Rice polishing machine

I need a machine that can polish rice to low % without cracking them. It's near impossible and/or prohibitively expensive to buy something like this for your home, so I will be making it myself.

Anyways... how the FRICK can I go about this?

    Look up what it's called in Japanese and watch videos.

      Rice polishing machine = seimai-ki. Picrel is what they look like. The big funnel holds the rice and directs it into a set of stone wheels. The spinning stone wheels nick the rice and take off some of the outer layer. Of course these are much larger than one that I could build.

      Watching videos doesn't help a ton in figuring out how to make one though.

        I can't imagine this would be too expensive to buy, but if it is, then getting some sheet metal laser cut and welding it up into a bowl, then putting it on a motor is basically the entire setup.

        This one is just a spinny thing and a wire mesh.

          Those aren't that expensive. It might be possible but I'm not sure if it would work that well in terms of going below 50%. Plus these things aren't meant to operate for a long time. Might be worth a shot though

          What if you used a stone tumbler?

          I'm not sure. Maybe it could work? I think any sort of liquid lubricant would be a problem.

            Well if you need large quantities then your best bet is probably just buying a chink industrial machine for $1k or so. You're not going to save money PrepHoleing something on this scale unless you have extensive metalworking equipment at home, and even then, the time it takes to make a working product isn't going to be worth it.

              If I could just drop 1k and be done I would. But it’s more of a “call for price” type deal. I don’t know if you can even buy one without speaking Japanese.

              The cheapshit ones on alibaba or whatever are meant for table rice, not sake. I don’t know if they can do what I want and I’m hesitant to drop thousands on a piece of crap that might not even work for my needs.

    Lol, we use a blunt piece of wood, place the rice in another piece of wood with a depression in it, beat on it, blow off the chaff, and repeat. Easy and cheap.
    Also, you should leave some of the bran, it’s good for you.

      Hand pounding doesn't even get you to the ~90% rice polishing ratio of regular grocery store rice. I need less than 50%.

        Just grind it into micro-fine powder and throw it away. Same result.
        Imagine being fooled by some stupid rice-wasting rice industry myth so you buy more.
        If the shampoo bottle told you to wash, lather, rinse 17 time I’m sure you would be all over it.

      Junmai Daiginjo Sake. Polished rice is hard to get a hold of in the US. There are only a few companies that even produce it. Your selection is extremely limited both in terms of polish % and in rice varietal, and the price is astronomical, not to mention the shipping costs.

      That would certainly crack the rice. It needs to happen gently over a long period of time. Depending on the type of rice, it can take over 3 days to polish down to 35%.

                Isn't this just a specialized grain mill? Doesn't seem like it should be that hard to build, since it's just a hopper than feeds the rice to the millstone and a way for it to be collected after.

    Hey I'm gonna post here before making my own thread because my question is also rice related, and I need some advice bros.
    I work at a Japanese restaurant as a dish slave and I'm trying to devise a preventive measure to prevent rice from falling through the drain because it tends to clog the pipes quite horrifically. I have been pouring the rice from the cooking pot into a strainer then throwing away the rice into a trash, however my dad suggested we could place a mesh screen with handles halfway up from the bottom as well as a strainer basket for the plughole. Any suggestions?

      you can get plughole guards but a bit of mesh would also work

        Does it matter what size the guard has to be or are they generally universal? I want to order it now online before going in but I don't know the diameter

    What is the reasoning behind polishing rice? I have never heard of this before in my life until this thread...

    • 3 weeks ago

      >for eating
      Polishing brown rice removes the bran to make white rice. Brown rice will go bad a LOT quicker than white rice. White rice also cooks faster and in less water. Arsenic is also more concentrated in the bran.

      >for sake
      The outer layers of rice contain a lot of fats, proteins, nutrients etc. which can lead to more “off”/harsh flavors in your sake. Generally a more polished sake will have a lighter and more refined flavor profile. This doesn’t necessarily mean that low seimai-buai is better, but it does have a different taste.

    I'd try tossing it into a cement mixer with sand and/or fine gravel as abrasive.
    No way to control grain size other than timing, but i imagine it would turn out pretty consistent.

      Obviously wouldn't work for eating, but might actually be practical for sake, as you'd have filtering/decanting steps to remove grinding media

      I've seen people theorize about something similar, using talcum or glucose powder. But I'm not sure about this method, as it requires water which would screw with the pre-steaming soak time.
