Mango Fruit Defect Detection Grading System

The fruit grading system equipped with a high-precision mango defect detection machine, it enables fully automated, non-contact, and high-standard quality sorting and grading; it optimizes post-harvest processing, standardizes product output, and enhances added value.

Objectives of Mango Grading:

First, to eliminate defective mangoes—such as those with skin damage, internal spoilage, or insufficient maturity—thereby preventing spoiled fruit from contaminating batches of high-quality produce.

Second, to classify mangoes into grades (e.g., premium and secondary) based on standardized criteria regarding size, maturity, and visual quality, enabling tiered pricing and increased revenue.

Third, to replace manual sorting, thereby avoiding inconsistencies in grading standards caused by visual fatigue or subjective human judgment.

Mango Fruit Grading System Working Principle:

This mango grading system utilizes a dual-detection system combining AI machine vision and near-infrared (NIR) spectroscopy, enabling fully automated, integrated operations without manual intervention. It autonomously handles processes such as feeding and positioning, data acquisition, intelligent analysis, and precision sorting. With a processing speed of just 0.3 seconds per mango, it is ideally suited for continuous, high-volume industrial production.

Fruit Grading System Features:

The system features an optimized CNN-based vision algorithm that enhances the mango defect detection machine’s recognition capabilities, achieving a defect detection rate of up to 99.2% and a ripeness grading error of less than 1.5%.
Highly adaptable across varieties, the complete fruit grading system supports parameter adjustment, allowing it to handle mangoes of varying skin colors, sizes, and types.
The machine features a flexible silicone conveyor bed and a pneumatic, non-contact air-jet sorting mechanism; the sorting process causes no skin abrasion or crushing damage, making it ideal for the non-destructive grading of premium mangoes.

Single-line hourly production capacity ranges from 1 to 10 tons; the fruit grading system can integrate with mango washing machine, air-drying machine, and packaging equipment to create a fully automated mango processing plant.
