In a flour factory, the production process circulates in a vertical fashion from one floor to another. The product is elevated using a belt bucket elevator and descends through inclined wooden conducts, constantly going up and down. The construction of this tube system involved a precise calculation of the inclination of each of them.

The belt bucket elevator consists of two vertical boxes that are joined at the top and bottom with a pulley, through which a belt passes equipped with buckets, allowing the wheat and other products to be lifted.
