Well I have to admit failure on this one. I have tried several varieties of rice and the listed polish rate is now where close to the actual rate I get when running rice through the machine. I tried running 2 lbs of rice (full hopper) through the machine and even with brown rice it took 12 passes to get a 20% polish rate. This was the best polish rate I could get. This is not even near the 30-40% polish rate that was listed for the unit.
I can't tell you how disappointed I am with this whole situation. Now I have to convince the seller to take the unit back and HOPEFULLY refund my money. I have emailed them tonight, but I have a feeling that I am just royally screwed on this one. This was a huge investment in time and money and I think I am going to lose big time. Hopefully my wife will be somewhat understanding.
I think the next option will be to some how find out how some of the industrial polishers work and try to build a smaller version. If anyone has any leads I would appreciate it. I am totally bummed at the moment, but I have not given up hope for producing Daiginjo sake!
