Milling Your Rice/自分で精米するには

Can you tell what this is?

This brown paper bag contains 30 kg brown Koshihikari rice. The rice was given to me by a brother-in-law.

There are not many Japanese, including farmers, who have a rice milling machine in their houses, and I am no exception. How should I mill the rice, then? That's easy!

All I need to do is to take the bag to a rice milling station and mill the rice by myself.

Such milling stations are everywhere in rural areas of Japan.

You first put your rice in the hopper. By the way, this particular milling machine is quite sophisticated; when I stood in front of it, a woman's voice was heard, asking to put the rice in.

The sign says you must not put in white rice (naturally!), wet rice, worm-eaten rice, and so on.

Then, you put 100 yen per 10 kg. Then, press one of the buttons: No-wash, super white, standard, and 70%-milled. I pressed the Standard button, as usual.
次に、10キロにつき100円入れます。次に、次のうちどれかボタンを押します: 無洗米(むせんまい)、上白(じょうはく)、標準(ひょうじゅん)、七ぶ(しちぶ)。私は、いつも通り、標準を押しました。

Your rice comes out, milled.

It takes about 3 minutes to mill 30 kg of rice.

This particular milling machine is really sophisticated. I have never seen a machine that can produce no-wash rice! I think I'll try the no-wash button the next time.

Resultant white rice:

When milled, brown rice will lose 10% of its weight. Thus, 30 kg of brown rice will result in 27 kg of white rice.

Fantastic. Trust Japanese ingenuity! Does self-milled rice taste any better? :)

Chee Fai: I can't answer your question directly. I have never made a side-by-side comparison with rice milled with a small-size, home-use milling machine (I don't have one!). The last time I went to this milling station to mill my rice, it had a sophisticated, low-temperature milling machine. It was capable of milling rice at low temperature so as not to impair the flavor of the rice. I guess the present machine is even more sophisticated.
Ideally, I should mill only 10 kg of my rice, and use it up within two weeks before it gets smelly, but I don't want to make frequent trips to the milling station, so I usually end up milling the whole bag.

This is so interesting! How does the taste of the "milled to order" rice compare with pre-milled rice that one would buy at the grocery store?

Nancy: I can't give you an definite answer. I guess that such rice milling machines are as good as or perhaps even better than commercial, much bigger ones. Obviously, there are a number of advantages to milling rice at one of those rice milling stations by yourself. For example, you can mill your rice and cook it on the same day, and you can select a "milling ratio". (The previous machine installed in that particular station had a "50%-milled" button as well.)
