systems, enabling integrated post-harvest processing.

Advantages

• High-precision sorting: Utilizing high-resolution optical sensors and near-infrared spectroscopy technology, it simultaneously detects weight (±2 gram accuracy), size, color, surface defects, and maturity.
• Excellent production efficiency: A single-line processing capacity of 3-5 tons per hour is achieved, supporting 20 hours of continuous and stable operation to meet large-scale processing needs.
• Excellent durability and reliability: The main structure is constructed of food-grade 316 stainless steel, and key components are IP65-rated for high-humidity environments.
• Flexible Configuration Options: The modular design supports customized configuration and is compatible with a variety of avocado varieties (Hass, Fuerte, etc.).

Typical Complete Line Process (One-Stop Optional Configuration)

Bubble Surfing Cleaning → 2. Roller Brush + High-Pressure Spray → 3. Centrifugal/Hot Air Drying → 4. (Optional) Waxing + Secondary Drying → 5. Electronic Weighing and Grading → 6. Automatic Packaging or Cartoning → 7. Cold Chain Storage.

The avocado grader utilizes reliable optical inspection technology and a mechanical execution system to significantly improve sorting efficiency and fruit commercialization rate, reduce post-harvest losses, and provide sustainable technical support for the avocado industry.
