Customizable Grain Color Sorting Equipment with FPGA Processor and 3D Identification

So you’ve got a grain mill running three shifts and you’re trying to separate discolored rice from a batch that’s been sitting too long in a humid silo—we’ve all been there, and what this machine does is it lets you dial in exactly the color thresholds you need, so you’re not wasting good grain on a too-strict setting or letting bad ones slip through, and we can customize the vial sizes for your sample cups and even the labeling if you want your batch numbers printed right on the packaing.

It’s got 63 channels, which is pretty much overkill for most setups but gives you room to sort multiple grains in one pass, and the 5400-pixel CCD camera from Toshiba scans from both sides while the American FPGA processor handles the image data in real time—that’s about 0.5kw of power draw at 220v, and the whole thing weighs 320 kg with dimnesions of 914 by 1536 by 1760 mm, so you’ll need a forklift to get it into position, but the touch panel supports about a dozen languages and SMC filters from Japan keep the air lines clean for those high-frequency solenoid valves.

We’ve seen it work great for rice, wheat, corn, beans, peanuts, and tea—basically anything with a consistent color profile—but it’s not suited for sticky or wet grains straight from the field, because the vibratory feeder will clog and you’ll be cleaning out the chute every 20 minutes or so, and the 99.99% sorting accuracy is real but only if you keep the infeed rate under 1500 kg per hour (usually you’ll run it at 800 to 1000 for best results).

Anyway, lead time is about 4 weeks for a standdard unit (check on the custom vial sizes and labeling—that can add 10 days or so), and we usually have stock, but confirm before you order because the GS and CE certifications mean each unit gets inspected before shipping, and you’ll get a COA with the batch number and the HPLC data on the calibration run.
