Quick walnut kernel sorting machine with shadowless lamp and centroid algorithm, delivering export-grade accuracy at 280–360 kg/h

Description

Export buyers enforce strict kernel quality standards. Failing an inspection wastes an entire shipment. The MHT02-0412C quick walnut sorting machine meets export-grade requirements at every run. Four HD cameras and an AI classifier grade kernels against 15 defined categories. Processing reaches 280-360 kg/h. You ship product that passes international inspections consistently and protect your export relationships.

Overview

Export markets leave no room for grade inconsistency. A rejected container costs far more than a new machine. The MHT02-0412C builds export-grade quality directly into your processing line. The deep learning system recognizes Extra Light Halves, Light Amber, Amber, and all other commercial categories with high accuracy. Your product meets buyer specifications batch after batch. The shadowless lamp eliminates lighting errors that cause false rejections. The centroid algorithm targets each kernel precisely so the right grade reaches the right outlet. Every decision the AI makes is logged and trackable. That data supports your quality documentation and buyer audits. The machine runs at commercial pace without sacrificing accuracy. For processors supplying European and North American markets, the MHT02-0412C provides the grading precision those buyers require.

Key Advantages

1. Export-Grade Accuracy — AI classifies 15 kernel grades to the specifications European and North American buyers require. Rejection rates fall.

2. Traceable Quality Data — The system logs grading decisions in real time. Use that data to support buyer audits and quality records.

3. Shadowless Illumination for True Color — The lamp system eliminates shadows. Cameras read true kernel color. False positives drop significantly.

4. Scalable from Pilot to Commercial — Start at 280 kg/h and grow your export volume without replacing equipment. The machine adapts to increased throughput demands.

Technical Features

• Shadowless lamp illumination — eliminates optical interference; cameras capture accurate kernel color every time

• Deep learning neural network — trained on export-grade categories; classifies to international buyer specifications

• Centroid algorithm — pinpoints each kernel's geometric center for precise ejection without cross-grade contamination

• Real-time data monitoring — grading log available at the control panel for quality records and buyer documentation

• Special solenoid valve — fast, accurate actuation keeps grade separation sharp at commercial throughput rates

• Teflon conveyor — food-safe, non-reactive surface; suitable for export-certified processing environments

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.
