Smart walnut kernel sorting machine with centroid algorithm and high-frequency solenoid valve, removing contaminants and maximizing grade yield at 280–360 kg/h

Description

Unsorted walnut batches contain shriveled kernels, shell fragments, and septum that lower the value of every bag. Selling mixed-quality batches forces buyers to discount the whole lot. The MHT02-0412C quick walnut sorting machine removes contaminants and grades the good product simultaneously. It processes 280-360 kg/h. You sell clean, graded product at better prices with less waste.

Overview

Waste in walnut processing comes in two forms. Physical waste is the shell, septum, and shriveled kernels that must be removed. Economic waste is the price reduction you accept when good kernels ship mixed with poor ones. The MHT02-0412C addresses both at once. The deep learning AI identifies and separates all 15 kernel categories in one pass. Shell fragments go to their outlet. Shriveled kernels go to theirs. Light Halves go to the premium bin. You lose nothing that has value. You ship nothing that reduces value. The centroid algorithm ensures ejection hits the right target. Cross-contamination between grade streams stays minimal. For cooperatives managing variable raw material quality, this precision sorting transforms a low-value mixed batch into multiple high-value grade streams. That single improvement can raise your average revenue per kilogram significantly.

Key Advantages

1. Remove Contaminants in One Pass — The AI separates shell, septum, and shriveled kernels simultaneously with good product. No manual picking required.

2. Higher Price per Kilogram — Selling clean graded product instead of mixed batches commands better prices from buyers.

3. Precise Ejection Minimizes Cross-Grade Waste — The centroid algorithm targets ejection accurately. Good kernels do not end up in the reject bin by mistake.

4. Ability to Serve Multiple Buyer Segments — Separate grade streams let you sell Light Halves to premium buyers and lower grades to processors concurrently.

Technical Features

• Deep learning neural network — detects and separates 15 kernel categories including shell, septum, and shriveled kernels

• Centroid algorithm — calculates kernel center for precise ejection; minimizes misdirected good product

• 12 multi-grade adaptive outlets — each category routes to its own collection bin in a single pass

• 4 HD cameras — multi-angle imaging captures shell fragments and partition material that single-camera systems miss

• High-frequency solenoid valve — fast, precise actuation supports accurate ejection at commercial throughput rates

• Real-time monitoring display — shows grade volume data live so operators see output quality as it builds

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.
