Here, some of the large-scale cleaners are seen: a clipper cleaner, which uses sieves to remove foreign matter from wheat, is on the right. A disk separator, which segregates wheat by size, is on the left in the foreground and a scourer, which removes dust from wheat, is in the left background. The wheat is transported from one machine to the next through the yellow pipes by high velocity air.
After the wheat has been cleaned and bottled, moisture analysis, protein analysis and grain hardness tests are conducted. The results of these tests are used to prepare the wheat for experimental milling.
