The present invention relates to a method of treating a raw feed material, the method comprising a grinding step, an enzymatic treatment step, and a drying step, wherein the raw feed material is ground to obtain a meal in the grinding step, water is added and mixed into the meal to obtain a mixture, which is then subjected to an enzymatic treatment step with an enzyme preparation, to obtain an enzymatically treated mixture. The enzymatically treated mixture is dried in the drying step. The grinding process is adjusted in such way as to deliver a meal that has a particle size, measured as d50, between ≥100 μm and ≤1000 μm, whereas water is added to achieve a total water content of between ≥15% w/w and ≤40% w/w.

The present disclosure relates to methods and systems for making one or more antimicrobial compositions and/or one or more virucidal disinfectant compositions. Said methods and systems include exposing a vegetable oil composition to ozone gas to cause ozonolysis of on one or more unsaturated fatty acids present in the vegetable oil composition, thereby forming an ozonated vegetable oil composition and exposing the ozonated vegetable oil composition to a temperature greater than 60° C. while in contact with water to decompose one or more ozonide compounds and form a heat-treated, ozonated vegetable oil composition. The present disclosure also relates to one or more uses of said one or more antimicrobial compositions and/or one or more virucidal disinfectant compositions.

The invention relates to a method for the simultaneous production of a fermented, solid product and ethanol comprising the following steps: 1) providing a mixture of milled or flaked or otherwise disintegrated biomass, comprising oligosaccharides and/or polysaccharides and live yeast in a dry matter ratio of from 2:1 to 100:1, and water; 2) fermenting the mixture resulting from step (1) under conditions where the water content in the initial mixture does not exceed 65% by weight, for 1-36 hours at a temperature of about 25-60° C. under anaerobic conditions; 3) incubating the fermented mixture resulting from step (2) for 0.5-240 minutes at a temperature of about 70-150° C.; and 4) separating wet fermented, solid product from the fermented mixture resulting from step (3); further comprising either a) that the fermentation in step (2) is performed in one or more interconnected paddle worm or continuous worm conveyers with inlet means for the fermentation mixture and additives and outlet means for the ferment as well as control means for rotation speed, temperature and pH, or b) that one or more processing aids are added in any of steps (1), (2) and (3) and further comprising a step of 5) separating crude ethanol from the fermented mixture in step (2) by vacuum and/or in step (3) by vacuum or by injection of steam and condensing the surplus stripping steam. The invention further relates to the products of this method as well as uses thereof.

The present technology provide a method of dewatering whole stillage. The addition of a xylanase in combination with a pectinase results in a wet cake with a higher dry mass. The advantage here is less energy consumption while drying.

A feed composition for ruminants may include feed particles that contain a saturated fatty acid component as well as a urease inhibitor such that ingestion of the feed by lactating ruminants may provide for an increase in the amount of milk produced by the ruminant and/or an increase in the fat content of the milk produced, and a decrease in ammonia production from breakdown of urea.

Systems and methods are provided for separating high value by-products, such as oil and/or germ, from grains used for alcohol production. In one embodiment, a method for separating by-products from grains used for alcohol production includes, subjecting milled grains to liquefaction to provide a liquefied starch solution including fiber, protein, and germ. The germ is separated from the liquefied starch solution. The separated germ is ground, e.g., to a particle size less than 50 microns, to release oil to provide a germ/oil mixture. Then, prior to fermentation, the oil is separated from the germ/oil mixture to yield an oil by-product. The pH of the germ/oil mixture can be adjusted to about 8 to about 10.5 and/or cell wall breaking enzymes or chemicals may be added to help release oil from the germ. In one example, the oil yield is greater than 1.0 lb/Bu.

A multi stage process for separating oil, protein, fiber and clean water from a stream containing whole stillage byproduct from ethanol production is disclosed. In a first step, fibers are separated in a two-step process that includes a plate separator and a press. In a subsequent step, the liquid stream separated from the fibers and contains oil, protein and water is treated with a composition that causes the protein to gel. The liquid stream is then processed in a phase separator that drains the oil by gravity, removes the water by an impeller under pressure and removes the solidified protein using a scroll.
