Hello all,
You are missing a step in the process.
Bakeries typically don’t produce the flour from raw grain. That is done at a mill.
That being said breweries and distilleries use the raw grain in the production of their products.
Grain elevators at the farm end collect the raw product from the producer(s). Then it is shipped; via rail or truck, to the next step in the chain.
For making baked products, that would be the mill for the refining of flour.
For alcohol production that would be directly to the manufacturer.
It would be more prototypical to have grain elevators at the mill, then the flour would be shipped to the baking facilities, again by truck or rail.
A side note- -In North America there are four types of flour milled:
Hard or “Winter” wheat that is used in bread production. This has the highest percentage of the protein Gluten which yields a chewy, elastic texture.
All purpose- -as the name implies a general purpose flour used by most domestic cooks made by blending hard and soft wheat.
Cake flour- -made from soft or “Spring” wheat. This wheat produces a low Gluten content for a more tender product.
Pastry flour- -this is soft wheat flour that has the lowest gluten content. This produces products that are light and flaky.
A large commercial bakery will use all of these types of flour to produce various baked goods.
In Denver, Colorado, there is a large commercial bakery on the east side just south of I-70, there are no grain elevators/silos near this facility.
Golden, Colorado; the home of Coors beer, there are many staging tracks for the incoming raw grain cars and several grain elevators for holding the grain before use.
Perhaps the bakery could be converted to a beer or spirits producer with the grain elevators adjacent to it.
Hope this helps.
