Imprecise ejection wastes product. When good kernels land in the wrong bin, you lose premium grade yield. The MHT02-0412C walnut kernel sorter uses a centroid algorithm to calculate each kernel's exact geometric center before ejection. The solenoid valve fires at precisely the right point. Every kernel goes to its correct outlet. Your premium yield improves with every batch.

Overview

Sorting accuracy has two components. Classification accuracy is how correctly the AI assigns a grade. Ejection accuracy is how precisely the machine places the kernel in the right outlet. Both must be high. The MHT02-0412C addresses ejection accuracy through its centroid algorithm. The system calculates each kernel's geometric center from the four-camera image data. The solenoid valve fires at the exact moment the kernel's center crosses the ejection point. This precision minimizes the chance that a kernel deflects into an adjacent outlet by mistake. The result is clean grade streams with low cross-contamination. For processors selling premium Light Halves or Extra Light Halves, even one percent improvement in ejection accuracy translates directly into revenue. Fewer premium kernels end up in lower-grade bins. Your yield from top categories rises without changing anything about your raw material.

Key Advantages

• Centroid Algorithm for Precision Ejection — The system maps each kernel's center and fires ejection at the optimal moment. Grade boundaries stay sharp.
• Higher Premium Grade Yield — Fewer premium kernels misroute to lower bins. Your Light Halves and Extra Light Halves yield improves per batch.
• Integrated All-in-One Design — Camera, algorithm, and valve work as one system. No external calibration equipment is needed.
• Durable Industrial Solenoid Valve — The high-frequency valve maintains ejection timing precision over thousands of operating hours.

Technical Features

• Centroid algorithm — maps each kernel's geometric center from four-camera data; drives precise ejection targeting
• Special high-frequency solenoid valve — fires at the exact centroid-calculated ejection moment; minimal misdirection
• 4 HD industrial cameras — supply the multi-angle image data the centroid algorithm needs for accurate center calculation
• Deep learning AI — works alongside the centroid system; classification and ejection accuracy reinforce each other
• 12 adaptive outlets — tight grade boundaries maintained by centroid-driven ejection precision
• Real-time monitoring — ejection events logged alongside grade data; supervisors can review accuracy metrics

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.
