Abstract: A process for recovering waste liquid from the distillation of fermented rice liquor. After filtration of the waste liquid, the residue can be recovered as dry feed, and the filtrate which contains about 4-5% crude protein, 1% starch and 92 wt. % water is first concentrated to lower the water content to about 70-80 wt. %. The filtrate is then dried with a spray dryer to produce nutritious dry feed while a suitable chelating agent such as magnesium hydroxide is used to prevent the clinging of the product on the wall of the dryer.

Abstract: A process for manufacturing flavors from the spent mash of a fermentation mixture is provided wherein the spent mash of the fermentation mixture after distillation is separated into two constituent portions, the thin stillage and the wet distillers' grains. The thin stillage portion is then combined with a base to adjust pH thereof to between about 7 and about 11. The pH-adjusted thin stillage portion is then cooked at a temperature between about 130.degree. F. and about 210.degree. F. for a period of about 4 to about 14 hours. The cooked solution is concentrated in an evaporator until about 30% wt. solids level is obtained. The product is then dried to about 5-about 10% wt. moisture content. The product obtained has different flavors, depending on the base added and the pH of the cooking step. If the base is sodium hydroxide, the product has a bland, sweet or yeasty flavor if the pH is 8.5, maple or caramel flavor if the pH is 9.5, and a cracker or nutty flavor if the pH is 10.5.

Abstract: A livestock feed supplement providing high by-pass protein, being substantially free of urea and molasses, and providing good palatability. The supplement is formulated using byproducts of grain alcohol fermentation, namely distillers dried grains obtained from the stillage of fermented, dry-milled whole grain, and condensed distillers solubles from such stillage. Standard amounts of other nutritional supplements, including vitamins and minerals, are added to the composition to form the block. The supplement may be compressed and cured into a substantially hard block for free-choice feeding, or packaged in its granular, somewhat moist form for subsequent mixing in livestock feed. The byproducts of the fermentation include natural flavors that provide good palatability without the addition of sweeteners such as molasses.

Abstract: The invention is a method for preparing a bran from wet distiller's grain (WDG) or distiller's dried grain with solubles (DDGS). In the method sodium bicarbonate, amino acid and potato starch are added to the wet, solid residue from the fermentation of grain. Then, the residue-additive mix is blended and dried to produce a bran which may be utilized on a 50-50 weight basis with wheat flour, for example, in the manufacture of noodles and baked goods.

Abstract: An energy-efficient method of recovering roughage from brewery residues (draff), including adding water to the draff and mixing to form a mixture of a soft protein fraction and a hard roughage fraction, separating the soft protein fraction from the hard roughage fraction, and removing water from the separated roughage fraction. After separating water the roughage fraction may be dried, and comminuted. In contrast to other methods, the separation into roughage and protein fractions is performed before the drying step and only the roughage fraction of interest is dried.

Abstract: Pre-heated mash is pelleted. The resulting warm pellets are cooled by the ambient air and the ambient air is heated by the warm pellets. The heated ambient air is used to pre-heat the mash.

Abstract: A high quality animal feed stuff is produced by thermal dewatering of liquid stillage obtained from fermentation of grain raw material and distillation of the fermentation product. The liquid stillage is mixed with particles of already dewatered product and the mixture is granulated in a granulation device to form essentially spherical granules with a dry substance content of 50-70% by weight, the major part of the granules having a particle diameter in the range of 2-6 mm, whereafter the granules are dried by being conveyed as a porous bed in a controlled path in contact with hot gas of a temperature less than 100.degree. C., and whereafter a part of the dried granules with a desired particle size are discharged and the remaining part of the granules after possible disintegration are recirculated to the granulation step.

Abstract: In the brewing of beer, spent grain at about 90% moisture from a straining tank having no internal rotating rake is collected and pumped to a centrifuge which reduces the moisture of the spent grain to about 70% and provides spent grain liquor of about 2.0 to 4.5% or more of total solids. The spent grain liquor is stored in a tank at 165.degree. F. to 170.degree. F. and held until it is used up to 50% of the sparge liquid for a subsequent brew in the straining tank. The spent grains at about 70% moisture are directed to a large holding tank. Nutritious brewery waste streams are added thereby increasing the nutritional value.

Abstract: An improved two step method for producing feeds for ruminant animals whereby carbamides, particularly urea and biuret, are reacted with fermented proteinaceous agricultural products and wastes with the aid of an aliphatic dicarboxylic acid catalyst to produce a highly palatable nutritive feed which releases protein and protein equivalent nitrogen in a slow and controlled manner in the rumen.First stage of the method mechanically destroys the cellular structure of the fermented agricultural products and wastes, removes unpalatable acids, aldehydes and amines by stripping with hot gas, and partially completes the adduct-forming reaction between proteinaceous sugars, fats, and cellulose in the fermented material and the carbamides in a homogeneous liquid phase at temperatures of between 80.degree. and 100.degree. C. In the second stage, adduct reaction and drying is completed in a hot gas fluidized reactor at temperatures between 100.degree. and 150.degree. C.
