Abstract
The present disclosure provides a two-step liquefication (e.g., using a high (>23 Be) and a low Be (<5 Be) liquid media) process in a dry milling process/plant. The dry milling process comprises liquifying starch from milled corns making a liquefied starch slurry in a first liquefication tank having a slurry >23 Be, performing a first solid/liquid separation using a first paddle screen after the liquifying starch, soaking, cooking, or degrading protein in a second liquefication tank with a slurry <5 Be, and performing a second solid/liquid separation using a second paddle screen after the soaking, cooking, or degrading protein in a second liquefication tank.

1-9. (canceled)
10) A dry milling process comprising:
- a. liquifying starch from milled corns making a liquefied starch slurry in a first liquefication tank having a slurry of 20-27 Be;
- b. performing a first solid/liquid separation using a first paddle screen after the liquifying starch;
- c. soaking, cooking, or degrading protein in a second liquefication tank with a slurry <5 Be;
- and
- d. performing a second solid/liquid separation using a second paddle screen after the soaking, cooking, or degrading protein in a second liquefication tank.
18-30. (canceled)
31) A dry milling process comprising:
- a. liquifying starch from milled corns making a liquefied starch slurry in a first liquefication tank having a slurry of 20-27 Be;
- b. performing a first solid/liquid separation using a first paddle screen after the liquifying starch;
- c. soaking, cooking, or degrading protein in a second liquefication tank with a slurry <5Be;
