Can You Recommend Literature on the Wet Milling Process for Corn Processing?

[Sandwolf]

I am doing a project on the wet milling process for processing corn into CSL, oil, protein, fibre and starch. It seems that there are a lot of big wet milling plants out there, but I am struggling to find detailed information about the process.

Is there anyone that can recommend some literature? I am particularly interested in the corn steeps and the CSL evaporator.

STEEPING
Each stainless steel steep tank holds about 3,000 bushels of corn for 30 to 40 hours of soaking in 50 degree Celsius water. During steeping, the kernels absorb water, increasing their moisture levels from 15 percent to 45 percent and more than doubling in size. The addition of 0.1 percent sulfur dioxide to the water prevents excessive bacterial growth in the warm environment. As the corn swells and softens, the mild acidity of the steepwater begins to loosen the gluten bonds within the corn and release the starch. After steeping, the corn is coarsely ground to break the germ loose from other components. Steepwater is condensed to capture nutrients in the water for use in animal feeds and for a nutrient for later fermentation processes. The ground corn, in a water slurry, flows to the germ separators.

Does anyone know the test to check for germ breakage in a corn wet milling plant?
If so please let me know the details.
