Yes, actually I do know and have even owned such a device. In 1987 I attended a potato farm auction with the intent of purchasing a small potato digger.
The equipment fascinated me as I had never seen potato growing equipment nor none since. The grower had supplied potatoes to the chipping plant in Wichita.
At the end of the auction one piece of equipment sat in the yard unsold, that being a size sorter/cutter to produce the seed pieces. While I had no use for such an item it did have 4 or so good electric motors on it and many other pieces that I felt I could use/salvage. That said I offered the guy $50 for it and he accepted it just to get it out of his yard.
The machine was 4-5 feet wide and about 10 feet long. Potatoes were dumped into a low hopper at one end and then they traveled down a conveyor of rollers/chains. The openings of the rollers/chain changed spacing as the line moved along. The small potatoes would drop off first, then larger, then still larger, and finally the largest potatoes simply dropped off the end into a bin for hand cutting at a knife station by manual operation.
Each of the sorting points save for the last had automatic cutting. The larger the potato the more blades that cut it into sections with the end result of all seed pieces being of similar size.
I decided the machine was too valuable to waste for salvage and began to inquire around as to replacement rollers as they were rubber covered and hardened with some split.
I learned the mfg. had been out of business several years and that no replacement parts were readily available. Still feeling that the machine needed put to use than salvaged I contacted a vegetable equipment buyer and seller that advertised weekly for equipment to purchase.
I told the buyer what I had, the machine needs, and he offered me $200 via phone. From $50 to $200 for simply bringing the machine home and testing it with a 10# bag of potatoes worked for me. Even though I lost the salvage value of the motors and other parts I preferred to see the machine put back to its proper use rather than junked.
Too bad that I didn't at least take a photo of the machine or better yet have some video taken during the cutting of the 10# test.
This video on YouTube shows a machine that is much larger than the one I had. It doesn't show the cutting operation but does seem to show the size sorting and end product.
