    摘要: 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.

    摘要: Systems and methods for producing carbohydrate (e.g., sugar) streams (and recycling enzymes) from a pretreated or untreated biomass such as cellulosic feedstock, including, for example, “brown stock” feedstock, or waste or recycled fiber sludge produced in the pulp and paper industry, such as for biochemical (e.g., biofuel) production, are provided. In one example, the system and method can produce high purity C6 (glucose and/or fructose) and/or C5 (xylose) sugar streams, and other carbohydrates and/or fibrous materials, from cellulosic feedstocks, such as brown stock or waste fiber sludge, that can be effectively converted into various biochemical products, such as ethanol.

    摘要: An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biofuel production, using membrane filtration. In particular, a sugar/carbohydrate stream, which includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose (aka glucose) and/or has had removed therefrom an undesirable amount of unfermentable components, can be produced after saccharification and prior to fermentation (or other sugar conversion process) using membrane filtration, with such sugar stream being available for biofuel 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, oil and/or fiber, prior to fermentation or other conversion systems. In other words, sugar stream production and/or grain component separation occurs on the front end of the system and method.

    摘要: A system and process is disclosed for adding pre-fermentation separated non-fermentables, e.g., fiber, germ/oil, and/or protein, to a post-fermentation stream in a corn (or similar carbohydrate-containing grain) dry milling process for making alcohol and/or other biofuels/biochemical. The process includes mixing grain particles with a liquid to produce a slurry having starch and non-fermentables. The slurry is subjected to liquefaction to convert the starch in the slurry to complex sugars and produce a liquefied stream including the complex sugars and non-fermentables. After liquefaction but prior to fermentation of simple sugars resulting from conversion of the complex sugars, the non-fermentables are separated out to define a non-fermentables portion and an aqueous solution including the complex and/or simple sugars. The simple sugars are fermented to provide a fermented stream. Then, the separated non-fermentables portion is reincorporated back into the process into a post-fermentation stream. In one example, the non-fermentables may be mainly fiber.

    摘要: The present invention relates generally to corn dry-milling, and more specifically, to methods for producing a high protein corn meal from a whole stillage byproduct produced in a corn dry-milling process for making ethanol and a system therefore. In one embodiment, a method for producing a high protein corn meal from a whole stillage byproduct includes, in a corn dry-milling process for making ethanol, separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion. The thin stillage portion is separated into a protein portion and a water soluble solids portion. Next, the protein portion is dewatered then dried to define a high protein corn meal that includes at least 40 wt % protein on a dry basis.
