AI Thread Summary
The discussion centers on the wet milling process for corn, specifically focusing on the production of corn steep liquor (CSL), oil, protein, fiber, and starch. The steeping phase is highlighted, where corn is soaked in water at 50 degrees Celsius for 30 to 40 hours, leading to significant moisture absorption and swelling of the kernels. The process involves adding sulfur dioxide to prevent bacterial growth, which aids in loosening gluten bonds and releasing starch. After steeping, the corn is coarsely ground, and steepwater is condensed for nutrient recovery. The participant seeks literature recommendations on the wet milling process, particularly regarding corn steeps and CSL evaporators, and also inquires about testing for germ breakage in wet milling plants. Various resources and links are provided for further exploration of the wet milling process and comparisons with dry milling.

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 reccomend 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.
