Description

Uneven kernel feed causes sorting errors. When kernels arrive in clusters, cameras cannot evaluate each one individually. Misclassifications increase. The MHT02-0412C intelligent walnut sorting machine uses a high-frequency vibrator to spread kernels into a uniform single-layer flow before they reach the camera zone. Every kernel receives full four-angle evaluation. Accuracy stays high at full throughput.

Overview

Sorting accuracy depends on how kernels arrive at the camera. Overlapping or clustered kernels confuse AI classifiers and increase error rates. The MHT02-0412C addresses this at the feeding stage. The high-frequency vibrator breaks up clusters and spreads kernels across the full width of the Teflon conveyor. By the time a kernel reaches the four-camera scanning zone, it travels alone with clear space around it. The AI evaluates the kernel's full surface without interference from adjacent pieces. Ejection targets each kernel individually. Grade boundaries stay clean. This feeding consistency holds throughout the shift. The vibrator maintains uniform distribution whether the input hopper is full or nearly empty. For processors handling variable bulk density — wet walnuts, dried walnuts, mixed lots — consistent feed-layer quality protects accuracy across all material types.

Key Advantages

• Uniform Feed Layer at Camera Zone — The vibrator separates clusters before kernels reach the cameras. Every piece travels individually to the scan zone.
• Consistent Accuracy Across Material Types — Uniform feeding maintains evaluation quality for wet, dry, and mixed-density walnut batches.
• Stable Performance from Full to Low Hopper — Feed consistency holds whether the hopper is at capacity or near empty. No manual flow adjustment.
• Higher Ejection Accuracy — Single-layer feed means the solenoid valve targets one kernel at a time. Cross-grade ejection errors drop.

Technical Features

• High-frequency vibrator — breaks clusters and spreads kernels into a single-layer flow before the camera zone
• Teflon conveyor — smooth surface maintains single-layer flow without kernel tumbling or re-clustering
• 4 HD cameras — captures complete per-kernel data when uniform feed ensures each kernel travels alone
• Special high-frequency solenoid valve — individual kernel targeting at precise ejection point
• Deep learning AI — full-surface evaluation enabled by consistent single-layer feed quality
• 12 adaptive outlets — clean grade separation supported by accurate single-kernel ejection

Product Specification

Note: Output and air consumption may vary depending on raw material status, lane division, and finished material status. The maximum capacity per lane is 90 kg (calculated based on 90% halves and 10% quarter kernels). The above data is for reference only.
