Primary processing of cereals includes cleaning, grading, hulling, milling, pounding, g rinding, tempering, parboiling, soaking, drying, sieving. Secondary processing of cereals (or 'adding value' to cereals) is the utilisation of the primary products (whole grains, flakes or flour) to make more interesting products and add variety to the diet.

Rainer Höfer, in Industrial Biorefineries & White Biotechnology, 2015. 8.2.1.2 Corn Dry Milling. Corn dry milling operations are specially designed to manufacture fuel-grade ethanol in a "one-shot" process directly from the whole corn kernels. For this purpose, shelled corn arrives at the dry-mill processing facility and through processing via a hammer mill the entire corn kernel is ...

If you were to calculate bushel yield, it would be 2.22, since 450,000 pounds equals 4,500 cwt and 10,000 bushels divided by 4,500 cwt equal 2.22. The lower the bushel yield the more efficient the milling process. Extraction is simply calculating the percentage of flour produced. For instance, 10,000 bushels equals 600,000 pounds of wheat (at ...

The milling process usually comprises of a few different operations but this depends on the shape of the final product and the state of the raw piece. Often, milling is necessary for giving a precise finish and adding a few features like slots or threaded holes. But it is also suitable for creating a finished part from a block of material.

1.5.3 Wet Processing. The wet-milling methods use water for fiber extraction but differ in the reagents and conditions employed. There are different wet-milling methods, such as conventional, alkali, enzymatic, and modified wet milling. The conventional wet-milling process involves the soaking of raw materials in a sulfuric acid solution.
