～Mangoku: The Gravity Grain Selector～
information
In short, it is a "large sieve" used to separate high-quality rice from debris and poor-quality grains.
It looks like a large rectangular wooden box with legs consisting of a slide made of fine wire mesh. Here is how it works:
1. Pour the rice from the top
Shelled rice is poured and scattered from the top of the slide.
2. Sliding down
The rice smoothly slides down the slope.
3. Automatic separation!
As they slide, large, high-quality rice grains pass over the wire mesh and reach the very bottom. On the other hand, smaller grains and debris drop down through the gaps in the mesh.
It was a clever machine designed to select only the best-quality rice.
