Why is the invention " Astrié " unique?


Is your time precious? You have less than a minute? Here is a video summary of this article:


The grinding wheel attachment system

In a “Moulin Astrié” type stone mill, there are two millstones:

  • the so-called “dormant” fixed wheel

  • the so-called “flying” oscillating wheel

And it is the attachment system of the "flying" grinding wheel that is innovative.

Indeed, the flying wheel is not fixed, it is hung thanks to an oscillating system.

It is therefore not the weight of the flying millstone that will crush the seed to make flour, but it is the gap between the fixed millstone and the flying wheel which will allow the seed to be unrolled to extract the germ and all its components.

It is therefore the gap between the millstones that will determine the grind.

Depending on the grind you want, you will be able to adjust the distance between the wheels. In this video we have recorded the way the flying wheel oscillates so that you understand in picture.


How to adjust the gap between the grinding wheels?


Nothing could be simpler!

You have a crank that allows you to move the grinding wheels closer together or further apart. We explain it in this video:


Why the fact that the seed is not crushed but "unrolled" will change everything?

To make a quick summary, the fact that your seed is unrolled and no longer crushed will allow you to obtain a flour that:

  • retains all its nutritional qualities

  • is more digestible

  • is more nutritious

  • is a local flour

  • is unoxidized

  • has greater added-value

Techniques borrowed from milling to make a coherent mill

Beyond this invention, which we owe purely and simply to the Astrié brothers (who gave the name to this type of stone mill), there is also an overall reflection on the mill.

Indeed, Pierre and André Astrié knew the world of milling and milling well, so they borrowed different techniques and technologies specific to different tools to make a coherent mill.

For example, they were inspired by other machine tools to offer:

  • one-handed flow adjustment

  • sifting

  • sieve change possible in a jiffy

All these techniques and solutions make it possible today to make a machine (the stone wheel mill known as “Moulin Astrié”) that is consistent, reliable, robust with practically no after-sales service.
