Abstract:
Low temperature process and apparatus generally includes separating whole stillage into thin stillage and wet distillers grains, wherein the thin stillage comprises water soluble proteins in an amount greater than the wet distillers grains, and wherein the wet distillers grains has a higher solid content than the thin stillage; atomizing the thin stillage at an elevated temperature to remove at least a portion of moisture in the thin stillage and form particles and granules of the thin stillage; and removing additional moisture from the particles and granules in a fluidized bed to form dried distillers solubles. The apparatus includes an atomization section and a fluidized bed section configured to dry the thin stillage.
Abstract:
A method of treating a biobased feedstock derived from agricultural resources and specifically from the non-distillate products of fermentation-derived renewable fuel and distilled spirit processes. The separation of thermally labile components from biobased feedstocks result in materials that are thermally stable and better suited for subsequent melt processing in a polymer matrix.
Abstract:
A masterbatch of dried distillers solubles and at least one thermoplastic resin and processes for forming the masterbatch, wherein the dried distillers solubles is greater than 70% by weight of the masterbatch are generally disclosed. The masterbatch generally includes compounding a mixture of dried distillers solubles and at least one thermoplastic resin to form a flowable solid medium, wherein the dried distillers solubles is greater than 70% by weight percent based on a total weight of the mixture and has a moisture content of less than 25% by weight of the dried distillers solubles. The article can then be formed by melt processing, direct injection molding or extruding the flowable solid medium (masterbatch) with an additional amount of at least one thermoplastic resin to form the article, wherein the article comprises dried distillers solubles in an amount of less than 50 weight percent based on a total weight of the article.
Abstract:
A method of modifying a biobased feedstock derived from agricultural resources and specifically from the non-distillate products of fermentation-derived renewable fuel and distilled spirit processes. The pyrolytic modification of biobased feedstocks results in materials that are thermally stable and better suited for subsequent melt processing in a polymer matrix.
Abstract:
A dried distiller soluble based biopolymer, processes for forming the biopolymer, and articles of manufacture thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities and is comprised in part of water-soluble proteins. A biopolymer consists essentially of dried distillers solubles, and an article of manufacture includes a biopolymer consisting of dried distillers solubles and an optional additive. The process of forming dried distiller solubles involves separating whole stillage into a liquid fraction and a solid fraction, wherein the liquid fraction comprises water soluble proteins in an amount greater than the solid fraction, and wherein the solid fraction has a higher solid content than the liquid fraction. The liquid fraction is sprayed at an elevated temperature to remove at least a portion of moisture in the liquid fraction and form particles and granules of the liquid fraction. Addition moisture is removed from the particles and granules in a fluidized bed to form dried distillers solubles, wherein the particles and granules are heated to a temperature less than 300F and have a residence time effective to reduce the moisture content of the dried distillers solubles to less than 20 percent to greater than 3 percent by weight.
Abstract:
A dried distiller soluble based bioadhesive composition and method for producing the dried distiller soluble based bioadhesives are disclosed, as well as derivatives thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities, and is advantageously comprised in part of water-soluble proteins. The method for producing the dried distillers solubles generally involves separation and/or introduction of targeted constituents and/or physiochemical treatment to facilitate use as an adhesive. Use of the method and bioadhesive compositions disclosed herein will improve the economics of fermentation by increasing co-product value, reducing plant-wide energy utilization, decreasing waste and emissions, and increasing overall product yield from each bushel of corn consumed.
