  • Patent number: 10655083
    Abstract: In one aspect of the invention, a method recovers oil from a concentrated byproduct, such as evaporated thin stillage formed during a dry milling process used for producing ethanol. The method includes forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct. Further, the step of separating the oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil from thin stillage.

  • Patent number: 9284421
    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.

  • Patent number: 9139627
    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.

  • Patent number: 9108140
    Abstract: In one aspect of the invention, a method and related system efficiently and effectively recover a significant amount of valuable, useable oil from byproducts formed during a dry milling process used for producing ethanol. The method may include forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct using a multi-stage evaporator, as well as recovering the oil before the final stage of the evaporator. Further, the step of recovering oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil.
