Abstract

An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biochemical production. In particular, after saccharification and prior to a sugar conversion process, a sugar/carbohydrate stream is removed from a saccharified stream. The sugar/carbohydrate stream includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose can be produced, with the such sugar stream being available for biochemical production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein and/or fiber. Sugar stream production occurs on the front end of the system and method.

Claims27

Dependent claims

A method for producing a sugar stream comprising:

mixing ground grain particles with a liquid to provide a slurry;
separating the slurry into an initial solids portion and an initial liquid portion,
subjecting the initial solids portion to liquefaction to provide a first liquefied starch solution including starch and the initial solids and subjecting at least a portion of the initial liquid portion to a separate liquefaction step to provide a second liquefied starch solution including starch;
thereafter, subjecting the second liquefied starch solution to saccharification to convert the starch to simple sugars and produce a saccharified stream including the simple sugars;
and
after saccharification of the second liquefied starch solution but prior to further processing of the simple sugars, separating the saccharified stream into a solids portion and a liquid portion including the simple sugars,
wherein, prior to separating the saccharified stream into the solids portion and the liquid portion, the separated initial solids remain separate from the saccharified stream of the second liquefied starch solution and wherein the separated liquid portion from the saccharified stream defines a sugar stream having a dextrose equivalent of at least 20 DE and a total unfermentable solids fraction that is less than or equal to 30% of a total solids content.
