High-Capacity Potato Size Sorter

I need a complete design—and, if you can, a prototype plan—for an automated potato sorter that separates crop primarily by size but can also flag colour blemishes, shape inconsistencies and any bruising or damage. Target throughput is about 10 tonnes per hour, so the system has to run fast and stay reliable in a dusty, damp pack-house environment.

The core assignment is the engineering: conveyor layout, singulation, sizing mechanism (rollers, screen, optical gates—whatever you know will achieve clean size grades), plus a vision or sensor module that triggers reject lanes for defective tubers. I’m flexible on whether you prefer PLCs, Arduino-class micro-controllers or an industrial PC, so long as replacement parts are easy to source and software is clearly documented.

Deliverables
• 3-D CAD files and 2-D fabrication drawings
• Control-panel schematic, wiring diagram and PLC/MCU code
• Bill of materials with part numbers and indicative lead times
• Commissioning checklist and basic operator manual
• Optional: costed prototype or manufacturing plan

I will review by running your drawings through my fabricator and simulating the control sequence; final sign-off comes after the documentation matches the required 10 t/h rating and the defect-detection module correctly identifies sample blemishes we’ll provide.
