Demeter AI Blueberry GraderAI-Powered 360° All-Around Precision Grading Intelligent sorting by color, size, firmness, and dehydration in a single pass, with multi-grade simultaneous output.

A custom roller system ensures high-efficiency processing while fully protecting the natural bloom, balancing throughput with fruit integrity.

Each blueberry is individually scanned and analyzed by transport rollers, enabling high-precision grading based on preset standards and parameters to ensure sorting consistency and reliability.

A high-capacity feeding system ensures even distribution and precise positioning of blueberries, reducing detection interference and bloom loss to maintain grading accuracy.

Self-developed AI deep learning algorithms continuously learn and optimize defect recognition capabilities.

High-resolution RGB camera + ring shadowless lighting for clear, uniform imaging.

Optional hyperspectral imaging system and air-cooled halogen lighting for deeper inspection.

Comprehensive defect detection based on color, size, shape, and texture:

• Color grading: Distinguishes dark blue, light blue, and unripe fruit for consistent appearance.
• Size grading: Supports diameter sorting (e.g., >12mm for premium fruit).
• Defect recognition: Accurately detects mold, shriveling, cracking, scarring, and other flaws.
• Soft fruit detection (optional): Analyzes internal moisture and sugar content.

Optimized structural design enhances durability and response speed, achieving precise ejection at high throughput while significantly reducing false rejection rates and operating costs.

15-inch industrial touchscreen: Intuitive human-machine interface with multi-language support and one-click switching of grading programs.

Comprehensive remote support: Enables remote access, real-time monitoring, and data dashboard viewing for smarter, more convenient maintenance.
